Description

Technical Field

[0001] The present invention relates to a medical information management device and a medical information management program.

Background Art

[0002] Generally, a diagnostic method is used in which an image obtained by radiographing a patient in the past is compared with the current image to detect an abnormality such as a lesion. However, since there is not always an image of a normal case in the past (hereinafter referred to as a normal image) for the patient to be diagnosed, an image similar to the normal structure of the patient to be diagnosed is extracted from a large-scale image database consisting of normal images, and the difference between the extracted normal image and the image of the patient to be diagnosed (hereinafter referred to as the diagnostic target image) is used. A technique using a similar difference image as a diagnostic aid image has been proposed (see Patent Document 1). However, since there are individual differences in the shape of organs and artifacts occur in the similar difference image, when the shape of the organ matches between the normal image and the diagnostic target image in the image database, a similar difference image is generated.

[0003] By the way, the above-mentioned conventional technique relates to a still image of radiography, and it is known that an image in the maximum exhalation position is used as an example of a normal image in a still image. On the other hand, in recent years, diagnosis using dynamic images (dynamic information) obtained from dynamic radiography has been attempted. However, since it is not fully understood what is a normal image in dynamic images, for dynamic images as well, judgments are made based on the knowledge of normal images in still images.

[0004] However, there is a problem that the shapes of structures such as organs and bones in an image in the maximum exhalation position may not show a large difference between a normal image and an image of a patient having a disease, and a doctor cannot fully diagnose using a dynamic image only based on the knowledge of a normal image in a still image.

[0005] In addition, since the amount of information in a dynamic image is much larger than that in a still image, the importance of a normal image as a diagnostic criterion is increasing.

[0006] Furthermore, because dynamic images are videos, they take more time to view than still images. Viewing every frame of a video would drastically increase the workload for physicians, making it unacceptable. Therefore, in dynamic images, it is even more important than with still images to improve the efficiency of physicians' viewing and diagnosis. This requires diagnostic support such as analyzing video data and marking or highlighting potential abnormal areas. Since normal images are necessary for extracting potential abnormal areas for such diagnostic support, collecting normal images becomes even more important in videos compared to still images.

[0007] [Patent Document 1] Japanese Patent Publication No. 2016-174735 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, because dynamic imaging is a new technology, there are problems such as a small amount of data on normal and abnormal cases, and a small number of physicians with knowledge of dynamic imaging and analysis. Furthermore, regarding dynamic imaging information, there is a demand to view it in comparison with information obtained using conventional diagnostic methods other than dynamic imaging (medical images taken with other modalities, test results, etc.).

[0009] Furthermore, in order to widely disseminate dynamic imaging, it is necessary to make normal and abnormal examples publicly available for viewing and download, thereby educating users and stimulating further research. Establishing quantitative diagnostic criteria (standard values) for dynamic images is also necessary to promote the use of dynamic imaging. Thus, in order to advance the utilization of dynamic imaging, it is necessary to deepen our understanding of dynamic imaging and to accumulate dynamic images in an easily usable format.

[Effects of the Invention]

[0039] According to the present invention, the utilization of dynamic information can be promoted. [Brief explanation of the drawing]

[0040] [Figure 1]This figure shows the system configuration of a medical information management system in an embodiment of the present invention. [Figure 2] This is a block diagram showing the functional configuration of a medical information management device. [Figure 3] This figure shows an example of the data structure of a user management table. [Figure 4] This figure shows an example of the data structure of a medical information management table. [Figure 5] This block diagram shows the functional configuration of the client terminal. [Figure 6] This is a ladder chart illustrating the medical information provision process executed by client terminals and medical information management devices. [Figure 7] This flowchart shows the medical information extraction process performed by the medical information management device. [Modes for carrying out the invention]

[0041] Embodiments of the medical information management device and medical information management program according to the present invention will be described below with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[0042] [Configuration of the medical information management system] Figure 1 shows the system configuration of the medical information management system 100 in an embodiment of the present invention. As shown in Figure 1, the medical information management system 100 is comprised of a medical information management device 10 and client terminals 20 used by medical professionals belonging to each medical facility. The medical information management device 10 and the client terminals 20 are connected via a communication network N to enable data communication.

[0043] The medical information management device 10 stores and manages medical information uploaded from client terminals 20. The medical information management device 10 provides the medical information to the requesting client terminal 20 in response to a viewing request from the client terminal 20. The medical information management device 10 may also be a cloud server. Medical information includes both dynamic and static information.

[0044] Dynamic information is information obtained by performing dynamic imaging on a subject, and includes at least one of dynamic images (medical images obtained by dynamic imaging) and motion information. Dynamic imaging is a type of imaging that captures the dynamics of the lungs, such as their expansion and contraction during respiratory movement, and the heartbeat. In dynamic imaging, multiple images showing the dynamics of the subject are obtained by repeatedly irradiating the subject with pulsed radiation, such as X-rays, at predetermined time intervals (pulsed irradiation), or by continuously irradiating it with a low dose without interruption (continuous irradiation). Dynamic imaging includes video recording, but does not include fluoroscopy, which captures still images while displaying video.

[0045] A motion image is a series of images (image data) obtained through motion photography. Each of the multiple images that make up a motion image is called a frame image. Motion images include videos, but do not include images obtained by taking still images while a video is playing.

[0046] Motion information is information representing the movement of a subject (such as tissues related to the respiratory, circulatory, orthopedic, and swallowing systems) obtained by analyzing dynamic images (medical images obtained through dynamic imaging). Motion information includes information such as the position obtained for each frame image, the velocity obtained from the difference between frame images, and the maximum velocity and rate of change in size obtained analytically from this information. As motion information, quantitative information of tissue movement such as diaphragmatic velocity, lung field area change rate, and airway diameter stenosis rate is used.

[0047] Non-kinetic information refers to information obtained by performing imaging or examinations other than dynamic imaging on the subject, and includes information obtained from CT, scintigraphy, MRI, spirometry, reports (interpretation reports, examination reports, etc.), etc.

[0048] Non-dynamic information includes medical images obtained by imaging other than dynamic imaging (non-dynamic images). Medical images in non-dynamic information include at least one of a first medical image (radioactive image) obtained from at least one of still imaging using radiation and fluoroscopy, and a second medical image (non-radioactive image) obtained by imaging other than radiation. Still image imaging methods include simple X-ray imaging, CT scans, and scintigraphy. Fluoroscopy is a technique that uses radiation to visualize the inside of the body, including organs and bones, and captures still images while displaying a video feed. Other imaging techniques besides radiation include MRI, etc.

[0049] Non-dynamic information includes at least one of the following: test results (measured values, etc.) obtained from tests that do not involve imaging, and test reports (reports concerning the tests). Non-imaging tests include spirometry and pulse oximetry (SpO2: transcutaneous arterial oxygen saturation).

[0050] The client terminal 20 is a computer device such as a PC (Personal Computer) or tablet used within each medical facility. The client terminal 20 uploads medical images (dynamic and static images) obtained by photographing patients at the medical facility, as well as medical information such as test results obtained from examinations of patients, to the medical information management device 10, and displays medical information stored in the medical information management device 10.

[0051] Figure 2 shows the functional configuration of the medical information management device 10. As shown in Figure 2, the medical information management device 10 is composed of a control unit 11, an operation unit 12, a display unit 13, a communication unit 14, a storage unit 15, etc., and each unit is connected by a bus.

[0052] The control unit 11 consists of a CPU (Central Processing Unit), RAM (Random Access Memory), etc., and comprehensively controls the processing operations of each part of the medical information management device 10. The CPU of the control unit 11 reads the system program and various processing programs stored in the memory unit 15, loads them into the RAM, and executes various processes according to the loaded programs.

[0053] The operation unit 12 is comprised of a keyboard equipped with cursor keys, character and number input keys, and various function keys, and a pointing device such as a mouse. It outputs instruction signals input by key operations on the keyboard or mouse operations to the control unit 11.

[0054] The display unit 13 is composed of a monitor such as an LCD (Liquid Crystal Display) and displays various screens according to the instructions of the display signals input from the control unit 11.

[0055] The communication unit 14 is composed of a network interface and the like, and performs data transmission and reception with external devices connected via a communication network N such as the Internet.

[0056] The storage unit 15 is composed of an HDD (Hard Disk Drive), SSD (Solid State Drive), etc., and stores various processing programs, parameters and files necessary for the execution of those programs. For example, the storage unit 15 stores a web server program that enables the function of a web server to communicate with a web browser installed on the client terminal 20 using the HTTP protocol and provide various web screens to the web browser, as well as application programs that run on the web server.

[0057] The memory unit 15 stores a medical information management program 151, a user management table 152, and a medical information management table 153. The memory unit 15 also has a data storage area 154.

[0058] The user management table 152 is a table used to manage the access scope of each user (healthcare professional) who uses the medical information management system 100.

[0059] Figure 3 shows an example of the data structure of user management table 152. The user management table 152 associates each user with their user ID, password, access rights to dynamic images, access rights to motion information, access rights to medical images (non-dynamic images) in non-dynamic information, and access rights to examination results. Note that when the term "medical image" is used in reference to medical images included in non-dynamic information, it refers to non-dynamic images only and does not include dynamic images. A user ID is a user's identification information. Passwords are used for user authentication when users log in to the system. In each item of the user management table 152 (dynamic images, motion information, medical images, test results, etc.), "○" indicates that access is permitted, and "×" indicates that access is not permitted.

[0060] Medical information management table 153 is a table for managing medical information and is pre-configured. The medical information managed in medical information management table 153 is collected from each medical facility.

[0061] Figure 4 shows an example of the data structure of medical information management table 153. Medical information management table 153 associates dynamic and static information for each combination of disease information, attribute information, imaging site, and hospital information.

[0062] Disease information refers to information about diseases present in the subject. Examples of disease information include COPD (chronic obstructive pulmonary disease), interstitial pneumonia, and no disease. Attribute information refers to information that indicates the attributes of the subject. Examples of attribute information include gender, date of birth, age, height, BMI, race, and smoking history. Attribute information does not include information that identifies an individual. Examples of information that identifies an individual include name, address, and telephone number. The imaging site is information indicating the body part that was photographed. Examples of imaging sites include the lungs, heart, vocal cords, elbows, and knees. Hospital information refers to the hospital (medical facility) where imaging or examination was performed on the subject. This information may include the medical department (e.g., internal medicine, orthopedics) and the physicians involved in the imaging or examination.

[0063] Dynamic information includes dynamic images and motion information (diaphragmatic velocity, lung field area change rate, airway diameter stenosis rate, etc.). The "Dynamic Image" field stores identification information to identify the dynamic image. In the medical information management table 153, the "Dynamic Image" included in each record may be a single dynamic image or a group of multiple dynamic images (a group of images with similar motion information). The motion information may be information obtained by the medical information management device 10 analyzing dynamic images, or it may be information acquired from an external device.

[0064] Non-dynamic information includes information obtained for each imaging or examination other than dynamic imaging. Non-dynamic information related to imaging such as CT, MRI, and scintigraphy includes medical images, findings, and measurements. The "Medical Images" field stores identification information to identify medical images obtained through methods other than motion imaging (non-motion images). The "Findings" field stores representative findings for non-dynamic images. The "Measured Value" field stores representative measured values ​​calculated from the non-dynamic image. Non-dynamic information related to non-imaging tests such as spirometry includes test results (measured values), etc.

[0065] The data storage area 154 stores medical information (dynamic and non-dynamic information) uploaded from the client terminals 20 of each medical facility.

[0066] Furthermore, the memory unit 15 stores standard values ​​for each motion information item (diaphragmatic velocity, lung area change rate, airway diameter stenosis rate, etc.). Standard values ​​are values ​​set based on motion information obtained by analyzing dynamic images of patients without disease, and are values / ranges used as diagnostic criteria. For example, standard values ​​are used when determining whether the motion information values ​​are normal or abnormal.

[0067] When the control unit 11 receives an access request to the medical information management device 10 from a client terminal 20 using a login account (user ID and password) corresponding to a user, it refers to the user management table 152 in the storage unit 15 to determine whether the user is one that has been registered in advance. If the user ID and password entered on the client terminal 20 are registered in the user management table 152, the control unit 11 determines that the user corresponding to this user ID is a legitimate user.

[0068] The control unit 11 provides the requested medical information to the client terminal 20 in response to a viewing request from the client terminal 20.

[0069] The control unit 11 manages dynamic information obtained by performing dynamic radiography on a first subject that meets the conditions for a predetermined disease, and non-dynamic information obtained by performing imaging or examinations other than dynamic radiography on a second subject that meets the conditions for a predetermined disease, in association with each other. In other words, the control unit 11 functions as a management means.

[0070] For example, "not having the specified disease" can be used as the "condition for the specified disease." In this case, the first subject who meets the condition for the specified disease does not have the specified disease, and the second subject who meets the condition for the specified disease does not have the specified disease.

[0071] Furthermore, "having a specified disease" can be used as a "condition for a specified disease." In this case, the first subject who meets the conditions for a specified disease has the specified disease, and the second subject who meets the conditions for a specified disease has the specified disease.

[0072] The first subject and the second subject may be different subjects or the same subject. However, if the "condition for a specified disease" is "no disease," it is unlikely that various imaging and examinations would be performed on a patient without a disease, so basically, the first subject and the second subject are different subjects.

[0073] The control unit 11 manages dynamic and static information in association with each other based on at least one of the disease information, attribute information, imaging site information, and hospital information of the first subject and the second subject. In addition, while the medical information management table 153 manages dynamic and static information by associating them based on combinations of disease information, attribute information, imaging site, and hospital information, it is not necessary for the medical information management table 153 to include some of the conditions of the disease information, attribute information, imaging site, or hospital information that associate the dynamic and static information.

[0074] The control unit 11 manages dynamic information obtained by performing dynamic radiography on a first subject who does not have the specified disease, and non-dynamic information obtained by performing imaging or examinations other than dynamic radiography on a second subject who does not have the specified disease, in association with each other. It also manages dynamic information obtained by performing dynamic radiography on a third subject who has the specified disease, and non-dynamic information obtained by performing imaging or examinations other than dynamic radiography on a fourth subject who has the specified disease, in association with each other.

[0075] The communication unit 14 receives requests from external devices. In other words, the communication unit 14 functions as a receiving means. Based on a request, the control unit 11 outputs dynamic information obtained by performing dynamic radiography on a first subject that meets the conditions for a predetermined disease to an external device. In other words, the control unit 11 functions as an output means. "Outputting dynamic information to an external device" includes displaying the dynamic information on the external device and transmitting the dynamic information to the external device as data.

[0076] Furthermore, based on a request, the control unit 11 outputs non-dynamic information obtained by performing imaging or examinations other than dynamic imaging on a second subject that meets the conditions for a predetermined disease to an external device. "Outputting non-dynamic information to an external device" includes displaying the non-dynamic information on the external device, transmitting the non-dynamic information to the external device as data, etc.

[0077] Figure 5 shows the functional configuration of the client terminal 20. As shown in Figure 5, the client terminal 20 is composed of a control unit 21, an operation unit 22, a display unit 23, a communication unit 24, a storage unit 25, etc., and each unit is connected by a bus.

[0078] The control unit 21 consists of a CPU, RAM, etc., and comprehensively controls the processing operations of each part of the client terminal 20. The CPU of the control unit 21 reads system programs and various processing programs stored in the memory unit 25, loads them into RAM, and executes various processes according to the loaded programs.

[0079] The operation unit 22 is configured with a keyboard equipped with cursor keys, character / number input keys, and various function keys, and a pointing device such as a mouse, and outputs instruction signals input by key operations on the keyboard or mouse operations to the control unit 21. The operation unit 22 may also be equipped with a touch panel on the display screen of the display unit 23, in which case it outputs instruction signals input via the touch panel to the control unit 21.

[0080] The display unit 23 is comprised of a monitor such as an LCD and displays various screens according to the instructions of the display signals input from the control unit 21. For example, the display unit 23 displays various web screens based on the display data for various web screens received from the medical information management device 10.

[0081] The communication unit 24 is composed of a network interface and the like, and performs data transmission and reception with external devices connected via a communication network N such as the Internet.

[0082] The storage unit 25 is composed of an HDD, SSD, etc., and stores various processing programs, parameters and files necessary for the execution of those programs. For example, the storage unit 25 stores a web browser program for implementing a web browser.

[0083] [Operation of the medical information management system] Next, we will explain the operation of the medical information management system 100. Figure 6 is a ladder chart showing the medical information provision process performed by the client terminal 20 and the medical information management device 10. The processing in the medical information management device 10 is realized by software processing through the cooperation of the CPU of the control unit 11 and the medical information management program 151 stored in the memory unit 15. The processing in the client terminal 20 is realized by software processing through the cooperation of the CPU of the control unit 21 and the program stored in the memory unit 25. This processing is performed, for example, when a medical professional (user) at a medical facility views medical information for a subject with the same or similar conditions as the image to be diagnosed, in order to use it as a reference for diagnosing newly captured dynamic images.

[0084] First, when a user operates the control unit 22 on the client terminal 20 and enters a URL to access the medical information management device 10 from a web browser, the control unit 21 accesses the medical information management device 10 via the communication unit 24 based on the entered URL.

[0085] In the medical information management device 10, the control unit 11 transmits display data to the client terminal 20 via the communication unit 14 to display the login screen. The display data for various web screens, including the login screen, transmitted to the client terminal 20 by the web server function of the medical information management device 10 includes HTML, stylesheets, image data, scripts for executing predetermined processes on the client terminal 20, etc.

[0086] On the client terminal 20, the login screen is displayed on the display unit 23. The login screen includes input fields for the user ID and password. When the user operates the operation unit 22 on the login screen and enters the user ID and password (step S1), the control unit 21 transmits the entered user ID and password to the medical information management device 10 via the communication unit 24.

[0087] In the medical information management device 10, when the communication unit 14 receives the user ID and password, the control unit 11 performs user authentication (step S2). Specifically, the control unit 11 searches the user management table 152 of the storage unit 15 for a record that matches the received user ID, and determines that user authentication was successful if the password contained in the searched record matches the received password.

[0088] Next, the control unit 11 obtains the user's access scope from the user management table 152 (step S3). Specifically, the control unit 11 refers to the user management table 152 to obtain access rights to the logged-in user's dynamic images, motion information, non-dynamic information, medical images (non-dynamic images), test results, etc.

[0089] Next, the control unit 11 transmits display data to the client terminal 20 via the communication unit 14 for displaying the search condition specification screen. On the client terminal 20, the display unit 23 shows a search criteria specification screen. The search criteria specification screen includes a specification area for specifying disease information, attribute information, imaging site, and hospital information. When the user operates the operation unit 22 on the search criteria specification screen to specify disease information, attribute information, imaging site, and hospital information, the control unit 21 sends a request for medical information that satisfies the specified search criteria to the medical information management device 10 via the communication unit 24 (step S4).

[0090] For example, search criteria such as "No disease" for "Disease information," "Male, in his 30s" for "Attribute information," "Chest" for "Image site," and "Not specified" for "Hospital information" can be specified.

[0091] Additionally, search criteria such as "COPD" for "disease information," "smoking history" for "attribute information," "chest" for "imaging site," and "internal medicine" for "hospital information" can be specified.

[0092] In the medical information management device 10, when the communication unit 14 receives a request including search conditions, the control unit 11 extracts medical information that matches the search conditions from the medical information management table 153 in the storage unit 15, within the scope of access permitted to the user (step S5).

[0093] Next, the control unit 11 transmits display data for displaying the extracted medical information to the client terminal 20 via the communication unit 14 (step S6).

[0094] On the client terminal 20, medical information is displayed on the display unit 23 (step S7). The user views the medical information displayed on the display unit 23. Furthermore, on the client terminal 20, the user may operate the operation unit 22 to select the medical information to be downloaded from the medical information displayed on the display unit 23, thereby downloading the selected medical information from the medical information management device 10 (storing it on the client terminal 20 or another device within the medical facility). This concludes the medical information provision process.

[0095] Figure 7 is a flowchart showing the medical information extraction process performed by the medical information management device 10. The medical information extraction process provides a detailed explanation of step S5 of the medical information provision process (see Figure 6).

[0096] The control unit 11 of the medical information management device 10 determines whether the user's access scope obtained in step S3 of the medical information provision process covers all medical information (step S11).

[0097] If the user's access scope is to all medical information (Step S11; YES), the control unit 11 extracts all dynamic and non-dynamic information from the medical information management table 153 of the storage unit 15 that matches the search criteria (combination of disease information, attribute information, imaging site, and hospital information) (Step S12). Specifically, the control unit 11 extracts all dynamic information (dynamic images, motion information) and non-dynamic information (medical images for each modality, findings, measured values, and test results for each test) contained in the records corresponding to the combination of disease information, attribute information, imaging site, and hospital information specified by the user in the medical information management table 153. Dynamic images are obtained from the data storage area 154 of the storage unit 15 based on the identification information of the dynamic images, and medical images (non-dynamic images) in the non-dynamic information are obtained from the data storage area 154 based on the identification information of the medical images.

[0098] In step S11, if the user's access range does not include all medical information (step S11; NO), the control unit 11 determines whether or not dynamic images are included in the user's access range (step S13).

[0099] If the user's access range includes motion images (step S13; YES), the control unit 11 extracts motion images that match the search criteria from the medical information management table 153 (step S14). Specifically, the control unit 11 acquires motion images from the data storage area 154 based on the identification information of the motion images extracted from the medical information management table 153.

[0100] In step S13, if the user's access range does not include motion images (step S13; NO), or after step S14, the control unit 11 determines whether or not motion information is included in the user's access range (step S15).

[0101] If the user's access range includes motion information (step S15; YES), the control unit 11 extracts motion information that matches the search criteria from the medical information management table 153 (step S16).

[0102] In step S15, if motion information is not included in the user's access range (step S15; NO), or after step S16, the control unit 11 determines whether or not medical images (non-motion images) in the non-motion information are included in the user's access range (step S17).

[0103] If the user's access range includes medical images (non-dynamic images) in the non-dynamic information (step S17; YES), the control unit 11 extracts medical images (non-dynamic images), findings, and measurements from the medical information management table 153 that match the search criteria (step S18). Medical images (non-dynamic images) in the non-dynamic information are obtained from the data storage area 154 based on the identification information of the medical images.

[0104] In step S17, if the user's access range does not include medical images (non-dynamic images) in the non-dynamic information (step S17; NO), or after step S18, the control unit 11 determines whether or not the user's access range includes the examination results (step S19).

[0105] If the user's access scope includes the test results (step S19; YES), the control unit 11 extracts the test results that match the search criteria from the medical information management table 153 (step S20).

[0106] In step S19, if the user's access scope does not include the test results (step S19; NO), the medical information extraction process ends after step S20 or after step S12.

[0107] If the user operating the client terminal 20 has access rights to the dynamic and non-dynamic information, the control unit 11 of the medical information management device 10 transmits display data for displaying the dynamic and non-dynamic information that matches the search criteria to the client terminal 20 via the communication unit 14. On the client terminal 20, dynamic and non-dynamic information matching the search criteria is displayed on the display unit 23. Users can view dynamic images and motion information while comparing them with medical images (non-dynamic images) and examination results related to imaging other than dynamic imaging.

[0108] Furthermore, if the user operating the client terminal 20 has access rights to the motion information, the control unit 11 of the medical information management device 10 may obtain standard values ​​for each item of motion information from the storage unit 15 and display these standard values, along with motion information that matches the search criteria, on the display unit 23 of the client terminal 20. The user can then view the motion information while referring to the standard values ​​for each item.

[0109] Furthermore, the medical information management device 10 may have an AI (Artificial Intelligence) algorithm for receiving dynamic information to be diagnosed, determining whether it is normal or abnormal, and identifying the name of the disease. The dataset stored in the medical information management table 153 can be used as training data for this AI algorithm. Specifically, dynamic information obtained by performing dynamic radiography on a first subject who meets the conditions for a predetermined disease, and non-dynamic information obtained by performing imaging or examinations other than dynamic radiography on a second subject who meets the conditions for a predetermined disease, are used as input data, and the conditions for the predetermined disease (disease name, no disease, etc.) are used as output data to perform machine learning. When the dynamic and non-dynamic information of the patient (subject) to be diagnosed is input to the classifier generated by this machine learning, the presence or absence of disease and the name of the disease are output.

[0110] Furthermore, when performing machine learning, the input data may include subject attribute information, imaging site, hospital information, etc., along with dynamic and non-dynamic information. By using the classifier generated by this machine learning, it is possible to output the presence or absence of disease and the name of the disease based on the dynamic information, non-dynamic information, attribute information, imaging site, hospital information, etc., of the patient (subject) to be diagnosed.

[0111] As described above, the medical information management device 10 of this embodiment can promote the utilization of dynamic information by associating non-dynamic information, which users are more familiar with than dynamic information, with dynamic information. For example, by displaying non-dynamic images along with dynamic images on the display unit 23 of the client terminal 20, it is possible to provide information on how subjects with the same disease conditions as those in the dynamic images are captured in ways other than dynamic imaging.

[0112] Since dynamic imaging is a relatively new technology, comparing dynamic information with information obtained through conventional diagnostic methods other than dynamic imaging can help users recognize the usefulness of dynamic information, both in diagnostic and clinical research contexts. In the medical information management table 153, dynamic information is supported by objective facts such as non-dynamic information, which increases user trust in dynamic information and promotes its use.

[0113] The medical information management table 153 of the medical information management device 10 includes the correspondence between dynamic information and non-dynamic information obtained from normal subjects (subjects without disease), so that normal examples of dynamic and non-dynamic information can be provided to the user.

[0114] The medical information management table 153 of the medical information management device 10 contains the correspondence between dynamic and non-dynamic information obtained from subjects with a predetermined disease, so that abnormal examples of dynamic and non-dynamic information can be provided to the user for each disease.

[0115] Furthermore, the medical information management device 10 can manage dynamic and static information in association with at least one of the subject's disease information (presence or absence of disease, disease name), attribute information, imaging site information, and hospital information.

[0116] For subjects without disease, it is difficult to collect dynamic and non-dynamic information by performing multiple imaging or examinations on the same subject. Therefore, even if the subjects are different, it is important to manage the dynamic and non-dynamic information of subjects that meet the same disease criteria by associating them together.

[0117] Furthermore, the medical information management device 10 can output dynamic information obtained by performing dynamic radiography on a first subject that meets the conditions for a predetermined disease, based on a request from the client terminal 20, to the client terminal 20. Furthermore, the medical information management device 10 can output non-dynamic information obtained by performing imaging or examinations other than dynamic imaging on a second subject that meets the conditions for a predetermined disease, based on a request from the client terminal 20, to the client terminal 20. The medical information management device 10 can widely publish normal and abnormal examples of dynamic information in response to requests from client terminals 20 to view or download medical information, thereby promoting the dissemination of dynamic information.

[0118] The medical information management device 10 can publish medical information that corresponds to a request within the access range set for the user.

[0119] Furthermore, if each medical facility were to have its own AI algorithm for determining normal / abnormal conditions and disease names, it would be necessary to collect data and update the algorithm at each facility, which would result in variations in accuracy between facilities. In contrast, the medical information management device 10 collects medical information from multiple medical facilities, making it easier to collect large amounts of data compared to managing information separately for each medical facility. Furthermore, it eliminates differences in accuracy between medical facilities in disease diagnosis using AI algorithms based on medical information.

[0120] The above-described embodiments are examples of the medical information management device and medical information management program according to the present invention, and are not limited thereto. The detailed configuration and operation of each part constituting each device can also be modified as appropriate without departing from the spirit of the present invention.

[0121] For example, the data structure of medical information management table 153 (see Figure 4) is not limited to the illustrated example and can be changed according to the application.

[0122] Furthermore, in the medical information management device 10, instead of the medical information management table 153, a dynamic information management table for managing dynamic information and a non-dynamic information management table for managing non-dynamic information may be provided separately. Specifically, the dynamic information management table stores dynamic information (dynamic images, motion information, etc.) for each combination of disease information, attribute information, imaging site, and hospital information. The non-dynamic information management table stores non-dynamic information (medical images, findings, measured values, test results, etc.) for each combination of disease information, attribute information, imaging site, and hospital information. In this case, dynamic information that matches the search conditions (combinations of disease information, attribute information, imaging site, and hospital information) can be extracted from the dynamic information management table, and non-dynamic information that matches the search conditions can be extracted from the non-dynamic information management table, thereby providing dynamic and non-dynamic information associated with common search conditions to the client terminal 20.

[0123] In the above embodiment, a case was described in which the dynamic information includes both dynamic images and motion information. However, the dynamic information managed by the medical information management device 10 may not include motion information and may consist only of dynamic images (medical images obtained by dynamic imaging). By allowing users to understand the differences between normal and abnormal motion in dynamic images and to recognize the significance of dynamic images, it is possible to contribute to the widespread adoption of dynamic imaging.

[0124] Furthermore, the non-dynamic information managed by the medical information management device 10 may consist only of non-dynamic images (medical images obtained by imaging other than dynamic imaging). By comparing dynamic images with non-dynamic images that users are accustomed to seeing, it becomes easier to understand the difference between normal and abnormal movements in dynamic images.

[0125] Alternatively, the user management table 152 (see Figure 3) may be used to manage the scope of user access by dividing it into categories such as viewing and downloading.

[0126] Furthermore, users who utilize the medical information within the medical information management device 10 may be charged. For example, a pay-per-use system may be used, where the amount is determined according to the amount of medical information viewed or downloaded by the user (data volume, number of files, number of times, etc.), or a flat-rate system may be used within a predetermined period. Alternatively, charges may be applied to each medical facility to which the user belongs. Furthermore, charges may be applied separately for viewing and downloading.

[0127] Furthermore, the programs for executing each process in each device may be stored on a portable recording medium. Alternatively, a carrier wave may be used as the medium for providing the program data via a communication line. [Explanation of Symbols]
