Description

  The present invention relates to a radiographic image capturing system, and more particularly to a radiographic image capturing system capable of displaying a preview image of an image captured by a radiographic image capturing apparatus.

  For the purpose of disease diagnosis and the like, radiographic images taken using radiation typified by X-ray images are widely used. Conventionally, such medical radiographic images have been taken using a screen film. In order to digitize radiographic images, CR (Computed Radiography) devices using stimulable phosphor sheets have been developed recently. Then, a radiation image capturing apparatus has been developed in which irradiated radiation is detected by a radiation detection element arranged in a two-dimensional form and acquired as digital image data.

  This type of radiographic image capturing apparatus is known as an FPD (Flat Panel Detector), and is conventionally formed as a so-called dedicated type radiographic image capturing apparatus formed integrally with a support base (for example, Patent Documents). 1). However, in recent years, a portable radiographic imaging apparatus in which a radiation detection element or the like is accommodated in a housing has been developed and put into practical use (see, for example, Patent Documents 2 and 3). In such portable radiographic imaging apparatuses, a radiographic imaging apparatus that has a built-in battery and that transmits and receives signals and data by exchanging radio waves via an antenna apparatus has been developed (for example, Patent Document 4). Etc.).

  In addition, as a radiographic imaging apparatus, a so-called direct type radiographic imaging apparatus that generates a charge in a detection element in accordance with a dose of irradiated radiation such as X-rays and converts it into an electric signal, or irradiated radiation A so-called indirect type in which after being converted into electromagnetic waves of other wavelengths such as visible light with a scintillator or the like, electric charges are generated by photoelectric conversion elements such as photodiodes in accordance with the energy of the converted and irradiated electromagnetic waves and converted into electric signals Various radiographic imaging devices have been developed. In the present invention, the detection element in the direct type radiographic imaging apparatus and the photoelectric conversion element in the indirect type radiographic imaging apparatus are collectively referred to as a radiation detection element.

  By the way, when photographing a subject such as a patient with such a radiographic imaging device, before the final radiographic image is generated by transmitting the captured image data to a console or the like and performing full-scale image processing, , Whether or not the subject is properly captured in the image, that is, whether or not the subject is originally photographed and whether or not the subject in the image is positioned is determined to determine whether or not re-shooting is necessary It is necessary to do.

  For this reason, image data obtained by radiographic imaging is transmitted to a console or the like to display an image, and a radiographer or other radiographer confirms the displayed image to determine whether re-imaging is necessary. Often configured.

  At this time, if all the image data obtained by radiographic imaging (that is, so-called raw data) is transmitted to the console, it takes time to transmit the data, and it takes a long time to display the image. However, it takes a long time to display an image, and if it is determined that it is necessary to re-photograph, there is a problem that the patient has to wait for a long time and the burden on the patient is increased.

  Therefore, as described in, for example, Patent Document 5, for example, with a radiographic imaging apparatus, thinned data is generated by thinning data from an image data at a predetermined rate to reduce the data amount, and transmission of all image data is performed. Earlier, the thinned data can be configured to be sent to the console. With this configuration, it is possible to quickly display a preview image based on the thinned-out data on the console, and the time for waiting for the patient to determine whether or not re-imaging is necessary based on the positioning confirmation of the subject is shortened. There are advantages such as being able to reduce the burden on the patient.

Japanese Patent No. 3639750 JP 2006-058124 A JP-A-6-342099 JP-A-7-140255 JP 2010-213917 A

  By the way, when considering the actions of the photographer in radiographic imaging (that is, the flow of work), the radiographer or other radiographer first adjusts the positional relationship between the patient, the radiographic imaging device, the radiation source, etc. in the radiography room. After that, it moves to the front room (also referred to as an operation room or the like) and operates an exposure switch provided in the radiation generator to irradiate the subject as a patient from the radiation source.

  Then, it waits in the front room until the preview image is displayed on the display section of the console provided in the front room, and when the preview image is displayed a few seconds after the radiation irradiation ends, it is confirmed and replayed. The necessity of shooting is determined.

  However, for example, when taking multiple shots of the same patient and shooting different parts of the patient's body, the patient immediately returns to the imaging room and changes the patient's pose each time irradiation is completed. There are many photographers who want to start preparations for the next imaging as soon as possible.

  In such a case, the photographer may feel uncomfortable or frustrated when the user has to wait until the preview image is displayed in the anterior room even after the irradiation is completed, or the radiographic image There is a risk that the shooting system may feel unusable.

  The present invention has been made in view of the above-mentioned problems, and it is possible for a radiographer or other photographer to immediately move to the radiographing room after radiation irradiation and start preparation for the next radiographing.

When the thinning data is transmitted from the portable radiographic image capturing device, the repeater transmits the thinning data to the set display unit, and displays a preview image based on the thinning data on the display unit. It is characterized by being displayed.

  According to the radiographic imaging system of the present invention, a photographer operates the exposure switch to irradiate the radiation as in the conventional system, and remains in the front room and is previewed on the display unit of the console. There is no need to wait until the image is displayed, and the photographer can immediately move to the photographing room and confirm the preview on the display means in the photographing room after the radiation irradiation is completed.

FIG. 1 is a diagram showing an overall configuration of a radiographic image capturing system common to each embodiment of the present invention described below.

  The imaging room Ra is a room that irradiates a subject that is a part of the patient's body (that is, the imaging region of the patient) and performs radiographic imaging, and generates radiation from a radiation irradiation device that irradiates the subject with radiation. A radiation source 52 of the apparatus 57 is disposed. Note that the imaging room Ra is shielded with lead or the like so that radiation does not leak outside the imaging room.

  In each of the following embodiments, a portable radiographic image capturing device 1 as described below is used as the radiographic image capturing device, and the radiographic image capturing device 1 is loaded in the radiographing room Ra. A possible bucky device 51 is provided. The bucky device 51 and the radiation source 52 will be described later.

  Here, first, the portable radiographic imaging device 1 used for radiographic imaging in the radiographic imaging system 50 will be described.

  Hereinafter, the portable radiographic imaging device is simply referred to as a radiographic imaging device. In the following, a so-called indirect radiation image capturing apparatus that includes a scintillator or the like and converts the emitted radiation into electromagnetic waves of other wavelengths such as visible light to obtain an electrical signal will be described as the radiation image capturing apparatus 1. However, the present invention can also be applied to a so-called direct type radiographic imaging apparatus that directly detects radiation with a radiation detection element without using a scintillator or the like.

  FIG. 2 is an external perspective view of the radiographic image capturing apparatus, and FIG. 3 is an external perspective view of the radiographic image capturing apparatus viewed from the opposite side. 4 is a cross-sectional view taken along the line AA in FIG. As shown in FIGS. 2 to 4, the radiographic image capturing apparatus 1 includes a housing 2 in which a sensor panel SP including a scintillator 3 and a substrate 4 is accommodated.

  As shown in FIG. 2 and FIG. 3, a hollow rectangular tube-shaped housing body 2A having a radiation incident surface R in the housing 2 of the radiographic imaging apparatus 1 is made of a carbon plate or plastic that transmits radiation. The housing 2 is formed by closing the openings on both sides of the housing main body 2A with lid members 2B and 2C. Instead of forming the casing 2 as such a so-called monocoque type, for example, a so-called lunch box type formed of a frame plate and a back plate can be used.

  As shown in FIG. 2, the lid member 2B on one side of the housing 2 is composed of a power switch 37, a selection switch 38, a connector 39, an LED for displaying a battery state, an operating state of the radiographic imaging apparatus 1, and the like. The indicator 40 and the like are arranged.

  As shown in FIG. 3, an antenna device 41 that is a communication unit for wirelessly transferring image data D and the like to the console 58 is embedded in the lid member 2 </ b> C on the opposite side of the housing 2. Note that the image data D and the like can be configured to be transferred to the console 58 in a wired manner. In this case, for example, the cable is connected to the connector 39 described above and transmitted and received. In the case where the antenna device 41 is provided, the arrangement location and the number of antenna devices 41 on the housing 2 are appropriately determined.

  As shown in FIG. 4, a base 31 is disposed inside the housing 2 via a lead thin plate (not shown) on the lower side of the substrate 4 of the sensor panel SP. A PCB substrate 33, a buffer member 34, and the like on which are disposed are mounted.

  A glass substrate 35 for protecting the substrate 4 and the scintillator 3 on the radiation incident surface R side is disposed. In addition, a cushioning material 36 is provided between the sensor panel SP and the side surface of the housing 2 to prevent them from colliding with each other.

  The scintillator 3 is attached to a detection unit P, which will be described later, of the substrate 4. As the scintillator 3, for example, a scintillator 3 that has a phosphor as a main component and converts it into an electromagnetic wave having a wavelength of 300 to 800 nm, that is, an electromagnetic wave centered on visible light when it receives incident radiation, is used.

  The substrate 4 is made of a glass substrate. As shown in FIG. 5, a plurality of scanning lines 5 and a plurality of signal lines 6 cross each other on the surface 4a of the substrate 4 facing the scintillator 3. It is arranged to do. In each small region r defined by the plurality of scanning lines 5 and the plurality of signal lines 6 on the surface 4 a of the substrate 4, radiation detection elements 7 are respectively provided.

  In this way, the entire region r in which a plurality of radiation detection elements 7 arranged in a two-dimensional manner (also referred to as a matrix) is provided in each small region r partitioned by the scanning lines 5 and the signal lines 6, that is, FIG. A region indicated by an alternate long and short dash line in FIG.

  Although a photodiode is used as the radiation detection element 7, for example, a phototransistor or the like can also be used. As shown in FIG. 6 which is an enlarged view of FIG. 5, each radiation detection element 7 is connected to a source electrode 8s of a TFT 8 which is a switch means. The drain electrode 8 d of the TFT 8 is connected to the signal line 6.

  The TFT 8 is turned on when a turn-on voltage is applied to the gate electrode 8g via the scanning line 5 from the scanning driving means 15 described later, and is accumulated in the radiation detection element 7 via the source electrode 8s and the drain electrode 8d. The charged electric charge is discharged to the signal line 6. The TFT 8 is turned off when an off voltage is applied to the gate electrode 8g via the connected scanning line 5, and the emission of the charge from the radiation detecting element 7 to the signal line 6 is stopped, and the radiation detecting element The electric charge is held in 7.

  As shown in FIG. 6, the bias lines 9 are respectively connected to the plurality of radiation detection elements 7 arranged in a row. As shown in FIG. 5, each bias line 9 is connected to the detection unit P of the substrate 4. It is bound to one connection 10 at the outer position.

  In addition, each scanning line 5, each signal line 6, and connection line 10 of the bias line 9 are connected to input / output terminals (also referred to as pads) 11 provided near the edge of the substrate 4. As shown in FIG. 7, each input / output terminal 11 includes a flexible circuit board (also referred to as a chip on film) 12 in which a chip such as an IC 12a is incorporated on a film, an anisotropic conductive adhesive film (Anisotropic Conductive Film). And an anisotropic conductive adhesive material 13 such as anisotropic conductive paste (Anisotropic Conductive Paste).

  The flexible circuit board 12 is routed to the back surface 4b side of the substrate 4 and connected to the PCB substrate 33 described above on the back surface 4b side. Thus, the board | substrate 4 part of sensor panel SP of the radiographic imaging apparatus 1 is formed. In FIG. 7, illustration of the electronic component 32 and the like is omitted.

  Here, the circuit configuration of the radiation image capturing apparatus 1 will be described with reference to FIG.

  A bias line 9 is connected to one electrode of each radiation detection element 7, and each bias line 9 is bound to a connection 10 and connected to a bias power supply 14. The bias power source 14 applies a bias voltage (strictly speaking, a reverse bias voltage) to the electrode of each radiation detection element 7 via the connection 10 and each bias line 9.

  The other electrode of each radiation detection element 7 is connected to the source electrode 8s (denoted as S in FIG. 8) of the TFT 8, and the gate electrode 8g (denoted as G in FIG. 8) of each TFT 8. Are connected to the lines L1 to Lx of the scanning line 5 extending from the gate driver 15b of the scanning driving means 15, respectively. Further, the drain electrode 8d (denoted as D in FIG. 8) of each TFT 8 is connected to each signal line 6.

  The scanning drive unit 15 includes a power supply circuit 15a that supplies an on voltage and an off voltage to the gate driver 15b, and a gate driver 15b that switches a voltage applied to each of the lines L1 to Lx of the scanning line 5 between the on voltage and the off voltage. It has. As described above, the gate driver 15b switches the voltage applied to the gate electrode 8g of the TFT 8 via the lines L1 to Lx of the scanning line 5 between the on-voltage and the off-voltage, It is designed to control the off state.

  Each signal line 6 is connected to each readout circuit 17 formed in the readout IC 16. The readout circuit 17 includes an amplifier circuit 18, a correlated double sampling circuit 19, an analog multiplexer 21, and an A / D converter 20.

  For example, when a radiation image is captured, when radiation is applied to the radiation image capturing apparatus 1 through a subject, the scintillator 3 converts the radiation into an electromagnetic wave of another wavelength, and the converted electromagnetic wave is detected immediately below the radiation. The element 7 is irradiated. Then, charges are generated in the radiation detection element 7 in accordance with the dose of irradiated radiation (that is, the amount of electromagnetic wave).

  In the reading process of the image data D from each radiation detection element 7, when an ON voltage is applied to a predetermined line Ln of the scanning line 5 from the gate driver 15 b of the scanning driving unit 15, the line Ln of the scanning line 5 is A turn-on voltage is applied to the gate electrode 8g of each TFT 8 connected to the TFT 8 so that each TFT 8 is turned on, and a signal is transmitted from the radiation detection element 7 connected to each turned-on TFT 8 through each TFT 8. Charge is released to the line 6.

  Then, a voltage value is output from the amplifier circuit 18 in accordance with the amount of charge emitted from the radiation detection element 7, and is correlated double-sampled by the correlated double sampling circuit 19, and the analog value image data D is sent to the multiplexer 21. Is output. The image data D sequentially output from the multiplexer 21 is sequentially converted to digital image data D by the A / D converter 20, output to the storage means 23 and sequentially stored.

  The control means 22 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), a computer having an input / output interface connected to the bus, an FPGA (Field Programmable Gate Array), and the like. ing. It may be configured by a dedicated control circuit.

  The control unit 22 controls the operation of each functional unit such as the scanning drive unit 15 and the readout circuit 17 of the radiographic image capturing apparatus 1. The control means 22 is connected to a storage means 23 constituted by a DRAM (Dynamic RAM) or the like, and a battery 24 that supplies power to each functional unit of the radiographic image capturing apparatus 1. Further, the above-described antenna device 41 is connected to the control means 22.

  When radiographic imaging is performed, the control unit 22 performs a readout process of reading out charges, that is, image data D from each radiation detection element 7 as described above. Further, the control means 22 generates the thinning data Dt for preview by thinning out each image data D at a predetermined ratio based on each image data D read out from each radiation detecting element 7 and stored in the storage means 23. It has become.

  The thinned data Dt is, for example, image data D for one pixel every 3 × 3 pixels or 4 × 4 pixels when each image data D is arranged corresponding to each radiation detecting element 7 arranged in a two-dimensional form. Or the image data D from each radiation detection element 7 connected to each line L1, L4, L7,... Of the scanning line 5, respectively. The image data D from each radiation detection element 7 connected to each line Ln at predetermined intervals may be extracted and created.

  Specifically, for example, each radiation detection element 7 arranged two-dimensionally on the detection unit P as described above is represented as (m, n), and read from each radiation detection element (m, n). When each image data D is represented as D (m, n), for example, as shown by hatching in FIG. 9A, a predetermined number of scans (three in the case of FIG. 9A) are scanned. The scanning line 5 is designated at a ratio of one for each line L1 to Lx of the line 5, and each radiation detection connected to each line L of the designated scanning line 5 as shown in FIG. 9B. Each image data D (m, n) read from the element (m, n) is configured to be thinned data Dt.

  When the radiographic image capturing is completed and the image data D is read from each radiation detection element 7 and stored in the storage unit 23, the control unit 22 immediately creates the thinned data Dt, and the thinned data Dt is a radiographic image capturing apparatus. A cassette ID which is identification information 1 is assigned and transmitted to the console 58 or the like as will be described later. The thinning data Dt is transmitted every time radiographic images are taken.

  FIG. 9B is a diagram for representing an image of a group of thinned data Dt to be created only, and the thinned data Dt does not need to be actually created as a group of data on the storage unit 23. .

  For example, the image data D (1,1), (1,2),... Of each radiation detection element 7 connected to the line L1 of the scanning line 5 is read from the storage means 23 and transmitted immediately, The image data D (4, 1), (4, 2),... Of each radiation detection element 7 connected to the line L4 of the scanning line 5 is read from the storage means 23 and transmitted immediately. Then, this processing is also performed sequentially for the lines L7, L10,... Of the scanning line 5, for example.

  That is, the thinned data is read from the radiographic image capturing apparatus 1 to the console 58 and the like by reading out the image data D from all the image data D stored in the storage unit 23 at a predetermined rate and transmitting it simultaneously with the reading. It can be configured to transmit Dt.

  After transmitting the thinned data Dt to the console 58, the control unit 22 assigns a cassette ID to the image data D that is the basis for creating the thinned data Dt, that is, all image data D obtained by the photographing. It is automatically transmitted to the console 58. At this time, all the image data D including the thinned data Dt may be transmitted again, or, among the image data D, the remaining image data D excluding the thinned data Dt is transmitted. May be.

  As described above, the thinning data Dt is automatically transmitted without waiting for an instruction from the console 58 or the like. However, the transmission of all the image data D is performed at the time when the transmission instruction is issued from the console 58 or the like. It is also possible to configure so that the data is transmitted.

  In addition, when the thinning data Dt is transmitted, when the thinning data Dt is transmitted from the radiographic imaging apparatus 1 to the console 58, the image data D is transmitted from the radiographic imaging apparatus 1 to the console 58. In this case, it is also possible to transmit only the image data D other than the thinned data Dt that has already been transmitted among all the image data D.

  In this case, the console 58 is configured to combine the thinned data Dt that has already been received and the newly transmitted image data D to restore the entire image data D. If the thinned data Dt is directly transmitted from the radiographic image capturing apparatus 1 to an apparatus other than the console 58, the thinned data Dt is not transmitted to the console 58, and therefore the radiographic image capturing apparatus 1 All image data D is transmitted from the console 58 to the console 58.

  Further, as will be described later, when the radiographic imaging device 1 is not loaded into the bucky device 51 and is used alone (that is, when nothing is connected to the connector 39 (see FIG. 2)), the control is performed. The means 22 transmits the thinned data Dt, the image data D, an offset correction value O, which will be described later, and the like to the console 58 via the antenna device 41 in a wireless manner.

  Further, when the radiographic image capturing apparatus 1 is loaded and used in the bucky device 51 (that is, when the connector 51b of the bucky device 51 (see FIGS. 10 and 11 described later) is connected to the connector 39), The control means 22 transmits the thinned data Dt and the like to the console 58 by a wired system via the bucky device 51.

  The control means 22 calculates the offset amount superimposed on the image data D obtained by these radiographic image captures at the end of each radiographic image capture or at the end of a series of radiographic image captures. In order to obtain an offset correction value O for correction, a so-called dark reading process is automatically performed. It is also possible to perform a dark reading process before single or a series of radiographic imaging starts.

  In the dark reading process, each TFT 8 of the radiographic image capturing apparatus 1 is turned off, and left for a predetermined time in a state where the radiation image capturing apparatus 1 is not irradiated with radiation. Then, the dark charges and the like accumulated in them are read out as a so-called dark read value d. The read dark read value d is stored in the storage unit 23.

  Then, the control unit 22 sets the read dark reading value d for each radiation detection element 7 as an offset correction value O, or performs dark reading processing a plurality of times to obtain a plurality of values obtained for each radiation detection element 7. The offset correction value O is calculated, for example, by averaging the dark read values d. Then, a cassette ID, which is identification information of the radiographic image capturing apparatus 1, is assigned to the offset correction value O and is automatically transmitted to the console 58.

  On the other hand, as will be described later, when the radiographic image capturing apparatus 1 is brought into the photographing room Ra, it is inserted into a cradle 55 described later, which is a detecting means. At that time, when the radiographic imaging apparatus 1 is inserted into the cradle 55, the control means 22 will connect the connector 39 (see FIG. 2) to the connector 55a (see FIG. 12 described later) of the cradle 55. A cassette ID which is identification information of the radiographic imaging apparatus 1 is notified to a relay unit 54 (see FIG. 1) described later via 55.

  Further, when the radiographer or other radiographer presses the selection switch 38 (see FIG. 2) as a selection unit, the control unit 22 indicates that the cassette ID, which is its own identification information, has been selected. The selection signal is transmitted to the console 58 via the antenna device 41.

  As will be described later, the radiographic image capturing apparatus 1 has a size compatible with a CR cassette, and can be used by being installed in a later-described Bucky apparatus 51 in a facility.

  Further, when the radiographic imaging device 1 is loaded in the bucky device 51, the radiographic imaging device 1 receives power supply from the bucky device 51, but in a single state not loaded in the bucky device 51, the battery 24 (FIG. 8). The power is supplied to each functional unit such as the control unit 22, the bias power supply 14, the scanning drive unit 15, and the readout circuit 17 (readout IC 16). When the bucky is loaded, transmission of the image data D, control communication, and the like are performed via the bucky device 51 in a wired manner.

  As will be described later, when the radiographic imaging device 1 is loaded in the bucky device 51, the radiographic imaging device 1 is supplied with power from the bucky device 51, but in a single state not loaded in the bucky device 51, Power is supplied from the battery 24 (see FIG. 8) to each functional unit such as the control unit 22, the bias power supply 14, the scanning drive unit 15, and the readout circuit 17 (readout IC 16).

  Then, when the radiographic imaging, the reading process of the image data D, etc. are not performed, if the power is supplied to each function unit, the battery 24 is consumed, so the radiographic imaging device 1 supplies power to each functional unit. Between the state in which the radiographic imaging can be performed by supplying, that is, the imaging possible mode in which imaging is possible, and the sleep mode in which power is not supplied to each functional unit when radiographic imaging is not performed, The mode can be switched.

  In the sleep mode, power is supplied only to functional units that need to be minimally activated such as the antenna device 41 and the control unit 22 so that signals from the console 58 and the like can be received, and the bias power source 14 and the scanning drive unit 15. Power is not supplied to the read circuit 17 (read IC 16) or the like.

  When the power switch 37 (see FIG. 2) is pressed, at least the selection switch 38 is pressed even if the radiographic imaging device 1 is started in the radiographable mode or in the sleep mode is appropriately set. In this case, when the radiographic image capturing apparatus 1 is in the sleep mode, the mode of the radiographic image capturing apparatus 1 is switched to the radiographable mode.

  In addition, the radiographic image capturing apparatus 1 automatically switches the mode to the sleep mode when the predetermined time elapses when the radiographic image capturing is not performed even after the predetermined time elapses after the radiographing mode is switched. It is supposed to switch to.

  Then, when the mode is switched, the radiographic image capturing apparatus 1 transmits a signal indicating that the radiography is enabled or a signal indicating that the sleep mode is set to the console 38 together with its own cassette ID. It is like that.

  Next, other devices in the radiographic image capturing system 50 will be described.

  As shown in FIG. 1, the bucky device 51 can be used by loading the radiographic imaging device 1 into a cassette holding portion (also referred to as a cassette holder) 51a. In FIG. 1, a case is shown in which a shooting device 51 </ b> A for standing position shooting and a bucky device 51 </ b> B for standing position shooting are installed as the bucky device 51 in the shooting room Ra. The present invention is also applied to the case where only the bucky device 51A for position photographing or only the plurality of bucky devices 51B for position photographing are provided.

  Each bucky device 51 is configured such that a conventional CR cassette can be loaded into the cassette holding portion 51a and used, and an existing bucky device installed for the CR cassette in the photographing room Ra can be used. Is possible.

  Therefore, the radiation image capturing apparatus 1 is formed to have the same dimensions as the CR cassette. That is, the CR cassette is formed in a size such as 14 inches × 17 inches (half-cut size) in accordance with the JIS standard size (corresponding international standard is IEC 60406) for conventional screen film cassettes. Further, the thickness in the radiation incident direction is formed to be within a range of 15 mm + 1 mm to 15 mm-2 mm.

  Therefore, in order to enable the use of the JIS standard size CR cassette in the Bucky device 51, the radiographic imaging apparatus 1 also conforms to the JIS standard for the screen film cassette to which the CR cassette conforms. It is formed with the dimensions.

  In addition, when the existing bucky device for a screen / film cassette or a CR cassette is not used, it is not necessary to form the radiographic image capturing device 1 with the above-described dimensions, and the radiographic image capturing device 1 has an arbitrary size and shape. It is possible to form. However, in that case, it is necessary to newly install a bucky device capable of loading the radiographic imaging device 1 having an arbitrarily set shape as the bucky device 51 in the imaging room Ra.

  As shown in FIG. 10, a connector 51b connected to the connector 39 (see FIG. 2) of the loaded radiographic imaging device 1 is provided inside the cassette holding portion 51a of the bucky device 51. This is the same in the bucky device 51B for standing position photography as well as the bucky device 51A for standing position photography shown in FIG.

  As described above, instead of providing the connector 51b inside the cassette holding portion 51a of the bucky device 51, before the radiographic imaging device 1 is loaded into the bucky device 51, as shown in FIG. It is also possible to connect the connector 51b provided at the end of the cable extending from the connector 39 to the connector 39 of the radiographic image capturing apparatus 1 and load the radiographic image capturing apparatus 1 into the cassette holding part 51a of the bucky device 51 in this state. Is possible.

  When the connector 51b and the connector 39 of the radiographic imaging device 1 are connected, the bucky device 51 reads out the cassette ID that is identification information from the radiographic imaging device 1, and the cassette ID of the radiographic imaging device 1 and its own The identification information is associated with a Bucky ID and transmitted to the console 58.

  As described above, the bucky device 51 uses the thinned data Dt output from the radiographic image capturing device 1 via the connector 39 when the radiographic image capturing device 1 is loaded in the cassette holding unit 51a. The image data D and the offset correction value O are transmitted to a repeater 54 described later by a wired method and transmitted to the console 58.

  Further, the connector 51 b of the bucky device 51 and the connector 39 of the radiographic imaging device 1 are connected to supply power from the bucky device 51 to the radiographic imaging device 1. Therefore, when the connectors 39 and 51b are connected to each other, the control means 22 of the radiographic image capturing apparatus 1 stops the supply of power from the battery 24 (see FIG. 8) to each functional unit, and via the connector 39. The power supplied from the bucky device 51 is switched so as to be supplied to each functional unit. It is also possible to charge the battery 24 at the same time while supplying power to each functional unit.

  On the other hand, as shown in FIG. 1, each bucky device 51 is provided with a display means 51c such as a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), etc., which will be described later. As described above, the preview image is displayed based on the thinning data Dt transmitted from the console 58 or the radiation image capturing apparatus 1.

  Each display means 51c may be provided so as to correspond to each Buckie device 51, that is, for example, at a position in the vicinity of each Buckie device 51 or the like, and is necessarily provided directly connected to each Buckie device 51. There is no. In this case, each display means 51c is configured to be connected to a repeater 54 (see FIG. 1), which will be described later, with a cable or the like, for example, and display means from the console 58 or the radiographic imaging apparatus 1 via the repeater 54. The thinned data Dt can be transmitted to 51c.

  As shown in FIG. 1, at least one radiation source 52 for irradiating the subject with radiation is provided in the imaging room Ra. Of the radiation sources 52, one radiation source 52A is arranged suspended from the ceiling of the imaging room Ra, for example, and is activated based on an instruction from the console 58 at the time of imaging, not shown. The moving means is moved to a predetermined position. Then, by changing the irradiation direction of the radiation, it becomes possible to irradiate the radiation image capturing apparatus 1 loaded in the standing position photographing Bucky device 51A or the standing position photographing Bucky device 51B. ing.

  The radiographing room Ra is also provided with a portable radiation source 52B that is not associated with the standing-up radiographing or the supine radiographing apparatus 51A, 51B. The portable radiation source 52B can be carried anywhere in the photographing room Ra, and can irradiate radiation in an arbitrary direction.

  Then, the radiographic imaging device 1 is applied to the body part of the patient who is the subject in a single state (that is, not loaded into the bucky device 51), or the table of the bucky device 51B for lying position photographing or a bed and a patient (not shown). The radiation can be emitted from the portable radiation source 52B at an appropriate distance and direction while being inserted between the body and the body.

  In addition, the radiographic imaging device 1 can be used for radiographic imaging in a single state that is not loaded in the bucky device 51 as described above.

  The radiation source 52 includes an X-ray tube, and when the X-ray tube is supplied with a predetermined tube voltage or tube current from a radiation generator 57 described later, the X-ray tube is set to a tube voltage or the like for a specified irradiation time. A corresponding dose of radiation is emitted.

  As described above, since the imaging room Ra is shielded by lead or the like, even if information such as the image data D is transmitted / received from the radiographic imaging apparatus 1 via the antenna apparatus 41 in the imaging room Ra, it is transmitted and received as it is. Can not. Therefore, as shown in FIG. 1, when the radiographic imaging apparatus 1 and the console 58 communicate wirelessly, a repeater (also referred to as a base station or a wireless access point) provided with a wireless antenna 53 that relays these communications. 54 is provided.

  As described above, the bucky device 51 and the repeater 54 are connected by a cable or the like. When the radiographic image capturing device 1 is loaded into the bucky device 51 and used, it is output from the radiographic image capturing device 1. The thinned data Dt and the like are transmitted to the console 58 in a wired manner via the bucky device 51, the repeater 54, and the like.

  A cradle 55 is connected to the repeater 54. As shown in FIG. 12, when the radiographic imaging device 1 brought into the radiographic room Ra is inserted and the connector 39 of the radiographic imaging device 1 and the connector 55a of the cradle 55 are connected, as described above, the radiation The cassette ID is notified from the image capturing apparatus 1 to the repeater 54 via the cradle 55. When the cassette ID of the radiation image capturing apparatus 1 is transmitted from the cradle 55, the relay unit 54 notifies the console 58 of the cassette ID.

  The cradle 55 is normally used for storing and charging the radiation image capturing apparatus 1 and the like, and the cradle 55 has a function such as charging in each of the following embodiments. Is also possible. Furthermore, although FIG. 12 shows the cradle 55 provided with two insertion ports for inserting the radiographic imaging device 1, the number of insertion ports may be one, or three or more.

  The cradle 55 may be installed in either the imaging room Ra or the front room Rb. When the cradle 55 is installed in the imaging room Ra, a position where the radiation irradiated from the radiation source 52 does not reach, that is, for example, the imaging room. Installed at the corner of Ra.

  On the other hand, instead of using the cradle 55 as described above, or as a detecting means for detecting the radiographic image capturing apparatus 1 brought into the imaging room Ra or the front room Rb and notifying the console 58 of the cassette ID, or as described above. As shown in FIG. 13, for example, a tag reader 62 may be provided near the door of the front chamber Rb. In FIG. 13, illustration of the HIS 60 and the RIS 61 (see FIG. 1) is omitted.

  In the case of such a configuration, a tag (not shown) such as a so-called RFID (Radio Frequency IDentification) tag is built in the radiographic imaging apparatus 1 in advance, and unique information such as a cassette ID of the radiographic imaging apparatus 1 is included in the tag. Remember me. When the radiographic image capturing apparatus 1 passes through the vicinity of the tag reader 62 and is brought into the imaging room Ra or the front chamber Rb, the tag reader 62 reads information such as a cassette ID from the tag of the radiographic image capturing apparatus 1, and the cassette It can be configured to notify the console 58 of the ID.

  In this way, if the tag reader 62 is used as the detection means, it is possible to detect both the carry-in of the radiographic image capturing apparatus 1 into the photographing room Ra and the take-out from the photographing room Ra, which is preferable. In this case, the tag reader 62 and the cradle 55 can be configured to double check at least whether the radiation image capturing apparatus 1 is brought into the photographing room Ra. When only the tag reader 62 is used as the detection means, the cradle 55 is used simply for charging the radiographic image capturing apparatus 1, for example.

  As shown in FIG. 1, the front chamber Rb is provided with a radiation generator 57 including an exposure switch 56 and the like for instructing the radiation source 52 to start radiation irradiation.

  In each embodiment, the console 58 is provided in the front chamber Rb, and is configured by a computer or the like in which a CPU, a ROM, a RAM, an input / output interface and the like (not shown) are connected to a bus. A predetermined program is stored in the ROM, and the console 58 reads out a necessary program, expands it in a work area of the RAM, and executes various processes according to the program.

  The console 58 may be provided outside the photographing room Ra, and can be provided outside the photographing room Ra or the front room Rb instead of being provided inside the front room Rb.

  The console 58 is provided with a display unit 58a composed of a CRT, an LCD, or the like, and other input means such as a keyboard or a mouse are connected thereto. The console 58 is connected to a storage means 59 composed of a hard disk or the like, and a HIS (Hospital Information System) 60 or RIS (Radiology Information) via a network N such as a LAN (Local Area Network). System) 61 is connected.

  Although not shown, the console 58 includes an external device such as another computer or an imager that records and outputs a radiation image on an image recording medium such as a film based on data output from the console 58. It is connected via a LAN or the like.

  As described above, when the radiographic imaging device 1 brought into the radiographing room Ra is inserted into the console 58 and the cassette ID of the radiographic imaging device 1 is transmitted via the cradle 55 or the repeater 54. The cassette ID is stored in the storage means 59, and it is recognized and managed that the radiation image capturing apparatus 1 having the cassette ID is brought into the imaging room Ra or the front room Rb.

  Further, as described above, when the console 58 receives a signal indicating that the radiographic imaging apparatus 1 has entered the radiographable mode together with the cassette ID, the console 58 corresponds to the cassette ID stored in the storage unit 59. If the information indicating the attached and stored mode is information indicating the shootable mode, the information is left as it is. If the information indicating the stored mode is information indicating the sleep mode, the cassette ID can be used for shooting. The information indicating the mode is newly overwritten and saved.

  Further, when a signal indicating that the sleep mode has been entered from the radiographic image capturing apparatus 1 is transmitted together with the cassette ID, the mode stored in association with the cassette ID stored in the storage unit 59 When the information indicating the sleep mode is information, the information indicating the sleep mode is left as it is. When the information indicating the stored mode is the information indicating the shootable mode, the information indicating the sleep mode is newly associated with the cassette ID. To overwrite.

  In this way, the console 58 recognizes and manages whether the radiographic image capturing apparatus 1 is currently in the image capture enable mode or the sleep mode.

  Further, as described above, when the cassette 58 and the Bucky ID of the radiographic image capturing apparatus 1 are transmitted from the bucky apparatus 51 to which the radiographic image capturing apparatus 1 is connected to the connector 51b, the console 58 stores the storage means 59. The cassette ID stored in is stored in association with the Bucky ID.

  When the connection between the radiographic image capturing apparatus 1 and the connector 51b is released, the association between the cassette ID and the Bucky ID of the radiographic image capturing apparatus 1 stored in the storage unit 59 is canceled, Only the cassette ID is stored.

  In this manner, when the radiographic imaging device 1 is used by being loaded into the bucky device 51, the console 58 is used to determine which radiographic imaging device 1 is loaded into which bucky device 51 or loaded. It is designed to recognize and manage it.

  On the other hand, the HIS 60 and RIS 61 shown in FIG. 1 can register imaging order information in which information necessary for performing predetermined radiographic imaging for individual patients is set in advance. Note that, instead of registering the imaging order information in the HIS 60 or the RIS 61, it is possible to register the imaging order information in advance on the console 58 and store it in the storage means 59, for example.

  As illustrated in FIG. 14, for example, the imaging order information includes “patient ID” P2, “patient name” P3, “sex” P4, “age” P5, “clinic department” P6, and imaging conditions as patient information. The “imaging region” P7, “imaging direction” P8, and the like, and further, “Bucky ID” is used as information on whether or not imaging is performed with the radiographic imaging device 1 loaded in the Bucky device 51. "P9" is provided, and when it is loaded in the bucky device 51, its bucky ID is described.

  In the example shown in FIG. 14, the Bucky IDs “001” and “002” represent the Standing imaging Bucky device 51A and the Standing imaging Bucky device 51B, respectively, and the Bucky ID “003” represents the radiation image capturing device. 1 is used in a single state without being loaded into the bucky device 51. Note that when the radiographic image capturing apparatus 1 is used in a single state without being attached to the bucky apparatus 51, the bucky ID “003” is used when the radiographic image capturing apparatus 1 is used in a single state. This is because it cannot be distinguished from forgetting to enter.

  Therefore, other display methods can be adopted as long as they indicate that the radiographic imaging apparatus 1 is used in a single state, and can be determined as appropriate. Note that, instead of the bucky ID, three types of icons representing standing bucky, saddle bucky, and single use may be prepared, and one icon may be displayed in association with each photographing order. is there. If comprised in this way, it will become easy to visually recognize which imaging device should be used before a radiographer etc. image | photographing, and it becomes difficult to make a mistake.

  Then, “shooting order ID” P1 is automatically assigned to each shooting order information in the order in which shooting orders are registered.

  The patient information and the imaging conditions to be written in the imaging order information are not limited to those described above, and include, for example, information such as the patient's date of birth, the number of medical examinations, the radiation dose, and whether the patient is fat or thin. It is also possible to configure as described above. Hereinafter, a case where a plurality of pieces of imaging order information are registered for one patient will be described.

  The console 58 obtains necessary radiographing order information from the HIS 60 and the RIS 61 by the operation of a radiographer or other radiographer. Instead of obtaining the shooting order information from the HIS 60 or RIS 61, the shooting order information is registered in advance on the console 58 and stored in, for example, the storage means 59, and the necessary shooting order information is obtained from the storage means 59. It is also possible to do.

  When obtaining necessary radiographing order information from the RIS 60, the HIS 61, or the storage means 59, for example, the photographer inputs the name of the patient to be photographed, the patient ID, etc. to the console 58, or the photographing request form brought by the patient. Are read by a barcode reader and input to the console 58, or when the shooting date is specified in the shooting order information, the shooting date is input to the console 58, etc. It is possible to obtain the necessary imaging order information from the HIS 60, the RIS 61, or the storage means 59 by this method.

  When the console 58 obtains the imaging order information, a list of each imaging order information is displayed on the display unit 58a of the console 58 as a selection screen H1, as shown in FIG.

  The selection screen H1 is provided with a shooting order information display field h11 for displaying a list of each shooting order information. On the left side of the shooting order information display field h11, shooting order information scheduled to be shot is selected. A selection button h12 is provided for each shooting order information. In addition, a determination button h13 and a return button h14 are provided below the shooting order information display field h11.

[Example of icons displayed on the console display]
For example, when the photographer clicks the selection button h12, selects four pieces of imaging order information related to the patient “A”, for example, and clicks the decision button h13, the console 58 is displayed on the display unit 58a in FIG. A screen H2 as shown in FIG. In other words, the console 58 displays the icons I1 to I4 corresponding to each selected shooting order information on the display unit 58a, for example, in ascending order of shooting order ID (see P1 in FIG. 15), that is, in the order of registration. It has become.

  Although the registration order is basic, for example, when there are imaging orders for both the left and right parts with respect to the limbs, etc., based on the condition that the imaging is from the left to the first, or from the right to the first, in order to prevent left-right confusion May be rearranged.

  FIG. 16 shows a case where the icons I1 to I4 are displayed side by side on the screen H2 from the left side in the left-right direction. However, the present invention is not limited to this. For example, the icons I1 to I4 are displayed in the vertical direction. It is also possible to arrange them so as to be arranged from the upper side, and the display method of the icons I1 to I4 is appropriately set.

  Further, the icons I1 to I4 are arranged in the registered order. In addition to this, for example, in each selected radiographing order information, a patient ID (see P3 in FIG. 15 or the like) or a medical treatment is different. When items with different departments (see P6) are included, the icons I corresponding to the imaging order information of the same patient or department can be displayed so as to be adjacent to each other regardless of the registration order. .

  Here, an example of the icon I displayed on the screen H2 will be described.

  As shown in FIG. 16, the icons I1 to I4 each have an imaging number such as “KM-0001”, an imaging region (P7) such as “abdominal front P → A”, an imaging direction (P8), The presence / absence of the use of the bucky device 51 such as “” and the type of the bucky device 51 to be used are displayed.

  Further, in the example of FIG. 16, the icon I1 corresponding to the shooting order information (see FIG. 15 and the like) of the shooting order ID “001” using the bucky device 51 for the supine position shooting has a display portion Ia in the icon I1. A horizontally long square is displayed on the icon I2 and I3 corresponding to the shooting order information of the shooting order IDs “002” and “003” using the standing-up shooting bucky device 51. A vertically long square is displayed in Ia.

  Further, in the icon I4 corresponding to the imaging order information of the imaging order ID “004” that does not use the bucky device 51, a figure in a perspective view of the radiographic imaging device 1 is displayed on the display portion Ia in the icon I1.

  Note that when the display portion Ia in the icon I displays the use of the standing-up photographing or the stand-up photographing bucky device 51 or the use of the radiographic image photographing device 1 alone, the above-mentioned As described above, measures such as a display that is easy to understand for radiologists and the like are taken as appropriate, rather than a square or perspective figure.

  When the console 58 displays the icons I1 to I4, referring to the Bucky ID associated with the cassette ID stored in the storage unit 59, the photographing using the Bucky device 51 as shown in FIG. The cassette ID of the radiographic imaging device 1 currently loaded in the bucky device 51, the size and resolution of the radiographic imaging device 1, etc. are displayed on the display portion Ib of the icon I of the order information.

  Further, for example, when changing to use a bucky device 51 different from the bucky device 51 set for each icon I1 to I4, or when the radiographic imaging device 1 wants to take an image without using the bucky device 51. In this case (or vice versa), for example, the cursor is moved to the display position Ia of “standing position” or “prone position” in the corresponding icon I on the screen H2, and a pop-up is displayed when the mouse is right-clicked. It is also possible to configure so as to select and change the item of not using the bucky device 51 or the bucky device 51 described in the window.

  Furthermore, when changing the radiographic imaging device 1 set for each icon I1 to I4, for example, the cursor is moved to the display portion Ib in the corresponding icon I on the screen H2, and the mouse is right-clicked. By doing so, for example, a selection screen H3 as shown in FIG. 17 is displayed, and the radiographic imaging device 1 to be changed is appropriately selected from the icons representing the various radiographic imaging devices 1 and changed. It is also possible to configure.

  For example, when changing any one of the radiographic imaging devices 1 set to the icons I1 to I4 to the CR cassette, for example, the same operation is performed to display the selection screen H3 as shown in FIG. For example, it may be configured to change by clicking on an icon displayed as “CR”. With this configuration, a radiographer or other radiographer can change the desired radiographing order information from the radiographic imaging system (FPD system) to the CR system in the anterior chamber Rb in which the console 58 is provided. It becomes possible.

  As described above, when the bucky device 51 to be used is changed, the bucky device 51 is not used or the bucky device 51 is used, or the radiographic imaging device 1 to be used is changed, the change is made. The displayed icons I1 to I4 are switched to the changed contents. Note that the gauge G representing the degree of progress of processing, which is displayed below the icons I1 to I4 in FIG. 16, will be described later.

[Example of icon focus transition]
Next, an example of how to display the icons I1 to I4 on the display unit 58a of the console 58 under the above configuration will be described. In the following, as the simplest case, a case will be described in which only one radiographic imaging device 1 is brought into the imaging room Ra.

  In the following, a case will be described in which the radiographic image capturing apparatus 1 is already loaded in the standing-up image capturing device 51A. Therefore, in this case, the icons I1 to I4 as shown in FIG. 18 are displayed on the screen H2 of the console 58. In this case, even when the mouse is right-clicked on the display portion Ib of “FPD” in the icon I, only the radiation image capturing apparatus 1 of “FPD-001” is displayed on the selection screen H3 shown in FIG. .

  The console 58 automatically selects one icon I from the icons I1 to I4 corresponding to each shooting order information displayed on the display unit 58a as described above, and selects the selected icon I for another. The icon I is displayed in a different manner. In the following, displaying an icon I in a different form from the other icons I is abbreviated as focusing on the icon I. Further, when the focused icon I is illustrated, the icon I is indicated by hatching.

  As a method of focusing the icon I, for example, when the icon I is basically displayed in a color close to the background color of the screen H2, such as blue or black, and a certain icon I is focused and displayed, Only the icon I can be configured to be displayed in red or yellow. In addition, the focused icon I is displayed in a shape different from that of the other icons I, the focused icon I is blinked, the display position of the focused icon I on the screen H2 is changed, or zooming is performed. It is also possible to configure the display so as to be up.

  When the console 58 automatically selects the icon I, in this example, the icon I is selected and focused according to the following criteria.

[Standard 1]
Without changing the current state of each radiation image capturing apparatus 1, such as the mode of the radiation imaging apparatus 1, the loading state with respect to the bucky device 51, the activation and arrangement state of each radiation source 52, and the position and orientation of the radiation source 52 A (see FIG. 1) The icon I corresponding to the imaging order information in which the imaging conditions that can perform imaging or can perform imaging with the least degree of change are designated is selected and focused.

  Therefore, if the photographer takes an image based on the imaging order information corresponding to the icon I focused by the console 58, the radiographic image capturing device 1 is loaded into the Bucky device 51 or the radiographic image captured in the Bucky device 51 is captured. It is possible to take an image without performing an operation of reloading the apparatus 1 into another Bucky device 51 or performing only a minimum operation, and an image can be taken quickly. There is.

  The details of the reference 1 are appropriately set depending on the configuration of the radiation image capturing system 50, the performance of each device, and the like. When the radiographic imaging device 1 or the radiographic imaging system 50 is configured as described above, for example, the corresponding icon I is automatically displayed according to the detailed criteria shown in [1-1] and [1-2] below. Selected.

[1-1] When the radiographic image capturing apparatus 1 is loaded in the bucky device 51, it corresponds to radiographing order information that specifies that radiography is performed in the state where the radiographic image capturing device 1 is loaded in the bucky device 51. The icon I to be selected is selected and displayed in focus.
[1-2] When the radiographic image capturing apparatus 1 is not loaded in the Bucky apparatus 51, the radiographing apparatus information includes radiographing order information that specifies that radiography is performed in a single state where the radiographic image capturing apparatus 1 is not loaded in the Bucky apparatus 51. The corresponding icon I is selected and displayed in focus.

  According to the above standard [1-1], for example, when the radiographic image capturing apparatus 1 is mounted on the standing-up imaging bucky device 51A, the radiation source 52A is directed toward the standing-up imaging bucky device 51A. Of course, the radiographic image capturing apparatus 1 is usually extracted from the standing position photographing bucky device 51A even when it is not facing the direction of the standing position photographing bucky device 51A. It is possible to reduce the load on the photographer by changing the irradiation direction of the radiation source 52 </ b> A with less change than when re-loading it to the bucky device 51 </ b> B. In addition, since the preparation of the radiation source is completed before inputting the start of imaging on the console 58 and actually moving into the imaging room, it is possible to finish imaging at an early stage.

  Further, according to the above standard [1-2], if the radiographic imaging device 1 is not loaded in the bucky device 51, the bucky device 51 is loaded rather than loading the radiographic imaging device 1 in the bucky device 51. When photographing in a single state not loaded, the amount of work of the photographer can be reduced by the amount that the radiation image photographing apparatus 1 is attached to and detached from the bucky device 51.

  Further, even in the case of the above-mentioned standard [1-2], when the photographer determines that the radiographing apparatus 1 is loaded into the Bucky apparatus 51 to perform the imaging first, According to the following criterion 3, an icon I different from the icon I selected by the console 58 can be selected and focused.

[Standard 2]
When the radiographic imaging device 1 is not brought into the radiographing room Ra, or when it is impossible to determine which icon I is focused according to the above-mentioned criteria (hereinafter, this state is abbreviated as default) The console 58 displays the icons I1 to I4 displayed in a predetermined order such as the registration order on the display unit 58a in the order of the icons I that have not yet been photographed. Is the earliest icon I (in the case of FIG. 16, FIG. 18, etc., the icon I1 displayed on the left side) is selected and focused.

[Standard 3]
The reason why the console 58 automatically selects and focuses the icon I is to recommend that the icon I be selected because of the above-described effect, and corresponds to the selected icon I and the focused icon I. It does not force the photographing based on the photographing order information to be performed.

  Therefore, when the photographer wants to perform photographing based on photographing order information other than the photographing order information corresponding to the focused icon I, the photographer clicks another icon I corresponding to the photographing order information for photographing. The icon I can be selected.

  When the photographer clicks and selects an icon I different from the focused icon I, the icon I selected by the photographer is focused, and the focus of the icon I automatically selected by the console 58 is focused. Canceled. That is, the icon I automatically selected by the console 58 is displayed in the same manner as the other icons I by returning to the display of the original state which is not focused.

  For example, when the radiographic imaging device 1 is loaded in the standing-up imaging bucky device 51A, the console 58 displays the icons I1 to I4 on the screen H2 as shown in FIG. The icon I2 or the icon I3 is selected according to the first criterion. Then, when only the icons I2 and I3 are viewed, the above-mentioned default criterion 2 is applied, so the icon I2 is selected. Therefore, on the screen H2 of the display unit 58a of the console 58, the icon I2 is selected and focused as shown in FIG.

  When the console 58 focuses and displays the selected icon I (icon I2 in the case of FIG. 19), the console 58 immediately determines each device used for the shooting based on the shooting order information corresponding to the icon I. It starts to the state of. That is, in the case shown in FIG. 19, if the radiation source 52A is not activated, the radiation source 52A is activated, and if it is not ready to irradiate the standing-up imaging device 51A, the radiation source 52A is placed at a predetermined position. To change the irradiation direction.

  If the method specified by the selected icon I is the FPD method, the console 58 transmits to the radiation generating apparatus 57 that the FPD method is selected, and the method specified by the selected icon I is the CR method. If there is, the fact that the CR system is used is transmitted to the radiation generator 57. In this way, the radiation dose irradiated from the radiation source 52 of the radiation generator 57 is switched so as to correspond to each of the FPD method and the CR method.

  When each apparatus is activated in this way, as described above, the radiographer loads the radiographic image capturing apparatus 1 not loaded in the bucky apparatus 51 into the bucky apparatus 51 or the radiographic image loaded in the bucky apparatus 51. The photographer can move into the photographing room Ra because the photographing device 1 can be photographed without performing the operation of reloading the photographing device 1 into the other bucky device 51 or by performing the minimal operation. It becomes possible to quickly take a picture later.

  On the other hand, a radiographer or other radiographer does not perform the above operation on the screen H2 of the display unit 58a of the console 58, for example, brings a new radiographic image radiographing apparatus 1 into the radiographing room Ra and loads it into the cradle 55. The console 58 is notified that a new radiographic imaging apparatus 1 has been brought in, and the selection switch 38 of the radiographic imaging apparatus 1 is pressed, or the new radiographic imaging apparatus 1 is loaded into the bucky device 51. There are cases like this.

  In such a case, since the cassette ID and the like are transmitted to the console 58, the console 58 can recognize that the above operation has been performed. When such an operation is performed, it can be determined that the photographer intends to perform imaging using the newly brought-in radiographic imaging device 1.

  Therefore, in such a case, when the cassette ID or the like is transmitted, the console 58 saves and registers the cassette ID or the like in the storage unit 59 and also focuses on the icon I or the like focused on the screen H2 of the display unit 58a. The display of the icon I is switched according to the newly transmitted information such as the cassette ID and based on the above-mentioned criteria.

  In the following embodiments, description will be made on the assumption that the focus transition of the icon I is performed as described above. For example, the icons I1 to I4 displayed on the screen H2 are displayed in the display order, that is, at the top. It is also possible to configure the focus transition in the order of the icons I1, I2, I3, and I4 in order from the icon I1, and the focus transition method is not limited to the above example.

  While the radiation source 52, the radiographic image capturing apparatus 1 and the like are activated based on the imaging order information corresponding to the focused icon I (including the changed focused icon I), radiographing or the like is performed. For example, the person guides the patient into the imaging room Ra (see FIG. 1) or takes a predetermined posture at a predetermined position.

  Then, the photographer moves to the front room Rb and operates the exposure switch 56 when the situation where the photographing can be performed is ready, so that radiation is emitted from the radiation source 52 and radiographic imaging is performed.

  When radiographic imaging is performed, as described above, the control unit 22 of the radiographic imaging device 1 reads the image data D from each radiation detection element 7 and stores it in the storage unit 23. Further, the control means 22 automatically thins out the image data D at a predetermined ratio based on the image data D read out from the radiation detection elements 7 and automatically creates the thinned data Dt for preview. The thinned data Dt with the cassette ID is transmitted to the console 58 via 41 or the Bucky device 51.

  Further, after transmitting the thinned data Dt to the console 58, the control unit 22 assigns a cassette ID to the image data D that is the basis for creating the thinned data Dt and automatically transmits it to the console 58. The image data D may be transmitted without creating the thinned data Dt, or the image data D may be transmitted when a transmission instruction is issued from the console 58 or the like. This is as described above.

  Further, the control means 22 calculates an offset correction value O based on the dark read value d read out in the dark reading process performed at a predetermined timing, and assigns a cassette ID to the calculated offset correction value O, so that the console 58 Automatically send to.

  The console 58 creates a preview image based on the thinned data Dt transmitted when the thinned data Dt and the like are transmitted from the radiation image capturing apparatus 1.

  Then, as shown in FIG. 20, the console 58 displays the created preview image p_pre instead of the icon I2 at the position where the focused icon I2 is displayed on the screen H2 of the display unit 58a. It is supposed to be displayed. A radiographer or other radiographer can see the preview image p_pre, confirm the quality of patient positioning at the time of radiographing, etc., and can prepare for reimaging as necessary.

  Further, the console 58 displays a preview image p_pre and a series as a diagnosis providing image such as gradation processing on the image data D (that is, raw data) displayed under the preview image p_pre (original icon I2). The first stage of the gauge G (the leftmost gauge in FIG. 20) representing the degree of progress of the image processing is colored and displayed.

  The console 58 performs various image processing such as offset correction, gain correction, and logarithmic conversion correction on the image data D based on the image data D and the offset correction value O transmitted from the radiation image capturing apparatus 1. Then, the final image processed radiographic image p is generated.

  At that time, although not shown, according to the degree of progress of the image processing on the image data D, an image in the middle of the image processing is appropriately displayed at the position where the preview image p_pre is displayed on the screen H2, and the processing progresses. The second stage of the gauge G representing the degree is colored and displayed to indicate that image processing is in progress.

  When the third stage of the gauge G (the rightmost gauge in FIG. 20) is colored, the preview image p_pre is overwritten with the radiation image p as shown in FIG. A radiographer or the like recognizes that the radiographic image p has been overwritten by this third stage of coloring, confirms whether the contrast is appropriate based on the image p, in other words, the appropriateness of the irradiation dose, and re-photographs as necessary. Make preparations. It should be noted that the gauge G representing the degree of progress of the process can be modified as appropriate, for example, by changing the length of the rod, and the gauge G can be configured not to be displayed.

  Also, as shown in FIG. 20, when the preview image p_pre is displayed on the screen H2, “OK” and “NG” buttons are displayed below the preview image p_pre. The photographer clicks the “OK” button when shooting is normal and re-shooting is not necessary, and the “NG” button is clicked when shooting is not normal and re-shooting is required. In this way, the photographer is confirmed.

  When the photographer views the preview image p_pre and determines that re-shooting is not necessary and clicks the “OK” button and inputs a signal indicating that the shooting is approved, the console 58 displays another icon I. The focus is displayed, but this process will be described later.

  When the photographer determines that re-imaging is necessary by looking at the preview image p_pre and the radiation image p and inputs a signal indicating that the imaging is not approved by clicking the “NG” button, the console 58 In addition to returning the preview image p_pre and the radiation image p to the original icon I2, the “OK” button and the “NG” button are also deleted from the screen H2, or the “OK” button and the “NG” button are clicked. I can't do it. The display of the gauge G is also restored.

  Then, the transmitted thinning data Dt and image data D are discarded, and the radiographic imaging apparatus 1 is instructed to discard the image data D and the like obtained by the radiographic imaging and stored in the storage unit 23. To do. This is because the image data D and the like obtained by the radiographic imaging are unnecessary.

  When the photographer clicks the “OK” button, the console 58 displays the preview image p_pre and the radiation image p without returning the display of the preview image p_pre and the radiation image p to the original icon I2. The display of the “OK” button or “NG” button is also erased from the screen H2, or the “OK” button or “NG” button cannot be clicked.

  The console 58 cannot select the icon I2 again even if the photographer moves the cursor on the preview image p_pre or the radiation image p and clicks, for example, as in the case of selecting the icon I. Like that.

  This is because there is no need to re-select a photograph that has already been performed normally (that is, a photograph that is determined not to require re-shooting), and has already been obtained by re-selecting a photograph that has already been performed normally. This is to prevent inconveniences such as discarding the existing image data D and the like. In some cases, it is necessary to perform radiographic imaging again based on the imaging order information, and by performing a special operation in case it becomes necessary to discard already obtained image data D or the like. It is also possible to configure so that image data D and the like already obtained for the imaging order information can be discarded. In this case, an appropriate operation method is set.

  Then, when the final radiographic image p is generated, as shown in FIG. 21, the generated radiographic image p is displayed on the screen H2 where the image being processed (that is, the preview image p_pre is displayed). And the third stage of the gauge G (the right gauge in FIG. 21) is colored and displayed, and each process up to the generation process of the radiation image p is completed. Indicates.

  The console 58 stores the generated radiographic image p in the storage unit 59 in association with the imaging order information corresponding to the original icon I2. Further, the image data D before image processing (that is, so-called raw data) can be stored in the storage unit 59 in association with the photographing order information.

  Further, when “OK” on the lower side of the preview image p_pre shown in FIG. 20 is clicked, the console 58 selects the next icon I again according to the above-mentioned criteria as shown in FIG. And focus on it.

  Specifically, in the case of the console 58 shown in FIG. 20, the radiographic imaging device 1 is loaded in the standing-up imaging bucky device 51A. In addition, it is not necessary to change the loading state of the radiographic imaging device 1 with respect to the bucky device 51, and the imaging order information that enables imaging without changing the activation state, position, orientation, etc. of each radiation source 52A from the current state. The corresponding icon I3 is selected and focused.

  As described above, in the radiographic image capturing system 50 according to the present embodiment, not the default icon I1, but the mode of each radiographic image capturing device 1, the loading state with respect to the bucky device 51, the activation state of each radiation source 52, and the radiation source 52A. The icon I2 corresponding to the shooting order information in which shooting conditions that can be shot without changing the current state of each, such as the position and orientation, are automatically selected and focused.

  In this case, since the imaging based on the imaging order information corresponding to the icon I2 has just been performed and the radiographic image capturing apparatus 1 is in the radiographable mode, it is necessary to transmit an awakening signal from the console 58 to the radiographic image capturing apparatus 1. Absent. In addition, the radiation source 52A is activated and is ready to irradiate the bucky device 51A for standing imaging. However, when the radiation dose to be irradiated changes, the tube is irradiated so as to irradiate that dose. Voltage etc. are changed.

  When radiographic image capturing is performed, thinning data Dt and the like are transmitted from the radiographic image capturing apparatus 1 to the console 58, and the console 58 performs a preview image p_pre based on the transmitted thinning data Dt and the like in the same manner as described above. Creation, display, generation and display of a radiation image p.

  The console 58 displays the preview image p_pre at the position of the original icon I3, and when the “OK” button is clicked, subsequently, the next icon I is again selected and focused according to each of the above criteria.

  In this case, the selectable icons I are the icon I1 and the icon I4. However, the console 58 selects and focuses the icon I1 in light of the reference 1 described above. The reason for selecting in this way is that when imaging based on imaging order information corresponding to the icon I4 is performed, the radiation source 52A must be stopped and the portable radiation source 52B must be activated. This is because when performing imaging based on the corresponding imaging order information, it is only necessary to change the position and irradiation direction of the activated radiation source 52A.

  Thus, if the icon I3 is selected in the above case, the loading state of each radiographic imaging device 1 with respect to the bucky device 51, the activation state of each radiation source 52, the position and orientation of the radiation source 52A, etc., respectively. The next shooting can be performed with the least change from the current state.

  Therefore, if imaging is performed based on the imaging order information corresponding to the icon I1 focused by the console 58, the photographer moves the radiographic imaging device 1 from the standing-up imaging device 51A to the standing-up imaging device 51B. Since it only needs to be reloaded, it is possible to perform shooting with a minimum of operations, and shooting can be performed quickly.

  As described above, when the method such as the focus transition of the icon I is used, the radiographic image capturing system 50 is easy to use for the photographer and the radiographic image capturing can be performed efficiently.

  In the following embodiments, as the focus transition of the icon I, for example, the icons I1 to I4 displayed on the screen H2 can be configured to perform focus transition in the display order. However, as described above, the method is not limited to the method such as the focus transition of the icon I described above.

  18 to 22, the case where only one radiographic image capturing apparatus 1 is brought into the imaging room Ra has been described. However, in the following embodiments, the present invention is not limited to this, and as illustrated in FIG. In addition, the present invention is also applied to a case where a plurality of radiographic imaging devices 1 are brought into the imaging room Ra.

[Description of Embodiments According to the Present Invention]
Next, a method of processing in each embodiment according to the present invention under the above configuration will be described.

[First Embodiment]
As described above, when the thinning data Dt is transmitted from the radiographic image capturing apparatus 1, the console 58 displays the preview image p_pre at the position of the icon I displayed on the display unit 58a as described above. However, in this embodiment, the console 58 has transmitted the thinned data Dt among the display means 51c (see FIG. 1) associated with each of the above-described bucky devices 51. The thinned data Dt is transmitted to the display means 51c associated with the bucky device 51 in which the radiation image capturing apparatus 1 is loaded, and the preview image p_pre based on the thinned data Dt is displayed on the display means 51c. Yes.

  For example, in the case shown in FIG. 20, the radiographic imaging device 1 that has transmitted the thinning data Dt is loaded in the standing-up imaging device 51 </ b> A. When the decimation data Dt is transmitted, the decimation data Dt is transmitted to the display means 51c associated with the standing-up imaging device 51A, and the preview image p_pre is displayed on the display means 51c.

  In this case, for example, a screen similar to the screen H2 displayed on the display unit 58a of the console 58 as shown in FIG. 20 can be configured to be displayed on the display means 51c. In this case, a screen similar to the screen H2 shown in FIG. 20 is displayed on the display means 51c, and for example, the preview image p_pre is displayed at the position of the icon I2.

  With this configuration, the photographer can confirm the preview image p_pre related to the photographing on the display unit 51c, and also the contents of the next photographing, that is, the bucky device 51 in which the radiographic image photographing device 1 is loaded. Whether the next imaging is to use the radiographic imaging apparatus 1 alone, or which part of the patient's body as the subject is to be imaged from which direction, etc. It becomes possible to confirm by looking at the display of the display means 51c.

  For example, as shown in FIG. 23, it is possible to display only the preview image p_pre without displaying the other icons I and the like on the display means 51c. With this configuration, the preview image p_pre can be displayed on the display unit 51c in a relatively large size, so that the photographer can easily see the preview image p_pre and accurately determine whether or not re-shooting is necessary. Is possible.

  Even in the case shown in FIG. 23, it is possible to display on the display means 51c the shooting conditions relating to the shooting, the contents of the next shooting, and the like. It is also possible to display the preview image p_pre in a display manner other than the display as shown in FIG. 20 or FIG. 23. How to display the preview image p_pre on the display means 51c Is appropriately determined.

  On the other hand, for example, as shown in FIGS. 20 and 23, when the preview image p_pre is displayed on the display unit 51c, an “OK” or “NG” button is also displayed on the display unit 51c. It is also possible to do.

  With this configuration, the photographer who viewed the preview image p_pre does not have to move to the console 58 in the front room and click the “OK” button or the “NG” button, and the display in the photographing room Ra can be avoided. It is possible to input a signal indicating that the shooting is approved by clicking the “OK” button on the means 51c, or to input a signal indicating that the shooting is not approved by clicking the “NG” button. Become.

  When the photographer clicks the “OK” button or the “NG” button on the display means 51c, it represents a signal indicating the contents, that is, a signal indicating that the shooting is approved or that the shooting is not approved. The signal is transmitted to the console 58 via the repeater 54, and the console 58 performs the same processing as when the “OK” button or the “NG” button is clicked on the display section 58a of the console 58 described above.

  Further, for example, as shown by an icon I4 in FIG. 20, the portable radiographic image capturing apparatus 1 may be used for imaging in a single state without being loaded into the Bucky apparatus 51. In this case, the thinning data Dt is transmitted in a wireless manner from the antenna device 41 (see FIG. 3 and the like) of the radiographic image capturing apparatus 1 to the wireless antenna 53 (see FIG. 1) of the repeater 54 and passes through the repeater 54. Sent to console 58.

  However, in such a case, since the radiographic imaging device 1 is not loaded in the bucky device 51, the console 58 displays the transmitted thinning data Dt on the display means 51 c associated with any of the bucky devices 51. I don't know if I can send it.

  Therefore, in this way, when the radiographic image capturing apparatus 1 is used in a single state without being loaded into the bucky apparatus 51 and imaging is performed, it is determined in advance to which display means 51c the thinning data Dt is transmitted. The thinned data Dt can be configured to be transmitted from the console 58 to the display means 51c associated with a predetermined specific bucky device 51 (for example, the bucky device 51B for lying position photography). is there.

  If comprised in this way, when imaging | photography is performed using the radiographic imaging apparatus 1 in the single state, since the preview image p_pre is displayed on the predetermined display means 51c, the photographer is determined in advance. It is possible to determine whether or not re-photographing is necessary by looking at the preview image p_pre displayed on the specific display means 51c.

  It should be noted that the specific display means 51c that transmits the thinned data Dt when imaging is performed using the radiographic image capturing apparatus 1 alone can be switched on the console 58 at an arbitrary timing. Is also possible. Further, as will be described in a fourth embodiment to be described later, when the relay 54 is configured to be able to set to which display means 51c the thinned data Dt is transmitted, the relay It is also possible to specify the display means 51c on the screen 54. This point will be described in a fourth embodiment.

  Next, the operation of the radiographic image capturing system 50 according to the present embodiment will be described.

  When a radiographer or other photographer loads the radiographic image capturing apparatus 1 in the Bucky apparatus 51 and performs radiographing, first, in the radiographing room Ra (see FIG. 1), the patient who is the subject and the radiographic image capturing apparatus 1 The positional relationship with the cassette holding unit 51a of the loaded bucky device 51, the irradiation direction and irradiation position of the radiation irradiated to the subject from the radiation source 52, and the like are adjusted. And it moves to the front chamber Rb and operates the exposure switch 56 provided in the radiation generator 57 to irradiate the subject with radiation from the radiation source 52.

  In the present embodiment, the photographer can move to the photographing room Ra immediately after the radiation irradiation is completed. And it goes to the place of the Bucky device 51 used for the photographing.

  The thinning data Dt is transmitted from the radiographic imaging apparatus 1 to the console 58 via the relay 54, and the thinning data Dt is transmitted from the console 58 to the display means 51c associated with the bucky device 51, and the display means 51c. Since it takes about several seconds to display the preview image p_pre on the upper side, while the photographer moves from the front room Rb to the photographing room Ra and goes to the Bucky device 51, the display means 51c is displayed. The preview image p_pre is already displayed.

  Therefore, the photographer who has moved to the photographing room Ra can see the preview image p_pre displayed on the display means 51c associated with the Bucky device 51 at the same time when the photographer arrives at the position of the Bucky device 51. It becomes possible to quickly determine whether or not re-shooting is necessary.

  In the case where the radiographic image capturing apparatus 1 is used in a single state without being mounted on the bucky apparatus 51, the photographer first takes a subject from the radiation source 52 in the imaging room Ra (see FIG. 1). The irradiation direction, irradiation position, etc. of the radiation applied to the patient are adjusted, and the position, etc., to which the radiation image capturing apparatus 1 is applied to the patient as the subject is adjusted. And it moves to the front chamber Rb and operates the exposure switch 56 provided in the radiation generator 57 to irradiate the subject with radiation from the radiation source 52.

  When a portable radiation source 52B (see FIG. 1) is used as the radiation source 52, the photographer adjusts the position and the like as described above, and then operates the portable radiation source 52B to emit radiation. Irradiate.

  In this case, the thinning data Dt is transmitted to the console 58 from the antenna device 41 of the radiographic imaging apparatus 1 via the relay 54 in a wireless manner, but the thinning data transmitted from the radiographic imaging apparatus 1 to the console 58 is also used. It takes only a few seconds for Dt to be transmitted from the console 58 to the display means 51c associated with the specific Bucky device 51 and to display the preview image p_pre on the display means 51c.

  Therefore, the photographer views the preview image p_pre displayed on the display means 51c associated with the specific bucky device 51 at the same time as or without arriving at the position of the specific bucky device 51. This makes it possible to quickly determine whether or not re-shooting is necessary.

  If it is determined that re-imaging is unnecessary, the photographer clicks the “OK” button, and promptly changes the patient's pose for the next imaging, or sets the radiographic imaging apparatus 1 to another one. It is possible to take necessary measures such as re-loading to the bucky device 51 and guiding the patient to the other bucky device 51.

  If it is determined that re-imaging is necessary, the photographer clicks the “NG” button, discards the thinned data Dt and image data D transmitted to the console 58, and promptly releases the radiation source 52. It is possible to perform re-imaging by taking necessary measures such as adjusting the position of the patient or adjusting the position of the patient with respect to the bucky device 51.

  As described above, according to the radiographic image capturing system 50 according to the present embodiment, the console remains in the front chamber Rb even after the photographer operates the exposure switch 56 to irradiate the radiation as in the conventional system. It is not necessary to wait until the preview image p_pre is displayed on the display unit 58a of 58, and the photographer immediately moves to the photographing room Ra after the irradiation of the radiation and is displayed on the display means 51c in the photographing room Ra. The displayed preview p_pre can be confirmed.

  This makes it possible for the photographer to quickly start preparing for the next shooting or to take necessary actions such as preparing for the re-shooting, so that the photographer will not feel uncomfortable or frustrated, It is possible to make the radiographic image capturing system 50 convenient for the photographer.

  In addition, since the photographer can take necessary actions such as immediately preparing for the next shooting or preparing for the re-shooting, as described above, for example, When imaging the same patient multiple times and imaging different parts of the patient's body, it is possible to perform multiple imaging smoothly. 50 is easy to use.

[Second Embodiment]
In the first embodiment, as described above, on the radiation image capturing apparatus 1 side, the control unit 22 thins out the thinned data Dt (see FIG. 9) obtained by thinning out the data from the read image data D at a predetermined rate. The case where it is configured to create and send to the console 58 has been described.

  However, the same applies to the third embodiment to be described later, but the radiographic image capturing apparatus 1 transmits all the read image data D to the console 58, and the console 58 uses the image data D at a predetermined rate. There is also a radiographic image capturing system configured to generate thinned data Dt by thinning data. In such a case, the present invention can be applied.

  That is, in this case, when the image data D is transmitted from the radiation image capturing apparatus 1, the console 58 creates thinned data Dt obtained by thinning data from the image data D at a predetermined rate, and the radiation image capturing apparatus 1 The thinned data Dt created is transmitted to the display means 51c associated with the loaded bucky device 51, and the preview image p_pre based on the thinned data Dt is displayed on the display means 51c.

  With such a configuration, even in the case of the present embodiment, the display unit of the console 58 remains in the front chamber Rb even after the photographer operates the exposure switch 56 to irradiate the radiation as in the conventional system. There is no need to wait until the preview image p_pre is displayed on 58a, and the photographer can immediately move to the photographing room Ra and confirm the preview p_pre displayed on the display means 51c after the end of radiation irradiation. It becomes possible.

  Then, the preview image p_pre is displayed on the display means 51c when the photographer who has moved to the photographing room Ra arrives at the place of the bucky device 51 used for the photographing or shortly thereafter.

  This makes it possible for the photographer to quickly start preparing for the next shooting or to take necessary actions such as preparing for the re-shooting, so that the photographer will not feel uncomfortable or frustrated, The same beneficial effects as in the case of the first embodiment, such as making the radiographic image capturing system 50 easy to use for the photographer, can be achieved.

[Third Embodiment]
In addition, some photographers such as radiologists want to start preparing for the next shooting as soon as the shooting is finished. For such a photographer, the preview image p_pre is associated with the Bucky device 51 used for the next photographing, not the display means 51c associated with the Bucky device 51 used for the current photographing. In some cases, it may be more convenient to display on the display means 51c.

  Therefore, in the present embodiment, a radiographic image capturing system 50 configured to be easy to use for such a photographer will be described.

  That is, in this embodiment, as described in the first embodiment, the console 58 performs focus transition of the icon I according to the above-described criteria on the screen H2 (see FIG. 22 and the like). ing. That is, the console 58 is configured to grasp the order of shooting performed using each of the bucky devices 51.

  Further, even when the focus transition of the icon I is not performed, for example, the icons I1 to I4 displayed on the screen H2 are displayed in the display order, that is, the icons I1, I2, I3, and I4 in order from the top icon I1. The console 58 is configured to make a focus transition, and the console 58 is configured to grasp the order of photographing performed using each of the bucky devices 51.

  Therefore, the console 58 uses the thinning data Dt transmitted from the radiation image capturing apparatus 1 or the thinning data Dt created by itself based on the image data D transmitted from the radiation image capturing apparatus 1 as the first, As described in the second embodiment, instead of transmitting to the display means 51c associated with the bucky device 51 in which the radiographic imaging device 1 that performed the imaging is loaded, the next imaging in the above order. Is transmitted to the display means 51c associated with the bucky device 51 to be used with the radiation image capturing apparatus 1 loaded, and the preview means p_pre based on the thinned data Dt is displayed on the display means 51c. Is possible.

  In this case, as shown in FIG. 22, for example, when the shooting corresponding to the icon I3 is performed after the shooting corresponding to the icon I2, the shooting corresponding to the icon I3 is the shooting corresponding to the icon I2. The same standing-up shooting bucky device 51A is used. Therefore, the console 58 transmits the thinned data Dt obtained by the photographing corresponding to the icon I2 to the display means 51c associated with the standing photographing Bucky device 51A used in the photographing corresponding to the icon I3.

  However, for example, when shooting corresponding to the icon I1 is performed next to shooting corresponding to the icon I3, the bucky device 51 for lying position shooting is used for shooting corresponding to the icon I1. Therefore, the console 58 captures the thinned data Dt obtained by the photographing corresponding to the icon I3, not the standing-up shooting device 51A used in the photographing corresponding to the icon I3, but the photographing corresponding to the next icon I1. Is transmitted to the display means 51c associated with the bucky device 51B for the supine position photographing used in the above.

  Further, for example, when imaging corresponding to the icon I4 is performed next to imaging corresponding to the icon I3, the radiographic image capturing apparatus 1 is not loaded in the Bucky apparatus 51 and is alone in the imaging corresponding to the icon I4. In this state, shooting is performed. For this reason, the console 58 uses the thinned data Dt obtained by the imaging corresponding to the icon I3 as the single radiographic imaging device 1 instead of the standing-up imaging device 51A used in the imaging corresponding to the icon I3. When used in a state, the thinned data Dt is transmitted to a specific bucky device 51 set to transmit, for example, the display means 51c associated with the bucky device 51B for lying position photography.

  Therefore, when the photographer who has finished irradiating the radiation and returned to the photographing room Ra goes to the Bucky device 51 used for the next photographing in order to prepare for the next photographing, it is used for the next photographing. The preview image p_pre is displayed on the display means 51c associated with the bucky device 51.

  Further, when the next radiographing is performed using the radiographic imaging device 1 alone, the photographer who has returned to the radiographing room Ra prepares for the next radiographing while preparing for the next radiographing. If the display means 51c associated with the bucky device 51 (for example, the bucky device 51B for lying position photography) is seen, the preview image p_pre is displayed on the display means 51c.

  Therefore, if configured as described above, even in the case of this embodiment, the console 58 remains in the front chamber Rb even after the photographer operates the exposure switch 56 to irradiate radiation as in the conventional system. There is no need to wait until the preview image p_pre is displayed on the display unit 58a, and the photographer immediately moves to the imaging room Ra and confirms the preview p_pre displayed on the display means 51c after the radiation irradiation ends. It becomes possible to do.

  Then, when a photographer who wants to start preparation for the next shooting immediately after the shooting is finished, returns to the shooting room Ra to start preparation for the next shooting, the bucky device 51 used in the next shooting. If the display means 51c associated with the specific bucky device 51 is seen, a preview image p_pre is displayed on the display means 51c.

  This makes it possible for the photographer to quickly start preparing for the next shooting or to take necessary actions such as preparing for the re-shooting, so that the photographer will not feel uncomfortable or frustrated, The same beneficial effects as those in the first and second embodiments, such as making the radiographic image capturing system 50 easy to use for the photographer, can be obtained.

  Note that the methods according to the first and second embodiments described above, that is, the console 58 transmits the thinned data Dt to the display means 51c associated with the Bucky device 51 used in the photographing to display the preview image p_pre. The method and the method according to the third embodiment, that is, the method in which the console 58 transmits the thinned data Dt to the display means 51c associated with the Bucky device 51 used in the next shooting of the shooting to display the preview image p_pre. Can be configured to be switched on the console 58, for example.

  According to this configuration, the photographer can select and specify which method is to be used for shooting, according to the situation, the method according to the first or second embodiment or the method according to the third embodiment. This enables the radiographing system 50 to be more convenient for the photographer.

[Fourth Embodiment]
As described above, if a photographer such as a radiographer can further select the method of performing imaging according to the situation and improve the usability of the radiographic imaging system 50, As shown in the first to third embodiments, a series of shootings (that is, a series of shootings selected on the selection screen H1 (see FIG. 15)) are all performed by any of the methods shown in each embodiment. For example, the photographer is configured to be able to determine the display means 51c that transmits the thinned-out data Dt at each time of photographing, or at an arbitrary timing based on his / her own judgment. Is also possible.

  In this case, for example, the repeater 54 (see FIG. 1) provided in the radiographing room Ra is provided with an input means, so that the repeater 54 receives the thinned data Dt transmitted from the radiographic image capturing apparatus 1. To which display means 51c can be set, and when the thinned data Dt is transmitted from the radiographic imaging apparatus 1, the relay 54 sends the thinned data Dt to the set display means 51c. It is possible to configure so that the preview image p_pre based on the thinned data Dt is displayed on the display unit 51c.

  In this case, the repeater 54 may be configured to transmit the thinned data Dt also to the console 58, but the thinned data Dt need not necessarily be transmitted to the console 58. When the repeater 54 is configured not to transmit the thinned data Dt to the console 58, the radiographic image capturing apparatus 1 transmits all the image data D via the repeater 54 after the thinned data Dt is transmitted. It is configured to transmit to the console 58.

  When configured as described above, a radiographer or other radiographer loads the radiographic imaging device 1 into the bucky device 51 in the radiographing room Ra or the positional relationship between the radiographic imaging device 1, the patient, and the radiation source 52. After moving to the front chamber Rb to operate the exposure switch 56 after preparing the image by adjusting etc., the relay device 54 is operated to display the preview image p_pre on any display means 51c. Whether to display, that is, to which display means 51c the thinned data Dt transmitted from the radiation image capturing apparatus 1 is set.

  Note that when the setting of the repeater 54 is already set to transmit the thinned data Dt to the display means 51c that wants to display the preview image p_pre, it is not necessary to make a new setting.

  And it moves to the front chamber Rb and operates the exposure switch 56 to irradiate the subject with radiation from the radiation source 52. Also in the present embodiment, the photographer can move to the photographing room Ra immediately after the radiation irradiation is completed.

  Then, when the photographer goes to the display means 51c set in the repeater 54 so as to display the preview image p_pre, the display means from which the thinning data Dt is transmitted from the radiographic image capturing apparatus 1 via the repeater 54. The preview image p_pre has already been displayed on 51c. Therefore, the photographer who has moved to the shooting room Ra can immediately see the preview image p_pre displayed on the display unit 51c, and can quickly determine whether or not re-shooting is necessary.

  Therefore, if configured as described above, the photographer still operates in the exposure switch 56 and irradiates the radiation as in the conventional system, and remains in the front chamber Rb and is previewed on the display 58a of the console 58. There is no need to wait until the image p_pre is displayed, and the photographer immediately moves to the photographing room Ra after the radiation irradiation and confirms the preview p_pre displayed on the display means 51c immediately. Is possible.

  This makes it possible for the photographer to quickly start preparing for the next shooting or to take necessary actions such as preparing for the re-shooting, so that the photographer will not feel uncomfortable or frustrated, It is possible to achieve the same beneficial effects as in the above-described embodiments, such as the radiographic image capturing system 50 being easy to use for the photographer.

  In addition, since the photographer can display the preview image p_pre on the display means 51c set by the relay 54, the photographer can select a display means 51c that is convenient for the photographer for each photographing or arbitrarily. In this respect, the radiographic image capturing system 50 is easy to use for the photographer.

  In each of the above embodiments, at the time when the last shooting of the series of shootings selected on the selection screen H1 (see FIG. 15) is completed, the photographer needs to return to the shooting room Ra immediately for the next shooting. In some cases, it may be sufficient if the preview image p_pre can be confirmed on the display 58a of the console 58 in the front room Rb.

  Therefore, in each of the above embodiments, the console 58 is based on the thinned data Dt transmitted from the radiographic image capturing apparatus 1 or the transmitted image data D after the final imaging of the selected series of imaging is completed. The thinned data Dt created in step S3 is not transmitted from the console 58 to any display means 51c in the imaging room Ra, and the preview image p_pre can be displayed only on the display unit 58a of the console 58. It is.

  In this case, that is, even after the final shooting of a series of shots is completed, the thinned data Dt is transmitted from the console 58 to any display means 51c in the shooting room Ra, and a preview image is displayed on the display means 51c. It is also possible to configure to display p_pre.

  In addition, it goes without saying that the present invention is not limited to the above-described embodiments and modifications, and can be changed as appropriate.
