Description

  The present invention relates to a radiographic imaging system.

  For the purpose of disease diagnosis and the like, radiographic images taken using radiation typified by X-ray images are widely used. Radiation images for medical use have traditionally been taken using screen film, but CR (Computed Radiography) cassettes using stimulable phosphor sheets have been developed to digitize radiographic images. 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 image capturing 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 addition, in such portable radiographic imaging apparatuses, radiographic imaging apparatuses that have built-in batteries and that transmit and receive signals and data by exchanging radio waves via communication means equipped with an antenna or the like have been developed ( For example, see Patent Document 4). Hereinafter, the portable radiographic imaging device is referred to as an FPD cassette.

  In addition, as the FPD cassette, a so-called direct type FPD cassette that generates electric charges by a detection element in accordance with the dose of radiation such as irradiated X-rays and converts it into an electric signal, or the irradiated radiation is visible with a scintillator or the like. There are various so-called indirect type FPD cassettes that convert to electromagnetic signals by generating electric charges in photoelectric conversion elements such as photodiodes after being converted to electromagnetic waves of other wavelengths such as light and then converted according to the energy of the irradiated electromagnetic waves Has been developed.

  In the present invention, a detection element in a direct type FPD cassette and a photoelectric conversion element in an indirect type FPD cassette are collectively referred to as a radiation detection element.

  By the way, since the FPD cassette has portability as described above, for example, as described in Patent Document 5, in a situation where there are a plurality of radiographing rooms in a hospital or the like, a radiographer or other radiographer uses an FPD cassette. It has a feature that the cassette can be carried to each imaging room and used for radiographic imaging.

  However, in such a situation, if it is not possible to accurately grasp in which imaging room the FPD cassette was used, for example, image data transmitted from the FPD cassette may be Data for other FPD cassettes is erroneously applied as gain correction data for correcting a gain value, defect correction data for specifying the position of a radiation detecting element having a defect, etc., and based on image data There is a risk that the radiation image generated in this way becomes an abnormal image.

  Also, the imaging conditions and the like for imaging using the FPD cassette are designated, and the imaging order information necessary for managing the radiographic images obtained by the imaging in association with each other is obtained with another FPD cassette. There is also a risk that the captured image data and the radiation image based on the image data are associated with each other by mistake.

  Therefore, in Patent Document 5, for example, each FPD cassette is provided with an RFID (Radio Frequency IDentification) tag, and a tag reader is provided in a photographing room or an anterior room (also referred to as an operation room or the like), and a photographer brings in the FPD cassette. In this case, the RFID tag of the FPD cassette is read with a tag reader. Alternatively, the photographer who brought the FPD cassette into the photographing room inserts the FPD cassette into the cradle.

  Then, information such as the cassette ID of the FPD cassette read by the tag reader and the cassette ID of the FPD cassette output via the cradle is notified to each console via the network. For example, the photographer can determine which FPD cassette is in a room and display a map showing the location of each FPD cassette in response to the photographer's request. An invention of a radiographic imaging system capable of recognizing whether there is a problem is disclosed.

Japanese Patent No. 3639750 JP 2006-058124 A JP-A-6-342099 JP-A-7-140255 International Publication No. 2008/111355 Pamphlet

  However, for example, when it is configured to detect the FPD cassette brought into the photographing room with a tag reader, it is not only necessary to provide a tag reader in the photographing room or the front room, but an RFID tag or the like is also provided in the FPD cassette. Is required. In addition, some RFID tags can transmit information to the tag reader by putting information on the reflected wave of the radio wave from the tag reader without supplying power to the tag, but the communicable distance is as short as several centimeters, as described above. It is not practical to use the FPD cassette for bringing it into the shooting room.

  Moreover, in order to extend the communicable distance, power is eventually supplied to the RFID tag and radio waves must be blown from the RFID tag side to the tag reader. In that case, the power of the FPD cassette must be turned on. If radio waves cannot be emitted from the RFID tag and the FPD cassette is brought in with the FPD cassette turned off, it is impossible to detect the FPD cassette brought into the photographing room. Further, if the power supply of the FPD cassette is always turned on, the battery built in the FPD cassette is exhausted, which is not realistic.

  On the other hand, an existing cradle in a photographing room or the like is usually used for storing or charging an FPD cassette. As described above, the cradle is used for registering an FPD cassette brought into the photographing room. The cradle needs to be modified and replaced. In addition, it is necessary to connect to an external device such as a console or a management device by connecting wiring to the cradle and connecting to a network. However, it is expensive to modify or replace the cradle or connect the wiring.

  For example, when there are a plurality of radiographing rooms, a radiographer or other radiographer once brings an FPD cassette into one radiographing room, inserts it into a cradle, and then registers the FPD cassette. Despite being taken out of the shooting room and brought into another shooting room, if you forgot to insert it into the cradle and register it, the console, etc. recognized that it was in the shooting room before the FPD cassette was taken out It will remain.

  For this reason, various inconveniences occur, such as the console controlling the FPD cassette that no longer exists in the imaging room, or the photographer mistaking the FPD cassette to perform imaging. In the worst case, a radiological image generated based on image data obtained by imaging related to a patient is mistaken for an image of another patient, and a doctor who has viewed the image has a lesion that should originally exist in the image. There is a risk of misdiagnosis such as finding a lesion or finding a lesion that is not supposed to exist.

  The present invention has been made in view of the above problems, and in which of the plurality of shooting rooms the FPD cassette exists without providing a registration tag reader or cradle in the shooting room. An object of the present invention is to provide a radiographic imaging system capable of accurately recognizing and controlling the image.

In order to solve the above-described problem, the radiographic imaging system of the present invention includes:
A bucky device that can be loaded with an FPD cassette;
A radiation source of a radiation generator for irradiating the FPD cassette with radiation through a subject;
A plurality of shooting rooms comprising:
The FPD cassette provided with communication means, which can be brought into the radiographing room and reads out information carried on the radiation irradiated from the radiation source through the subject as image data;
A console capable of communicating with the FPD cassette and capable of controlling the FPD cassette;
With
When the FPD cassette is loaded into the Bucky device, the FPD cassette notifies the console of its own identification information, or when the FPD cassette is loaded, the Bucky device reads out the identification information of the FPD cassette. Notify the console,
When the console acquires the identification information of the FPD cassette from the FPD cassette loaded in the Bucky device or the Bucky device loaded with the FPD cassette, the FPD cassette is provided in the shooting room including the Bucky device. Recognizing the existence, the FPD cassette is a control target.

  According to the radiographic imaging system of the system of the present invention, when the FPD cassette is loaded into the Bucky device provided in the photographing room, the FPD cassette is loaded from the Bucky device or the FPD cassette loaded into the Bucky device. Identification information is notified to the console. On the other hand, when the FPD cassette is brought into the photographing room, it is often loaded into a bucky device for standing position photographing or lying position photographing and used for photographing.

  Therefore, as in the present invention, if it is configured to confirm that the identification information of the FPD cassette is notified from the Bucky device in a certain shooting room, it is possible to accurately grasp that the FPD cassette exists in the shooting room. be able to. Therefore, the console can accurately control the FPD cassette after accurately recognizing that the FPD cassette exists in the photographing room including the bucky device.

  For this reason, it is possible to accurately prevent image data and radiographic images obtained by performing imaging using the FPD cassette for the patient in the imaging room from those of other patients. In addition, since it becomes possible to accurately recognize in which shooting room the FPD cassette is located using the existing Bucky device in the shooting room, a new registration is made in the shooting room for the registration of the FPD cassette. There is no need to install a tag reader or modify the cradle for registration.

The image data D and the like are transferred to the console 58 via a cable via a cable (see FIG. 11).

  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. In this way, the substrate 4 portion of the sensor panel SP of the FPD cassette 1 is formed. In FIG. 7, illustration of the electronic component 32 and the like is omitted.

  Here, the circuit configuration of the FPD cassette 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 radiation is applied to the FPD cassette 1 through a subject during radiographic imaging, the scintillator 3 converts the radiation into electromagnetic waves of other wavelengths, and the converted electromagnetic waves are directly below the radiation detection 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.

  In this way, the FPD cassette 1 reads out information carried on the radiation irradiated from the radiation source 52 of the radiation generator 57 (described later) through a subject (not shown) as image data D.

  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 scan driving unit 15 and the readout circuit 17 of the FPD cassette 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 for supplying power to each functional part of the FPD cassette 1. Further, the antenna device 41 and the connector 39 (not shown in FIG. 8) are connected to the control means 22.

  The control unit 22 controls the scanning drive unit 15 and the readout circuit 17 to read out the image data D from each radiation detection element 7 and each radiation detection for removing the charge remaining in each radiation detection element 7. Various functions are provided for each functional unit of the FPD cassette 1 such as resetting the element 7 or setting and varying the bias voltage applied to each radiation detection element 7 from the bias power supply 14 by controlling the bias power supply 14. It comes to perform control.

  In addition, when the control unit 22 performs the reading process of the image data D and the like from each radiation detection element 7, the control unit 22 stores the read image data D and the like in the storage unit 23 as described above. Then, the control means 22 transmits information such as each image data D read from each radiation detection element 7 to the console 58.

  In the present embodiment, as will be described later, the FPD cassette 1 has a size compatible with the CR cassette, and can be used by being installed in a later-described Bucky device 51 in the facility.

  Further, as will be described later, when the FPD cassette 1 is loaded in the bucky device 51, the FPD cassette 1 is supplied with power from the bucky device 51, but in a single state not loaded in the bucky device 51, the battery 24 (See FIG. 8), 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).

  In addition, when the radiographic imaging, the reading process of the image data D, and the like are not performed, if the power is supplied to each function unit, the battery 24 is consumed, and thus the control unit 22 of the FPD cassette 1 is configured as described above. The power can be supplied to each functional unit to perform radiographic imaging, that is, the radiographable mode in which the radiographing can be performed, and the power is supplied only to the functional unit necessary for suppressing power consumption. The power supply mode for each functional unit can be switched at least between the sleep mode in which the supply of power to the radiation detection element is stopped and the radiation image cannot be captured.

  Further, when the power supply mode is switched, the control unit 22 transmits a signal indicating that the photographing mode is set or a signal indicating that the sleep mode is set to the console 58 together with its own cassette ID. It is like that.

  Next, the imaging room Ra and other devices in the radiographic imaging system 50 will be described.

  As shown in FIG. 1 and FIG. 9, each photographing room Ra is provided with a bucky device 51 including a cassette holding portion (also referred to as a cassette holder) 51 a into which the FPD cassette 1 can be loaded.

  FIG. 9 shows a case in which a standing-up shooting bucky device 51A and a standing-up shooting bucky device 51B are installed as the bucky device 51 in the shooting room Ra. The present invention is also applied to a case where only the bucky device 51A for the camera or only the bucky device 51B for the position photographing is provided.

  In the present embodiment, the bucky device 51 is configured so that a conventional CR cassette can be loaded into the cassette holding part 51a and used, and the existing bucky device installed in the photographing room Ra for the CR cassette is used. Is used.

  Therefore, the FPD cassette 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.

  In order to enable the use of the JIS standard size CR cassette in the Bucky device 51, the FPD cassette 1 also has dimensions conforming to the JIS standard in the cassette for screen films to which the CR cassette conforms. It is formed with.

  In the case where an existing bucky device for a screen / film cassette or a CR cassette is not used, it is not necessary to form the FPD cassette 1 with the above dimensions, and the FPD cassette 1 can be formed in any size or shape. Is possible. However, in that case, it is necessary to newly install a bucky device capable of loading the FPD cassette 1 having an arbitrarily set shape as the bucky device 51 in the photographing room Ra.

  In this embodiment, as shown in FIG. 10, before loading the FPD cassette 1 into the bucky device 51, the connector 51b provided at the tip of the cable 51c extending from the bucky device 51 is connected to the connector 39 of the FPD cassette 1. In this state, the FPD cassette 1 is loaded into the cassette holding part 51a of the bucky device 51.

  For example, as shown in FIG. 11, a connector 51b that is automatically connected to the connector 39 (see FIG. 2) of the loaded FPD cassette 1 is provided inside the cassette holding portion 51a of the bucky device 51. It is also possible to do. In this case, the connector 51b is provided in the same manner in the bucky device 51B for standing position shooting as well as the bucky device 51A for standing position shooting shown in FIG.

  When the connector 51b and the connector 39 of the FPD cassette 1 are connected, the bucky device 51 reads the cassette ID that is the identification information from the FPD cassette 1, and the cassette ID of the FPD cassette 1 and the bucky ID that is its own identification information. Are associated with each other and notified to the console 58.

  In this embodiment, the case where the Bucky device 51 is configured to read the identification information of the FPD cassette 1 in this way will be described. However, the Bucky device 51 loads, for example, an FPD cassette into the cassette holding unit 51a. The FPD cassette 1 simply holds the FPD cassette 1, and when connected to the connector 51b of the bucky device 51, the FPD cassette 1 itself includes its own identification information, that is, the cassette ID together with the bucky ID in the cable 51c (FIG. 9). It is also possible to configure to notify the console 58 via (see FIG. 10).

  In addition, when the FPD cassette 1 is loaded and used in the cassette holding unit 51a, the bucky device 51 receives image data D output from the FPD cassette 1 through the connector 39, etc. Are transmitted to the console 58 via the repeater 54.

  Further, the connector 51 b of the bucky device 51 and the connector 39 of the FPD cassette 1 are connected to supply power from the bucky device 51 to the FPD cassette 1. Therefore, when the connectors 39 and 51b are connected to each other, the control means 22 of the FPD cassette 1 stops the supply of power from the battery 24 (see FIG. 8) to each functional unit, and the bucky device via the connector 39 The power supplied from 51 is switched to be supplied to each functional unit.

  Further, when the FPD cassette 1 is loaded and used in the bucky device 51 and the FPD cassette 1 receives an instruction from the console 58 to change the power supply mode of the FPD cassette 1 to the sleep mode, the FPD cassette 1 The power supplied from the bucky device 51 may be supplied to the battery 24 so that the battery 24 is charged.

  As shown in FIGS. 1 and 9, 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 (see FIG. 9) is arranged suspended from the ceiling of the imaging room Ra, for example, and is based on an instruction from the console 58 during imaging. It is activated and moved to a predetermined position by a moving means (not shown). Then, as shown in FIG. 9, by changing the irradiation direction of the radiation, the FPD cassette 1 loaded in the standing position shooting bucky device 51A or the standing position shooting bucky device 51B is irradiated with radiation. Can be done.

  Further, as shown in FIG. 9, a portable radiation source 52B that is not associated with the standing-up photographing or the standing-up photographing Bucky devices 51A and 51B may be provided in the photographing room Ra.

  The FPD cassette 1 is applied to a part of a patient's body as a subject in a single state (that is, not loaded in the bucky device 51), or a table or a bed (not shown) of a bucky device 51B for taking a lying position and the patient's body. In the case where the FPD cassette 1 is used in this manner, radiation can be emitted from the portable radiation source 52B at an appropriate distance and direction.

  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.

  Since the imaging room Ra is shielded with lead or the like so that radiation does not leak outside the imaging room, communication between each apparatus in the imaging room Ra and each apparatus outside the imaging room Ra is performed in the imaging room Ra. A repeater 54 having a wireless antenna 53 for relaying is provided.

  As shown in FIG. 9, the repeater 54 is connected to the bucky device 51 by the cable 51 c and the like as described above, and a console 58 described later outside the imaging room Ra, the management device S and the like via the console 58, It is connected.

  In the present embodiment, a cradle 55 for storing the FPD cassette 1 brought into the photographing room Ra is provided in the photographing room Ra. In the present embodiment, the cradle 55 is the FPD cassette 1. Is inserted, the battery 24 (see FIG. 8) of the FPD cassette 1 is charged. 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, the position where the radiation emitted from the radiation source 52 does not reach, that is, for example, imaging. It is installed at the corner of the room Ra.

  On the other hand, as shown in FIG. 9, the front chamber Rb is provided with a radiation generator 57 having an exposure switch 56 and the like operated by the photographer to instruct the radiation source 52 to start radiation irradiation. It has been.

  The radiation generating device 57 supplies a predetermined tube voltage, tube current, or the like to the radiation source 52 based on an instruction from the console 58, moves the radiation source 52 to a predetermined position, The radiation source 52 is activated by changing the irradiation direction or the like.

  A console 58 is provided in the front chamber Rb. The console 58 may be provided outside the front chamber Rb. In the present embodiment, as shown in FIG. 1, the console 58 is provided so as to correspond to each photographing room Ra one by one, but the console 58 necessarily corresponds to each photographing room Ra one-to-one. For example, a plurality of shooting rooms Ra and one or a plurality of consoles 58 may be connected via a network or the like.

  The console 58 is provided with a display unit 58a made up of a CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), or the like, and is connected to input means (not shown) such as a keyboard and a mouse. The console 58 is connected to a storage means 59 composed of a hard disk or the like, and the storage means 59 stores image data D transmitted from the FPD cassette 1.

  Further, the console 58 recognizes that the FPD cassette 1 is loaded in the bucky device 1 and recognizes that the FPD cassette 1 exists in the photographing room Ra, and controls the FPD cassette 1. This point will be described later.

  The management device S (see FIG. 1) is connected to each console 58 via a network N, and a specific FPD cassette 1 exists in a specific shooting room Ra from each console 58 (or a specific shooting room). When it is notified that Ra is installed in a specific Bucky device 51, which FPD cassette 1 is present in which imaging room Ra is recognized based on that information.

  Note that when this information is configured to communicate with each other between the consoles 58, the management device S is not necessarily provided.

  Next, processing in the console 58 will be described, and the operation of the radiation image capturing system 50 according to the present embodiment will be described.

  As described above, the console 58 is connected to the cassette 51 of the FPD cassette 1 from the FPD cassette 51 in the photographing room Ra that has read the cassette ID from the FPD cassette 1 connected to the connector 51b, or from the FPD cassette 1 through the connector 51b. When the ID and the Bucky ID are notified, the Bucky ID is stored in association with the cassette ID stored in the storage unit 59.

  When the connection between the FPD cassette 1 and the connector 51b of the bucky device 51 is released, the association between the cassette ID of the FPD cassette 1 stored in the storage unit 59 and the bucky ID is released, Only the cassette ID is stored.

  In this way, in the present embodiment, the console 58 recognizes and manages that the FPD cassette 1 is present in the photographing room Ra including the Bucky device 51 (for example, in the photographing room Ra1). ing. The console 58 is configured to control the FPD cassette 1.

  Further, in this embodiment, when the console 58 acquires the cassette ID of the FPD cassette 1 and puts it under its own management in this way, for example, the FPD cassette 1 previously has a Bucky device in another shooting room Ra. 51, when the FPD cassette 1 is already under the management of another console 58, the other console 58 is notified to cancel the management of the FPD cassette 1. Yes.

  Then, the other console 58 (that is, the console 58 associated with the other shooting room Ra in the present embodiment) deletes the cassette ID of the FPD cassette 1 from the storage unit 59 and removes the FPD cassette 1. Excluded from management.

  As described above, when the console 58 recognizes that the FPD cassette 1 exists in the corresponding photographing room Ra, the console 58 transmits the information to the management device S. It is also possible to configure so that S is performed.

  That is, when the management apparatus S receives the above information from the console 58, the management apparatus S manages the information itself and refers to the management status of the other consoles 58, and manages other consoles that are managing the FPD cassette 1. If there is 58, it is possible to notify the other console 58 to cancel the management of the FPD cassette 1.

  Further, as described above, when the console 58 receives a signal indicating that the camera is in the photographing enabled mode from the FPD cassette 1 together with the cassette ID, the console 58 is associated with the cassette ID stored in the storage unit 59. If the information indicating the power supply mode of the FPD cassette 1 stored in this way is information indicating the shootable mode, the information is left as it is, and if the information indicating the sleep mode is information indicating the shootable mode in the cassette ID Are newly overwritten and saved.

  When a signal indicating that the sleep mode has been entered is transmitted from the FPD cassette 1 together with the cassette ID, the FPD cassette stored in association with the cassette ID stored in the storage unit 59 is stored. If the information representing the power supply mode mode of 1 is information representing the sleep mode, the information is left as it is. If the information representing the stored mode is information representing the imageable mode, the sleep mode is represented in the cassette ID. The information is newly associated and saved.

  In this way, the console 58 recognizes and manages whether the FPD cassette 1 is currently in the power supply mode of the photographing enabled mode or the sleep mode. When the power supply mode is in the sleep mode when the FPD cassette 1 is loaded in the bucky device 51, the console 58 performs control so as to shift to the photographing enabled mode, for example. The cassette 1 is controlled.

  On the other hand, a photographer such as a radiographer has loaded the FPD cassette 1 into the bucky device 51 (for example, the bucky device 51B for lying position photography) in the photographing room Ra. It is considered that the FPD cassette 1 loaded in the camera is used for shooting.

  Therefore, in the present embodiment, as described above, the console 58 is connected to the FPD cassette 51 in the photographing room Ra or the FPD cassette 1 loaded in the Bucky device 51 via the cable 51c or a relay (see FIG. 9). When the cassette ID and the bucky ID of the cassette 1 are notified, the FPD cassette 1 loaded in the bucky device 51 (for example, the bucky device 51B for lying position imaging) is sent to the radiation generating device 57. The radiation source 52 is instructed to be activated so that radiation can be emitted.

  When the radiation generator 57 receives an instruction from the console 58, the radiation generator 57 supplies a predetermined tube voltage, tube current, or the like to the radiation source 52, or emits radiation to the bucky device 51B for supine photography, for example. The radiation source 52 is activated by moving the source 52 to a predetermined position or changing the irradiation direction of the radiation source 52.

  With this configuration, the radiation source 52 can be quickly activated without waiting for the photographer's instruction, and the photographer only finely adjusts the position, irradiation direction, and the like of the radiation source 52. Therefore, the radiation image capturing system 50 is convenient for the photographer.

  On the other hand, when the console 58 is notified of the cassette ID and the bucky ID from the bucky device 51 in the photographing room Ra or the FPD cassette 1 loaded in the bucky device 51 as described above, on the display unit 58a, for example, A screen H1 as shown in FIG. 12 is displayed.

  As shown in FIG. 12, the screen H1 includes icons I () corresponding to the bucky device 51 provided in the photographing room Ra, that is, for example, the bucky device 51A for standing shooting and the bucky device 51B for standing shooting. 51A) and I (51B) are displayed. Further, the screen H1 is an FPD cassette 1 that has been loaded in the Bucky device 51 of the shooting room Ra and recognized to exist in the shooting room Ra in the previous shooting, and has already been extracted from the Bucky device 51. An icon I (1) corresponding to the selected FPD cassette 1 is also displayed.

  Then, when a photographer such as a radiographer brings the FPD cassette 1 into the photographing room Ra and loads it into the bucky device 51B for lying position photographing, for example, as shown in FIG. 12, the bucky device 51B for lying position photographing. The photographer who viewed the screen H1 by displaying the icon I (51B) corresponding to the image H1, for example, by displaying it with a solid line and coloring it with a specific color such as blue or red, for example, causes the FPD cassette 1 to It can be confirmed that it is loaded in the shooting Bucky device 51B.

  In the present embodiment, the cassette ID of the loaded FPD cassette 1 (ie, “FPD−”) is displayed in the vicinity of the icon I (51B) corresponding to, for example, the bucky device 51B for lying position photography loaded with the FPD cassette 1. 003 ") and information such as resolution are displayed.

  In the state shown in FIG. 12, for example, another photographer takes out the FPD cassette 1 with the cassette ID “FPD-001” from the photographing room Ra (for example, the photographing room Ra1) and brings it into the photographing room Ra2, for example. When the FPD cassette 1 is connected to the connector 51b of the bucky device 51 in the photographing room Ra2, as described above, from the console 58 associated with the photographing room Ra2, to the console 58 associated with the photographing room Ra1, A notification requesting to cancel the management of the FPD cassette 1 is transmitted.

  Therefore, the console 58 associated with the imaging room Ra1 deletes the cassette ID “FPD-001” from the storage unit 59 and cancels the management of the FPD cassette 1. Therefore, the screen H1 of the display unit 58a of the console 58 associated with the imaging room Ra1 corresponds to the FPD cassette 1 with the cassette ID “FPD-001” as shown in FIG. 13 from the state shown in FIG. Switch to a state where icon I (1) is no longer displayed.

  On the other hand, when the FPD cassette 1 with the cassette ID “FPD-003” is pulled out from the bucky device 51B for lying position photographing in the state shown in FIG. 12, the connection with the connector 51b of the bucky device 51B is released. Since the signal indicating that the connection between the FPD cassette 1 and the connector 51b of the Bucky device 51 is released is transmitted from the Bucky device 51 or the FPD cassette 1, the console 58 sends the storage means 59 to the storage means 59 as described above. The association between the stored cassette ID of the FPD cassette 1 and the bucky ID is canceled, and only the cassette ID is stored.

  Then, the display on the screen H1 of the display unit 58a is switched to a state as shown in FIG. 14, and corresponds to the bucky device 51B for lying position photography in which the FPD cassette 1 is extracted and the FPD cassette 1 is not loaded. In the present embodiment, the icon I (51B) is displayed in the same manner as the icon I (51A) corresponding to the stand-up shooting bucky device 51A in which the FPD cassette 1 is not loaded. The display is switched to display only the line.

  In addition, the console 58 newly displays an icon I (1) corresponding to the extracted FPD cassette 1. This is because the FPD cassette 1 brought into the photographing room Ra is not normally taken out of the photographing room Ra1 when not in use, but is inserted into the cradle 55 (see FIG. 9), for example, so that the inside of the photographing room Ra1. It is because it is stored in.

  Further, as described above, the FPD cassette 1 is applied to the body part of the patient who is the subject in a single state where the FPD cassette 1 is not loaded, or the table or the bed (not shown) of the bucky device 51B for lying position photography Or can be used for imaging by, for example, irradiating radiation from a portable radiation source 52B (see FIG. 9).

  In this case, the image data D and the like are transmitted from the FPD cassette 1 that has been photographed in a single state to the console 58 via the antenna device 41 and the wireless antenna 53 of the repeater 54. In this way, the FPD cassette 1 can be used alone in the photographing room Ra.

  Then, as described above, once the FPD cassette 1 is loaded into the bucky device 51 and the console 58 recognizes that the FPD cassette 1 is present in the photographing room Ra, the FPD cassette 1 is thereafter When the camera is extracted from the bucky device 51 and used alone, the console 58 maintains a state in which it is recognized that the FPD cassette 1 exists in the imaging room Ra.

  Therefore, for example, when a radiographer or other photographer is planning to perform both radiography using the Bucky device 51 and radiography using the FPD cassette 1 in a single state for a single patient. Starting from shooting using the Bucky device 51 in the shooting room Ra, once the console 58 recognizes that the FPD cassette 1 is present in the shooting room Ra, the FPD cassette 1 is in the other room. As long as the FPD cassette 1 is not transported to the imaging room Ra, the console 58 maintains the state in which the FPD cassette 1 is recognized in the imaging room Ra even if the FPD cassette 1 is not loaded in the bucky device 51 again. To do.

  Therefore, even if the FPD cassette 1 that has been recognized to exist in the imaging room Ra is subsequently extracted from the bucky device 51 and used for imaging in a single state, the console 58 is capable of imaging the FPD cassette 1. It is possible to accurately control the FPD cassette 1 while accurately recognizing that it exists in the room Ra, and to reliably perform photographing.

  On the other hand, for example, in the state shown in FIG. 14, a radiographer or the like, this time, for example, to load the FPD cassette 1 with the cassette ID “FPD-002” into the standing-up imaging device 51A. When the connector 51b of the bucky device 51A is connected to the connector 39 of the FPD cassette 1 (see FIGS. 10 and 11), the cassette ID and the bucky ID are notified to the console 58 from the bucky device 51A and the FPD cassette 1.

  For this reason, the console 58 recognizes that the FPD cassette 1 with the cassette ID “FPD-002” is loaded in the standing-up photographing bucky device 51A in the photographing room Ra, and stores the cassette ID in the storage means 59. The management device S is notified that the FPD cassette 1 exists in the photographing room Ra.

  For example, if the power supply mode of the FPD cassette 1 is in the sleep mode, the mode is changed to the radiographable mode, and the radiation generator 57 is irradiated with radiation from the radiation source 52 to the standing-up radiographing device 51A. Start to irradiate.

  Further, as shown in FIG. 15, the console 58 switches so as not to display the icon I corresponding to the FPD cassette 1 of the cassette ID “FPD-002” displayed on the screen H1 of the display unit 58a. Further, the icon I (51A) corresponding to the standing position shooting Bucky device 51A is displayed with a solid line, colored with a specific color such as blue or red, and in the vicinity of the icon I (51A). In addition, information such as the cassette ID (ie, “FPD-002”) and resolution of the loaded FPD cassette 1 is displayed.

  Hereinafter, other processes such as a generation process of the radiation image p based on the image data D in the console 58 will be described.

  The console 58 obtains necessary information such as radiographing order information from a HIS or RIS (not shown) connected to the network N by the operation of a radiographer or other radiographer.

  The imaging order information is set by specifying at least an imaging region and imaging conditions. Specifically, as illustrated in FIG. 16, the imaging order information includes “patient ID” P2, “patient name” P3, “sex” P4, “age” P5, “clinic department” P6 as patient information, And “imaging part” P7, “imaging direction” P8 as an imaging condition, “bucket ID” P9 indicating the bucky device 51 to be used, “cassette ID” P10 of the cassette to be used, and the like. . Then, “shooting order ID” P1 is automatically assigned to each shooting order information in the order in which shooting orders are registered.

  When acquiring the shooting order information, the console 58 displays a list of each shooting order information on the display unit as a selection screen H2, as shown in FIG. In the present embodiment, a shooting order information display field h11, a selection button h12, a determination button h13, and a return button h14 are displayed on the selection screen H2.

  For example, when the photographer clicks the selection button h12 to select each piece of shooting order information and clicks the decision button h13, the console 58 displays a screen H3 as shown in FIG. 18 on the display unit. .

  As shown in FIG. 18, each icon I corresponding to each shooting order information is displayed on the screen H <b> 3, and a preview image p_pre displayed at the position of the icon I as described later is displayed below each icon I. An “OK” button that is clicked when the radiographer determines that the re-imaging is unnecessary, or determines that the radiographic image p displayed at the position of the icon I is normal and determines the radiographic image p, An “NG” button that is clicked when re-imaging is necessary or image processing for the radiation image p is performed again is displayed.

  Further, by clicking the “+” button or the “−” button of each item on the display Ia for setting the irradiation condition displayed on the right side of the screen H3, the tube voltage of the radiation source 52 of the radiation generating device 57 is displayed. The irradiation conditions such as the tube current and the irradiation time can be changed and set.

  In the present embodiment, each of the icons I1 to I4 is displayed so that any one icon I (icon I2 in the case of FIG. 18) is conspicuously displayed. Shooting based on the corresponding shooting order information is performed. When the photographer wants to perform photographing based on different photographing order information, the focus can be changed by clicking on another icon I corresponding to the photographing order information. .

  On the left side of the screen H3, the imaging part designated by the imaging order information corresponding to the icon I displayed in focus is displayed on the human body model Ib that is shown so that the photographer can understand at a glance. .

  On the other hand, when radiographic imaging based on radiographing order information corresponding to the icon I displayed in focus is performed, the thinned data Dt created from the image data D of each radiation detection element 7 is transmitted from the FPD cassette 1. Accordingly, as shown in FIG. 19, the console 58 displays a preview image based on the thinned data Dt that has been transmitted at the position of the focused original icon I2.

  Note that the preview image p_pre can be enlarged and displayed on the screen H3 so that the photographer can easily see the preview image p_pre. Thereafter, when image data D is transmitted from the FPD cassette 1, the console 58 associates the image data D with the imaging order information corresponding to the icon I.

  If the photographer who has viewed the preview image p_pre does not click the “NG” button while displaying the preview image p_pre for a predetermined time, the console 58 displays an icon I to be displayed in focus as shown in FIG. , For example, is transferred to the icon I3, and the generation processing of the radiation image p based on the image data D and the like transmitted from the FPD cassette 1 by imaging corresponding to the original icon I2 is started.

  When the photographer who has viewed the preview image p_pre clicks the “NG” button during the predetermined time, the association between the image data D and the photographing execution result with respect to the photographing order information is canceled, and the thinned data Dt and image data D are deleted. Further, the generation process of the radiation image p based on the image data D or the like is not performed.

  The console 58 performs processing such as offset correction, gain correction, defective pixel correction, and gradation processing according to the imaging region on the image data D. In addition, since there is a case where shooting is performed with a grid attached to the FPD cassette 1 at the time of shooting, filtering processing for removing moire by the grid is further performed.

  When shooting using a grid, moire may occur in the image data D due to the relationship between the grid pitch and the pixel size of the FPD cassette 1. As a countermeasure against this moire, the occurrence of moire can be avoided if the grid to be used is appropriately selected as described in, for example, Japanese Patent Application Laid-Open No. 2000-316126. Further, as described in Japanese Patent Laid-Open No. 8-88765, the image is once taken using a familiar grid, and the moire component included in the image data D is removed by filtering in the next step. It is also known.

In the case of the FPD cassette 1, since it is used in a plurality of radiographing rooms R as described in the present embodiment or used in round-trip destinations as described in the embodiments described later, it is possible to limit the grid types to be used. It's not a good idea. That is, it is preferable to use the grid that was used when the CR cassette was used for photographing. In addition, it is possible to store the grid pitch information used for each shooting in association with the read image every time shooting is performed.
Unlike the case of a dedicated radiographic imaging device, in the case of the FPD cassette 1, in order to associate grid pitch information, a large-scale modification of existing imaging equipment is required, and radiographers and the like in each imaging This is not realistic because the number of operations increases.

  Accordingly, the grid to be used is not limited, and several types of moire removal filters corresponding to the grid pitch that can be used are prepared in advance, and all the filters prepared in advance are sequentially applied to the image data D. A method of obtaining a radiation image p without moire by applying is preferable for the FPD cassette 1.

  When generating the radiation image p, the console 58 displays it at the position of the original icon I2, as shown in FIG. Then, when the photographer who has seen the radiographic image p determines that the generated radiographic image p is normal and clicks an “OK” button, the radiographic image p is confirmed and the radiographic image p is used as imaging order information. Associate.

  As described above, the console 58 performs other processing such as generation processing of the radiation image p based on the image data D.

  As described above, according to the radiographic image capturing system 50 according to the present embodiment, when the FPD cassette 1 is loaded into the bucky device 51 provided in the photographing room Ra, the bucky device 51 or the bucky device 51 is loaded. The FPD cassette 1 is configured to notify the console 58 of identification information of the FPD cassette 1.

  Therefore, the console 58 acquires the identification information of the FPD cassette 1 from the bucky device 51 provided in the photographing room Ra, so that the FPD cassette 1 exists in the photographing room Ra including the bucky device 51. Can be accurately recognized, and the FPD cassette 1 existing in the photographing room Ra can be accurately controlled.

  When the FPD cassette 1 is brought into the photographing room Ra, the FPD cassette 1 is often used for photographing by being loaded in the standing-up photographing bucky device 51A or the lying-up photographing bucky device 51B. Therefore, as in the present invention, if it is configured to confirm that the identification information of the FPD cassette 1 is notified from the bucky device 51 in a certain shooting room Ra, the FPD cassette 1 exists in the shooting room Ra. Can be accurately grasped.

  For this reason, the image data D and the radiographic image p obtained by performing imaging using the FPD cassette 1 existing in the imaging room Ra are accurately acquired on the console 58 associated with the imaging room Ra. It is possible to accurately prevent the image data D and the radiation image p related to a patient from being mistaken for those of other patients.

  In addition, since it is possible to accurately recognize in which shooting room Ra the FPD cassette 1 exists by using the existing Bucky device 51 in the shooting room Ra, a new one is used for registration of the FPD cassette 1. There is no need to provide a tag reader for registration in the photographing room Ra, or to modify the cradle 55 for use in registration.

  Needless to say, the present invention is not limited to the above-described embodiment, and can be changed as appropriate.
