Description

The present invention relates to a medical image management device, a medical image management system, and a program.

Conventionally, medical images include X-ray images, CT (Computed Tomography) scan images, MRI (Magnetic Resonance Imaging) images, etc., and medical imaging equipment installed in medical facilities such as hospitals (hereinafter referred to as "facilities") The patient is photographed and acquired as image data of a digital medical image. The photographed image data is stored by a medical image management system called PACS (Picture Archiving and Communication Systems) provided within the facility. Image data is required to be stored based on the Medical Practitioners Act, and if it is master data, it is permanently stored in the storage unit (for 5 years), and image data that is not master data is also stored in the storage unit.

Since the image data storage unit has the maximum storage capacity, a technique is known that automatically deletes the image data stored in the storage unit. For example, devices are known that delete image data from a storage unit when the storage unit reaches a predetermined capacity (see Patent Documents 1 and 2). Further, there is known a device that deletes image data from a storage unit when the image data stored in the storage unit is backed up to an external storage unit (see Patent Documents 1 and 3).

Further, there is known a device that deletes image data that is less likely to be referenced (used less frequently) from a storage unit due to the discharge of a patient as a subject or the like (see Patent Document 2 and Patent Document 4). Furthermore, a medical image processing system is known that does not delete image data acquired in an examination in which findings are described from a storage unit (see Patent Document 5).

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the illustrated example.

First, the device configuration of the medical image management system 1 of this embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a block diagram showing the configuration of a medical image management system 1 according to the present embodiment. FIG. 2 is a block diagram showing the functional configuration of the medical image management server 10. FIG. 3 is a block diagram showing the functional configuration of the medical image generation system 20A. FIG. 4 is a block diagram showing the functional configuration of the medical image management terminal 21. As shown in FIG.

The medical image management system 1 is a system that stores and manages image data of medical images across a plurality of facilities (medical facilities). As shown in FIG. 1, the medical image management system 1 includes a medical image management server 10 as a medical image management server, and medical image generation systems 20A, 20B, 20C, and 20D, and each device (system) communicates with each other. They are connected via network N1.

The medical image generation systems 20A, 20B, 20C, and 20D are installed inside the facilities of Hospital A, Hospital B, Clinic C, and Clinic D, respectively, and generate image data of medical images by photographing patients at each facility. It is a system that manages the Hospital A, Hospital B, Clinic C, and Clinic D are facilities affiliated with one group. In each facility, the installed modality (medical image capturing device) and whether the image data of the facility is permanently stored in the medical image management server 10 are arbitrarily set. For example, in the case where image data taken at clinic D is permanently stored in the medical image generation system 20D, there is no need for permanent storage in the medical image management server 10. Further, the number of facilities is not limited to four.

The medical image management server 10 and the medical image generation systems 20A, 20B, 20C, and 20D are connected via a communication network N1. The communication network N1 is a WAN (Wide Area Network) including the Internet.

The medical image management server 10 is a server device that is installed on a cloud and stores and manages image data of medical images across multiple facilities. If the stored image data is for permanent storage, the medical image management server 10 stores the image data for a permanent storage period (5 years from the examination), and if the stored image data is not for permanent storage, it stores the image data for a permanent storage period (5 years from the examination). In addition, the image data is provided to the medical image generation system of the requesting facility so that the image data is shared among a plurality of facilities.

By sharing image data, for example, hospital B does not have a mammography image capture device, hospital A has a mammography image capture device, and both mammography image data and image data from an ultrasound diagnostic device are used to monitor patients. It can also be used to diagnose cases. In the medical image generation system 20A, image data of a certain patient's mammography is photographed and transmitted to the medical image management server 10 and stored, and in the medical image generation system 20B, image data of an ultrasound image of the patient is photographed, Mammography image data of the patient is acquired from the medical image management server 10, and the acquired mammography image data and ultrasound image data are displayed, and the doctor at Hospital B diagnoses the patient.

Clinic C, which is a facility, cannot interpret certain types of image data (for example, PET (Positron Emission Tomography)-CT (Positron Emission Tomography) image data), so it uses an image interpretation service. In the image interpretation service, an image interpretation service provider interprets the image data requested for interpretation, generates an image interpretation report, and sends it to the requesting facility. For this reason, although not shown, a server device of an image interpretation service provider is connected to the communication network N1, and the server device receives the target image data, for example, when there is a request for image interpretation service from the medical image generation system 20C. A request is made to and received from the medical image management server 10, the received image data is interpreted, an interpretation report is created, and the report is sent to the medical image generation system 20C. Note that the server device of the image interpretation service provider does not transmit the image data of the medical image to the medical image management server 10. Furthermore, it is desired that the image data stored in the medical image management server 10 for use of the image interpretation service be deleted after the image interpretation is completed.

The facility is not limited to hospitals and clinics, but may be other facilities such as a medical examination vehicle. The examination car connects a PC (Personal Computer) inside the car to the communication network N1, transmits image data taken inside the car from the PC to the medical image management server 10, and also sends image data necessary for the examination to the medical image management server 10.

The modality 23 is at least one medical image capturing device, for example, a DR (Digital Radiography) device, which captures patient's X-ray image data as a medical image using an FPD (Flat Panel Detector). It is assumed that an image is taken and the X-ray image data is transmitted to the medical image management terminal 21 and stored. However, the modality 23 is not limited to DR, but may include a CR (Computed Radiography) device that uses an IP (Imaging Plate) to capture X-ray image data of a patient using X-rays as a medical image; CT imaging equipment that takes X-ray tomographic image data of a patient as a medical image, MRI imaging equipment that takes magnetic patient tomographic image data as a medical image, Ultrasound that takes ultrasound image data of a patient as a medical image. Other modalities such as diagnostic equipment may also be used. For example, assume that the modality 23 of hospital A includes a digital X-ray imaging device for mammography (mammography imaging device).

The imager 24 is a printer that prints on film, and performs printing by forming an image on the film in response to a print instruction for print information such as image data input from the client PC 25.

The client PC 25 is a desktop PC terminal device that has a viewer function for displaying medical images and is used for image interpretation by a user such as an image interpreting doctor. The control unit of the client PC 25 transmits a reference image data acquisition request to the medical image management terminal 21 in response to a user's operation input, and receives image data corresponding to the acquisition request from the medical image management terminal 21. The client PC 25 then displays the medical image on its own display unit based on the acquired image data.

Next, information stored in the storage unit 15 of the medical image management server 10 will be explained with reference to FIGS. 5(a) and 5(b). FIG. 5(a) is a diagram showing the facility information table 30. As shown in FIG. FIG. 5(b) is a diagram showing the image information table 40.

The medical image management server 10 includes a facility information table 30 that includes information regarding deletion of image data corresponding to hospitals A to clinic D as a plurality of facilities, and image information that includes information regarding image data received from hospitals A to clinic D. The table 40 is stored in the storage unit 15.

As shown in FIG. 5A, the facility information table 30 has items such as facility name 31, permanent storage 32, deletion priority 33, and deletion priority item 34. The facility name 31 is the name of the facility to which the medical image generation systems 20A to 20B included in the medical image management system 1 belong.

Permanent storage 32 is information indicating whether or not image data of the facility with facility name 31 is permanently stored in the medical image management server 10. The deletion priority 33 is information indicating the deletion priority for deleting image data in the medical image management server 10 at the facility with the facility name 31 that is not permanently stored in the permanent storage 32 . Regarding the order of deletion priority 33, for example, a plurality of facilities may be simply given an order (for example, the order of registration), or a facility that uses an image interpretation service may be given a higher order.

The deletion priority item 34 is information indicating the condition of the attribute item of the image data to be deleted in the facility with the facility name 31. The "old inspection date" of the deletion priority item 34 is information for deleting image data of an inspection date as an attribute item that is a predetermined period (for example, 90 days, 180 days) or more ago as a condition for the facility with the facility name 31. Similarly, "modality" is information for deleting image data of mammography, CT, and MRI, for example. Similarly, "old reception date" is information for deleting image data having a reception date as an attribute item that is a predetermined period (for example, 90 days, 180 days) or more ago as a condition in the medical image management server 10.

As shown in FIG. 5B, the image information table 40 includes items such as an image ID 41, an examination date 42, a reception date 43, a modality 44, and an image source 45. The image ID 41 is identification information of image data stored in the medical image management server 10. The examination date 42 is the examination date on which the image data of the image ID 41 was photographed. The reception date 43 is the reception date of the image data of the image ID 41 in the medical image management server 10.

Modality 44 is the type of modality 23 in which the image data of image ID 41 was photographed. The modalities 44 include mammography (mammography imaging device), ultrasound (ultrasound diagnostic device), DR (DR device), CR (CR device), CT (CT imaging device), MRI (MRI imaging device), and the like. The image source 45 is the source of the image data of the image ID 41 (the source of the image data in the medical image management server 10).

Next, the operation of the medical image management system 1 will be explained with reference to FIG. FIG. 6 is a flowchart showing image deletion processing.

In advance, the CPU 211 of the medical image management terminal 21 of the medical image generation systems 20A to 20D receives image data taken by the modality 23 from the modality 23 and stores it in the storage unit 215, and also transmits the medical image via the communication unit 217. It is assumed that the information is sent to the management server 10 and stored. Image data is transmitted from the medical image management terminal 21 to the medical image management server 10 by, for example, transmitting the selected image data at the timing when a user instructs selection and transmission of image data via the operation unit 12. The image data may be automatically transmitted at a predetermined timing (for example, at a predetermined date and time on the day following the examination date).

When receiving one piece of image data from the medical image generation systems 20A to 20D, the CPU 11 of the medical image management server 10 assigns a unique image ID to the image data, and identifies the examination date and modality from the tag information of the image data. , the current date is acquired as the reception date of the image data, and the facility name corresponding to the medical image generation system that is the source of the image data is acquired. Then, the CPU 11 sets the assigned or acquired image ID, examination date, reception date, modality, and facility name as one new record, and sets the image ID 41, examination date 42, reception date 43, and modality 44 in the image information table 40, respectively. , stored in the image source 45.

In the medical image management server 10, for example, when a predetermined date and time (for example, 3:00 a.m. in the middle of the night, avoiding the daytime hours when the medical image management server 10 is loaded) is a trigger, the CPU 11 controls the storage unit 15. Image deletion processing is executed in cooperation with an image deletion program read out from the computer and expanded into the RAM 13 as appropriate. The image deletion process is executed by, for example, a task scheduler of the medical image management server 10.

As shown in FIG. 6, the CPU 11 first determines whether the storage capacity of the storage unit 15 is equal to or larger than a predetermined capacity as a threshold for deleting image data (step S11). The predetermined capacity is, for example, a capacity that may cause a problem such as a decrease in the processing efficiency of the medical image management server 10. If the storage capacity is less than the predetermined capacity (step S11; NO), the image deletion process ends.

If the storage capacity is greater than or equal to the predetermined capacity (step S11; YES), the CPU 11 refers to the facility information table 30 stored in the storage unit 15 and determines whether there is a facility with the facility name 31 that the permanent storage 32 does not permanently store. (Step S12). If there are no facilities that are not to be permanently stored (step S12; NO), the image deletion process ends. The image data of the facility to be permanently stored is appropriately deleted from the storage unit 15 when five years or more have passed since the medical treatment (examination date), in a process different from the image deletion process.

If there is a facility that will not be permanently stored (step S12; YES), the CPU 11 refers to the facility information table 30 and selects the deletion priority 33 and deletion priority item corresponding to the facility name 31 of the facility that is not permanently stored acquired in step S12. 34 is acquired (step S13). Then, the CPU 11 selects (the facility name 31 of) the facility with the highest deletion priority 33 (the lowest number) acquired in steps S12 and S13 (step S14).

Then, the CPU 11 refers to the image information table 40 stored in the storage unit 15, and selects the examination date 42, reception date 43, or modality corresponding to the image source 45 of the facility name 31 of the facility selected in step S14 or S16. 44 determines whether there is image data with the image ID 41 that satisfies the conditions of the deletion priority item 34 of the facility (step S15). If there is no image data that satisfies the conditions of the deletion priority item 34 (step S15; NO), the CPU 11 selects a facility whose deletion priority level 33 obtained in steps S12 and S13 is the next highest (smallest number) after the selected facility. (facility name 31) is selected (step S16).

Then, the CPU 11 determines whether or not the facility (the facility name 31) selected in step S16 exists (step S17). If there is a selected facility (facility name 31) (step S17; YES), the process moves to step S15. If there is no selected facility (facility name 31) (step S17; NO), the image deletion process ends.

If there is image data that satisfies the conditions of the deletion priority item 34 (step S15; YES), the CPU 11 selects one of the image data of the image ID 41 that satisfies the conditions of the deletion priority item 34 of the selected facility acquired in step S15. is deleted from the storage unit 15, and the record of the image ID 41 of the deleted image data is deleted from the image information table 40 (step S18). In step S18, when there is a plurality of image data satisfying the condition, one image data is deleted among the plurality of image data, for example, in the order of image ID 41, inspection date 42, or reception date 43. Ru.

Then, the CPU 11 determines whether the storage capacity of the storage unit 15 is equal to or greater than a predetermined capacity similar to step S11 (step S19). If the storage capacity is equal to or greater than the predetermined capacity (step S19; YES), the process moves to step S12. If the storage capacity is less than the predetermined capacity (step S19; NO), the image deletion process ends.

As described above, according to the present embodiment, the medical image management server 10 manages image data in the storage unit 15 that stores image data of medical images received from a plurality of medical image management terminals 21 provided in a plurality of facilities. do. The medical image management server 10 includes a CPU 11 that automatically deletes image data from the storage unit 15 based on a facility information table 30 regarding deletion of image data of each facility.

Therefore, image data of medical images can be automatically and appropriately deleted according to a plurality of facilities.

Further, the CPU 11 determines whether the storage capacity of the storage unit 15 is greater than or equal to a predetermined capacity, and deletes the image data from the storage unit 15 if it is greater than or equal to the predetermined capacity. Therefore, image data can be deleted when the capacity is such that it is desirable to delete image data, and image data can be prevented from being deleted when deletion is not necessary, thereby reducing the processing load on the medical image management server 10.

The facility information table 30 also includes a permanent storage 32 indicating whether each facility permanently stores image data in the storage unit 15. Based on the permanent storage 32, the CPU 11 deletes from the storage unit 15 image data of facilities that are not to be permanently stored. Therefore, the image data of the facility to be permanently stored in the storage section 15 can be reliably permanently stored, and the image data of the facility that is not permanently stored in the storage section 15, which is likely to be unnecessary, can be prioritized and deleted from the storage section 15.

Furthermore, the facility information table 30 includes a deletion priority level 33 indicating the priority level for deleting image data of each facility that is not permanently stored. Based on the deletion priority 33, the CPU 11 prioritizes and deletes image data of facilities with a high deletion priority from the storage unit 15. Therefore, among the facilities that are not permanently stored in the storage section 15, image data of facilities with a high deletion priority can be deleted from the storage section 15 with priority.

Furthermore, the facility information table 30 includes a deletion priority item 34 indicating the condition of the attribute item of the image data to be deleted for each facility. Based on the deletion priority item 34, the CPU 11 deletes image data that satisfies the attribute item conditions from the storage unit 15. Therefore, image data that satisfies the attribute item conditions and is likely to be unnecessary can be deleted from the storage unit 15.

Further, the attribute item is the inspection date, reception date, or modality of the image data. Therefore, appropriate image data can be deleted from the storage unit 15 based on conditions of appropriate attribute items.

The medical image management system 1 also includes a medical image management server 10 and medical image management terminals 21 of a plurality of medical image generation systems 20A to 20D. Therefore, it is possible to configure a medical image management system 1 that can automatically and appropriately delete image data of medical images depending on a plurality of facilities.

Note that the description in the above embodiment is an example of a suitable medical image management device, medical image management system, and program according to the present invention, and the present invention is not limited thereto.

For example, in the above embodiment, the unit of deletion of image data is an image data unit, but the invention is not limited to this. For example, the unit of deletion of image data may be a series unit. A series is an attribute positioned below an examination, and includes an imaging region (chest, etc.), an imaging method (normal CR, CR using a contrast agent, etc.) within one examination.

Further, in the above embodiment, the medical image management terminal 21 is configured to transmit and store the image data of the medical image to the medical image management server 10 via the communication network N1, but the configuration is not limited to this. isn't it.
