Description

  The present invention relates to a radiographic imaging system, and more particularly to a radiographic imaging system including a radiographing room for radiographic imaging and a console for image processing image data obtained by radiographic imaging.

  Conventionally, for the purpose of disease diagnosis and the like, a radiographic image taken using radiation, represented by an X-ray image, has been widely used. Conventionally, such medical radiographic images have been taken using a screen film, but in recent years, digitization of radiographic images has been realized. For example, a stimulable phosphor layer forms radiation transmitted through a subject. After being stored in the photostimulable phosphor sheet, the photostimulable phosphor sheet is scanned with laser light, and thereby the photostimulated light emitted from the photostimulable phosphor sheet is photoelectrically converted to image data. CR (Computed Radiography) devices for obtaining the above are widely used (see, for example, Patent Documents 1 and 2).

  Recently, as a means for obtaining a radiographic image, a radiographic imaging apparatus that detects irradiated radiation and acquires it as digital image data has been developed. This type of radiographic imaging apparatus is known as an FPD (Flat Panel Detector). Conventionally, it has been formed integrally with a support base (see, for example, Patent Documents 3 and 4), but recently, a portable radiographic imaging device in which a radiation detection element and the like are housed in a housing has been developed (for example, a patent). References 5 and 6).

  As a radiographic imaging device, a so-called direct type radiographic imaging device that generates a charge by a detection element in accordance with a dose of irradiated radiation such as X-rays and converts it into an electrical signal, or a scintillator that radiates irradiated radiation So-called indirect radiation image that is converted into an electric signal by generating electric charge with a photoelectric conversion element such as a photodiode according to the energy of the converted electromagnetic wave after being converted into electromagnetic wave of other wavelengths such as visible light Various 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.

  At present, in radiographic imaging systems installed in hospitals and clinics, radiographic imaging devices are being introduced into radiographing rooms where CR devices are already installed. And radiographic imaging devices are being mixed.

  In Patent Document 7, as described above, in a situation where different types of devices such as CR devices and radiographic imaging devices coexist, an image with a constant finish can be obtained using either the CR device or the radiographic imaging device. There has been proposed a radiographic imaging system that can be obtained and is controlled so as to be easy to use for an operator such as a radiographer.

  By the way, radiographic imaging is performed, and whether or not the subject is appropriately captured in the radiographic image, that is, whether or not the subject is captured on the radiographic image, and the subject is captured at an appropriate position on the radiographic image. The operator, such as a radiographer, determines whether or not the image is actually taken.

  However, in the radiographic imaging system described in Patent Document 7, since the captured image is displayed on the display screen of the console installed outside the imaging room, the operator goes out of the imaging room one by one and goes to the installation location of the console. Thus, it is inconvenient for the operator to check the image. In addition, for example, a portable radiographic image capturing apparatus may be provided with a display unit such as a monitor, and the captured image may be displayed on the display unit for confirmation. When the photographing device is loaded into the Bucky device, the monitor is often not visible with the Bucky device, and the usability is not necessarily good. Furthermore, it is difficult to provide a monitor or the like with a CR cassette.

  Therefore, in Patent Document 3, although it is a case of a radiographic imaging apparatus integrated with a support base, a display unit is provided on a support base for standing imaging or supine imaging and transmitted from the radiographic imaging apparatus. There is described a radiographic imaging system configured to display the image data displayed on the display units so that an operator can check in the imaging room.

  However, in the case of the radiographic imaging system described in Patent Document 3, when an integrated radiographic imaging apparatus integrated with a support base is newly installed in the imaging room, a radiographic image with a display unit is provided. Personnel related to facilities such as hospitals do not feel much resistance to installing the imaging device, but if a CR device or radiographic imaging device is already installed in the imaging room, the existing CR device or radiographic image Installation of an additional display unit, for example, by newly laying a cable in a photographing apparatus or the like, has a problem of cost and the like, and feels resistance.

  However, as described above, the operator has to go to the console installed outside the radiographing room for each radiographic imaging and check the captured image. Since it becomes inconvenient, it is desired that this inconvenience is solved in the radiographic imaging system.

  The present invention has been made in view of the above points, and even when a CR device and a radiographic imaging device are mixed, a radiographic image that is easy to use for an operator such as a radiographer and can be introduced at a low cost. An object is to provide a photographing system.

Or when the thinning data is transmitted from the radiographic imaging device, the thinning data is transferred to the display device,
The display device displays a preview image on a screen based on the thinned data transferred from the console.

Moreover, the radiographic imaging system of the present invention is

The display device displays a preview image on a screen based on the thinned data transferred from the console.

  According to the radiographic imaging system of the system as in the present invention, the system can be configured only by installing a display device in the radiographing room with respect to an existing system in which radiographic imaging apparatuses and CR apparatuses are mixed. Therefore, the system can be easily constructed, and the system can be introduced at a low cost.

  When radiographic imaging is performed, image data and preview thinning data are automatically transmitted from the radiographic imaging device to the console, and image data is automatically transmitted from the CR device, and the console transmits Thinning data is automatically created based on the image data that has been provided. The thinned data is automatically transferred from the console to the display device, and a preview image is displayed on the screen based on the data.

Therefore, since it is possible to determine whether or not re-shooting is necessary, it is possible to quickly start the next shooting, which is very convenient for the operator. In addition, when the X-ray irradiation switch is operated, it takes a very short time to leave the patient alone in the imaging room, and the patient can be sufficiently cared for.

A cushioning material 36 is provided 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. In the present embodiment, the scintillator 3 is, for example, a phosphor whose main component is converted into an electromagnetic wave having a wavelength of 300 to 800 nm when receiving radiation, that is, an electromagnetic wave centered on visible light and output. .

  In the present embodiment, the substrate 4 is made of a glass substrate. As shown in FIG. 8, a plurality of scanning lines 5 and a plurality of signal lines are provided on a surface 4 a of the substrate 4 facing the scintillator 3. 6 are arranged so as to cross each other. 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.

  Thus, the entire region r in which a plurality of radiation detection elements 7 arranged in a two-dimensional manner are provided in each small region r partitioned by the scanning line 5 and the signal line 6, that is, shown by a one-dot chain line in FIG. The region is a detection unit P.

  In the present embodiment, a photodiode is used as the radiation detection element 7, but other than this, for example, a phototransistor or the like can also be used. As shown in FIG. 9 which is an enlarged view of FIG. 8, each radiation detection element 7 is connected to the source electrode 8s of the 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.

  In the present embodiment, as shown in FIG. 9, the bias lines 9 are respectively connected to the plurality of radiation detection elements 7 arranged in a row, and as shown in FIG. 8, each bias line 9 is connected to the substrate 4. Are bound to one connection 10 at a position outside the detection portion P.

  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. 10, a COF (Chip On Film) 12 in which a chip such as an IC 12a is incorporated in each input / output terminal 11 is an anisotropic conductive adhesive film (Anisotropic Conductive Film) or anisotropic conductive paste (Anisotropic paste). It is connected via an anisotropic conductive adhesive material 13 such as Conductive Paste).

  The COF 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. 10, 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 supply 14 applies a bias voltage (reverse bias voltage in this embodiment) 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 a source electrode 8s (denoted as S in FIG. 11) of the TFT 8, and a gate electrode 8g of each TFT 8 (denoted as G in FIG. 11). 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. 11) 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, in radiographic imaging, radiation is applied to the radiographic imaging apparatus 1 through a subject, and the scintillator 3 converts the radiation into electromagnetic waves of other wavelengths and irradiates the radiation detection element 7 directly therebelow. Then, electric charges (electric signals) are generated according to the dose of radiation (the amount of electromagnetic waves) irradiated by the radiation detection element 7.

  In the process of reading charges from each radiation detection element 7, the TFT 8 in which an on-voltage is applied to the gate electrode 8 g from the gate driver 15 b of the scanning drive unit 15 through the lines L 1 to Lx of the scanning line 5 is turned on. Electric charges are emitted from the radiation detection element 7 to the signal 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 logarithmically compressed (log-compressed), then converted into digital image data D by the A / D converter 20, output to the storage means 23 and sequentially stored. It has become so.

  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 means 22 controls the operation of each member of the radiographic image capturing apparatus 1. Further, the reset process of each radiation detection element 7, the readout process of charges from each radiation detection element 7, and the same process as the readout process after leaving the radiation imaging apparatus 1 in a state in which no radiation is irradiated to calculate the offset correction value. Each process such as a dark reading process for reading out the dark charge accumulated in each radiation detecting element 7 is performed.

  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, and although not shown in FIG. 11, the above-described power switch 37, selection switch 38, connector 39, etc. (see FIG. 5) are connected. Has been.

  When the selection switch 38 is pressed by an operator such as a radiologist, the control means 22 transmits a selection signal indicating that it has been selected to the console C via the antenna device 41.

  Further, when radiographic imaging is performed, the control unit 22 performs a readout process of reading out charges (image data D) from each radiation detection element 7 as described above. Further, in the present embodiment, the control means 22 thins out the image data D at a predetermined ratio based on the image data D read from each radiation detection element 7 and stored in the storage means 23, and the thinned data for preview. Dt is created.

  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 means 23, the thinned data Dt is immediately created. When the thinned data Dt is created, the antenna is immediately created. The thinned data Dt is transmitted to the console C via the device 41. This thinning data Dt is transmitted every time radiographic images are taken.

  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.

  In addition, when the radiographic imaging is completed alone or in series, the control unit 22 performs so-called dark reading processing in order to obtain data for offset correction among the image processing for the image data D obtained by radiographic imaging. Is supposed to do.

  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. The dark charges and the like accumulated therein are read out as a so-called dark read value d and stored in the storage means 23.

  As described above, the control unit 22 transmits the thinned data Dt created from the image data D to the console C immediately after the radiographing is completed, but the image data D and the dark read value d are stored for each radiographing. It is automatically transmitted every time it is finished, or it is put together at the time when an operation is performed by the operator on the radiation image capturing apparatus 1 after a series of radiation image capturing ends or when a transmission request is issued from the console C. It is supposed to be sent.

  Note that the transmission of the image data D and the dark reading value d to the console C is performed at an appropriate timing in consideration of the storage capacity of the storage unit 23 of the radiographic image capturing apparatus 1 and a series of radiographic image capturing intervals. Is called. Further, the radiographic imaging apparatus 1 itself can make a determination without waiting for an operator's operation on the radiographic imaging apparatus 1 or a transmission request from the console C.

  By the way, in this embodiment, it is assumed that the radiographic imaging device 1 is loaded into a screen / film cassette or a CR cassette's bucky device 51, and the radiographic imaging device 1 has a JIS standard size (that is, a CR cassette). A conventional JIS standard size for a cassette for a screen film (corresponding international standard is IEC 60406.). The size is 14 inches × 17 inches (half cut size). 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.

  However, when a screen / film cassette or a CR cassette cassette is not used, it is not necessary to form the radiographic imaging apparatus 1 with the above dimensions, and the radiographic imaging apparatus 1 is formed in an arbitrary size and shape. be able to. At that time, as the cassette holding portion 51a (see FIG. 12) of the bucky device 51, a shape in which the radiation image capturing device 1 can be loaded is installed.

  Next, the configuration of the imaging room R in the radiographic image capturing system 100 shown in FIG. 1 and the like will be described in detail.

  The imaging room R is a room in which radiation imaging is performed by irradiating a subject (part of the patient's imaging target) that is a part of the patient's body to irradiate the subject with radiation as shown in FIG. The radiation generator 53 and the like of the radiation irradiation apparatus are arranged so as to prevent leakage of radiation to the outside of the radiography room, the so-called radiographing room Ra, and the operation console 59 of the radiation irradiation apparatus operated by an operator such as a radiographer. Is disposed in the front chamber (also referred to as an operation chamber or the like) Rb.

  Note that FIG. 12 shows a case where one console C is connected to one shooting room R. As described above, this is the case when the configuration of the shooting room R is described. The case where R and the console C are connected to 1: 1 is illustrated together, and the present invention is not limited to this case.

  In the present embodiment, the imaging room Ra is provided with a bucky device 51 into which the radiation image capturing device 1 can be loaded, a CR device 52, and a radiation generating device 53.

  In FIG. 12 and the like, the case where the bucky device 51 is used for shooting in the supine position and the CR device 52 is used for shooting in the standing position is shown, but the present invention is not limited to this case. 1 to 4, it is described that the Bucky device 51 and the CR device 52 are installed in all the shooting rooms R. However, the present invention is not limited thereto. Only the Bucky device may be installed, and the other photographing room R may be configured to install only the CR device. That is, the radiographic imaging system 100 as a whole may be in a state where the bucky device 51 and the CR device 52 that can be loaded with the radiographic imaging device 1 are mixed.

  As described above, the bucky device 51 is an existing bucky device formed so as to be loaded with a CR cassette in the cassette holding portion (cassette holder) 51a in this embodiment, and holds the radiographic image capturing device 1 in the cassette. The unit 51a can be loaded and used.

  The radiographic image capturing apparatus 1 can be used in a state where it is loaded in the bucky device 51, but can also be used in a single state where it is not loaded in the bucky device 51. That is, the radiation image capturing apparatus 1 is disposed on the upper surface side of, for example, a bed provided in the capturing room Ra or a bucky apparatus 51 for lying position photographing as shown in FIG. 12, and its radiation incident surface R (see FIG. 1). ) The patient's hand or the like as the subject can be placed on the head, or can be used, for example, by being inserted between the patient's waist or legs lying on the bed and the bed. .

  In this embodiment, as shown in FIG. 13, the CR device 52 includes a detection unit 52a supported by a support column 52b so as to be movable up and down. In the following description, the CR device 52 for standing position shooting will be described. However, the same description can be applied to the case where the CR device 52 is for standing position shooting, for example.

  The detection unit 52 a of the CR device 52 is provided with a radiation image conversion plate 52 c formed of a stimulable phosphor sheet or the like at a predetermined position inside the detection unit 52. In addition, an irradiation device 52d that irradiates the radiation image conversion plate 52c with excitation light such as laser light is provided in the detection unit 52a, and the irradiation device 52d moves relative to the radiation image conversion plate 52c. Therefore, the excitation light to be irradiated is scanned in the horizontal direction by a polygon mirror or the like while moving its position in the vertical direction, and the excitation light is sequentially irradiated to the entire reading range of the radiation image conversion plate 52c. It has become.

  Thus, when the radiation image conversion plate 52c is irradiated with excitation light, the radiation energy accumulated in the position (pixel) where the excitation light of the stimulable phosphor layer of the radiation image conversion plate P is incident is stimulated. Radiated as light (fluorescence). Therefore, in the detection unit 52a, a photoelectric conversion device including a photomultiplier or the like that collects and amplifies and detects the stimulated light emitted from the radiation image conversion plate 52c and outputs a logarithmically compressed digital signal value. 52e is provided.

  The CR device 52 reads out the energy of the radiation applied to the radiation image conversion plate 52c through the subject at the time of radiographic imaging in this way as the stimulating light, thereby acquiring the image data D in the radiographic imaging.

  The storage unit Cb stores in advance a table in which a shooting room ID, which is identification information of the shooting room R, and a base station ID of the base station 55 provided in the shooting room R are associated with each other. When information such as image data D is transmitted via the base station 55, the console C refers to the table and the imaging room in the imaging room R corresponding to the base station ID of the base station 55 added to the information. An ID is determined, and it is determined that the information is information transmitted from the imaging room R from which the information has been determined.

  As shown in FIG. 1 and the like, each photographing room R (R1 to R4) is connected to each console C (C1 to C3) by a predetermined connection method (in the case of FIG. 1), or a network N (In the case of FIG. 2). That is, in each console C (C1 to C3), each base station 55 and each console 59 (not shown in FIG. 1 and FIG. 2; see FIG. 12) of each photographing room R (R1 to R4) are predetermined. They are connected in a connection manner or via the network N.

  As will be described later, in the console C, radiographing order information representing the contents of radiographic imaging performed in a predetermined radiographing room R is managed for each radiographing room, and the radiographing order information is managed from the console C to the console 59 of the radiographing room R. The console C and the imaging room R are associated with each other so that imaging conditions such as tube current and tube voltage at the time of each imaging can be automatically set in the radiation generator 53.

  Prior to radiographic imaging, radiographic imaging imaging order information generated in advance from the HIS or RIS connected to the network N is transmitted to each console C in a list format. In any console C, order information for photographing in each photographing room is selected from this list.

  In this embodiment, as shown in FIG. 15, the imaging order information includes “patient ID” P2, “patient name” P3, “gender” P4, “age” P5, “clinical department” P6 as patient information. And “imaging region” P7 and “imaging direction” P8 as imaging conditions. Then, “shooting order ID” P1 is automatically assigned to each shooting order information in the order in which the shooting orders are received.

  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 can also be configured as described above, and can be set as appropriate.

  When radiographing order information of radiographic imaging is acquired from the HIS or RIS, a list of each list of radiographing order information is displayed on the display unit Ca of the console C as a selection screen H1, as shown in FIG. It has become.

  In the present embodiment, the selection screen H1 is provided with a shooting order information display field h11 for displaying a list of each shooting order information, and on the left side of the shooting order information display field h11 is a target shooting room R. A selection button h12 for selecting shooting order information scheduled to be shot at is provided corresponding to 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.

  The operator clicks the selection button h12 to select one or more pieces of shooting order information scheduled to be shot in the target shooting room R, and clicks the decision button h13. And although illustration is abbreviate | omitted, the target imaging | photography room R is selected on the screen which selects imaging | photography room R1-R4 displayed after clicking the determination button h13. When each shooting order information and the target shooting room R are selected, a list of each selected shooting order information is associated with the shooting room ID of the target shooting room R and stored in the storage unit Cb.

  At the same time, a list of each shooting order information selected from the console C operated by the operator is transmitted to the console 59 of the target shooting room R or the like. As described above, the list of imaging order information is transmitted from the console C to the target imaging room R, and as described above, the console C and the target imaging room R are associated with each other.

  Note that before creating the list of shooting order information, it is also possible to select the target shooting room R first and associate the console C with the target shooting room R. Further, when the console C and the shooting room R are associated with each other in a one-to-one correspondence like the console C1 and the shooting room R1 in FIG. 1, the shooting room after the operator clicks the determination button h13. The display of the screen for selecting R may be omitted.

  When the target shooting room R is selected on the screen for selecting the shooting room R, the console C subsequently displays various icons I on the display unit Ca as illustrated in FIGS. 17 and 18. It has become.

  Specifically, in this embodiment, as shown in FIG. 17 and FIG. 18, on the left side of the selection screen H <b> 2, with the notation of “posture” surrounded by a rectangular frame, An icon I-51 corresponding to the device 51 is displayed. In the example shown in FIG. 12, since the device for standing shooting is the CR device 52, similarly, on the left side of the selection screen H <b> 2, the notation of “standing CR” is surrounded by a rectangular frame line, An icon I-52 corresponding to the CR device 52 for standing shooting is displayed. In addition, on the right side of the selection screen H2, icons I-1a to I-1c corresponding to the radiation image capturing apparatuses 1 existing in the imaging room Ra are displayed, and the icons I-1a to I-1c are displayed. Numbers 1 to 3 are attached and displayed in each rectangular frame.

  In the present embodiment, if the radiographic imaging device 1 is not loaded in the bucky device 51, the console C displays the frame line of the icon I-51 corresponding to the bucky device 51 with a broken line ("" in FIG. 17 The icon “I-51” of “Longitudinal position”) is displayed, indicating that the radiographic imaging device 1 is not loaded in the bucky device 51.

  Further, when the radiographic imaging device 1 is loaded in the bucky device 51, the console C has an icon I corresponding to the bucky device 51, as indicated by an “I-position” icon I-51 in FIG. The frame line of -51 is displayed as a solid line, and the inside of the frame line is colored with a predetermined color and displayed to indicate that the radiographic imaging device 1 is loaded in the bucky device 51. ing. In FIG. 18, the number, resolution, and the like of the radiographic imaging device 1 loaded in the bucky device 51 are displayed in the vicinity of the icon “I-51” in the “recumbent position”.

  In the present embodiment, for example, by clicking the icon I-1 corresponding to the radiographic image capturing apparatus 1 shown in FIG. 17 or FIG. 18, the radiographic image capturing apparatus 1 is selected as a radiographic image capturing apparatus to be used in the future. Can be done. As described above, when the selection switch 38 of the radiographic image capturing apparatus 1 is pressed, the radiographic image capturing apparatus 1 can be selected as a radiographic image capturing apparatus to be used from now on.

  Further, when the radiographic imaging device 1 is brought into the radiographing room R, for example, when the radiographic imaging device 1 is newly brought into the associated radiographing room R, the console C displays the display of the console C. An icon I-1 corresponding to the radiographic imaging device 1 is newly displayed on the selection screen H2 of the part Ca.

  Further, for example, after clicking the icon I-1c corresponding to the radiation image capturing apparatus 1 of number 3 shown in FIG. 17, the icon I-51 corresponding to the Bucky apparatus 51 is clicked, or the icon I-1c is clicked. It is possible to specify in advance that the radiographic imaging device 1 of number 3 is to be loaded into the bucky device 51 by an icon operation such as dragging and dropping the icon I-51 onto the icon I-51. When operated in this way, the selection screen H2 is switched from the state of FIG. 17 to the state of FIG.

  In the present embodiment, when the radiographic imaging device 1 to be loaded in the bucky device 51 is designated in advance on the selection screen H2 of the console C in this way, the radiographing room R selected from the console C at that point in time A signal indicating that the bucky device 51 has been designated is transmitted to the console 59 in the photographing room R.

  Then, when the signal is transmitted, the console 59 activates the radiation generating device 53A (see FIG. 12), and the bucky device 51 designated based on the transmitted signal (for example, the supine position in FIG. 12). The radiation generating device 53A is moved so that the radiation can be appropriately applied to the imaging bucky device 51), the radiation direction is adjusted, and the radiation is irradiated within a predetermined range of the bucky device 51 (not shown). The radiation generator 53 is adjusted so that the diaphragm is adjusted and an appropriate dose of radiation is emitted.

  In the present embodiment, the icon operation is performed by clicking the icon I-52 corresponding to the CR device 52 (the CR device 52 for standing shooting in FIG. 17 or the like) on the selection screen H2 of the console C. Thus, a predetermined CR device 52 can be designated in advance.

  Further, when the CR device 52 is designated in advance on the selection screen H2 of the console C in this way, a signal indicating that the CR device 52 is designated in the photographing room R selected from the console C at that time is displayed. Based on the transmitted signal, the operation console 59 activates the radiation generating device 53A and designates the designated CR device 52 (for example, for standing imaging in FIG. 12). The CR device 52) is moved so that the radiation can be appropriately irradiated, the radiation direction is adjusted, and a diaphragm (not shown) is provided so that the radiation is irradiated within a predetermined range of the CR device 52. The radiation generator 53 is adjusted so that an appropriate dose of radiation is applied.

  If comprised in this way, it will become possible to start the radiation generator 53 beforehand by operation with the console C, and it will become possible to take a radiographic image immediately in the stage which the operator moved to the imaging room R. There is an advantage such as.

  Note that, as described above, although it is specified on the selection screen H2 of the console C that the radiographic imaging device 1 is loaded into the bucky device 51 or the CR device 52 is specified to perform imaging, For example, when an operator who has moved to the shooting room R tries to take a picture without using a designated device, for example, a process such as issuing a sound and warning may be performed.

  Although not shown in FIGS. 17 and 18, when a portable radiation generator 53B (see FIG. 12) exists in the imaging room R, a corresponding icon I is displayed on the selection screen H2 of the console C. In the same manner as in the case of the radiation generating apparatus 53A, the portable radiation generating apparatus 53B can be activated by operating the console C.

  The above is the situation when the operator operates the console C prior to radiographic imaging. After the operator moves to the imaging room R, for example, the selection switch 38 of the radiographic imaging apparatus 1 is pressed. When a selection signal indicating that the radiographic imaging apparatus 1 has been selected is transmitted from the radiographic imaging apparatus 1, the console C is colored with an icon I-1 corresponding to the radiographic imaging apparatus 1 on the selection screen H2. The fact that the radiographic imaging device 1 has been selected is displayed by being displayed.

  On the other hand, when the radiographic image capturing based on the radiographing order information is completed in the associated radiographing room R, the above-described thinning data Dt is transmitted from the radiographic image capturing device 1 via the antenna device 41 and the base station 55. Then, the console C refers to the base station ID added to the thinning data Dt and transfers the thinning data Dt to the base station 55, that is, the radiographing room R in which the radiographic imaging is performed. Yes.

  When the image data D is transmitted from the CR device 52, the console C thins out the image data D transmitted from the CR device 52 at a predetermined rate in the same manner as in the case of the radiographic image capturing device 1. Data Dt is created. Then, the console C refers to the base station ID added to the image data D that is the basis of the creation of the thinned data Dt, and the created thinned data Dt is used for the base station 55, that is, the radiographic imaging. The image is transferred to the shooting room R.

  At this time, the thinned data Dt is also displayed on the display unit Ca of the console C as a preview image. It is also possible to configure so that this display is performed only when there is an operation by the operator. Further, it is also possible to configure so that the thinned data Dt created from the image data D photographed based on the photographing order information is stored in the storage unit Cb in association with the photographing order information.

  After the thinned data Dt is transmitted from the radiation image capturing apparatus 1, the console C receives the corresponding image data D that is the basis for creating the thinned data Dt and the dark read value d read in the dark reading process. When transmitted from the radiographic image capturing apparatus 1 via the antenna device 41 or the base station 55, these data are stored in the storage means Cb in association with each imaging order information.

  On the console C, image processing is performed based on the image data D and the dark read value d transmitted from the radiographic image capturing apparatus 1 or the image data D transmitted from the CR apparatus 52, and the imaging order. A final diagnostic radiographic image based on the information is generated. When this final diagnostic radiographic image is generated, the console C also associates the final diagnostic radiographic image with the imaging order information. The data is stored in the storage means Cb.

  The management device S (see FIG. 1 and the like) includes a server 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. The management device S is connected to a storage means Sa composed of a hard disk or the like. The storage means Sa is provided with a shooting room ID which is identification information of the shooting room R and the shooting room R. A table in which the base station ID of the base station 55 is associated is stored in advance.

  The management apparatus S receives various information via the base station 55, via the console C in the systems shown in FIGS. 1 and 3, and via the network N in the systems shown in FIGS. Referring to the table, the shooting room ID of the shooting room R corresponding to the base station ID of the base station 55 added to the information is determined, and the information is transmitted from the shooting room R from which the information is determined. By discriminating, the information is stored in the storage means Sa in association with the photographing room ID of the photographing room R.

  In addition, when the cradle 57 is configured to be used for registration of the radiographic imaging device 1 brought into the imaging room R as described above, the management device S moves the base station 55 from the cradle 57. The cassette ID of the radiographic imaging device 1 transmitted via the radiographic imaging device 1 is stored in the storage means Sa in association with the radiographic room ID of the imaging room R, and the radiographic imaging device 1 is one of the plurality of imaging rooms R1 to R4. It is managed whether or not it exists in any of the shooting rooms R.

  Next, the operation of the radiographic image capturing system 100 according to the present embodiment will be described.

  As described above, in the radiographic imaging system 100 according to the present embodiment, as in the radiographic imaging system described in Patent Document 1, it is required to provide a display unit on each support stand of the radiographic imaging apparatus. Instead, the display device 56 including the screen 56a is simply installed at a predetermined position in the photographing room R, for example, an inner wall near the door. Therefore, it is possible to save the trouble of providing a display unit on each support base.

  When radiographic imaging is performed, the thinning data Dt for preview is transmitted from the radiographic imaging apparatus 1 to the console C via the base station 55, and this thinning data Dt is displayed from the console C via the base station 55. Transferred to device 56. Also, the image data D is transmitted from the CR device 52 to the console C via the base station 55, the preview thinning data Dt is created by the console C based on the image data D, and the thinning data Dt is transmitted from the console C to the base C It is transferred to the display device 56 via the station 55.

  Then, based on the thinning data Dt, a preview image of an image obtained by imaging immediately after radiographic imaging is displayed on the screen 56a of the display device 56 in the imaging room R. Therefore, it is not necessary for an operator such as a radiologist who has taken an image in the imaging room R to leave the imaging room R and see the preview image displayed on the display screen Ca of the console C.

  As described above, the operator operates the switch means 58 in the front chamber Rb even when performing the standing position photographing, the standing position photographing, or the portable photographing using the bucky device 51 or the CR device 52 loaded with the radiation image photographing device 1. After several seconds until the camera room Ra is entered later, for example, 5 seconds later, a preview image is displayed on the screen 56a of the display device 56 in the camera room R. Therefore, the operator performs an X-ray irradiation switch operation in the front room Rb of the photographing room R, and sees the preview image in the photographing room R at the timing when returning from the front room Rb to the photographing room Ra for the next photographing. This makes it possible to confirm the success or failure of positioning, and eliminates the need to wait in the front room until a preview is displayed. Therefore, the radiographic image capturing system 100 according to the present embodiment is very convenient for the operator.

  In addition, since an operator in the photographing room R can see the preview image on the spot, it is determined whether or not the subject is correctly photographed by the radiographic image photographing device 1, and the necessity of re-photographing is immediately determined. It becomes possible to judge. For this reason, the patient is not allowed to wait for a long time until the necessity of re-photographing is determined, and the burden on the patient can be reduced. In addition, when the X-ray irradiation switch is operated, it takes a very short time to leave the patient alone in the imaging room Ra, and the patient can be sufficiently cared for.

  In addition, the preview image displays the log-compressed thinned data Dt regardless of whether the radiographic image capturing apparatus 1 or the CR apparatus 52 is used, so that the operator is not aware of the type of the image capturing apparatus. It is possible to determine the success or failure of positioning by the same method.

  As described above, according to the radiographic image capturing system 100 according to the present embodiment, the display device 56 is simply installed in the radiographing room R with respect to the existing system in which the radiographic image capturing apparatus 1 and the CR apparatus 52 are mixed. The system can be configured with. Therefore, the system can be easily constructed, and the system can be introduced at a low cost.

  When radiographic imaging is performed, the thinning data Dt for preview is automatically transmitted from the radiographic imaging apparatus 1 to the console C, and based on the image data D automatically transmitted from the CR apparatus 52. The thinned data Dt is automatically created by the console C. Then, the thinned data Dt is automatically transferred from the console C to the display device 56, and based on this, a preview image is displayed on the screen 56a.

  Therefore, the X-ray irradiation switch operation is performed in the front room Rb of the radiographing room R, the operator returns to the radiographing room Ra from the front room Rb for the next radiographing, and an operator such as a radiographer in the radiographing room Ra is on the spot Since the preview image can be viewed and the necessity of re-shooting can be determined, the next shooting can be started quickly, which is very convenient for the operator. In addition, when the X-ray irradiation switch is operated, it takes a very short time to leave the patient alone in the imaging room Ra, and the patient can be sufficiently cared for.

  In the above embodiment, the case where the radiographic image capturing apparatus 1 creates the thinned data Dt from the image data D and transmits it to the console C has been described. With this configuration, since the data amount of the thinned data Dt is smaller than that of the image data D, the data transmission time is shortened, and the time until the preview image is displayed on the display device 56 can be shortened. In particular, when the radiographic imaging apparatus 1 is a portable radiographic imaging apparatus including a battery 24 (see FIG. 11), it is possible to reduce the power consumption of the battery 24. There are advantages.

  However, for example, when the radiographic image capturing apparatus 1 is an integrated radiographic image capturing apparatus formed integrally with the support base, the radiographic image capturing apparatus 1 is connected to the base station 55 with a cable. There are many cases. In such a case, even if the image data D is transmitted directly to the console C without creating the thinned data Dt, the image data D is normally transmitted at a very high speed.

  Therefore, in such a case, not only the CR device 52 but also the radiographic image capturing device 1 transmits the image data D to the console C, and the thinned data Dt is transmitted by the console C based on the transmitted image data D. It is also possible to create and transfer it to the display device 56 via the base station 55.

  And even if comprised in this way, it becomes possible to acquire the completely same effect as the radiographic imaging system 100 which concerns on said this embodiment. Even when the radiographic imaging apparatus 1 is portable, it is possible to transmit the image data D from the radiographic imaging apparatus 1 to the console C and create the thinned data Dt by the console C.

  In addition, it goes without saying that the present invention is not limited to this embodiment and can be changed as appropriate. For example, in addition to the preview image, information related to the irradiation dose at the time of photographing obtained by analyzing the photographed image data may be displayed as in the sensitivity (S value) of JP-A-11-327066.
