[0020] Embodiment 1 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of a patient follow-up system 1 according to Embodiment 1. The patient follow-up system 1 according to Embodiment 1 includes a data generation device 10 and a patient interface device 20. The patient follow-up system 1 analyzes test information Cinfo obtained from tests performed on a patient at a medical institution, and generates for the patient primary presentation information ARf that serves as a digest of the test results, and secondary presentation information ARs that includes additional information for learning more about the results included in the primary presentation information ARf. Then, the patient follow-up system 1 according to Embodiment 1 presents the primary presentation information ARf to the patient through the medical institution, and presents the secondary presentation information ARs to the patient using the test identification information IDc included in the primary presentation information ARf as a key. Therefore, in FIG. 1, in order to make the configuration of the patient follow-up system 1 easier to understand, operations related to the medical institution and the patient, who are users of the patient follow-up system 1, are illustrated.

[0021] The primary presentation information ARf described below is an example of information provided to patients by medical institutions as printed paper; however, the primary presentation information ARf may also be electronic data or displayed on a website.

[0022] The patient follow-up system 1 according to Embodiment 1 can be used for various types of examination information, but in the following description, we will use PET (positron emission tomography) imaging diagnostic examinations as an example. In other words, the patient follow-up system 1 according to Embodiment 1 is envisioned as a system in which a medical institution acquires examination information from an imaging diagnostic device that generates examination images during an examination of a patient, and the target imaging diagnostic device is not limited to PET.

[0023] The data generation device 10 performs the following processes: a first receiving process that receives examination information Cinfo, which includes examination images generated by an imaging diagnostic device used by a medical institution for examinations of patients; an identification information generation process that generates examination identification information IDc to identify the examination from the examination information Cinfo; and a presentation information generation process that generates score information, which is a score obtained by scoring the magnitude of the difference between the examination information and reference state information indicating a pre-prepared reference state; examination identification information IDc; linked primary presentation information ARf; additional information for a more detailed understanding of the reference state and score information; and linked secondary presentation information ARs, which includes the examination identification information IDc.

[0024] Here, reference status information can refer to a variety of things, such as statistical data obtained by statistically processing a vast amount of data from past examinations, guideline values ​​presented by medical institutions, public institutions, academic societies, etc., past data of patients, one of the assumed disease model data, or a combination of multiple data.

[0025] The patient interface device 20 performs a second receiving process that receives examination identification information IDc linked to the primary presentation information ARf, and a secondary presentation information presentation process that presents secondary presentation information ARs corresponding to the received examination identification information IDc to the patient.

[0026] Here, the processing in the data generation device 10 and the patient interface device 20 can be implemented using either dedicated hardware for each process or programs executed on a computer to implement each process. However, the following explanation will describe an example where the processing is implemented using a program. Furthermore, the following explanation will describe an example where the data generation device 10 has a data management device 30 and a data analysis device 40, and the patient interface device 20 has a data display device 50. In addition, an example will be described in which the data management device 30, data analysis device 40, and data display device 50 are each implemented as independent computers, programs are executed on each computer, and the patient follow-up system 1 is realized by interconnecting the data management device 30, data analysis device 40, and data display device 50 via a network. However, each process in the patient follow-up system 1 can be performed by interconnecting one or more computers via a network and distributing the processing required by the patient follow-up system 1 among the computers, and the number of computers and their locations are not relevant.

[0027] The data management device 30 includes an ID issuing unit 31, a medical institution-side linking management unit 32, a presentation information issuing unit 33, and a storage unit 34. The ID issuing unit 31 is a processing block that operates independently of the medical institution-side linking management unit 32, the presentation information issuing unit 33, and the storage unit 34. The ID issuing unit 31 issues medical institution identification information IDm to the medical institution when the medical institution registers to use the patient follow-up system 1 before the medical institution starts using it.

[0028] The medical institution-side linking management unit 32 performs a first receiving process in which it receives examination information Cinfo, which includes examination images generated by an imaging diagnostic device used by the medical institution for examinations of patients, and an identification information generation process in which it generates examination identification information IDc to identify the examination from the examination information Cinfo. Specifically, in the first receiving process, the medical institution-side linking management unit 32 receives medical institution identification information IDm along with the examination information Cinfo. In addition, in the identification information generation process, the medical institution-side linking management unit 32 generates examination identification information IDc based on the examination additional information contained in the examination information Cinfo. Furthermore, the medical institution-side linking management unit 32 links the primary presentation information ARf, the medical institution report ARm, the examination identification information IDc, and the medical institution identification information IDm, which are among the analysis results generated based on the examination information Cinfo and are presented to the medical institution, and stores them in the storage unit 34. The storage unit 34 is a storage device for storing information for a long period of time.

[0029] Furthermore, the medical institution-side linking management unit 32 does not store the examination information Cinfo received from the medical institution long-term, but transmits it to the data analysis device 40. Additional information in the examination information Cinfo, if the examination information Cinfo is image information generated by a PET scan, includes a lot of information for data linking between medical institutions, patient information, and other information to identify the examination and its conditions. It is preferable for the medical institution-side linking management unit 32 to delete this additional information after generating the examination identification information IDc.

[0030] The presentation information issuing unit 33 performs a presentation information generation process that generates primary presentation information ARf from the examination information, which is created by linking score information, which is a score obtained by scoring the magnitude of the difference between the standard state information indicating a pre-prepared standard state and the examination information, with examination identification information IDc, and secondary presentation information ARs, which is created by linking additional information for a more detailed understanding of the examination image and score information with examination identification information. More specifically, the presentation information issuing unit 33 generates primary presentation information ARf and secondary presentation information ARs from the analysis result AR generated by the analysis process on the examination information Cinfo performed by the data analysis device 40. In addition to primary presentation information ARf and secondary presentation information ARs, the presentation information issuing unit 33 may also generate a medical institution report ARm, which corresponds to primary presentation information ARf and includes image data contained in the examination information Cinfo, and links the examination identification information IDc to this report.

[0031] The additional information is reference and comparative information added to the primary presentation information (ARf). Examples of additional information include past data from the same patient, comparisons with others of the same age, typical disease cases, and results of combined analyses with other data. The additional information may also include academic findings, advice for symptom improvement, and information on medical institutions. It is preferable that the information included as additional information be presented hierarchically according to the patient's requests.

[0032] The data analysis device 40 performs analysis on the inspection information Cinfo and generates the analysis result AR. The data analysis device 40 has a data analysis unit 41 and an information erasure unit 42. The data analysis unit 41 performs analysis on the inspection information Cinfo and generates the analysis result AR. At this time, the data analysis unit 41 also associates the inspection identification information IDc, which is linked to the inspection information Cinfo, with the analysis result AR. The analysis performed by the data analysis unit 41 is, for example, to statistically process the difference between the reference image information included in the pre-prepared reference state information and the inspection information Cinfo, and to store the deviation value of the difference as a score value in the analysis result AR. In addition, the data analysis unit 41 divides the inspection image to be analyzed into multiple regions and calculates the score value for each region.

[0033] The information erasure unit 42 deletes the completed inspection information Cinfo from the data analysis device 40. The information erasure unit 42 may also have a function to delete the analysis result AR from the data analysis device 40.

[0034] The data display device 50 performs a second receiving process to receive examination identification information IDc associated with the primary presentation information ARf, and a secondary presentation information presentation process to present secondary presentation information ARs corresponding to the received examination identification information IDc to the examinee.

[0035] The data display device 50 includes an ID issuing unit 51, a patient-side linking management unit 52, a storage unit 53, and an information presentation unit 54. The ID issuing unit 51 issues patient identification information IDu to the patient when user registration is performed before the patient begins using the patient follow-up system 1. However, if there is no need to refer to past examination history, the system can be configured not to use patient identification information IDu.

[0036] In the patient follow-up system 1, a QR code (registered trademark) that can read the test identification information IDc is attached to the primary presentation information ARf. When the patient accesses the patient follow-up system 1, they obtain the test identification information IDc by reading the QR code (registered trademark) on the primary presentation information ARf. Then, the patient-side linking management unit 52 uses the patient identification information IDu and test identification information IDc transmitted by the patient to link the patient identification information IDu to the secondary presentation information ARs. As a result, the test identification information IDc and patient identification information IDu are linked to the secondary presentation information ARs.

[0037] The storage unit 53 is, for example, a storage device capable of storing data for a long period of time, such as a hard disk. The storage unit 53 stores secondary presentation information ARs transmitted from the data management device 30, examination identification information IDc and patient identification information IDu linked to the secondary presentation information ARs.

[0038] The information presentation unit 54 reads out the secondary presentation information ARs based on the examinee identification information IDu and test identification information IDc transmitted from the examinee-side terminal and presents it to the examinee. The information presentation unit 54 presents the secondary presentation information ARs to the examinee in a web page format or an electronic document format. In addition, the content of the secondary presentation information ARs to be presented to the examinee is switched in stages based on a request from the examinee.

[0039] Note that in the examinee follow-up system 1, a plurality of pieces of test identification information IDc can be associated with one piece of medical institution identification information IDm. In the examinee follow-up system 1, a plurality of pieces of test identification information IDc can be associated with one piece of examinee identification information IDu. In addition, in the examinee follow-up system 1, when a medical institution cancels the use contract of the examinee follow-up system 1, the medical institution-side association management unit 32 deletes the test identification information IDc associated with the medical institution identification information IDm, the primary presentation information ARf associated with the test identification information IDc, and the medical institution report ARm from the data management device 30. In the examinee follow-up system 1, when the examinee cancels the use of the examinee follow-up system 1, the examinee-side association management unit 52 deletes the secondary presentation information ARs associated with the examinee identification information IDu. Note that in the examinee follow-up system 1, when the examinee cancels the use of the examinee follow-up system 1, the examinee-side association management unit 52 can also delete only information related to the examinee identification information IDu. In this case, if the examinee possesses the test identification information IDc when resuming the use of the examinee follow-up system 1, it is also possible to re-associate the secondary presentation information ARs with the examinee identification information IDu.

[0040] Here, one of the features of the patient follow-up system 1 according to Embodiment 1 is that it generates primary presentation information ARf and secondary presentation information ARs. Therefore, the primary presentation information ARf and secondary presentation information ARs will be explained in detail. In the following explanation, only characteristic parts of the primary presentation information ARf and secondary presentation information ARs will be shown, but various other examples of primary presentation information ARf and secondary presentation information ARs are also conceivable. Furthermore, Figures 2 and 3 show an example in which brain glucose metabolism read from PET images is used as a case shown to the patient, and information related to brain glucose metabolism is presented to the patient.

[0041] Figure 2 shows an example of primary presentation information output by the patient follow-up system according to Embodiment 1. The primary presentation information ARf shown in Figure 2 is given to the patient, for example, in the form of a printed copy on paper. The primary presentation information ARf shown in Figure 2 includes the judgment level calculated as an analysis result ("Your Judgment" in Figure 2), a radar chart plotting the score information included in the analysis result for each brain region, and a functional description for each brain region along with the corresponding score information. In the example shown in Figure 2, the examination identification information IDc (patient ID in Figure 2) is linked to the primary presentation information ARf using both a QR code (registered trademark) and text. Thus, the primary presentation information ARf only shows the patient's own score information and judgment level information. With this information alone, it is difficult for the patient to determine the actual level of healthiness of their symptoms. Therefore, if the patient wants to know more about their healthiness level, they can access the data display device 50 using this QR code (registered trademark) or text information to view the secondary presentation information ARs shown in Figure 3. On the other hand, for patients who are considered to have few problems, such as those whose "judgment" in the primary presentation information ARf is A, it is expected that they will have little motivation to view the secondary presentation information ARs.

[0042] Figure 3 shows an example of secondary presentation information output by the patient follow-up system according to Embodiment 1. As shown in Figure 3, the secondary presentation information ARs include the examination image obtained from the examination of the patient, a comparative examination image included in the additional information, a radar chart corresponding to the examination image, and a radar chart corresponding to the comparative examination image. The examination image and comparative examination image are displayed with images colored according to the magnitude of the score value for each predetermined brain image region, for each judgment level, to visually present the patient's health status. In the example shown in Figure 3, the comparative examination image is an average examination image obtained by statistically processing data obtained from other patients of the same age as the patient. In this way, by presenting the average state of other test takers in a comparable manner to the patient's examination image, the patient can understand in more detail what their own test results mean. Furthermore, in order to show the patient a large amount of information in stages in the information presentation unit 54 of the data display device 50, the secondary presentation information ARs may include a button BTN1 to return to previously displayed information and a button BTN2 to refer to the next information.

[0043] When button BTN2 is selected, the information display unit 54 switches the content of the information it presents, for example, as additional information, according to the patient's assessment level. For example, for patients with assessment levels A or B, the information display unit 54 may present information on exercise and diet to maintain good health, or present papers explaining the relationship between brain glucose metabolism and dementia. For patients with assessment levels C or D, the information display unit 54 may present papers explaining the relationship between brain glucose metabolism and dementia, or information on medical institutions, to encourage them to seek medical attention. The hierarchical information presented by the information display unit 54 is included in the secondary information ARs.

[0044] Next, the operation of the patient follow-up system 1 according to Embodiment 1 will be described. In the following description, the operation of the generation process of primary presentation information ARf and secondary presentation information ARs, which are one of the features of the patient follow-up system 1, and the presentation process of secondary presentation information ARs to the patient will be described.

[0045] Figure 4 shows a sequence diagram illustrating the operation of the data generation device 10 of the examinee follow-up system according to Embodiment 1. As shown in Figure 4, in the data generation device 10, the medical institution terminal transmits the examination information Cinfo together with the medical institution identification information IDm (step S10), and these are received by the data management device 30 (step S20). Then, the medical institution-side linking management unit 32 generates the examination identification information IDc from the received information (step S21). Subsequently, the medical institution-side linking management unit 32 transmits the examination information Cinfo and the examination identification information IDc to the data analysis unit 41 as an analysis command (step S22).

[0046] The data analysis unit 41 performs an examination information analysis process to analyze the received examination information Cinfo and generate the analysis result AR (step S30). Subsequently, the data analysis unit 41 links the analysis result AR to the examination identification information IDc and transmits it to the medical institution-side linking management unit 32 (step S31). In addition, the data analysis device 40 erases the examination information Cinfo using the information erasure unit 42.

[0047] The medical institution-side linking management unit 32 receives the analysis result AR from the data analysis unit 41 (step S23) and generates primary presentation information ARf based on the analysis result AR (step S24). The medical institution-side linking management unit 32 also generates secondary presentation information ARs and a report ARm for medical institutions based on the analysis result AR (steps S25, S26). The medical institution-side linking management unit 32 then transmits the primary presentation information ARf and the report ARm for medical institutions to the medical terminal (steps S27, S28). The medical institution-side linking management unit 32 also transmits the secondary presentation information ARs to the data display device 50 (step S29). The medical institution receives the primary presentation information ARf and the report ARm for medical institutions (steps S11, S12), provides the primary presentation information ARf to the patient on paper or as digital data, and the patient accesses the data display device 50 using the examination identification information IDc contained in the primary presentation information ARf, thereby starting the operation of the patient interface device 20.

[0048] Figure 5 shows a sequence diagram illustrating the operation of the examinee interface device of the examinee follow-up system according to Embodiment 1. As shown in Figure 5, when viewing secondary presentation information ARs, the examinee first reads the examination identification information IDc using the QR code (registered trademark) attached to the primary presentation information ARf (step S40). Subsequently, the examinee transmits the examination identification information IDc and examinee identification information IDu to the data display device 50 using the examinee terminal or the like (step S41).

[0049] Upon receiving the examination identification information IDc and the patient identification information IDu, the data display device 50 uses the patient-side linking management unit 52 to link the secondary presentation information ARs with the patient identification information IDu using the examination identification information IDc as the key (step S50). This step S50 can be omitted for subsequent accesses using the same examination identification information IDc.

[0050] Then, using the user interface screen displayed on the patient's terminal, the patient makes a transmission request to the data display device 50 to display secondary presentation information ARs (step S43). At this time, the patient identification information IDu is included in the transmission request from the patient's terminal to the data display device 50. The data display device 50 then transmits the secondary presentation information ARs to the patient's terminal according to the request (step S51). When the patient's terminal receives the secondary presentation information ARs, it displays the received secondary presentation information ARs on the screen (step S44). After that, steps S43, S51, and S44 are repeated until the patient operates the patient's terminal and there are no more requests for other secondary presentation information ARs (step S45).

[0051] As described above, in the patient follow-up system 1 according to Embodiment 1, the data generation device 10 generates primary presentation information ARf, which is a summary of the judgment level (level indicating healthiness) calculated from the patient's score value calculated by analyzing the examination information Cinfo, and simple information such as a radar chart created from the score value and an explanation of the body part to be judged, and secondary presentation information ARs, which presents as additional information how the score value etc. would change if the patient were at a different healthiness level, and the secondary presentation information ARs is presented only to patients who are interested in their own healthiness. In this way, the patient follow-up system 1 according to Embodiment 1 can provide information tailored to the interests of the examinee.

[0052] Furthermore, in the examinee follow-up system 1 according to Embodiment 1, by providing primary presentation information ARf and secondary presentation information ARs in different media, the amount of information and information flexibility of the secondary presentation information ARs can be increased compared to the primary presentation information ARf, making it possible to appropriately respond to the diverse needs of examinees.

[0053] Furthermore, by displaying secondary information ARs in stages, it is possible to present different content to patients depending on their level of judgment, for example. This makes it possible to efficiently encourage behavioral changes in patients, such as prompting preventive actions to improve their health status or connecting them with medical institutions. In addition, the secondary information ARs can also display images of the patient's body generated from the examination information Cinfo. This makes it possible to further encourage behavioral changes in patients by increasing their interest and engagement.

[0054] Furthermore, since the data display device 50 deletes the examination information Cinfo or additional information contained within the examination information Cinfo after generating the analysis result AR, it is not necessary to operate it as a specific device that is legally required to have a certain level of retention period or measures to prevent information leakage, thus making it possible to reduce the management costs of the patient follow-up system 1.

[0055] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. [Explanation of Symbols]
