  By the way, it is also conceivable that an additional imaging instruction for a certain examination is not limited to an engineer operating the imaging apparatus, but may be performed by, for example, a doctor who observes a medical image obtained by such an imaging apparatus with an external apparatus. However, in Patent Literature 1, when an instruction for additional imaging is given from an external device as described above, it is not considered to appropriately manage the state of an inspection in which such additional imaging is instructed.

  The control device according to the present invention includes a communication unit that transmits and receives examination information for taking a medical image, and information indicating the state of the examination, in a state where photographing of the medical image included in the examination is completed. Exam editing means for adding any information of information indicating a complete state and information indicating an incomplete state in which imaging of a medical image included in the test is not completed to the information of the test The inspection editing means has information indicating that the examination is incomplete when the communication means receives a notification for re-imaging the medical image included in the examination. Is added to the information of the inspection.

  According to the present invention, when an instruction for re-imaging is received after obtaining a medical image, the examination related to re-imaging is changed from a completed state to an incomplete state. You can know if the inspection needs to be taken. Therefore, management related to re-shooting can be performed more accurately.

  In a medical facility, an information system connected via a network is constructed. For example, when a doctor determines that X-ray imaging is necessary, the doctor inputs an examination instruction from a HIS (Hospital Information System) terminal or a RIS (Radiology Information System) terminal included in the information system. The HIS is a system that comprehensively manages medical information including patient information and examinations for taking medical images. The RIS is a system that manages the order of radiography. The contents of the inspection instruction are transmitted to the requested department through the information system. The requested department is, for example, a radiation department that takes a radiographic image that is an example of a medical image.

  Request information transmitted by HIS or RIS is called an inspection order. The examination order includes the department name of the requester, examination items, patient personal data, and the like. In the radiation department, the radiographic image capturing system receives an inspection order and acquires an imaging protocol necessary for the inspection. An engineer who takes a radiographic image may input an imaging protocol to the imaging system. The inspection proceeds based on the inspection order. An inspection order may include multiple imaging protocols. Here, the imaging protocol includes an imaging region requested by a doctor, an imaging method, information on image processing, and the like. An image obtained by photographing is transferred to, for example, an image detecting device (hereinafter referred to as an image detecting device).

  The image inspection apparatus displays the transferred captured image on the screen. The imaging device is, for example, a workstation. An engineer or a doctor looks at the image displayed on the imaging apparatus and determines whether the quality is suitable for interpretation. Interpretation means observing a medical image and diagnosing the subject of the medical image. When it is determined that the captured image is suitable for interpretation, the captured image is transferred to and saved in PACS (Picture Archiving and Communication Systems). PACS is a medical image management system that holds radiographic images and images obtained by other medical imaging apparatuses. On the other hand, when it is determined that the captured image is not suitable for interpretation, the engineer performs re-imaging. At this time, if it is determined that the photographed image has failed to be photographed and is not suitable for interpretation (hereinafter referred to as “failure”), re-photographing is performed based on the same photographing condition as the photographed image or changed photographing conditions. For example, in the case of taking an X-ray image, the following cases may be cited when it is determined that the image is damaged. First, there is a case where the dose of radiation to the subject is insufficient (insufficient dose) or excessive (excess dose). In addition, there is a case where the setting of the aperture that determines the region to be irradiated with X-rays is inappropriate (aperture error). In addition, the subject may have moved during the photographing (patient movement). In addition, there is a case where a part to be photographed is wrong (difference in photographing part) or a different subject is photographed (different patient).

  An object of the control device according to the embodiment of the present invention is to accurately perform a re-imaging preparation operation when receiving an instruction for re-imaging from an external terminal such as an imaging device. Hereinafter, embodiments of the present invention will be described. Here, a case where a radiographic image is captured by digital X-ray imaging will be described as an example of a medical image. The medical image is not limited to this, and may be an image taken by a technique such as computer tomography, nuclear magnetic resonance imaging, or positron emission tomography.

[First embodiment]
Based on FIG. 1, an information system including a control device according to a first embodiment of the present invention will be described. In the information system, for example, a control device 102, an image generation device 103, an RIS 104, a radiation generation device 105, a PACS 106, and an imaging device 107 are connected by a network 101. The control device 102, the image generation device 103, and the radiation generation device 105 correspond to the medical image photographing device according to the embodiment of the present invention. The image generation device 103 is, for example, an FPD (Flat Panel Detector). The radiation generator 105 is, for example, an X-ray source (not shown) and a high-pressure generator (not shown) for causing the X-ray source to generate X-rays. The PACS 106 includes a storage unit (not shown) that stores medical images and incidental information such as imaging conditions of such medical images and patient information, and a controller (not shown) that manages information stored in the storage unit. Details will be described below.

  The control device 102 acquires an inspection order from the RIS 104. The control device 102 reads out imaging conditions based on the examination order acquired from the RIS 104 and controls the image generation device 103. The FPD, which is an example of the image generation device 103, prepares to receive radiation based on imaging conditions controlled by the control device 102.

  The control device 102 controls the radiation generation device 105. The radiation generator 105 prepares to generate X-rays on an X-ray source (not shown) based on the imaging conditions controlled by the control device 102. A high-pressure generator (not shown) of the radiation generator 105 applies a high-pressure pulse to an X-ray source (not shown) when a user presses an exposure switch (not shown), and an object is placed from the X-ray source (not shown). X-rays are exposed to the area that is covered. X-rays that have passed through the subject or passed around the subject are incident on an FPD that is an example of the image generation device 103.

  The image generation device 103 generates a radiation image based on the radiation generated by the radiation generation device 105 and transmits the generated radiation image to the control device 102. The image generation apparatus 103 is controlled by the control apparatus 102, converts incident X-rays into electric signals, and then transmits them to the control apparatus 102 as digital images. For example, an FPD, which is an example of the image generation device 103, converts incident X-rays into visible light by a phosphor (not shown), which is detected by a photodiode (not shown), and an A / D converter (not shown). To an electrical signal. Alternatively, the FPD converts X-rays into electrical signals using amorphous selenium (not shown). The pixel value of the radiation image is obtained by an output from a radiation detection element (not shown) constituting the FPD. The radiation detection element (not shown) includes, for example, a phosphor (not shown) and a photodiode (not shown). In another example, it is composed of amorphous selenium (not shown).

  The control device 102 attaches the imaging condition, patient information, etc. of the imaging to the captured radiographic image. For example, information is attached according to the DICOM (Digital Imaging and Communications in Medicine) standard, and a DICOM image file including information such as radiographic image data, patient information, and imaging conditions is generated. In addition, the control device 102 transmits the captured radiographic image or DICOM image file to the PACS 106.

  Each device included in the information system only needs to be connected to each other via the network 101, and can be remotely installed.

  Next, the configuration of the control device according to the first embodiment will be described in detail based on FIG. The control device 102 is, for example, a computer. The control device 102 includes a CPU (Central Processing Unit) 1701 as a main control unit, a RAM (Random Access Memory) 1702 as a storage unit, a ROM (Read Only Memory) 1705, an SSD (Solid State Drive) 1706, and a graphic control unit. A certain GPU (Graphics Processing Unit) 1708, NICs (Network Interface Cards) 1703 and 1704 as communication units, USB (Universal Serial Bus) 1707 as connection units, HDMI (registered trademark) 1701 These are connected via an internal bus so that they can communicate with each other. It is. A CPU 1701 is a control circuit that integrally controls the control device 102 and each unit connected thereto. A RAM 1702 is a memory for storing a program for executing processing in each unit connected to the control device 102 and various parameters used in image processing. The RAM 1702 stores a control program executed by the CPU 1701, and temporarily stores various data when the CPU 1701 executes various controls. The ROM 1705 stores a program and data in which a control procedure by the CPU is stored. The first NIC 1703, which is a communication circuit, is connected to an access point of a facility that performs radiography, for example, and the second NIC 1704 is connected to an access point that relays communication in the information system. The SSD 1706 stores the above-described program, a radiographic image obtained by imaging, incidental information, and other various parameters. The USB 1707 is connected to the operation unit 205. The GPU 1708 is an image processing unit and executes image processing in accordance with control from the CPU 1701. An image obtained as a result of the image processing is output to the display unit 204 via the HDMI (registered trademark) 209 and displayed. The display unit 204 and the operation unit 205 may be integrated as a touch panel monitor.

  FIG. 2 is a block diagram illustrating an example of functions of the control device 102. Since the display unit 204 and the operation unit 205 are the same as those illustrated in FIG. 17, the above description is cited and detailed description is omitted here. The control device 102 includes a communication unit 201, a control unit 202, and a storage unit 203. The communication unit 201 transmits / receives information to / from a terminal outside the control apparatus 102 under the control of the control unit 202. Further, the communication unit 201 outputs information to the control unit 202 based on the received information. The communication unit 201 includes, for example, a NIC 1703 and a NIC 1704 in order to transmit / receive information to / from an external terminal. The control unit 202 controls the control device 102 in an integrated manner. The control unit 202 includes an imaging control unit 2021, an inspection editing unit (change unit) 2022, an inspection search unit 2023, and a display control unit 2024. The storage unit 203 stores information under the control of the control unit 202. The storage unit 203 includes, for example, a RAM 1702, a ROM 1705, and an SSD 1706 for storing information. The storage unit 203 may output and store information in an external storage device (not shown) via the communication unit 201. The control unit 202 is a CPU 1701 in one embodiment. More specifically, for example, the control unit 202 according to the embodiment is realized by the CPU 1701 executing programs stored in the RAM 1702, the ROM 1705, and the SSD 1706. In another embodiment, the control unit 202 is realized by a hardware circuit such as an FPGA (not shown) in addition to the CPU 1701 described above. For example, the control unit 202 includes an FPGA that realizes the function of the imaging control 2021. In this case, the CPU 1701 controls at least one of input, parameter setting, and output reception for the FPGA.

  In another embodiment, the display control unit 2024 is realized by the CPU 1701 and the GPU 1708. At this time, the CPU 1701 instructs the GPU 1708 to display predetermined information on the display unit 204, generates display data for the GPU 1708 to display on the display unit 204, and outputs the display data to the display unit 204. .

  The above-described NIC 1703 and NIC 1704 correspond to the communication unit 204. In other embodiments, the communication unit 204 may be realized by a single NIC.

  In another embodiment, a plurality of CPUs 1701 may be included in the apparatus.

  In the following, the function of each block shown in FIG. 2 and the processing related to radiographic image capture and recaptured image capture will be described with reference to FIGS. 18 and 19. Steps S1801 to S1803, steps S1808, and S1809 shown in FIG. 18 are processes mainly performed by the control apparatus 102. Steps S1804 to S1807 illustrated in FIG. 18 are processes mainly performed by the image detection device 107, for example. FIG. 19 shows an example of a screen displayed on the display unit (not shown) of the image inspection apparatus 107.

  In step S <b> 1801, the communication unit 201 acquires an inspection order from the HIS (not shown) or the RIS 104 and inputs it to the control unit 202. The imaging control unit 2021 acquires an imaging protocol based on the inspection order input from the communication unit 201. The shooting control unit 2021 may acquire a shooting protocol input by the user via the operation unit 205. The control unit 202 outputs the inspection order to the storage unit 203, and the storage unit 203 stores the inspection order.

  In step S1802, the imaging control unit 2021 controls radiographic imaging via the communication unit 201 based on the examination order and the imaging protocol. The imaging control unit 2021 controls the radiation generation apparatus 105 and the image generation apparatus 103 to acquire radiation image data. The acquired radiation image data is input to the control device 102 via the communication unit 201. The control unit 202 performs image processing on the received radiographic image and outputs the processed image to the display unit 204. The display unit 204 displays the radiation image output from the control unit 202. In accordance with the DICOM standard, the control unit 202 attaches information included in the examination order or imaging protocol to the radiation image.

  The inspection editing unit (changing unit) 2022 notifies the storage unit 203 of the inspection result information attached to the radiographic image after the control device 102 receives the radiographic image captured based on the imaging protocol.

  The storage unit 203 stores inspection result information. The inspection result information will be described in detail later with reference to FIGS.

  Moreover, the control apparatus 102 acquires the identification information for specifying a radiographic image uniquely. The identification information for uniquely specifying the radiation image is, for example, an image ID uniquely assigned to the radiation image. As the image ID, for example, the control unit 202 assigns an ID of an image shot by the shooting protocol when the shooting protocol is acquired. Alternatively, when the image generation apparatus 103 assigns an image ID to each captured image and transmits the radiation image to the control apparatus 102, the image ID is transmitted in association with the radiation image. The examination editing unit (changing unit) 2022 gives the identification information of the radiographic image to the examination result information of the radiographic image. The identification information may be held in the DICOM tag of each radiation image.

  In step S <b> 1803, the control device 102 outputs the radiation image to the image inspection device 107. The control device 102 associates identification information for specifying the radiographic image and outputs the identification information to the imaging device 107. Here, it is assumed that examination result information including identification information of the radiation image and information related to the imaging protocol is output to the imaging apparatus 107.

  In step S1804, the image inspection apparatus 107 displays the received radiation image on a display unit (not shown) of the image detection apparatus 107. The configuration of the imaging device 107 is the same as that shown in FIG. 17, for example. A user can observe a radiographic image in the imaging apparatus 107 and perform image processing. FIG. 19A shows an example of a screen displayed on the display unit (not shown) of the image detection apparatus 107. In FIG. 19A, a radiation image 1904 and a radiation image 1905, which are two radiation images received from the control apparatus 102, are displayed. A thumbnail image 1902 and a thumbnail image 1903 are displayed in the thumbnail image display area 1901. A thumbnail image 1902 is a reduced image of the radiation image 1904. A thumbnail image 1903 is a reduced image of the radiation image 1905. An area 1906 is an area for displaying patient information. An area 1907 is an area for displaying an imaging protocol for the displayed radiation image. An area 1908 displays the contents described in the DICOM tag when the displayed radiation image is a DICOM format file. The areas 1906 to 1908 are folded for screen efficiency, and detailed information can be displayed by a user operation input. An icon 1909 is an icon for performing an operation input instructing to transfer the selected radiation image to the PACS 106. The icon 1910 is an icon for performing an operation input that instructs re-imaging of the selected radiation image. The icon 1911 is an icon for performing an operation input for ending the image inspection. When an operation input is performed on the icon 1911 and the image inspection is completed, all the displayed radiographic images may be transferred to the PACS 106.

  If the user determines that the radiographic image displayed on the imaging apparatus 107 is an image suitable for interpretation, the process advances to step S1805. The user transfers an image suitable for interpretation to the PACS 106. For example, assume that the user determines that the radiation image 1904 shown in FIG. 19A is suitable for interpretation. The user selects the radiation image 1904 and inputs an operation to the icon 1909. Thereby, the image inspection apparatus 107 determines that the user has determined that the radiation image is an image suitable for interpretation. The imaging device 107 transmits identification information for specifying the radiation image 1904 and information indicating that the radiation image is an image suitable for interpretation to the control device 102. More specifically, the availability information is set as the availability information of the imaging data attached to the examination result information of the radiation image 1904 by the processing in step S1805. In step S 1807, the image inspection apparatus 107 transmits the inspection result information to the control apparatus 102. The imaging data incidental to the inspection result information will be described in detail later with reference to FIGS.

  If the user determines that the radiographic image displayed on the imaging device 107 is a failed image that has failed to be captured, the process advances to step S1806. The image inspection device 107 transmits information for instructing the radiographing of the radiographic image to the control device 102. For example, assume that the user determines that the radiation image 1905 shown in FIG. 19A is a failed image that is unsuitable for interpretation and failed to be captured. When the user selects the radiation image 1905, for example, a frame 1912 shown in FIG. 19B is displayed. When an operation input is performed on the icon 1910 with the radiation image 1905 selected, the imaging apparatus 107 determines that the radiation image 1905 is a failed image. At this time, a list 1913 for inputting the reason for determining that the radiation image 1905 is a failed image is displayed on the screen of the display unit (not shown) of the image inspection apparatus 107. For example, the user selects “patient movement” as the reason for the image loss. When the reason for the imaging failure is input, the imaging apparatus 107 transmits information for instructing the radiographing of the radiation image 1905 to the control apparatus 102. The image inspection apparatus 107 transmits identification information for specifying the radiographic image 1905 and information indicating that the radiographic image is a failed image that is not suitable for interpretation to the control apparatus 102. Specifically, by the processing in step S1806, unusable information is set as the usability information of imaging data attached to the examination result information of the radiation image 1905. In step S 1807, the image inspection apparatus 107 transmits the inspection result information to the control apparatus 102. Then, the process proceeds to step S1807.

  FIG. 19C shows another example of the screen of the display unit (not shown) of the imaging device 107 in steps S1804 to S1806. The icon 1914 is an icon for inputting that the selected radiation image is a failed image. After the user inputs the reason for the copying failure, a screen for inputting whether or not to perform re-shooting as shown in an area 1915 may be displayed. Further, the image inspection device 107 may transmit the reason for the failure of the failed image to the control device 102 together with the information for instructing the re-imaging of the failed image.

  In step S <b> 1808, the communication unit 201 of the control apparatus 102 receives inspection result information from the image inspection apparatus 107. That is, the control apparatus 102 acquires identification information for uniquely specifying a radiographic image and information indicating whether or not the radiographic image is a failed image that has failed to be captured. Specifically, the availability information of the imaging data attached to the inspection result information is acquired. If the availability information is “unusable”, the process advances to step S1809. In step S1809, the radiographic image is re-photographed to newly acquire a radiographic image. That is, when the communication unit 201 receives the identification information of the radiographic image and the information indicating that the radiographic image is defective, the control unit 202 determines that the instruction is to re-image the radiographic image. The communication unit 201 inputs the identification information of the radiographic image and information indicating that the radiographic image is unsatisfactory to the control unit 202 as a re-imaging instruction. The examination search unit 2023 searches the storage unit 203 for examination information including imaging of the failed image based on the identification information of the radiographic image notified as a failed image. If the examination information including the photograph of the failed image is stored in the storage unit 203, the examination editing unit 2022 sets the state of the examination including the photograph of the failed image to an incomplete state. In other words, the inspection editing unit 2022 gives information indicating that the inspection is in an incomplete state to information on the inspection including photographing of the failed image. The inspection editing unit 2022 gives information indicating that the failed image is unusable to the inspection information stored in the storage unit 203. Also, the imaging control unit 2021 acquires a re-imaging imaging protocol based on the search result by the examination search unit 2023. The imaging control unit 2021 performs re-imaging by controlling the image generation device 103 and the radiation generation device 105 based on a re-imaging imaging protocol. Detailed processing of re-photographing will be described in detail later with reference to FIGS. When re-imaging is performed and a radiographic image is acquired, the flow illustrated in FIG. 19 ends.

  If it is determined in step S1808 that the imaging data availability information attached to the examination result information received by the control apparatus 102 is “usable”, the flow illustrated in FIG. 19 ends. The examination editing unit 2022 gives information indicating that the radiation image is usable to the examination information stored in the storage unit 203.

  Next, the inspection result information will be described with reference to FIGS.

  Next, processing relating to re-imaging of a radiation image in the first embodiment will be described with reference to FIG. FIG. 9 is a flowchart illustrating the process according to the first embodiment. Re-imaging when the control apparatus 102 receives a re-imaging instruction for a certain radiation image will be described.

  In step S <b> 901, the control apparatus 102 receives information for instructing re-imaging for a certain radiographic image from the external imaging apparatus 107 via the communication unit 201. When receiving the identification information for specifying the radiographic image and the information indicating that the radiographic image is a failed image, the communication unit 201 determines that it is a re-imaging instruction for the radiographic image. The information related to the re-imaging instruction only needs to include identification information for specifying the radiographic image and information indicating that the radiographic image is a failed image. For example, it is inspection result information accompanied with information on availability or imaging data. In the first embodiment, a case will be described as an example in which inspection result information to which information indicating whether or not the radiographic image received from the control apparatus 102 is used is output to the control apparatus 102. The image inspection apparatus 107 receives inspection data as shown in FIG. 20A from the control apparatus 102, and causes the display unit (not shown) to display radiographic images included in the imaging data 2004 and the imaging data 2005. For example, the radiographic image included in the imaging data 2004 is a radiographic image 1904 shown in FIG. For example, the radiographic image included in the imaging data 2005 is the radiographic image 1905 shown in FIG. 19, and FIG. 20B is the imaging data 2005. As described above with reference to FIG. 19B, it is assumed that the user determines that the radiation image 1905 is a failed image and instructs re-imaging. The image inspection apparatus 107 gives information indicating whether or not the image data 2005 including the radiation image 1905 can be used. As shown in FIG. 21B, the imaging data 2100 is obtained by adding availability 2101 to imaging data 2005 including a radiation image 1905. The image inspection device 107 outputs inspection result information 2102 having the imaging data 2100 to the control device 102. The control device 102 outputs the availability tag to the image detection device 107 as a blank state, and the image detection device 107 sets “usable” or “unusable” information in the availability tag, The data may be output to 102.

  In step S902, the control apparatus 102 searches the storage unit 203 for examination information including radiographic image imaging instructed to perform reimaging, based on the reimaging instruction information received in step S901. The inspection search unit 2023 searches the inspection result information stored in the storage unit 203 based on the received inspection result information. As a result of the search, if there is examination information about the radiographic image instructed to be re-imaged, the process proceeds to step S903, and if not, the process proceeds to step S904. The examination search unit 2023 searches based on the identification information for specifying the radiographic image whether the examination information having the radiographic image is stored in the storage unit 203. Here, the examination search unit 2023 can search using various types of information included in the examination result information 2102 output from the imaging apparatus 107 as keys.

  In step S903, the examination editing unit (changing unit) 2022 indicates that the examination state is in a completed state when the communication unit 204 receives a notification instructing additional photographing regarding photographing included in the examination from an external device. In this case, the state of the inspection is changed to an incomplete state. Here, the completed state is a state in which all of the medical images included in the examination are completed, and the incomplete state is a state in which the imaging of the medical images included in the inspection is not completed. As a specific process, for example, the examination editing unit (changing unit) 2022 gives information indicating that the examination is incomplete to the examination information obtained by searching in step S902. Here, as a result of the search by the examination search unit 2023, if there is examination result information regarding the radiographic image for which re-imaging is instructed, the examination implementation status of the examination result information is not completed. Further, the examination editing unit (changing unit) 2022 may further add information for performing re-imaging of the radiation image to the examination information obtained by the examination retrieval unit 2023. That is, an imaging protocol for re-imaging the failed image instructed to re-image is added to the inspection result information including the imaging data of the failed image. Further, the inspection editing unit (changing unit) 2022 assigns unusable information to the shooting data of the failed image instructed to re-shoot. When the reason for the failure is output from the image inspection apparatus 107, the inspection editing unit (change unit) 2022 gives information indicating the reason for the failure to the shooting data of the failed image. You may make it output the information which shows that the test | inspection including imaging | photography of the said failure image is incomplete to RIS104 or PACS106. Thereby, it is possible to prevent a failed image instructed to be re-photographed from being used for diagnosis.

  In step S904, the imaging control unit 2021 newly acquires an inspection order based on the information on the reimaging instruction received in step S901. For example, the imaging control unit 2021 can acquire the inspection order based on the imaging protocol information included in the received inspection result information.

  Next, FIGS. 10 to 13 illustrate screens displayed on the display unit 204 of the control apparatus 102 at the time of re-shooting in the first embodiment. The display control unit 2024 causes the display unit 204 to display inspection result information. FIG. 10 is an example of a screen displayed on the display unit 204 before receiving information on a re-shooting instruction. An area 1001 shows the entire screen for displaying inspection result information. A table 10011 is a list display in which the inspection order and the inspection result information are combined. A table 10012 is a list display of imaging data and imaging protocols attached to the inspection order and inspection result information displayed in the table 10011. For example, an inspection order 1002 and inspection result information 1003 are displayed on the screen shown in FIG. The display control unit 2024 displays the inspection order subjected to the inspection by replacing it with the inspection result information. The inspection order 1002 has not been inspected. The imaging data 1004 displayed in the table 10012 is imaging data attached to the inspection result information 1003 displayed after the inspection is performed. The imaging data 1004 indicates that the imaging data 1004 is data acquired by the imaging protocol for the front of the chest, as indicated by the part information.

  FIG. 11 is a diagram illustrating a screen displayed on display unit 204 in step S903 shown in FIG. When information for instructing re-imaging is input from the communication unit 201, the examination search unit 2023 searches the storage unit 203 for corresponding examination result information. For example, it is assumed that the inspection result information 1101 illustrated in FIG. 11 is detected as inspection result information corresponding to a re-imaging instruction as a result of the search. In step S <b> 903, the display control unit 2024 causes the display unit 204 to display information indicating that the examination is incomplete in the examination information corresponding to the re-imaging instruction. As a result, “not yet” is displayed as inspection execution information in the inspection result information 1101. “Completed” is displayed as the inspection execution information of the inspection result information whose inspection is completed. In the inspection execution information, “incomplete” may be displayed for information that has not been inspected, and “completed” may be displayed for information that has been inspected. Furthermore, the display control unit 2024 displays the table 10012 displayed on the screen of the display unit 204 by adding a shooting protocol 1102 for re-shooting.

  The control device 102 may display the information on the examination for which the re-imaging instruction has been given separately from the information on the examination without the re-imaging instruction. Thereby, the user can easily know the information of the examination for which the re-imaging instruction has been given. For example, the display control unit 2024 displays the inspection result information for which the re-imaging instruction has been given at the top of the list shown in the table 10011 of FIG. Alternatively, the display control unit 2024 displays the inspection result information for which the re-imaging instruction has been given in a color different from other inspection result information. If the display result information is displayed on the screen as shown in the table 10011, the display control unit 2024 displays the character color, the background color of the table, and the frame color of the inspection result information for which the re-imaging instruction has been given. Is displayed in a color different from that of other inspection result information.

  Further, the control device 102 may display information indicating that the image is a failed image with respect to radiographed image data determined to be a failed image. For example, as shown in the shooting data 1201 shown in FIG. 12, the display control unit 2024 displays the shooting status on the screen of the display unit 204 as “shooting failure”. Change to display. Further, the control unit 202 displays the shooting data 1201 and the shooting protocol 1102 side by side in the table 10012 so that the correspondence between the shooting protocol 1102 added for the re-shooting and the shooting data 1201 including the failed image can be understood. Also good. In another example, the display control unit 2024 causes the display unit 204 to display a dialog indicating that a shooting protocol for re-shooting has been added. In another example, the display control unit 2024 causes the display unit 204 to display the added imaging protocol by blinking or changing the color so that the imaging protocol is distinguished from other imaging protocols and imaging data. As a result, the user can easily know that a photographing protocol for re-photographing has been added.

  FIG. 13 illustrates an example of a screen displayed on the display unit 204 when the process proceeds from step S901 and step S902 to step S904 in the state of FIG. This is a case where the communication unit 201 has received information instructing re-imaging from the image inspection apparatus 107, but inspection result information corresponding to the re-imaging instruction has not been found by the search of the inspection search unit 2023. In this case, the imaging control unit 2021 creates a new inspection order, and the display control unit 2024 adds the inspection order 1301 to the table 10011 shown in FIG. In addition, the display control unit 2024 adds the imaging protocol 1302 attached to the new inspection order 1301 to the table 10012 and causes the display unit 204 to display the imaging protocol 1302.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. Also in the second embodiment, the control device 102 receives the identification information for specifying the radiographic image from the imaging device 107 and the information indicating that the radiographic image is a failed image, thereby performing re-imaging. I do. In the first embodiment, the case where the inspection result information is received from the image inspection apparatus 107 has been described. In the second embodiment, the case where the inspection order is acquired from the image inspection apparatus 107 will be described.

  In step S <b> 1401, the control apparatus 102 acquires an inspection order from the image inspection apparatus 107 via the communication unit 201.

  In step S1402, the control apparatus 102 searches the storage unit 203 for the inspection result information, the inspection order, and the imaging order corresponding to the inspection order acquired in step S1401 from the storage unit 203. If a search result corresponding to the acquired inspection order is obtained, the process proceeds to step S1403. If a search result corresponding to the acquired examination order is not obtained, the process shown in FIG. 14 is terminated. The examination search unit 2023 performs a search using various information included in the examination order acquired in step S1401 as a key. As the imaging order searched by the examination search unit 2023, for example, among the new examination orders acquired in step S904, an imaging protocol corresponding to the imaging protocol attached to the inspection order acquired in step S1401 may be detected as a search result. Further, even if the inspection result information attached to the imaging protocol attached to the inspection order acquired in step S1401 among the inspection result information acquired by the inspection order acquired in step S904 is detected as a search result. Good. The control apparatus 102 may provide the inspection search unit 2023 with a criterion for excluding it from the search target. The exclusion criterion can be arbitrarily set by the user. For example, it is assumed that an imaging protocol for performing imaging under the same conditions as the imaging protocol attached to the inspection order acquired in step S1401 is stored in the storage unit 203. At this time, the examination search unit 2023 does not extract, as a search result, an imaging protocol in which imaging was performed before the period set as the exclusion criterion and information including the imaging protocol. Furthermore, even if an inspection result or inspection order comes with an equivalent to the imaging protocol, the shooting date or inspection date incidental to the inspection result or inspection order is free for any time from the date the inspection order was acquired, etc. A criterion for excluding search may be provided.

  In step S1403, the inspection order information acquired in step S1401 is reflected on the inspection result information or inspection order searched in step S1402. For example, an imaging protocol incidental to the acquired inspection order may be added to the searched inspection result information or inspection order. If the imaging protocol attached to the acquired examination order is equivalent to the imaging protocol attached to the searched examination order, the imaging protocol attached to the acquired examination order may not be added. Furthermore, when the imaging protocol attached to the acquired examination order is equivalent to the imaging protocol of the imaging data attached to the retrieved examination result information, the imaging protocol attached to the acquired examination order may not be added. Although only the shooting protocol is mentioned here, it is not necessary to limit to this.

In step S1402, the inspection search unit 2023 searches the storage unit 203 for inspection result information corresponding to the received inspection order, and detects inspection result information 1502 shown in FIG. 15 as the corresponding inspection result information. In step S1403, the inspection editing unit 2022 edits the inspection result information 1502 detected in step S1402. The examination order 1601 shown in FIG. 16 is obtained by integrating examination result information having the same patient information ID with the examination order received in step S1402. Specifically, the imaging control unit 2021 acquires an examination order in which the patient ID is 5, the patient name is EEE, and the imaging protocol is the front of the abdomen. The examination search unit 2023 searches the storage unit 203 using the patient ID of the examination order as a key, and detects corresponding examination result information 1502. The imaging control unit 2021 acquires the inspection order 1601 by integrating the inspection date and the imaging data of the inspection result information 1502. The examination order 1601 shown in FIG. 16 has the examination date and patient name of the examination result information 1502 shown in FIG. 15, and indicates that an imaging protocol that has not been photographed is included.
