Description

[Technical Field]

[0001] The present invention relates to a report creation device, a report creation system, a report creation method, and a program. [Background technology]

[0002] Conventionally, mammography images are obtained in the medial-lateral oblique (MLO) and cranio-caudal (CC) directions by mammography and are interpreted by a specialist. In mammography, MLO mammography images (MLO images) are generally always obtained, whereas CC mammography images (CC images) may not be obtained in cases such as total mastectomy or breast defect.

[0003] The image reader creates an interpretation report by annotating the position of the lesion on the actual mammography image on the display screen, as described in Patent Document 1. In this case, only the acquired actual image (MLO image and / or CC image) is displayed on the display screen. Alternatively, the radiologist can create an interpretation report by annotating the location of the lesion on a schematic breast image on the display screen. In this case, both the CC schematic image (CC schema image) and the MLO schematic image (MLO schema image) are always displayed on the display screen. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-227207 Summary of the Invention [Problem to be solved by the invention]

[0005] In the case where only the acquired actual image is displayed on the display screen (Case 1), if no mammogram (CC imaging) has been performed to acquire a CC image, only the MLO image is displayed on the display screen. The radiologist creates a radiology report by annotating the MLO image. In other words, the radiology report includes the annotated MLO image. When annotating the location of a lesion on a schematic breast image on the display screen (Case 2), if no mammogram (CC radiography) has been taken to obtain a CC image, both the CC and MLO schema images are displayed on the display screen. The radiologist creates an interpretation report by annotating only the MLO schema image. In other words, the interpretation report contains both the annotated MLO schema image and the unannotated CC schema image.

[0006] In Case 1, when a doctor other than the radiologist checks the radiology report, the doctor can recognize that CC imaging has not been performed because the CC image is not listed in the radiology report. However, in Case 2, when a doctor other than the radiologist checks the radiology report, the doctor cannot tell whether CC photography has not been performed or whether CC photography has been performed but no annotations have been added, because the radiology report contains unannotated CC schema images.

[0007] An object of the present invention is to provide a report creation device, a report creation system, a report creation method, and a program that enable intuitive confirmation of whether CC photography has been performed. [Means for solving the problem]

[0008] In order to solve the above problem, a report creation device includes: A report creation device that displays an MLO schema image and a CC schema image on a display unit, The device is equipped with a display control unit that controls the screen display in a manner that makes it clear that CC photography is not being performed.

[0009] The report creation system is The medical image management device includes the above-mentioned report creation device and a medical image management device that manages medical images, and the medical image management device includes a detection unit that detects the presence or absence of a CC image that is an actual image.

[0010] The method for creating a report is A report creation method using a report creation device that displays an MLO schema image and a CC schema image on a display unit, The method includes a display control step of controlling the display on the screen in a manner that makes it clear that CC photography has not been performed.

[0011] The program also A computer of a report creation device that displays an MLO schema image and a CC schema image on a display unit, It functions as a display control unit that controls the screen display in a manner that makes it clear that CC photography is not being performed. [Effects of the Invention]

[0012] According to the present invention, it is possible to intuitively check whether CC photography has been performed or not. [Brief explanation of the drawings]

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0015] <Configuration of medical image system 100 according to the first embodiment> First, the configuration of a medical image system 100 including a report creation device 2 that is an embodiment of an image processing device of the present invention will be described. FIG. 1 shows the system configuration of a medical image system 100 according to this embodiment. As shown in Fig. 1, the medical image system 100 is configured to include a mammography device 1, a report creation device 2, and a server device 3. These devices 1 to 3 are connected to each other via a communication network N constructed within a medical facility, such as a LAN (Local Area Network), so that they can send and receive data to and from each other. The number of each device is not particularly limited.

[0016] The mammography device 1 is an X-ray imaging device that takes an X-ray of a breast to generate a digital mammography image (mammography image data) and transmits it to the server device 3. The mammography device 1 can externally input various types of information to be added to each generated mammography image, such as patient information and examination information, or can automatically generate the information. Patient information includes patient identification information (e.g., patient ID) for identifying the patient (subject), as well as information such as the patient's name, gender, and date of birth. Examination information includes examination identification information (e.g., examination ID) for identifying the examination, examination date and time, examination conditions (examination site, laterality (left, right)), direction (e.g., craniocaudal (CC) or mediolateral oblique (MLO)), and modality type. In this embodiment, a series of images (two MLO images, one for each side, and one CC image) acquired during a mammography examination of the same patient are assigned the same examination ID and managed accordingly. The mammography device 1 adds the patient information, examination information, and a unique ID (UID) for identifying the image to the generated mammography image as additional information and transmits the resulting image to the server device 3 via the communication network N.

[0017] The report creation device 2 is a computer that allows an image reader to create a report (image interpretation report) by adding annotations to schema images (CC schema images, MLO schema images).

[0018] Fig. 2 shows an example of the functional configuration of the report creation device 2. As shown in Fig. 2, the report creation device 2 is configured to include a control unit 21, an operation unit 22, a display unit 23, a communication unit 24, and a storage unit 25, and each unit is connected by a bus.

[0019] The control unit 21 is configured with a CPU (Central Processing Unit), RAM (Random Access Memory), etc. The CPU of the control unit 21 reads out various programs such as system programs and processing programs stored in the storage unit 25, expands them in the RAM, and executes various processes (such as the report creation process described below) in accordance with the expanded programs. The control unit 21 functions as a display control unit that controls the screen display in a manner that makes it clear that CC photography is not being performed. The control unit 21 functions as a report creation unit that creates an interpretation report indicating that CC imaging has not been performed. The control unit 21 functions as a detection unit that detects the presence or absence of a CC image, which is an actual image.

[0020] The operation unit 22 is configured with a keyboard having character input keys, number input keys, and various function keys, etc., and a pointing device such as a mouse, and outputs press signals of keys pressed on the keyboard and operation signals from the mouse as input signals to the control unit 21.

[0021] The display unit 23 is configured with a monitor such as a CRT (Cathode Ray Tube) or LCD (Liquid Crystal Display), and displays various screens (such as the schematic image display screen described below) in accordance with the instructions of the display signal input from the control unit 21.

[0022] The communication unit 24 is configured by a LAN card or the like, and transmits and receives data to and from external devices connected to the communication network N via a switching hub.

[0023] The storage unit 25 is configured by, for example, an HDD (Hard Disk Drive), a semiconductor nonvolatile memory, etc. The storage unit 25 stores various programs as described above. The storage unit 25 also stores schema images (CC schema images, MLO schema images), etc.

[0024] The server device 3 constitutes a PACS (Picture Archiving and Communication System). The server device 3 comprises a control unit 31, an operation unit 32, a display unit 33, a communication unit 34, a storage unit 35 having an image DB 351, and the like. Details of each component of the server device 3 will be described later. The server device 3 stores and manages mammography images (actual images) generated by the mammography device 1 in the image DB 351 in association with supplementary information (UID, patient information, and examination information) and a schematic image corresponding to the mammography image.

[0025] (Report creation process case 1) Next, the report creation process will be described with reference to FIG. 3 is a flowchart showing the flow of the report creation process executed by the control unit 21 of the report creation device 2. The report creation process is started when the control unit 21 receives instruction information indicating the start of the report creation process input by the radiologist using the operation unit 22.

[0026] First, the control unit 21 causes the display unit 23 to display the schema image display screen D1 shown in FIG. 4, and displays the schema images (CC schema image, MLO schema image) as default (step S1).

[0027] Here, the schematic image display screen D1 shown in FIG. 4 will be described. The area A1 is an area where an MLO schema image is displayed. The radiologist adds annotations to the MLO schema image displayed in the area A1. The area A2 is an area for displaying a CC schema image. The radiologist adds annotations to the CC schema image displayed in the area A2. Button B1 is a button for displaying the screen in a manner that makes it clear that CC photography is not being performed. The manner in which it is clear that CC photography has not been performed is to hide the CC schema image displayed in area A2 or to display information indicating that there is no CC schema image information. The manner in which information indicating that there is no CC schema image information is displayed is, for example, to gray out the CC schema image displayed in area A2 or to display a message such as "No CC photography" on the CC schema image displayed in area A2.

[0028] Next, the control unit 21 determines whether or not a predetermined user operation has been performed (step S2). The predetermined user operation is an operation for changing the schematic image display screen D1 to a state in which it is clear that CC imaging has not been performed. For example, the predetermined user operation is an operation of pressing button B1 on the schematic image display screen D1 shown in FIG. If it is determined that a predetermined user operation has been performed (step S2; YES), the control unit 21 advances the report creation process to step S3. If it is determined that a predetermined user operation has not been performed (step S2; NO), the control unit 21 advances the report creation process to step S4.

[0029] Next, the control unit 21 controls the display unit 23 to display the schematic image display screen D1 shown in FIG. 5, in such a manner that it is clear that CC imaging has not been performed (step S3; display control step).

[0030] Here, the schematic image display screen D1 shown in FIG. 5 will be described. In the area A2, the CC schema image is changed to non-display. The button B2 is a button for redisplaying the CC schema image in the area A2.

[0031] Next, the control unit 21 creates a report (step S4; report creation step) and ends the report creation process. Specifically, the radiologist creates a report by adding annotations to the schematic image displayed on the schematic image display screen D1 using the operation unit 22. Then, the control unit 21 receives a signal indicating completion of report creation from the operation unit 22 and creates report information.

[0032] The report created in this way will be in a form that makes it clear that CC photography has not been performed if CC photography has not been performed, allowing a doctor other than the person reading the image to intuitively confirm that CC photography has not been performed.

[0033] (Report creation process case 2) Next, the report creation process will be described with reference to FIG. In case 2, in addition to case 1, the report creation process is executed starting from the control unit 21 receiving an examination ID input by the radiologist using the operation unit 22. The report creation process shown in Fig. 6 differs from the report creation process shown in Fig. 3 in steps S11 and S12. The other steps have the same processing content as the steps with the same names in Fig. 3.

[0034] First, the control unit 21 detects whether or not there is a CC image, which is an actual image, in the image DB 351 of the server device 3 based on the examination ID (detection result) (step S11; detection step).

[0035] Next, the control unit 21 determines whether or not a CC image is present based on the detection result (step S12). If it is determined that there is a CC image (step S12; YES), the control unit 21 advances the report creation process to step S14. If it is determined that there is no CC image (step S12; NO), the control unit 21 advances the report creation process to step S13.

[0036] In this way, the control unit 21 automatically controls the screen display in a manner that makes it clear that CC imaging has not been performed, thereby preventing the radiologist from forgetting to perform the specified user operation in case 1, resulting in the CC schema image remaining displayed in area A2 even though CC imaging has not been performed. Case 1 and Case 2 may be combined.

[0037] <Configuration of medical image system 100 according to the second embodiment> In the first embodiment, the control unit 21 of the report creation device 2 has the function of a detection unit that detects the presence or absence of a CC image, which is an actual image, but in the second embodiment, the control unit 31 of the server device 3 has the function of a detection unit. The other configurations of the medical image system 100 are the same as those in the first embodiment.

[0038] Fig. 7 shows an example of the functional configuration of the server device 3. As shown in Fig. 7, the server device 3 is configured to include a control unit 31, an operation unit 32, a display unit 33, a communication unit 34, and a storage unit 35, and each unit is connected via a bus.

[0039] The control unit 31 is configured with a CPU (Central Processing Unit), RAM (Random Access Memory), etc. The CPU of the control unit 31 reads out various programs such as system programs and processing programs stored in the storage unit 35, expands them in the RAM, and executes various processes (such as the report creation process described below) in accordance with the expanded programs. The control unit 31 functions as a detection unit that detects the presence or absence of a CC image, which is an actual image.

[0040] The operation unit 32 is configured with a keyboard having character input keys, number input keys, and various function keys, etc., and a pointing device such as a mouse, and outputs press signals of keys pressed on the keyboard and operation signals from the mouse as input signals to the control unit 31.

[0041] The display unit 33 is configured to include a monitor such as a CRT (Cathode Ray Tube) or LCD (Liquid Crystal Display), and displays various screens according to instructions of a display signal input from the control unit 31.

[0042] The communication unit 34 is configured by a LAN card or the like, and transmits and receives data to and from external devices connected to the communication network N via a switching hub.

[0043] The storage unit 35 is configured by, for example, an HDD (Hard Disk Drive), a semiconductor nonvolatile memory, etc. The storage unit 35 stores various programs as described above.

[0044] (Report creation process case 3) Next, the report creation process will be described with reference to FIG. FIG. 8 is a flowchart showing the flow of the report creation process executed by the control unit 21 of the report creation device 2 and the control unit 31 of the server device 3 in cooperation with each other. The report creation process is started when the control unit 21 receives instruction information that indicates the start of the report creation process and is input by the radiologist using the operation unit 22. 8 differs from the report creation process shown in Fig. 6 in steps S21 to S24. The other steps have the same processing content as the steps with the same names in Figs.

[0045] First, the control unit 21 transmits the examination ID input by the image reader using the operation unit 22 to the control unit 31 via the communication network N (step S21).

[0046] Next, the control unit 31 detects whether or not there is a CC image, which is an actual image, in the image DB 351 of the server device 3 based on the examination ID (detection result) (step S22; detection step).

[0047] Next, the control unit 31 transmits the detection result (CC image presence / absence information) to the control unit 21 via the communication network N (step S23).

[0048] Next, the control unit 21 determines whether or not a CC image is present based on the received detection result (step S24). If it is determined that there is a CC image (step S24; YES), the control unit 21 advances the report creation process to step S26. If it is determined that there is no CC image (step S24; NO), the control unit 21 advances the report creation process to step S25.

[0049] In this way, the function of the detection unit that detects the presence or absence of a CC image, which is an actual image, is not limited to being provided in the control unit 21 of the report creation device 2.

[0050] <Effects> As described above, the report creation device 2 is a report creation device that displays an MLO schema image and a CC schema image on a display unit, and is equipped with a display control unit (control unit 21) that controls the screen display in a manner that makes it clear that CC photography has not been performed. This allows you to intuitively check whether CC photography has been performed or not. Specifically, conventionally, an MLO schema image and a CC schema image were always displayed on the screen, and as a result, an MLO schema image and a CC schema image were always included in the created radiology report. According to the present invention, the screen display can be controlled in a manner that makes it clear that CC imaging has not been performed, and as a result, the created radiology report can also reflect a manner that makes it clear that CC imaging has not been performed.

[0051] In addition, the report creation device 2 is equipped with a report creation unit (control unit 21) that creates an interpretation report indicating that CC photography has not been performed when control is performed to indicate that CC photography has not been performed. This makes it possible to intuitively check whether CC imaging was performed when viewing the radiology report.

[0052] In addition, the report creation device 2 is equipped with a detection unit (control unit 21) that detects whether or not a CC image, which is an actual image, is present, and the display control unit (control unit 21) controls the screen display in a manner that makes it clear that CC photography has not been performed, based on the detection results detected by the detection unit. Therefore, even if the image reader forgets to perform the operation, the image is displayed on the screen in an appropriate manner.

[0053] In addition, the report creation system (medical image system 100) includes the above-mentioned report creation device 2 and a medical image management device (server device 3) that manages medical images, and the medical image management device (server device 3) includes a detection unit. Therefore, even if the image reader forgets to perform the operation, the image is displayed on the screen in an appropriate manner.

[0054] In addition, the report creation method is a report creation method by a report creation device 2 that displays an MLO schema image and a CC schema image on a display unit, and includes a display control step (steps S3, S13, and S25) that controls the screen display in a manner that makes it clear that CC photography has not been performed. This allows you to intuitively check whether CC photography has been performed or not.

[0055] The program also causes the computer of the report creation device 2, which displays the MLO schema image and the CC schema image on the display unit, to function as a display control unit (control unit 21) that controls the screen display in a manner that makes it clear that CC photography has not been performed. This allows you to intuitively check whether CC photography has been performed or not.

[0056] Although the embodiment of the present invention has been described above, the description of the above embodiment is a preferred example of the present invention, and the present invention is not limited to this.

[0057] In the above description, examples have been disclosed in which a hard disk or a semiconductor nonvolatile memory is used as a computer-readable medium for the program according to the present invention, but the present invention is not limited to these examples. Portable recording media such as CD-ROMs can also be used as other computer-readable media. Furthermore, carrier waves can also be used as a medium for providing the program data according to the present invention via a communication line.

[0058] In addition, the detailed configuration and detailed operation of each device constituting the medical image system can be modified as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
