Description

[Technical field]

[0001] The embodiments disclosed in this specification and the drawings relate to a medical information display device and a medical information display system. [Background technology]

[0002] Conventionally, there is a worklist that displays a list of the order of examinations in which image diagnosis is performed by a radiologist. The radiologist inputs an instruction for displaying the examination from the displayed worklist. At this time, medical images related to the specified examination are displayed in a viewer, and an input screen for an image interpretation report related to the specified examination is displayed on an image interpretation terminal. The radiologist performs image interpretation on the displayed medical images, and writes a diagnosis result (e.g., findings, impressions, etc.) in the image interpretation report. For example, when an urgent image interpretation occurs, such as an acute case, a mark indicating the urgent state is displayed on the worklist. At this time, the radiologist gives priority to reading the examination marked as urgent. In addition, an application that creates an image interpretation report has a function (hereinafter referred to as a sequential display function) that displays an input screen for an image interpretation report corresponding to the next examination in the worklist when input of the image interpretation report is completed on the input screen for the image interpretation report related to the examination selected in the worklist.

[0003] In recent years, advances in image processing technology for medical images have made it possible to detect abnormalities in medical images, for example, through computer-aided diagnosis (hereinafter referred to as CAD). Analysis results of medical images using CAD and other methods include abnormalities related to acute diseases, such as acute appendicitis, acute myocardial infarction, and cerebral infarction. Acute diseases are abnormalities that require urgent medical treatment. Radiologists need to give priority to reading medical images in which acute diseases are detected in the analysis results, but the sequential display function does not take into account the analysis results, and therefore has a problem in that the input screen for the reading report, which should be displayed next as a priority, is not displayed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The medical information display device and the medical information display system will be described in detail below with reference to the drawings. In the following embodiments, parts with the same reference numerals perform the same operations, and redundant descriptions will be omitted as appropriate. Note that the medical information display device and the medical information display system according to the present application are not limited to the following embodiments.

[0009] (Embodiment) The overall configuration of a medical information display system according to an embodiment will be described. FIG. 1 is a diagram showing an example of the configuration of a medical information display system 1 according to an embodiment. The medical information display system 1 has an electronic medical record server device 3, a radiology department information server device 5, a medical image diagnostic device 7, a medical image management server device 9, a medical information processing device 11, and a medical information display device 20. The medical information processing device 11 may be realized as a server device. The medical information display system may have a configuration including the medical information processing device 11 and the medical information display device 20, as shown in a dotted frame 2 in FIG. 1.

[0010] The electronic medical record server device 3 and a terminal device (hereinafter referred to as an electronic medical record terminal device) electrically connected to the electronic medical record server device 3 constitute an electronic medical record system. The electronic medical record system is an information system that manages electronic medical records for recording medical treatment details. The electronic medical record server device 3 is a computer device that executes processes related to the management of electronic medical records. The electronic medical record terminal device is used by doctors, nurses, etc. who input and refer to electronic medical records. The electronic medical record server device 3 and the electronic medical record terminal device are connected to a communication network.

[0011] The electronic medical record terminal device inputs an examination order for a subject according to the instruction of a clinician. When the examination order is for imaging of the subject for image diagnosis, the examination order includes, for example, the examination area, the examination type (information on the examination content such as modality), the name of the disease (hereinafter referred to as the disease name), the purpose of the examination, etc. The examination order may also include information such as the patient ID, patient name, examination ID, and examination date of the subject undergoing the examination. In response to the input of the examination order, the electronic medical record server device 3 transmits the examination order to the radiology department information server device 5 together with the patient information of the subject, etc.

[0012] The radiology department information server device 5 and the terminal devices (hereinafter referred to as radiology department terminal devices) electrically connected to the radiology department information server device 5 constitute a radiology department information system (hereinafter referred to as a RIS (Radiology Information Systems)). The RIS is an information system that manages information in the radiology department in the hospital. The radiology department information server device (hereinafter referred to as a RIS server) 5 is a computer device that executes processes related to the management of information in the radiology department.

[0013] As an example of the operation, the RIS server 5 receives an examination order from the electronic medical record server device 3, and acquires information (e.g., examination type) related to the medical image diagnostic device 7 from the examination order. The RIS server 5 transmits the examination order to the medical image diagnostic device 7 specified by the examination order. When the examination order is transmitted to the medical image diagnostic device 7, the RIS server 5 may add information such as a patient ID and an examination date to a DICOM (Digital Imaging and Communications in Medicine) tag or the like.

[0014] The medical image diagnostic device 7 is a device for acquiring medical images, such as an X-ray diagnostic device, an X-ray computed tomography (CT) device, and a magnetic resonance imaging (MRI) device. The medical image diagnostic device 7 performs imaging of the subject in response to an operation to start imaging by a technician or the like based on an examination order from the RIS server 5. By performing imaging, the medical image diagnostic device 7 collects data indicating the state of the subject's internal tissues. The medical image diagnostic device 7 generates a medical image based on the data. The medical image diagnostic device 7 assigns an examination ID to the generated medical image. The medical image diagnostic device 7 transmits the generated medical image to the medical image management server device 9 together with the examination order. The medical image diagnostic device 7 may transmit the generated medical image to the medical information processing device 11 in addition to the medical image management server device 9.

[0015] The medical image management server device 9 and a terminal device (hereinafter referred to as an image management terminal device) electrically connected to the medical image management server device 9 constitute a medical image management system (hereinafter referred to as a PACS (Picture Archiving and Communication Systems)). PACS is an information system that manages medical images such as X-ray CT images and MR images, and interpretation reports also called image diagnosis reports. The medical image management server device (hereinafter referred to as a PACS server) 9 is a computer device that executes processes related to the management of medical images.

[0016] When the PACS server 9 receives the medical image and the examination order from the medical image diagnostic device 7, it stores the medical image and the examination order in association with each other. At this time, the PACS server 9 transmits the medical image and the examination order to the medical information processing device 11. Note that DICOM meta information (hereinafter referred to as additional information) is added to the medical image. The additional information includes the patient name, the patient ID, a description of the medical image (e.g., slice thickness, slice number, presence or absence of contrast, etc.), an examination ID, etc.

[0017] The medical image management server device 9 may be used as a medical information management device that realizes a vendor neutral archive (VNA). The VNA is an information technology platform that can independently store medical image examination results and other patient data from multiple vendors' PACS in a long-term, standardized, and centralized manner.

[0018] The medical information processing device 11 includes a first communication interface 13, a first memory 15, and a first processing circuit 17. The first memory 15 and the first processing circuit 17 may be incorporated in another server device such as a PACS server 9.

[0019] The first communication interface 13 performs data communication, for example, between the electronic medical record server device 3, the RIS server 5, the PACS server 9, and the second communication interface 21. The standard of communication by the first communication interface 13 may be any standard, for example, HL7 (Hearth Level 7), DICOM, or both. The first communication interface 13 outputs data acquired by data communication with various server devices to the first memory 15. The first communication interface 13 outputs medical images and examination orders output from the PACS server 9 or the medical image diagnostic device 7 to the first memory 15.

[0020] The first memory 15 is a storage device such as an HDD (Hard disk Drive), an SSD (Solid State Drive), or an integrated circuit storage device that stores various information. In addition to an HDD or SSD, the first memory 15 may be a drive device that reads and writes various information between a portable storage medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a flash memory, or a semiconductor memory element such as a RAM (Random Access Memory), etc.

[0021] The first memory 15 stores various programs related to the analysis function 171 executed by the first processing circuit 17. The first memory 15 also stores data generated by execution of the analysis function 171 and the like. The generated data and these functions will be described later. The first memory 15 stores various medical information collected from various server devices and the medical image diagnostic device 7 via the first communication interface 13. For example, the first memory 15 stores an examination order and a medical image taken according to the examination order. The examination order is obtained, for example, from the electronic medical record server device 3, the RIS server 5, the medical image diagnostic device 7, or the PACS server 9 via the first communication interface 13. The medical image is obtained by the first processing circuit 17 from the medical image diagnostic device 7 or the PACS server 9 via the first communication interface 13.

[0022] The first memory 15 stores an algorithm (hereinafter, referred to as an analysis algorithm) for analyzing a medical image using the medical image. The first memory 15 stores a plurality of analysis algorithms according to, for example, the type of abnormality, the type of medical image corresponding to the type of medical image diagnostic device 7, the imaged part of the subject, etc. The analysis algorithm corresponds to, for example, an analysis application program that receives a medical image as input and outputs, as analysis results, the abnormal location in the medical image, the disease name related to the abnormality, various numerical values ​​related to the abnormality, the accuracy of the disease name, etc.

[0023] The analysis application program is, for example, a trained model such as DNN, a rule-based analysis program, etc. The analysis algorithm is not limited to these, and may be various computer algorithms related to computer-aided diagnosis (hereinafter referred to as CAD) and clinical decision support system (CDSS).

[0024] The first memory 15 stores a correspondence table indicating the presence or absence of urgency for a disease name (hereinafter referred to as a disease urgency correspondence table) or a correspondence table indicating the presence or absence of urgency for a type of analysis algorithm (hereinafter referred to as an algorithm urgency correspondence table). The first memory 15 may store a correspondence table in which a test purpose is further added to the disease urgency correspondence table or the algorithm urgency correspondence table (hereinafter referred to as a purpose-added correspondence table).

[0025] The first processing circuit 17 has, for example, as hardware resources, a processor such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or a GPU (Graphics Processing Unit), and a memory such as a ROM (Read Only Memory), a RAM, etc. The first processing circuit 17 may also be realized by an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), another Complex Programmable Logic Device (CPLD), a Simple Programmable Logic Device (SPLD), or the like.

[0026] The first processing circuit 17 has an analysis function 171. The analysis function 171 is stored in the first memory 15 in the form of a program executable by a computer. The first processing circuit 17 executes the analysis function 171 by a processor that executes the program deployed in the memory. That is, the first processing circuit 17 corresponds to a processor that realizes a function corresponding to each program by reading and executing the program from the first memory 15. In other words, the first processing circuit 17 in a state in which each program is read has the analysis function 171 corresponding to the read program. Note that the analysis function 171 is not limited to being realized by a single processing circuit. A processing circuit may be configured by combining a plurality of independent processors, and each processor may execute a program to realize the analysis function 171. The first processing circuit 17 that realizes the analysis function 171 is an example of an analysis unit.

[0027] The analysis function 171 selects at least one analysis algorithm to which a medical image is input based on the examination site, examination type, disease name, examination purpose, etc. in the examination order. The analysis function 171 detects abnormalities in the medical image by inputting the medical image to the selected analysis algorithm. The analysis function 171 outputs the analysis status of the medical image (hereinafter referred to as the analysis status) to the medical information display device 20 via the first communication interface 13. The analysis status is, for example, analyzed, analyzing, waiting for analysis, etc. Note that, regarding analyzing, the progress degree of the analysis may be indicated as a percentage. The analysis function 171 determines whether or not the disease related to the abnormality is urgent (urgency), that is, whether or not urgent medical treatment is required for the disease related to the detected abnormality, based on the information on the abnormality or the type of analysis algorithm and various correspondence tables (disease urgent correspondence table, algorithm urgent correspondence table, purpose added correspondence table) stored in the first memory 15. The analysis results by the analysis function 171 include the detected abnormality, findings and measurement results related to the abnormality, and whether or not the abnormality is urgent.

[0028] As described above, the analysis function 171 automatically performs an analysis on the medical image generated for each examination, thereby generating an analysis result for the medical image. The analysis function 171 associates the generated analysis result with the same examination ID as the medical image used in the analysis, and transmits it to the medical information display device 20, the PACS server 9, etc. via the first communication interface 13. At this time, the PACS server 9 stores the analysis result transmitted from the medical information processing device 11 in association with the medical image by the examination ID.

[0029] The medical information display device 20 has a second communication interface 21, a second memory 23, a second processing circuit 25, a display 27, and an input interface 29. The medical information display device 20 is used, for example, as a viewer for displaying medical images and a report creation device for a radiologist to create an interpretation report on the medical images.

[0030] The second communication interface 21 performs data communication between the electronic medical record server device 3, the RIS server 5, the PACS server 9, and the first communication interface 13. The standard of communication by the second communication interface 21 may be any standard, for example, HL7 (Hearth Level 7), DICOM, or both. The second communication interface 21 outputs data acquired by data communication with various server devices to the second memory 23. For example, the second communication interface 21 outputs medical images generated by the medical image diagnostic device 7 to the second memory 23. In addition, the second communication interface 21 outputs analysis results and examination orders acquired by the acquisition function 251 from the PACS server 9 or the medical information processing device 11 to the second memory 23.

[0031] The second memory 23 is a storage device such as an HDD, SSD, or integrated circuit storage device that stores various information. The second memory 23 may be a drive device that reads and writes various information between a portable storage medium such as a CD, DVD, or flash memory, or a semiconductor memory element such as a RAM, in addition to an HDD or SSD. The second memory 23 stores various programs related to the execution of the acquisition function 251, the reading list generation function 252, the priority setting function 253, the character string generation function 254, and the display control function 255 executed by the second processing circuit 25. The second memory 23 stores data acquired by the execution of the acquisition function 251. The second memory 23 also stores data generated by the execution of the reading list generation function 252, the priority setting function 253, and the character string generation function 254. The acquired data, the generated data, and these functions will be described later.

[0032] Specifically, the second memory 23 stores various medical information collected from various server devices via the second communication interface 21. For example, the second memory 23 stores the examination order, medical images, and analysis results acquired by the acquisition function 251 via the second communication interface 21 in association with the examination ID. The second memory 23 stores the interpretation list (also called a work list) generated by the interpretation list generation function 252. The interpretation list is a list of examinations for which generation of medical images has been completed. The interpretation list will be described in the interpretation list generation function 252.

[0033] The second memory 23 stores the interpretation priority set by the priority setting function 253 based on the analysis result in association with the examination ID of the analysis result. The interpretation priority indicates the priority of interpretation for a medical image. The interpretation priority will be described in the priority setting function 253. The second memory 23 stores at least one character string generated by the character string generating function 254 based on the analysis result for the medical image for which the interpretation priority has been set in association with the examination ID of the analysis result. The at least one character string is, for example, a character string indicating an abnormality in the examination result and a finding related to the interpretation priority.

[0034] The second processing circuit 25 has, for example, a processor such as a CPU, MPU, or GPU, and a memory such as a ROM or RAM, as hardware resources. The second processing circuit 25 may also be realized by an ASIC, an FPGA, a CPLD, or a SPLD. The second processing circuit 25 has an acquisition function 251, an interpretation list generating function 252, a priority setting function 253, a character string generating function 254, and a display control function 255. The acquisition function 251, the interpretation list generating function 252, the priority setting function 253, the character string generating function 254, and the display control function 255 are stored in the second memory 23 in the form of a program executable by a computer. The second processing circuit 25 executes the acquisition function 251, the interpretation list generating function 252, the priority setting function 253, the character string generating function 254, and the display control function 255 by a processor that executes various programs deployed in the memory. That is, the second processing circuit 25 corresponds to a processor that realizes a function corresponding to a program by reading the program from the second memory 23 and executing it.

[0035] In other words, the second processing circuit 25 in a state where the program is read out has a function corresponding to the read out program. The acquisition function 251, the reading list generating function 252, the priority setting function 253, the character string generating function 254, and the display control function 255 are not limited to being realized by a single processing circuit. A processing circuit may be configured by combining a plurality of independent processors, and each processor may execute a program to realize the acquisition function 251, the reading list generating function 252, the priority setting function 253, the character string generating function 254, and the display control function 255. The second processing circuit 25 that realizes the acquisition function 251, the reading list generating function 252, the priority setting function 253, the character string generating function 254, and the display control function 255 is an example of an acquisition unit, an interpretation list generating unit, a priority setting unit, a character string generating unit, and a display control unit.

[0036] The acquisition function 251 acquires the examination order, the medical image, and the analysis result via the second communication interface 21. For example, when a medical image is generated, the acquisition function 251 acquires the medical image and the examination order from the PACS server 9. Furthermore, when an analysis result is generated, the acquisition function 251 acquires the analysis result from the medical information processing device 11. Furthermore, when an analysis result is generated for a medical image, the acquisition function 251 acquires the analysis result from the medical information processing device 11. Furthermore, the acquisition function 251 acquires the analysis status from the medical information processing device 11. The acquisition function 251 associates the acquired examination order, medical image, analysis result, and analysis status with each other by an examination ID and stores them in the second memory 23.

[0037] When a medical image is acquired, the image reading list generating function 252 generates an image reading list using the analysis status, examination date and time, patient ID, patient name, etc. related to the medical image. For example, the image reading list generating function 252 updates the image reading list every time a medical image is acquired. Also, the image reading list generating function 252 updates the image reading list every time an analysis result and an analysis status are acquired. The image reading list generating function 252 stores the updated image reading list in the second memory 23. Items for each examination in the image reading list include, for example, the image reading priority, the analysis status, whether or not an emergency instruction was given by a clinician in the examination order, whether or not an emergency judgment was made in the analysis result (for example, the analysis result by CAD), the examination item, the patient ID, the patient name, etc. In the image reading list, the examinations are arranged, for example, in the order of the image reading priority.

[0038] The priority setting function 253 sets the interpretation priority based on the analysis result. The interpretation priority is a degree indicating the priority of interpretation for a medical image related to the analysis result via an examination ID. The interpretation priority may be, for example, the presence or absence of the priority of interpretation, or an index value indicating the priority of interpretation with an index. The priority setting function 253 may further use an examination order (examination order information) related to the medical image to set the interpretation priority. For example, if the examination order states that an urgent examination is to be performed according to the instruction of a clinician, the priority setting function 253 sets the interpretation priority high regardless of the presence or absence of the analysis result and the analysis situation. The priority setting function 253 assigns the examination ID attached to the analysis result related to the interpretation priority to the set interpretation priority. As a result, the interpretation priority is linked to the analysis result, the medical image, and the examination order. The priority setting function 253 also associates the interpretation priority with priority information that indicates the presence or absence of an examination for which the interpretation priority is set. The process related to the priority setting function 253 may be realized by the first processing circuit 17 in the medical information processing device 11. In this case, the priority setting function 253 is installed in the first processing circuit 17.

[0039] The character string generating function 254 generates at least one character string (hereinafter referred to as a finding character string) representing a finding related to the image interpretation priority based on the analysis result of a medical image (hereinafter referred to as an image interpretation priority image) for which an image interpretation priority has been set. For example, the finding character string is a character string representing a finding associated with a factor of high urgency from the measurement result. Specifically, when the analysis result indicates that the part of the non-specimen where an abnormality is detected is the right upper lobe of the lung, the type of the abnormality is a mass shadow, and the size of the mass shadow exceeds 32 mm, the character string generating function 254 generates a finding character string of "There is a 32 mm mass shadow in the right upper lobe of the lung." In addition to the above character string, the character string generating function 254 may generate other character strings such as "There is a 32 mm mass shadow in the right upper lobe of the lung." as the finding character string.

[0040] The character string generating function 254 may generate a finding character string (for example, "··· has increased") by comparing the analysis result with a past analysis result for a past medical image for the subject related to the interpretation priority image. At this time, prior to generating the finding character string, the acquiring function 251 acquires the past analysis result of the same patient from the electronic medical record server device 3 based on the patient ID related to the analysis result used to generate the finding character string. At this time, the processing related to the character string generating function 254 may be realized by the first processing circuit 17 in the medical information processing device 11. At this time, the character string generating function 254 is mounted on the first processing circuit 17.

[0041] The display control function 255 displays the priority information on the input screen of the image interpretation report for the medical image. The priority information is expressed by a predetermined character string such as, for example, "There is an examination with a high image interpretation priority that has been completed. Would you like to check it first?" That is, the priority information corresponds to information that prompts the user to perform preferential image interpretation for the examination for which the image interpretation priority is set. The priority information is associated with the analysis result and the medical image via the examination ID in the associated image interpretation priority. As the timing for displaying the priority information, the display control function 255 displays the priority information on the image interpretation report input screen for confirmation or saving (hereinafter referred to as a confirmation screen) in response to an operation related to input for saving the image interpretation report. The operation related to input for saving the image interpretation report corresponds to pressing a button for inputting for saving the image interpretation report (hereinafter referred to as a save button).

[0042] Specifically, in response to pressing a save button via the input interface 29, the display control function 255 superimposes the priority information on the input screen, for example, in a pop-up format on the confirmation screen. When the interpretation priority is expressed by an index value, the display control function 255 displays priority information on a high interpretation priority exceeding a predetermined threshold on the confirmation screen. The predetermined threshold is set in advance and stored in the second memory 23. When there are multiple examinations with high interpretation priority, the examinations corresponding to the priority information may be narrowed down to one examination by further using information in the examination order, such as the examination date and time. When there are multiple examinations with high interpretation priority, the priority information may be displayed as a list of examinations with high interpretation priority in order of interpretation priority or examination date and time.

[0043] The display control function 255 transitions from the display of the confirmation screen to the display of an input screen for an interpretation report for a medical image for which an interpretation priority has been set (hereinafter referred to as an interpretation priority screen) without displaying an interpretation list. For example, in response to pressing a button (hereinafter referred to as a confirmation button) for confirming the display of the interpretation priority screen, the display control function 255 switches the input screen for an interpretation report from the confirmation screen to the interpretation priority screen. At this time, the display control function 255 pastes the patient name, patient ID, examination ID, examination date and time, etc., related to the interpretation priority in the area where the examination information is displayed on the interpretation priority screen. In addition, the interpretation report for the confirmation screen is transmitted to the PACS server 9 in association with the examination ID of the medical image displayed on the confirmation screen, and is stored in the PACS server 9.

[0044] In response to the acquisition of new analysis results by the acquisition function 251, the display control function 255 displays a warning indicating that new analysis results have been acquired (hereinafter referred to as an analysis completion warning) on ​​the interpretation priority screen. The analysis completion warning is expressed by a predetermined character string such as "analysis completed examination". Specifically, in response to the display of the interpretation priority screen, the display control function 255 displays the analysis completion warning superimposed on the interpretation priority screen.

[0045] The display control function 255 displays at least one of the total number of examinations for which interpretation has not been completed (hereinafter referred to as the number of uninterpreted images), the number of examinations to which analysis results have been attached (hereinafter referred to as the number of examination results), and the number of examinations for which interpretation priority has been set (hereinafter referred to as the number of priority interpretations) on the interpretation priority screen. Hereinafter, the number of uninterpreted images, the number of examination results, and the number of priority interpretations are collectively referred to as the interpretation quantity. Specifically, in response to the display of the interpretation priority screen, the display control function 255 displays at least one of the number of uninterpreted images, the number of examination results, and the number of priority interpretations on the interpretation priority screen in a superimposed manner.

[0046] The display control function 255 displays the finding string on the image interpretation priority screen. Specifically, in response to the display of the image interpretation priority screen, the display control function 255 displays the finding string by superimposing the finding string on the image interpretation priority screen. When the finding string is one character string, the display control function 255 pastes the finding string in the finding description area in the image interpretation report creation area of ​​the image interpretation priority screen. When the finding string has multiple character strings, the display control function 255 pastes a character string selected via the input interface 29 in the finding description area.

[0047] Regarding various displays implemented by the display control function 255, the display control function 255 controls the display 27. Display examples by the display control function 255 will be described later along with the procedure for executing a process related to display control for an interpretation report (hereinafter, referred to as a report display process).

[0048] The display 27 displays various information. For example, the display 27 outputs a GUI (Graphical User Interface) for receiving various operations from an operator. As the display 27, for example, a liquid crystal display (LCD), a cathode ray tube (CRT) display, an organic electroluminescence display (OELD), a plasma display, or any other arbitrary display can be used as appropriate. The display 27 may be a desktop type, or may be configured as a tablet terminal or the like capable of wireless communication with the medical information processing device 11.

[0049] When the radiologist accesses the medical information display device 20, the display 27 displays the image reading list generated by the image reading list generating function 252. The display 27 displays an image reading report input screen for the examination selected in the image reading list. If there is an examination for which an image reading priority has been set, the display 27 displays the priority information superimposed on the confirmation screen when the confirmation button is pressed. When, for example, a "Previous" button (hereinafter referred to as the Previous button) is pressed on the confirmation screen, the image reading report on the confirmation screen is transmitted to the PACS server 9 in association with the examination ID of the medical image displayed on the confirmation screen, and is stored in the PACS server 9. In addition, the display 27 displays an image reading report input screen (hereinafter referred to as the Previous screen) for an examination (one row above) with an image reading priority one level higher than the examination corresponding to the confirmation screen in the image reading list.

[0050] Furthermore, when, for example, a "Next" button (hereinafter referred to as the "next button") is pressed on the confirmation screen, the image interpretation report on the confirmation screen is transmitted to the PACS server 9 in association with the examination ID of the medical image displayed on the confirmation screen, and is stored in the PACS server 9. In addition, the display 27 displays an input screen (hereinafter referred to as the "next screen") for an image interpretation report regarding an examination (one row below) that has an image interpretation priority level one level lower than the examination corresponding to the confirmation screen in the image interpretation list.

[0051] When, for example, a confirm button is pressed on the confirmation screen displaying the priority information, the display 27 displays an interpretation priority screen corresponding to the examination ID associated with the priority information. In conjunction with the display of the interpretation priority screen, the display 27 displays an analysis completion warning superimposed on the interpretation priority screen. In addition, in conjunction with the display of the interpretation priority screen, the display 27 displays at least one of the number of uninterpreted images, the number of examination results, and the number of priority interpretations superimposed on the interpretation priority screen. In addition, in conjunction with the display of the interpretation priority screen, the display 27 displays a finding character string superimposed on the interpretation priority screen.

[0052] The input interface 29 accepts various input operations from the operator, converts the accepted input operations into electrical signals, and outputs them to the second processing circuit 25. The input interface 29 accepts selection instructions, various conditions, and the like from the operator. For example, the input interface 29 inputs the selection of an examination in an interpretation list, various inputs on an input screen for an interpretation report, an instruction to confirm or save an interpretation report, and the selection of a finding character string. The input interface 29 also inputs the pressing of a confirm button, a previous button, or a next button. As the input interface 29, for example, a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad, a touch panel display, and the like can be used as appropriate.

[0053] In this embodiment, the input interface 29 is not limited to one having physical operation parts such as a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad, and a touch panel display. For example, an example of the input interface 29 includes an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the device and outputs the electrical signal to the second processing circuit 25. The input interface 29 may be configured with a tablet terminal or the like capable of wireless communication with the medical information display device 20.

[0054] The above describes the overall configuration of the medical information display system 1. The following describes the procedure of the report display process. Figures 2 and 3 are flowcharts showing an example of the procedure of the report display process.

[0055] (Report display process) (Step S201) The display control function 255 displays the interpretation list on the display 27 when the radiologist accesses the medical information display device 20. That is, the display control function 255 displays the interpretation list on the display 27 prior to the first interpretation by the radiologist.

[0056] FIG. 4 is a diagram showing an example of an interpretation list. As shown in FIG. 4, in the interpretation list IL, examinations are arranged, for example, in the order of the highest interpretation priority. The examination at the top of the interpretation list IL is marked with an "urgent" flag in response to an instruction from a clinician for patient A. In addition, when there is no urgency in the item of the judgment result by the analysis function 171 (hereinafter referred to as CAD result), the emergency information EI is hidden. In the interpretation list IL in FIG. 4, two columns related to urgency are shown, one by a clinician and one by a CAD result, but this is not limiting. Also, as shown in FIG. 4, the column related to the analysis status displays the analysis status in the analysis function 171, interpretation information indicating whether or not an interpretation has been performed, and the modality name related to the examination.

[0057] As shown in Figure 4, the examination in the second row of the image interpretation list IL does not have an "urgent" flag because there is no urgent instruction from the clinician for patient B. On the other hand, in the examination order SOI in the second row, the analysis results of the medical images by the analysis algorithm have been determined to be urgent, so the word "urgent" is displayed as emergency information EI in the CAD results section.

[0058] As shown in Figure 4, the examination in the sixth row in the image reading list IL does not have an "urgent" flag because there is no urgent instruction from the clinician for patient F. The examination in the sixth row has been interpreted, but the analysis algorithm has not been completed, so it remains in the image reading list.

[0059] (Step S202) The input interface 29 allows a radiologist to input an operation for selecting one examination in the image interpretation list IL displayed on the display 27. The display control function 255 displays on the display 27 an input screen for an image interpretation report corresponding to the selected examination.

[0060] (Step S203) The input interface 29 is operated by a radiologist to input findings and impressions into an image interpretation report creation area on an image interpretation report input screen.

[0061] (Step S204) When the image interpretation report is finalized (Yes in step S204), the process of step S205 is executed. Finalizing the image interpretation report corresponds to pressing the save button. If the image interpretation report is not finalized (No in step S204), the process of step S203 is repeated.

[0062] (Step S205) If there is an examination for which an interpretation priority has been set (Yes in step S205), the process of step S212 is executed. If there is no examination for which an interpretation priority has been set (No in step S205), the process of step S206 is executed. If the result in this step is No, the display control function 255 displays a previous button and a next button on the display 27, superimposed on the confirmation screen.

[0063] (Step S206) When an operation to end the interpretation is input via the input interface 29 (Yes in step S206), the creation of the interpretation report ends and this report display process ends. If an operation to end the interpretation is not input via the input interface 29 (No in step S206), the process of step S207 is executed. Specifically, when the previous button or the next button is pressed on the confirmation screen, the process of step S207 is executed. The operation to end the interpretation can be performed between any steps.

[0064] (Step S207) The display control function 255 displays an input screen for an image interpretation report related to an examination other than the examination related to the confirmation screen on the display 27. Specifically, when the previous button is pressed, the display control function 255 displays the previous screen on the display 27. When the next button is pressed, the display control function 255 displays the next screen on the display 27. After this step, the process of step S203 is executed.

[0065] (Step S208) When an examination is performed during the processing of steps S201 to S207, a medical image is generated by the medical image diagnostic apparatus 7. The medical image diagnostic apparatus 7 attaches an examination ID to the generated medical image, and transmits the medical image with the examination ID attached to the PACS server 9. The PACS server 9 stores the generated medical image, and transmits the medical image to the medical information processing device 11 and the medical information display device 20. The medical image diagnostic apparatus 7 may transmit the medical image with the examination ID attached to the PACS server 9 and the medical information processing device 11.

[0066] (Step S209) The analysis function 171 generates an analysis result by performing an analysis on the medical image using an analysis algorithm. The medical information processing device 11 attaches an examination ID to the analysis result, and transmits the analysis result with the examination ID to the PACS server 9 and the medical information display device 20. The PACS server 9 stores the analysis result. The medical information processing device 11 transmits the analysis result to the PACS server 9, and the PACS server 9 may store the analysis result and transmit the analysis result to the medical information display device 20. The medical information display device 20 stores the received analysis result in the second memory 23.

[0067] (Step S210) The priority setting function 253 sets the reading priority based on the analysis result. The analysis result is acquired from the medical information processing device 11 by the acquisition function 251. For example, when the analysis result does not include an abnormality having urgency, the priority setting function 253 sets the reading priority of the medical image related to the analysis result to none or the lowest index value. Also, when the analysis result includes an abnormality having urgency, the priority setting function 253 sets the reading priority of the medical image related to the analysis result to yes or the highest index value. When the analysis result includes an abnormality not having urgency, the priority setting function 253 sets the reading priority of the medical image related to the analysis result to none or an index value according to the malignancy or progression of the abnormality. The priority setting function 253 attaches an examination ID to the set reading priority and stores the reading priority in the second memory 23. The priority setting function 253 may further use an examination order to set the reading priority. At this time, the examination order is acquired by the acquisition function 251 from any one of the electronic medical record server device 3, the RIS server 5, the PACS server 9, and the medical information processing device 11.

[0068] (Step S211) The character string generating function 254 generates a finding character string based on the analysis result. The character string generating function 254 attaches an examination ID to the generated finding character string and associates it with the analysis result. The character string generating function 254 stores the generated finding character string in the second memory 23.

[0069] (Step S212) The display control function 255 displays the priority information superimposed on the input screen of the interpretation report regarding the interpretation priority. FIG. 5 is a diagram showing an example of a confirmation screen CS on which the priority information is superimposed. As shown in FIG. 5, the display control function 255 superimposes the priority information PI on the confirmation screen CS. Also, as shown in FIG. 5, in addition to the priority information PI, a confirmation button CB, a previous button BB, and a next button are displayed on the confirmation screen CS. With this step, when the analysis of the medical image is completed and there is an examination with a high interpretation priority, it is possible to prompt the user to interpret the examination on the input screen of the interpretation report.

[0070] (Step S213) When an examination related to priority information is selected on the confirmation screen CS via the input interface 29 (Yes in step S213), the process of step S214 is executed. Specifically, when the confirmation button CB is pressed on the confirmation screen CS, the process of step S214 is executed. If an examination related to priority information is not selected on the confirmation screen CS via the input interface 29 (No in step S213), the process of step S207 is executed. Specifically, when the previous button BB or the next button NB is pressed on the confirmation screen CS, the process of step S207 is executed.

[0071] (Step S214) The display control function 255 superimposes an analysis completion warning, a finding character string, and an interpretation quantity on the image interpretation priority screen on the display 27. The display control function 255 may superimpose at least one of the analysis status, the finding character string, and the image interpretation quantity on the image interpretation priority screen on the display 27. The display control function 255 may further superimpose the analysis status on the image interpretation priority screen on the display 27.

[0072] Fig. 6 is a diagram showing an example of an interpretation priority screen IPS on which an analysis completion warning ADA, a finding string IS, and an interpretation quantity IQN are superimposed. As shown in Fig. 5, an analysis completion warning ADA, a finding string IS, and an interpretation quantity IQN are superimposed on the interpretation priority screen IPS by the display control function 255. Note that the finding string IS may have multiple strings.

[0073] (Step S215) When a character string of a finding is selected via the input interface 29, the display control function 255 pastes the selected character string of the finding in the description area of ​​the finding on the image interpretation priority screen IPS. When there is only one character string of the finding, the display control function 255 pastes one character string of the finding in the description area of ​​the finding on the image interpretation priority screen IPS. Also, for example, when the analysis completion warning ADA, the finding character string IS, and the image interpretation quantity IQN are clicked, the analysis completion warning ADA, the finding character string IS, and the image interpretation quantity IQN are hidden on the image interpretation priority screen IPS. The analysis completion warning ADA, the finding character string IS, and the image interpretation quantity IQN may be hidden by pressing a hide button displayed on the image interpretation priority screen IPS.

[0074] As shown in FIG. 2 and FIG. 3, during image interpretation, the image interpretation list is displayed in the first image interpretation, and is not displayed on the display 27 in the second and subsequent image interpretations. That is, in the second and subsequent image interpretations, the image interpretation list is not returned from the image interpretation report input screen. This makes it possible to improve the efficiency of image interpretation report creation and the operability of image interpretation report creation. In addition, even if there is an examination for which an image interpretation priority has been set after the image interpretation by the radiologist, the radiologist can be prompted to perform the image interpretation, thereby preventing image interpretation omissions. In addition, in this report display process, each time an image interpretation priority is set, the user can be prompted to perform the image interpretation of the examination for which the image interpretation priority has been set as a priority, so that the image interpretation can be performed in order of the image interpretation priority, and the image interpretation can be performed publicly.

[0075] According to the medical information display device 20 of the embodiment described above, the analysis result for the medical image generated for each examination is acquired, the image reading priority is set based on the analysis result, and the priority information is displayed on the confirmation screen. According to the medical information display device 20, an image reading list for the examination for which the generation of the medical image is completed is generated, and the display of the confirmation screen CS is transitioned to the image reading priority screen IPS without displaying the image reading list. According to the medical information display device 20, in response to the acquisition of a new analysis result by the acquisition function 251, at least one of the number of uninterpreted images, the number of examination results, and the number of priority image readings, the analysis completion warning ADA, and the finding string IS are displayed on the image reading priority screen IPS. According to the medical information display system 1 of the embodiment, the analysis result for the medical image is generated by performing an analysis on the medical image generated for each examination, the analysis result is acquired from the medical information processing device 11, the image reading priority is set based on the analysis result, and the priority information is displayed on the confirmation screen.

[0076] From these facts, the medical information display device 20 according to the embodiment can present the user with the image analysis result (urgency) and the interpretation priority considering the analysis situation when the user determines the next examination to be interpreted in the report application for creating an interpretation report. That is, the medical information display device 20 cooperates with the medical information processing device 11 that analyzes the medical image, and can present the user with various information based on the interpretation priority considering the analysis situation and the analysis result (urgency) of the medical image, without returning to the interpretation list from the input screen of the interpretation report.

[0077] Moreover, according to the medical information display device 20 of the embodiment, the examination order for the medical image is further used to set the interpretation priority. As a result, according to the medical information display device 20, the interpretation priority can be set based on the judgment of the clinician, and the reliability of the interpretation priority can be improved.

[0078] According to the present medical information display device 20, a finding string may be generated based on the analysis result of the medical image for which the interpretation priority is set, and the finding string may be displayed on the interpretation priority screen. In this case, according to the medical information display device 20, when there are multiple finding strings, a finding string selected by the user, or when there is only one finding string, one finding string may be pasted and displayed in an area for describing findings on the interpretation priority screen. Furthermore, according to the medical information display device 20 according to the embodiment, a finding string is generated by comparing the analysis result with an analysis result of a past medical image of a subject related to the medical image corresponding to the analysis result. As a result, according to the present medical information display device 20, the efficiency of inputting findings by a user can be improved.

[0079] According to the medical information display device 20 of the embodiment, the interpretation priority is expressed as an index value, and priority information regarding a high interpretation priority exceeding a predetermined threshold is displayed on the confirmation screen. This makes it possible to prompt the user to interpret an examination with a higher interpretation priority even if there are multiple examinations with interpretation priorities set.

[0080] From the above, the medical information display device 20 according to the embodiment can improve the efficiency of image interpretation by presenting image interpretation priority that takes into account the analysis status / urgency of medical images. In addition, the medical information display device 20 can reduce omissions in image interpretation by utilizing the analysis results.

[0081] When the technical idea of ​​this embodiment is realized in a medical information processing method, the medical information processing method acquires the analysis results for the medical images generated for each examination, sets the interpretation priority based on the analysis results, and displays the priority information on a confirmation screen. The processing procedure and effects of the medical information processing method are the same as those of the embodiment, and therefore will not be described.

[0082] When the technical idea of ​​this embodiment is realized by a medical information processing program, the medical information processing program causes a computer to obtain analysis results for medical images generated for each examination, set image interpretation priorities based on the analysis results, and display priority information on a confirmation screen. At this time, a program capable of causing a computer to execute the method can be stored in a storage medium such as a magnetic disk (hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), or a semiconductor memory and distributed. The processing procedure and effects of the medical information processing program are the same as those of the embodiment, and therefore will not be described.

[0083] According to at least one of the embodiments described above, information for giving priority to image interpretation based on the analysis result of the medical image can be displayed on the input screen for the image interpretation report.

[0084] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
