Description

[Technical field]

[0001] The present invention relates to a medical image display device, a medical image display system, a medical image display method, and a program. [Background technology]

[0002] In recent years, the functions of medical facilities such as hospitals and clinics have become increasingly differentiated. As a result, the care cycle for a patient's illness (such as examinations, diagnosis, and treatment) is now spread across multiple medical facilities. Furthermore, with the development of cloud systems, technology for collectively managing data from multiple medical facilities in the cloud has advanced. However, at present, identification information (such as a patient ID) that identifies a patient is different for each medical facility, making it difficult to collectively grasp data on patients that exist across multiple medical facilities. As a result, there is a growing trend to manage patients using common identification information, such as a region ID that is unique within a region, My Number (registered trademark), or medical ID.

[0003] However, such common identification information is not yet widespread, and it is still common for each medical facility to manage patients using their own unique identification information (such as patient IDs).

[0004] For example, Patent Document 1 describes a medical image display device that identifies the same patient by using a so-called name matching technology to view data such as medical images of patients managed across medical facilities and regions. Name matching technology is a technology that searches for related patients similar to a search target patient, and displays patient information corresponding to the search target patient and the related patients in list form on a display means so that differences between the patient information can be compared. Patent Document 1 describes that the medical image display device displays a name matching list and uses the name matching list to identify the same patient in advance.

[0029] An embodiment of the present invention will be described below, however, the present invention is not limited to the illustrated example.

[0030] [Medical image display system] FIG. 1 shows the configuration of a medical image display system 1. The medical image display system 1 is composed of imaging devices 11 of multiple medical facilities A, B, ..., X, a medical image management device 12, and a medical image display device 13. The medical image display system 1 also includes a data management device 20. The devices constituting the medical image display system 1 are connected via a communication network N such as a LAN (Local Area Network), a WAN (Wide Area Network), or the Internet. The devices constituting the medical image display system 1 also comply with the HL7 (Health Level Seven) and DICOM (Digital Image and Communications in Medicine) standards. Therefore, communication between the devices is performed in accordance with HL7 and DICOM.

[0031] [Photographing device] The imaging device 11 is an image generating device such as an X-ray imaging device (DR, CR), an ultrasound diagnostic device (US), a CT, an MRI, etc. The imaging device 11 captures an examination target part of a patient as a subject based on examination order information transmitted from a RIS (Radiology Information System) (not shown) or the like, and generates a medical image as medical information.

[0032] In the medical image generated by the imaging device 11, for example, supplementary information (patient information, examination information, image ID, etc.) is written in the header of the image file in accordance with the DICOM standard. The medical image with the supplementary information is transmitted to the medical image management device 12 via a console (not shown) or the like. Note that the medical image may be transmitted from the console to an image analysis device, and the analyzed image after a predetermined analysis process is transmitted to the medical image management device 12.

[0033] [Medical image management device] The medical image management device 12 is, for example, a server constituting a PACS (Picture Archiving and Communication System). When the medical image management device 12 receives a medical image from the imaging device 11, the medical image management device 12 stores the medical image in a database in association with patient information, examination information, an image ID of the medical image, a facility ID of the medical facility, etc. Then, the medical image management device 12 transmits a copy of the stored medical image to the data management device 20.

[0034] [Medical image display device] The medical image display device 13 is a device that displays medical images captured in a specified examination. A block diagram showing the functional configuration of the medical image display device 13 is shown in Fig. 2. The medical image display device 13 is configured with a control unit 131, an operation unit 132, a display unit 133, a communication unit 134, a RAM (Random Access Memory) 135, a storage unit 136, etc. Each unit of the medical image display device 13 is connected by a bus 137.

[0035] (Control unit) The control unit 131 is configured with a CPU (Central Processing Unit) etc. The control unit 131 reads out a system program and various processing programs stored in the storage unit 136, and develops them in a work area formed in the RAM 135. Then, the control unit 131 controls each unit according to the programs.

[0036] (Operation unit) The operation unit 132 includes a keyboard having cursor keys, character input keys, various function keys, etc., and a pointing device such as a mouse. The operation unit 132 outputs instruction signals input by key operations on the keyboard or mouse operations to the control unit 131. The operation unit 132 may also include a touch panel formed so as to cover the display unit 133.

[0037] (Display) The display unit 133 is configured with a monitor such as an LCD (Liquid Crystal Display), etc. The display unit 133 displays various screens and the like according to instructions of a display signal input from the control unit 131.

[0038] (Communications Department) The communication unit 134 includes a LAN adapter, a router, a TA (Terminal Adapter), etc. The communication unit 134 transmits and receives data to and from an external device connected to a communication network.

[0039] (RAM) The RAM 135 forms a work area. The work area temporarily stores various data in various processes executed and controlled by the control unit 131. The data temporarily stored in the work area is, for example, various programs read from the storage unit 136, input or output data, parameters, etc.

[0040] (Storage part) The storage unit 136 is composed of a hard disk, a non-volatile semiconductor memory, etc. The storage unit 136 stores the system programs and various processing programs executed by the control unit 131, and data required for executing these programs. The storage unit 136 stores, for example, a search processing program P1, a search result display processing program P2, and a medical image display processing program P3.

[0041] {Search processing program} The search processing program P1 is a program that executes examination search processing and related patient search processing. The examination search processing is processing that searches and extracts examinations that match a predetermined search condition from the medical image management device 12. The related patient search processing is processing that searches and extracts second patients, who are related patients having personal identification information that matches the personal identification information of the target first patient, from the patient database 21.

[0042] {Search result display processing program} The search result display processing program P2 is a program that executes a patient search result display processing and an examination search result display processing. The examination search result display processing is a processing that displays a list of examinations extracted by the execution of the search processing program P1 in the worklist WL (see FIG. 4). Moreover, the related patient search result display processing is a processing that displays a list of related patients extracted by the execution of the search processing program P1 in the worklist WL.

[0043] {Medical image display processing program} The medical image display processing program P3 is a program for executing the medical image display processing, which is a process for acquiring medical images of an examination specified from the list of examinations displayed by the examination search result display processing from the medical image management device 12 or the medical image database 23, and displaying them on the viewer V (see FIG. 5).

[0044] [Data Management Device] Returning to Fig. 1, the data management device 20 is, for example, a virtual device provided in a cloud environment. The data management device 20 is connected to the medical image management devices 12 and the medical image display devices 13 of a plurality of medical facilities. The data management device 20 includes a patient database 21, an examination database 22, and a medical image database 23 corresponding to each medical facility. The data management device 20 stores the medical images received from each medical image management device 12 in the corresponding medical image database 23. The data management device 20 also transmits data of each database to the medical image display devices 13 based on communication from each medical image display device 13.

[0045] {Patient Database} The patient database 21 stores the personal identification information of patients from multiple medical facilities. The personal identification information is composed of multiple items (elements). The personal identification information includes, for example, patient ID, patient name (kanji, kana, alphabet), date of birth (age), sex, medical facility, and other patient information.

[0046] In addition, medical information such as medical record information and vital information may be associated with each piece of patient information in the patient database 21. The medical information is generated in the same medical facility as the patient information associated with the medical information.

[0047] {Testing Database} The examination database 22 stores examination specific information of examinations performed at multiple medical facilities. The examination specific information is composed of multiple items (elements). For example, the examination specific information includes an examination ID, a patient's name (in kanji, kana, or alphabet), date of birth, sex, medical facility, examination date, modality, and imaging site. In addition, the items of the examination specific information include a path of a medical image of the patient taken during the examination, which is stored in the medical image database 23.

[0048] {Medical image database} The medical image database 23 stores medical images captured by the imaging device 11 in examinations performed at multiple medical facilities and received from the medical image management device 12. The medical image database 23 stores supplementary information associated with each medical image. The supplementary information includes patient information, examination information, series information, image information, etc.

[0049] The patient information is information about a patient, and includes a patient ID, a patient name, a date of birth, an age, and a sex.

[0050] The study information is information related to a study, including a study instance UID, study date and time, and study description.

[0051] Series information is information about a series. Series information includes modality (CT, MRI, DR, CR, US, etc.), series instance UID, examination site, series number, and series description. Series instance UID is a unique ID for identifying a series. Series number is a number that indicates the order of series within the same examination, and may be used for display order, etc.

[0052] The image information is information about a medical image. The image information includes the image number, the image generation date and time, the shooting direction, the shooting start position, the image type, and the file path. The image number is a number indicating the number of the image in the same series. The shooting start position is a coordinate indicating the position where the examination (scan) started in an examination such as CT or MRI. The image type is information indicating whether the image is a slice image or a scout image in an examination such as CT or MRI. The file path is information indicating the storage location of the medical image in the medical image database 23.

[0053] [Medical image display processing] Next, the operation of the medical image display device 13 will be described. Fig. 3 is a flowchart showing medical image display processing executed by the medical image display device 13. The medical image display processing is realized by software processing or the like in cooperation with the control unit 131 and a program stored in the storage unit 136. The medical image display processing is started when the user starts the worklist WL.

[0054] First, the user inputs predetermined search conditions and presses the search button by operating the operation unit 132. Then, the control unit 131 executes the examination search process by the search process program P1 (step S101). Then, the control unit 131 acquires examination data of the own facility that satisfies the predetermined search conditions from the medical image management device 12.

[0055] The control unit 131 executes the examination search result display process by the search result display process program P2 (step S102). The control unit 131 causes the worklist WL to display a list of examinations that satisfy the specified search conditions by the examination search result display process. FIG. 4 shows an example of the worklist WL in which a list of examinations that satisfy the specified search conditions is displayed. In FIG. 4, a list of examinations for patients whose names start with "Sato" is displayed in the worklist WL as the specified search condition.

[0056] The control unit 131 accepts the designation of the first examination by a predetermined operation by the user (step S103). For example, in FIG. 4, the row of "Sato Masaru" whose patient ID is PT-A002 is clicked once to select it. Then, in this selected state, the same row is double-clicked again to specify the examination. The control unit 131 acquires the medical images of the first examination specified in this step from the medical image management device 12.

[0057] 3, the control unit 131 that has received the designation of the first examination executes related patient search processing by the search processing program P1 (step S104). Then, the control unit 131 acquires data of a second patient, who is a related patient having personal identification information similar to that of the first patient of the designated first examination, from the patient database 21.

[0058] In this embodiment, the control unit 131 executes the related patient search process by a so-called name matching search. The name matching search is a search method for searching for a related patient, which is a second patient having second individual identifying information that is individual identifying information similar to the first individual identifying information, based on first individual identifying information that identifies a first patient.

[0059] Here, the related patient search process based on the name matching search performed by the control unit 131 will be described. The name matching search includes, for example, searching for related patients stored in the patient database 21 of a first medical facility using patient information of a first patient stored in the patient database 21 of the first medical facility. The name matching search also includes searching for related patients stored in the patient database 21 of a second medical facility using patient information of a first patient stored in the patient database 21 of the first medical facility. Of course, the related patients searched for in the name matching search may be the same person as the search target patient.

[0060] In the name matching search, five items of the individual identifying information, for example, the patient's name (kanji, kana, alphabet), date of birth, and gender, are used as name matching conditions. Note that the search conditions, which items of the individual identifying information are to be used as name matching conditions, are stored in advance in the storage unit 136.

[0061] First, the control unit 131 compares the personal identification information of the search target patient with other patients for each item. Then, the control unit 131 adds the penalty value of the mismatched item to a reference value of "1" and calculates the reciprocal of the addition result to calculate the similarity between the patients.

[0062] For example, suppose that the names (kana), names (alphabet), and genders of patients match, but the names (kanji) and dates of birth do not match. Also, suppose that the penalty values ​​are set as follows: name (kanji), "5", name (kana), "1", name (alphabet), "3", date of birth, and "1". In this case, the similarity is calculated as follows: Similarity = 1 / {reference value + penalty value for name (kanji) + penalty value for date of birth} =1 / (1+5+3) =0.11

[0063] In addition, suppose that the names (in kanji), birth dates, and genders of the patients match, but the names (in kana) and names (in alphabet) do not match. Also, suppose that the penalty values ​​are set in the same way as above. In this case, the similarity is calculated as follows: Similarity = 1 / {reference value + penalty value for name (kana) + penalty value for name (alphabet)} =1 / (1+1+1) =0.33

[0064] As the name matching search, the control unit 131 calculates the similarity between the search target patient and other patients as described above, and extracts other patients whose similarity is equal to or greater than a predetermined value as related patients. In this way, the control unit 131 functions as a determination unit that determines whether or not there is a related patient who satisfies the name matching conditions. The control unit 131 also functions as a calculation unit that calculates the similarity between the first patient and the related patients. The patient information of the related patients extracted by the name matching search is stored in RAM 135.

[0065] The control unit 131 may set items other than the above five items as the matching conditions. For example, the modality of the imaging device may be included in the matching conditions. Alternatively, the control unit 131 may include the imaging site of the medical image in the matching conditions. Furthermore, the items to be included in the matching conditions and the method of determining whether or not there is a related patient in the matching search may be appropriately changeable by a user operation. In this way, the control unit 131 functions as a matching condition setting unit that sets the matching conditions in the patient database 21.

[0066] As described above, data related to the modality of the imaging device and the imaging site of the medical image may be stored as examination information in the examination database 22. Alternatively, the control unit 131 may function as an identifying unit that identifies such information from the medical image stored in the medical image database 23 by the viewer V or the worklist WL.

[0067] The control unit 131 determines whether or not there is a related patient in the patient database 21 (step S105). If there is no related patient in the patient database 21 (step S105; No), the control unit 131 executes the medical image display processing program P3. Then, as shown in Fig. 5, the control unit 131 causes the viewer V to display only the medical images of the searched patient (step 106).

[0068] On the other hand, if a related patient exists in the patient database 21 (step S105; Yes), the control unit 131 executes the medical image display processing program P3. Then, as shown in Fig. 6, the control unit 131 causes the viewer V to display the medical image of the search target patient and presence information E indicating that a related patient exists in the patient database 21 (step S107). Thus, in this embodiment, the control unit 131 functions as a display control unit that displays the presence information E.

[0069] In this embodiment, the presence information E is, for example, a button including characters, but is not limited to this. The presence information E may be, for example, a predetermined symbol or mark.

[0070] The control unit 131 accepts a predetermined operation (step S108). For example, in this embodiment, the predetermined operation is clicking on the presence information E. When the predetermined operation is accepted (step S108; Yes), the control unit 131 executes the search result display processing program P2. Then, as shown in FIG. 7, the control unit 131 displays a list of patient information of related patients stored in the RAM 135 in the work list WL (step S109).

[0071] The control unit 131 accepts a predetermined operation on the worklist WL (step S110). In this embodiment, the predetermined operation is, for example, a double click to specify one related patient.

[0072] When a predetermined operation on the worklist WL is accepted (step S110; Yes), the control unit 131 uses the search processing program P1 to obtain a list of examinations for the one related patient from the examination database 22. An example of the examination list is shown in Fig. 8. Then, the control unit 131 executes the search result display processing program P2 to display a list of examinations for the specified one related patient in the worklist WL (step S111).

[0073] The control unit 131 receives a predetermined operation on the work list WL (step S112). In this embodiment, the predetermined operation is, for example, a double click to specify the second examination.

[0074] When a predetermined operation on the worklist WL is accepted (step S112; Yes), the control unit 131 executes the medical image display processing program P3. Then, the control unit 131 causes the viewer V to display both the medical image of the first examination of the search target patient and the medical image of the second examination of the related patient specified in step S112 (step S113).

[0075] If the test specified in step S112 was performed in a medical facility different from the test specified in step S103, it is preferable to display a warning C in step S113. An example of such a display is shown in Fig. 9. If the search target patient and the related patient are patients in different facilities, they may be different patients even if they have similar individual identification information. Therefore, by using such a configuration, it is possible to prevent the user from noticing that the patients are different.

[0076] [Effects of this embodiment] As described above, the medical image display device 13 according to this embodiment includes a display unit 133 that displays a medical image of a first patient. The medical image display device 13 also includes a communication unit 134 that communicates with a patient database 21 that stores personal identification information of patients generated in a plurality of medical facilities. The display unit 133 displays the presence information E when a second patient, who is a related patient having personal identification information similar to the personal identification information of the first patient, is registered in the patient database 21. According to this configuration, the user can determine whether or not it is necessary to execute a process to search for related patients depending on whether the presence information E is displayed on the display unit 133. Therefore, it is possible to prevent the search process for related patients from being executed even when there is no related patient, and the user's work efficiency is not reduced.

[0077] [Other configurations] The above description of the embodiment is an example of the medical image display device according to the present invention, and is not limited thereto. The detailed configuration and detailed operation of each part constituting the device can be appropriately changed without departing from the spirit of the present invention.

[0078] For example, in the above embodiment, when there is no related patient, only medical images of the search target patient are displayed in the viewer V, but this is not limited to this. For example, as shown in Fig. 10, the control unit 131 may display non-existence information NE indicating that there is no related patient in the viewer V. This configuration makes it easier for the user to understand that no related patient was found after the name matching search was performed.

[0079] In the above, the data management device 20 is configured to have a database corresponding to each medical facility, but this is not limited to the above. That is, a single patient database 21, examination database 22, and medical image database 23 may be configured to centrally manage the data of all connected medical facilities.
