Description

  The present invention relates to a radiation image detection device that generates radiation image data by detecting radiation typified by X-rays, a control device that controls the radiation image detection device, and radiation using the radiation image detection device and the control device. The present invention relates to an image capturing system.

  In the field of medical diagnosis, a CR (Computed Radiography) system capable of handling radiographic images as digital data has been put into practical use. This CR system includes a reading device that reads radiation image data by scanning a phosphor plate built in a CR cassette with excitation light, and a control device (also called a console) that acquires the radiation image data read by the reading device. ) And are connected. Then, by reading the CR cassette irradiated with radiation in the radiography room with the reading device, and transmitting and displaying the obtained radiation image data to the control device, the radiographer has obtained the optimal radiation image data. Can be confirmed.

  In recent years, it has been proposed to introduce a large-scale CR system in which a plurality of reading devices and a plurality of control devices are connected via a network in order to support use in medical institutions equipped with a plurality of radiography rooms (patents). Reference 1). In the large-scale CR system as described in Patent Document 1, there are a plurality of patients to be imaged at a time, and there are also a plurality of radiographers who perform imaging operations. There is. Accordingly, instruction information called imaging order information including patient information (patient name, age, etc.) and imaging information (imaging date, imaging region, imaging direction, etc.) is generated in advance, and the imaging order information and CR A method is adopted in which a cassette ID (identification information) for identifying a cassette is registered in association with each other. Thus, by associating one imaging order information with one CR cassette, the radiation image data obtained by reading the CR cassette with the reader is associated with the imaging order information based on the cassette ID of the CR cassette. Therefore, it is possible to prevent the radiation image data from being mixed up.

  On the other hand, instead of the above-mentioned CR cassette, an FPD (incorporating radiation detection elements two-dimensionally arranged on the substrate and outputting an electrical signal corresponding to the radiation dose irradiated to the radiation detection elements) A Flat Panel Detector device has been proposed as a radiation image detection device (see, for example, Patent Document 2). By using this FPD device, it is possible to obtain radiation image data directly without irradiating excitation light and reading a radiation image, and thus the system itself is simplified compared to the case of using a CR cassette. This makes it possible to perform shooting work smoothly. In addition, since a plurality of radiation image data can be stored in the storage unit built in the FPD device, a plurality of images can be continuously taken at a time, and the imaging efficiency is improved.

From such excellent convenience of the FPD device, as disclosed in Patent Document 2, it is assumed that the FPD device will be applied to the large-scale CR system described above.

This is a portable cassette FPD device that accommodates an imaging panel called.

  Hereinafter, the structure of the radiation image detection apparatus 6 will be described with reference to FIGS. 3 and 4. FIG. 3 is a perspective view of the radiation image detection apparatus 6. As shown in FIG. 3, the radiation image detection device 6 includes a housing 61 that protects the inside, and is configured to be portable as a cassette.

  An imaging panel 62 serving as an image data generation unit that converts irradiated radiation into an electrical signal is formed in layers inside the casing 61. A light emitting layer (not shown) that emits light according to the intensity of the incident radiation is provided on the radiation irradiation side of the imaging panel 62.

  The light emitting layer is generally called a scintillator layer. For example, a phosphor is a main component, and based on incident radiation, an electromagnetic wave having a wavelength of 300 nm to 800 nm, that is, visible light to ultraviolet light to infrared light. Output electromagnetic waves (light).

  The electromagnetic wave (light) output from the light emitting layer is converted into electric energy and accumulated on the surface opposite to the surface on which the radiation of the light emitting layer is irradiated, and an image signal based on the accumulated electric energy is stored. A signal detection unit 600 in which photoelectric conversion units that perform output are arranged in a matrix is formed. Note that a signal output from one photoelectric conversion unit is a signal corresponding to one pixel serving as a minimum unit constituting the radiation image data.

  Here, a circuit configuration of the imaging panel 62 will be described. FIG. 4 is an equivalent circuit diagram of the signal detection unit 600 in which the photoelectric conversion units are two-dimensionally arranged. As shown in FIG. 4, the configuration of the photoelectric conversion unit includes a photodiode 601 and a thin film transistor (TFT) 602 that extracts electrical energy accumulated in the photodiode 601 as an electrical signal by switching. .

  At the time of signal reading, the scanning drive circuit 609 is driven to turn on the TFT 602, whereby the charge accumulated in the photodiode 601 is transmitted to the amplifier 603 as an electric signal. This electric signal is amplified to a level that can be detected by the signal readout circuit 608 by the amplifier 603. The voltage value of the amplifier 603 is temporarily held by the sample hold circuit 605 and then applied to the analog multiplexer 606.

  In the analog multiplexer 606, the obtained voltage value is converted into a serial electric signal and transmitted to the A / D converter 607. The A / D converter 607 converts this electric signal into digital data. In this way, radiation image data is generated by the imaging panel 62.

  The ROM 81 is configured by a nonvolatile semiconductor memory or the like, and stores a control program executed by the control unit 60, various programs, and the like.

  The RAM 82 forms a work area that temporarily stores various programs, input or output data, parameters, and the like that can be executed by the control unit 60 read from the ROM 81 in various processes that are executed and controlled by the control unit 60. .

[First Embodiment]
FIG. 9 is a flowchart for explaining the operation of the radiation image capturing system 200 according to the first embodiment. With reference to this figure, a series of operations for generating a plurality of radiation image data by one radiation image detection device 6 and transmitting the plurality of radiation image data to the console 7 will be described. In this embodiment, a plurality of pieces of radiographing order information relating to radiography are input in advance by a doctor or a receptionist, and the radiographing order information list shown in FIG. 6 is stored in the external storage device of the RIS server 2. Shall.

  First, when starting radiography, an operator such as a doctor or a radiographer operates the input operation unit 18 of the console 7 and inputs information indicating that radiography is started. When receiving information indicating that radiation imaging is started from the input operation unit 18, the control unit 14 of the console 7 receives the imaging order information list stored in the external storage device of the RIS server 2 and receives the imaging order information list. It memorize | stores in the memory | storage part 21 (step S1). Then, an input screen 171 for inputting shooting order information corresponding to the current shooting is displayed on the display unit 17 (step S2).

  FIG. 7 shows an example in which an input screen 171 for inputting photographing order information is displayed on the display unit 17. As shown in FIG. 7, the input screen 171 is provided with a first imaging order information display field 171 a for displaying the imaging order information list stored in the storage unit 21. The imaging order information included in the imaging order information list includes “imaging order ID” P1, “patient ID” P2, “patient name” P3, “gender” P4, “age” P5, “clinic department” P6, “ It is configured to include “imaging region” P7 and “imaging direction” P8. The operator operates the input operation unit 18 while confirming the first shooting order information display field 171a of the display unit 17, and clicks an item on which one shooting order information corresponding to the current shooting is displayed. Here, it is assumed that the shooting order information item whose “shooting order ID” P1 is “001” is clicked.

  The control unit 14 of the console 7 receives the input from the input operation unit 18 and selects the imaging order information whose “imaging order ID” P1 is “001” from the imaging order information list stored in the storage unit 21. (Step S3; selection means). Then, whether or not the selected one imaging order information and other imaging order information stored in the storage unit 21 have a predetermined relationship, specifically, included in the selected imaging order information. It is determined whether or not the “patient ID” P2 and the “patient ID” P2 included in the other imaging order information are the same (step S4; determination means). That is, in this step, it is determined whether or not “patient ID” P2 of other imaging order information is “100085”. The imaging order information whose “patient ID” P2 is “100085” among the other imaging order information is displayed on the display unit 17 as the discrimination result screen 172 (step S5).

  FIG. 8 is a diagram showing an example in which a discrimination result screen 172 showing the discrimination result is displayed on the display unit 17. As shown in FIG. 8, a selected shooting order information display field 172a for displaying the shooting order information selected in step S3 is provided at the top of the discrimination result screen 172. In the center of the discrimination result screen 172, a second imaging order information display field 172b for displaying imaging order information having the same “patient ID” P2 as the selected imaging order information is provided. In addition, a “decision button” 172c and a “return button” 172d are provided at the bottom of the determination result screen 172. Note that, as will be described later, only the imaging order information displayed in the second imaging order information display field 172b is permitted for additional selection, and this corresponds to the permission means in the present invention.

  The operator operates the input operation unit 18 while confirming the second imaging order information display field 172b of the display unit 17, and desires from the imaging order information displayed in the second imaging order information display field 172b. Click the shooting order information item. Normally, in one imaging flow, it is more efficient to select a plurality of imaging order information and perform a plurality of radiation imagings together. Therefore, here, the “imaging order ID” P1 is “002” and It is assumed that the photographing order information having “003” is clicked together. When the input of the imaging order information is completed, the “OK” button 172c is clicked. To return to the previous process, click the “return button” 172d.

  The control unit 14 of the console 7 receives the input from the input operation unit 18 and additionally selects the imaging order information whose “imaging order ID” P1 is “002” and “003” (step S6). Then, the imaging order information selected in step S3 and the imaging order information selected in step S6 are associated with each other and stored in the storage unit 21 (step S7). When the storage in the storage unit 21 is completed, a cassette ID input screen such as “Please input the cassette ID of the radiation image detection device 6” is displayed on the display unit 17 (not shown).

  The operator selects one radiological image detection apparatus 6 suitable for the current imaging from those that are currently usable. Then, the cassette ID of the radiation image detection apparatus 6 is input by operating the input operation unit 18. The control unit 14 of the console 7 receives the input from the input operation unit 18, associates the input cassette ID with the three imaging order information stored in the storage unit 21 in step S 7, and stores them in the storage unit 21. Store (step S8). Then, the imaging information included in the imaging order information is transmitted to the imaging operation device 4, and the console ID of the console 7 is transmitted to the radiographic image detection device 6 through the base station 5 by wireless communication. This completes the preparation for shooting.

  When the above-described preparation for imaging is completed, the operator mounts the selected radiation image detection device 6 on the detection device mounting port 11a of the supine imaging table 11. At this time, the radiation image detection device 6 enters a photographing standby state (step S9). Further, the operator places the imaging region of the patient 12 on the supine imaging table 11 so that the imaging region indicated in the imaging information is at an appropriate position with respect to the radiographic image capturing device 3. Then, by controlling the imaging operation device 4 based on the imaging information received from the console 7, radiation based on the imaging information is emitted from the radiation imaging device 3.

  The control unit 60 of the radiographic image detection device 6 detects the radiation irradiated from the radiographic image capturing device 3 and transmitted through the patient 12, generates radiographic image data in the above-described process, and stores it in the image storage unit 66 (step). S10). As a result, the image storage unit 66 stores radiographic image data for one radiograph corresponding to one radiographing order information. In the present embodiment, as described above, since the three pieces of imaging order information are selected corresponding to the radiation image detection apparatus 6, the operation in step S10 is repeated three times to correspond to the three pieces of imaging order information. The radiographic image data for three radiographs is stored in the image storage unit 66. In addition, when performing this imaging | photography several times, of course, it is also possible to image | photograph over several radiation imaging rooms.

  When the imaging is finished (step S11: Yes), the operator takes out the radiation image detection device 6 from the detection device mounting opening 11a of the supine imaging stand 11 and presses a transmission button (not shown) of the radiation image detection device 6. To do. When receiving the input of the transmission button, the control unit 60 of the radiological image detection apparatus 6 attaches a cassette ID to the radiographic image data for three radiographs stored in the image storage unit 66, and these are attached from the communication unit 83 to the base station 5. Is transmitted by wireless communication (step S12). At this time, the transmission destinations of the radiographic image data and the cassette ID for three radiographs are determined based on the console ID received in advance, and here the console 7 is set as the transmission destination.

  The control unit 14 of the console 7 receives the radiation image data and the cassette ID transmitted from the radiation image detection device 6 (step S13). Then, image processing such as A / D conversion, normalization processing, and gradation processing is performed on the radiographic image data for three radiographs and stored in the storage unit 21. Next, the radiographic image data for three radiographs stored in the storage unit 21 and the radiographing order information associated with the cassette ID in step S8 are displayed on the display unit 17 (step S14).

  The operator operates the input operation unit 18 while confirming the display on the display unit 21, and associates the radiographic image data for three radiographs with the three radiographing order information. In the present embodiment, as described above, only the same patient is selected as the imaging order information, and radiation imaging is performed based on this imaging order information. For this reason, since the operator can distinguish each of the plurality of radiographic image data, it is possible to accurately determine which radiographic image data corresponds to which radiographing order information. That is, normally, when the same patient is imaged a plurality of times, it is unlikely that the same region or a similar region is imaged twice during one imaging flow. Accordingly, even if radiation image data obtained from the same patient is stored in the same radiation image detection device 6, the radiation image data can be easily distinguished.

  And the control part 14 of the console 7 receives the input from the input operation part 18, and matches imaging | photography order information and radiographic image data, respectively (step S15). And these are memorize | stored in the memory | storage part 21, and this flow is complete | finished.

  Thus, in this embodiment, a plurality of radiographs are generated using one radiographic image detection device 6 to generate radiographic image data for a plurality of radiographs. Then, when selecting a plurality of radiographing order information respectively corresponding to the radiographic image data for a plurality of radiographs, when one radiographing order information is selected, the “patient ID” P2 of the one radiographing order information and another Whether or not the “patient ID” P2 of the imaging order information is the same is determined, and only other imaging order information that is the same can be additionally selected. As described above, in general, when the same patient is imaged a plurality of times, it is unlikely that the same region or a similar region is imaged twice during one imaging flow.

  For this reason, even if the same patient is imaged multiple times by one radiographic image detection device 6 and the generated radiographic image data for a plurality of radiographs are stored simultaneously, the radiographic image data for the plurality of radiographs is displayed on the console 7. Then, the operator can distinguish which radiographic image data corresponds to which radiographing order information. Therefore, even if the radiographic image data and the radiographing order information are erroneously associated with each other, the operator can easily notice the erroneous association, and this can be accurately associated. Therefore, it is possible to prevent the radiation image data from being mistaken and to suppress the occurrence of a medical error.

  In addition, when selecting radiographing order information, it is not necessary for the doctor himself / herself to select which radiographing order information can identify the radiographic image data, thereby improving work efficiency.

  In addition, since the discrimination result screen 172 showing the discrimination result is displayed on the display unit 17 and the imaging order information permitted to be additionally selected is input on the discrimination result screen 172, the imaging order capable of additional selection is configured. Information can be determined at a glance, and it is possible to reduce omission of selection of imaging order information by an operator.

  In the above-described embodiment, the “patient ID” that is the same as the “patient ID” P2 of the selected one imaging order information as the imaging order information having a predetermined relationship with the selected one imaging order information. Although it is set as having P2, it is of course not limited to this. For example, it is set as imaging order information having “imaging part” P7 different from “imaging part” P7 included in one selected imaging order information, as having a predetermined relationship with the selected one imaging order information. Alternatively, it may be set as imaging order information having “imaging site” P7 and “imaging direction” P8 in which at least one of “imaging site” P7 and “imaging direction” P8 is different.

  With this setting, even if a plurality of radiographic image data obtained by imaging different patients are simultaneously stored in one radiographic image detection device 6, the operator can select which radiographic image data corresponds to which radiographing order information. Can be distinguished. Therefore, radiation imaging can be performed across a plurality of patients in one imaging flow, and imaging efficiency is further improved. On the other hand, for example, when imaging L and R in the vertical direction (also referred to as CC) of the breast part, the radiographic image data cannot be distinguished even if the “imaging direction” P8 is different. When the radiographic image data cannot be distinguished like CC-L and CC-R of the breast part, simultaneous selection is prohibited. As described above, having a predetermined relationship in the present invention can be set as appropriate according to each work mode as long as the operator can recognize the radiation image data.

In the above description, when additional photographing order information is selected, the operator inputs from the input operation unit 18 and is selected. However, as described above, in one imaging flow, it is more efficient to select a plurality of imaging order information and perform a plurality of radiation imagings together. Order information may be automatically selected. This configuration eliminates the need for the doctor to select additional imaging order information by himself, thus improving work efficiency and automatically selecting all imaging order information that can be captured in one imaging flow. It is possible to prevent omission of selection of the imaging order information.
[Second Embodiment]
In the first embodiment, the console 7 is configured to determine whether other imaging order information has a predetermined relationship with one imaging order information. However, in the present embodiment, the radiographic image detection apparatus. It is configured to discriminate with 6. In addition, since the basic apparatus configuration in the present embodiment is almost the same as that of the first embodiment, only portions different from the first embodiment will be mainly described below.

  As shown in FIG. 5, the control system of the radiation image detection apparatus 6 includes a control unit 60, an imaging panel 62, an image storage unit 66, a power supply unit 67, a ROM 81, a RAM 82, a communication unit 83, and the like. It is connected. Among these, the imaging panel 62, the image storage unit 66, the power supply unit 67, the ROM 81, and the communication unit 83 have the same functions as those in the first embodiment, and thus description thereof is omitted here.

  The RAM 82 forms a work area for temporarily storing various programs executed and controlled by the control unit 60, input or output data, parameters, and the like. Further, as described later, the imaging order information transmitted from the console 7 is temporarily stored. That is, in the present embodiment, the RAM 82 corresponds to the imaging order information storage unit.

  The control unit 60 reads out a control program stored in the ROM 81, develops it in a work area formed in the RAM 82, and controls each unit of the radiation image detection apparatus 6 according to the control program. Further, it is determined whether or not one shooting order information stored in the RAM 82 and other shooting order information transmitted from the console 7 have a predetermined relationship. Further, only the other imaging order information having a predetermined relationship is allowed to be additionally selected. That is, in the present embodiment, the control unit 60 corresponds to a determination unit and a permission unit.

  10 and 11 are flowcharts for explaining the operation of the radiation image capturing system 200 according to the second embodiment. With reference to these drawings, a series of operations for generating a plurality of radiation image data by one radiation image detecting device 6 and transmitting the plurality of radiation image data to the console 7 will be described.

  First, when starting radiography, the operator operates the input operation unit 18 of the console 7 and inputs information indicating that radiography is started. When receiving information indicating that radiation imaging is started from the input operation unit 18, the control unit 14 of the console 7 receives the imaging order information list stored in the external storage device of the RIS server 2 and receives the imaging order information list. It memorize | stores in the memory | storage part 21 (step S21). Then, as shown in FIG. 7, an input screen 171 for inputting shooting order information corresponding to the current shooting is displayed on the display unit 17 (step S22). Here, as in the first embodiment, it is assumed that an item of imaging order information whose “imaging order ID” P1 is “001” is clicked.

  The control unit 14 of the console 7 receives the input from the input operation unit 18 and selects the imaging order information whose “imaging order ID” P1 is “001” from the imaging order information list stored in the storage unit 21. (Step S23; selection means). Then, the selected radiographing order information and the console ID of the console 7 are transmitted to the radiological image detection apparatus 6 through the base station 5 by wireless communication (step S24).

  When receiving the one imaging order information and the console ID from the console 7, the control unit 60 of the radiation image detecting apparatus 6 stores the one imaging order information as the selected imaging order information in the RAM 82 (step S25). Then, the console 7 having the received console ID is set as a transmission destination, and a response signal indicating the reception is transmitted to the console 7 (step S26).

  When the control unit 14 of the console 7 receives the response signal from the radiation image detection device 6, the control unit 14 displays the input screen 171 on the display unit 17 again (step S27). In this step, it is preferable that the imaging order information selected in step S23 is not displayed or input.

  The operator operates the input operation unit 18 while confirming the input screen 171, and clicks another item of shooting order information different from the shooting order information selected in step S <b> 23. Here, it is assumed that the item of the imaging order information whose “imaging order ID” P1 is “002” is clicked.

  Upon receiving an input from the input operation unit 18, the control unit 14 of the console 7 captures the imaging order information whose “imaging order ID” P <b> 1 is “002” among the plurality of imaging order information stored in the storage unit 21. Are additionally selected (step S28). Then, the imaging order information selected in step 28 and the console ID of the console 7 are transmitted to the radiation image detection apparatus 6 (step S29).

  When receiving the imaging order information and the console ID from the console 7, the control unit 60 of the radiological image detection apparatus 6 receives “imaging order information” and the “patient ID” included in the imaging order information stored in the RAM 82 in step S25. It is determined whether or not P2 is the same (step S30; determination means). Here, since each “patient ID” P2 is “100085” and the same (step S31: Yes), the additional selection of the received imaging order information is permitted, and the imaging order information is stored in the RAM 82 (step S32; Permission means). Then, a response signal indicating the discrimination result is transmitted to the console 7 (step S34). In step S28, when the imaging order information with “004” as the “imaging order ID” P1 is selected, the “patient ID” P2 of the imaging order information is “100125” and is not the same ( In step S31: No), the photographing order information is deleted without permitting additional selection (step S33). And the response signal which shows this discrimination | determination result is transmitted to the console 7 (step S34).

  When the control unit 14 of the console 7 receives the response signal from the radiation image detection device 6, the control unit 14 confirms with the operator whether or not to further select other imaging order information (step S35). Furthermore, when other imaging order information is selected (step S35: No), the above-described steps S27 to S34 are repeated. When this selection operation is repeated and the additional selection of imaging order information is completed (step S35: Yes), a selection result screen (not shown) indicating which imaging order information is allowed to be displayed is displayed on the display unit 17. (Step S36), preparation for photographing is completed. Then, the photographing information included in the photographing order information is transmitted to the photographing operation device 4.

  As described above, normally, in one imaging flow, it is more efficient to select a plurality of imaging order information and perform a plurality of radiation imagings collectively. For this reason, also in the present embodiment, as in the first embodiment, all the imaging order information permitted to be selected by the radiological image detection apparatus 6, that is, the “imaging order ID” P1 is “001”, “002”. , It is assumed that three pieces of photographing order information “003” are selected.

  When the above-described preparation for imaging is completed, the operator mounts the selected radiation image detection device 6 on the detection device mounting port 11a of the supine imaging table 11. At this time, the radiation image detection device 6 enters a photographing standby state (step S37). Then, according to the selection order of the radiographing order information selected by the radiographic image detection device 6, the radiographing device 3 is controlled based on the control information from the radiographic image radiographing device 3 by controlling the radiographing operation device 4 based on the radiographing information received from the console 7. Radiation is irradiated.

  The control unit 60 of the radiographic image detection device 6 detects the radiation irradiated from the radiographic image capturing device 3 and transmitted through the patient 12, generates radiographic image data, and stores it in the image storage unit 66 (step S38). Then, the radiation image data and the imaging order information are associated with each other from the generation order in which the radiation image data is generated and the selection order in which the imaging order information is selected (step S39), and this correspondence information is stored in the RAM 82. In the present embodiment, as described above, since three pieces of shooting order information are selected, the operations in step S37 and step S38 are repeated three times. When imaging is completed (step S40: Yes), radiation image data, imaging order information, and correspondence information are transmitted to the console 7 (step S41).

  The control unit 14 of the console 7 receives radiation image data, imaging order information, and correspondence information from the radiation image detection device 6 (step S42) and stores them in the storage unit 21. And based on correspondence information, the confirmation screen (not shown) which shows the state which matched radiographic image data and imaging | photography order information is displayed on the display part 17 (step S43).

  The operator confirms the confirmation screen displayed on the display unit 17, and if there is no error in these correspondences (step S44: Yes), the flow ends. On the other hand, if there is an error in the correspondence (step S44: No), the input operation unit 18 is operated and corrected (step S45). In the present embodiment, only the radiographing order information of the same patient is selected by the radiographic image detection device 6, and radiography is performed based on this radiographing order information. For this reason, the operator can distinguish a plurality of pieces of radiographic image data, and even when the correspondence between the radiographic image data and the imaging order information is incorrect, it can be easily recognized.

  As described above, in the present embodiment, the imaging order information is configured to be transmitted to the radiological image detection apparatus 6, and the radiographic imaging is performed in the order in which the imaging order information is selected (the order in which the imaging order information is transmitted). The imaging order information and the radiation image data can be associated with each other accurately. However, when performing many radiographs at the same time by making the best use of the characteristics of the radiographic image detection device 6, it is difficult for the operator to accurately remember the selection order of a large number of radiographing order information. There is a high possibility that the order of information and the order of radiography will be mistaken. On the other hand, when the radiographic image detection device 6 is provided with a display unit for displaying radiographing order information and configured to perform radiography while confirming radiographing order information displayed on the display unit, the operator can There is no need to memorize shooting order information. However, with this configuration, the radiation image detection device 6 must be provided with a display unit, which makes the device itself expensive and easily damaged.

  Therefore, in the present embodiment, when selecting a plurality of pieces of radiographing order information respectively corresponding to radiographic image data for a plurality of radiographs, the radiographic image detection device 6 uses the “patient ID” P2 of one radiographing order information and the other. It is determined whether or not the “patient ID” P2 of the imaging order information is the same, and only the other imaging order information that is the same is permitted to be additionally selected. Usually, if it is the same patient, the possibility of photographing the same part or a similar part is low.

  For this reason, even if the same patient is imaged multiple times by one radiographic image detection device 6 and the generated radiographic image data for a plurality of radiographs are stored simultaneously, the radiographic image data for the plurality of radiographs is displayed on the console 7. When this is done, the operator can accurately identify which radiation image data corresponds to which radiographing order information. Therefore, even if the radiological image detection device 6 incorrectly associates the radiographic image data with the imaging order information, the operator can easily notice the miscorrelation, and correct this accurately. Therefore, it is possible to prevent the radiation image data from being mixed up. Further, it is not necessary to provide a display unit in the radiation image detection device 6, and it is possible to provide an inexpensive device that is not easily damaged.

  In addition, when selecting radiographing order information, it is not necessary for the doctor himself / herself to select which radiographing order information can identify the radiographic image data, thereby improving work efficiency.

  In the present embodiment, when additional radiographing order information is selected, other radiographing order information is transmitted to the radiological image detection device 6 one by one from the console 7, and the radiographic image detection device 6 transmits other radiographing order information. The imaging order information is determined one by one. However, for example, after the transmission of one radiographing order information, other radiographing order information may be transmitted from the console 7 at a time, and the radiation image detection device 6 may be configured to discriminate these.

  Further, as the imaging order information having a predetermined relationship with the selected one imaging order information, it is set as having the same “patient ID” P2 as the “patient ID” P2 of the selected one imaging order information. Needless to say, the present invention is not limited to this, as in the first embodiment.
