Description

The embodiments of the present invention relate to a medical data file generation device, a medical data file generation system, and a medical data file generation program.

Acquisition of medical images by various examination devices (hereafter referred to as modality devices) used in the medical field is an indispensable technology in modern medical care because it enables us to see the inside of the body and make a diagnosis without damaging the body. It has become. For example, a doctor or the like sets imaging conditions for a modality device according to a diagnostic purpose, and diagnoses a patient's condition using medical images acquired based on the set imaging conditions. There is also a method of performing value-added diagnosis such as follow-up diagnosis using a plurality of medical images including newly acquired medical images and previously acquired medical images.

By the way, with the development and improvement in performance of modality devices, the amount of data of acquired medical images tends to increase. For this reason, it is not possible to store all medical images in a local database. For example, medical images that have been taken for a long time are transferred from the local database to the remote database because they are viewed less frequently. .

However, in an operation in which medical images are stored in either a local database or a remote database, the medical image desired by a doctor may not exist in the local database when required. In such a case, it is necessary to acquire medical images from a remote database at the request of the doctor, so the doctor delays the start of diagnosis by the time required for the transfer of the medical images and the data processing of the transferred medical images. There must be.

For example, in applications such as displaying a plurality of images side by side, the definition file 3142 includes conditions set by the user. Processing circuitry 313 searches and collects images and objects that meet the conditions from remote database 61 .

The communication interface 315 performs data communication with the hospital information system 10 , the radiology department information system 20 , the medical image diagnostic apparatus 40 , the communication terminal 50 and the storage server 60 . The communication interface 315 performs data communication, for example, in compliance with a preset known standard.

Note that the server device 31 may have an input interface. The input interface receives various input operations from the user, converts the received input operations into electrical signals, and outputs the electrical signals to the processing circuit 313 . The input interface is connected to input devices such as a mouse, keyboard, trackball, switch, button, joystick, touch pad, and touch panel for inputting instructions by touching the operation surface.

Any display such as a CRT (Cathode Ray Tube) display, a liquid crystal display, an organic EL display, an LED display, a plasma display, or the like can be used as appropriate for the display.

The processing circuit 313 shown in FIG. 2 executes the medical data file generation program stored in the memory 314, thereby realizing functions corresponding to the executed program. For example, the processing circuitry 313 functions as a control function 3131, a determination function 3132, a collection function 3133, and a generation function 3134 by executing a medical data file generation program. In this embodiment, the case where the control function 3131, the determination function 3132, the collection function 3133, and the generation function 3134 are realized by a single processor will be described, but the present invention is not limited to this. For example, a processing circuit may be configured by combining a plurality of independent processors, and the control function 3131, the determination function 3132, the collection function 3133, and the generation function 3134 may be implemented by each processor executing a program.

The control function 3131 is a function that controls the overall processing of the server device 31 as the local database 311 . Specifically, for example, in the control function 3131 , the processing circuit 313 causes the memory 314 to store the medical image data transmitted from the medical image diagnostic apparatus 40 . In addition, the processing circuit 313 stores the identification information of some of the medical image data stored in the memory 314 and transfers the substance to the storage server 60 , for example.

The determination function 3132 refers to the definition file 3142 stored in the memory 314 and determines whether or not the necessary medical data are available in the local database 311, and is an example of determination means. Specifically, for example, the processing circuit 313 reads the definition file 3142 from the memory 314 in the determination function 3132 . The processing circuit 313 determines whether or not the medical data defined in the read definition file 3142 are available in the local database 311 .

The collecting function 3133 is a function for collecting medical data from the remote database 61 constructed in the storage server 60, and is an example of collecting means. Specifically, for example, in the collection function 3133 , when at least part of the medical data defined in the definition file 3142 does not exist in the local database 311 , the processing circuit 313 retrieves the non-existing medical data from the remote database 61 . collect.

The generating function 3134 is a function of generating a medical data file from acquired medical data, and is an example of generating means. Specifically, for example, in the generating function 3134, the processing circuit 313 generates a medical data file based on the necessary medical data if the local database 311 has the necessary medical data. That is, the processing circuit 313 generates a medical data file from the medical data acquired from the local database 311, the medical data collected from the remote database 61, and the newly acquired medical data.

Next, an example of the operation of the server device 31 as a medical data file generation device configured as described above will be described in detail according to the processing procedure of the processing circuit 313. FIG.
FIG. 3 is a flow chart showing an example of the operation when the processing circuit 313 of the server device 31 shown in FIG. 2 generates a medical data file. Also, FIG. 4 is a schematic diagram for explaining the operation shown in FIG. In the description of FIG. 4, the medical image diagnostic apparatus 40 generates medical image data A and then generates medical image data B for the same patient. Supplementary information is added to the medical image data A and B generated by the medical image diagnostic apparatus 40 .

First, the server device 31 of the medical image management system 30 receives medical image data A generated by the medical image diagnostic apparatus 40 . When the processing circuit 313 of the server device 31 receives the medical image data A, the control function 3131 stores the received medical image data A in the memory 314 (step S31).

Processing circuitry 313 executes decision function 3132 when the number of medical image data stored in memory 314 increases, ie, when medical image data A is stored in memory 314 . In the determination function 3132, the processing circuit 313 reads out the definition file 3142 in which the medical image data A is listed as necessary medical data from the memory 314 (step S32).

The definition file 3142 read in FIG. 4 defines, for example, medical data necessary for generating a medical image data file for follow-up observation using subtraction images. In FIG. 4, "X" represents a medical image data file X for follow-up observation using subtraction images. In FIG. 4, the medical data required to create the medical image data file X are defined as "A", "B", "C", and "D".

In FIG. 4, "A" represents medical image data acquired on the current day, for example, based on the order information of "no contrast agent". The incidental information of the medical image data A includes examination date, patient ID, contrast agent information of "no contrast agent", and the like. “B” represents medical image data for the same patient acquired on the current day, for example, based on the order information “with contrast medium”. The supplementary information of the medical image data B includes examination date, patient ID, contrast medium information indicating "contrast medium present", and the like. "C" represents the medical image data for the same patient acquired in the past based on the order information of "no contrast medium". The supplementary information of the medical image data C includes examination date, patient ID, contrast medium information indicating "no contrast medium", and the like. "D" represents medical image data for the same patient acquired in the past based on the order information "with contrast agent". The incidental information of the medical image data D includes examination date, patient ID, contrast medium information indicating "contrast medium present", and the like.

After reading the definition file 3142, the processing circuit 313 refers to the definition file 3142 and determines that the medical image data B, C, and D are medical image data further necessary to generate the medical image data file X. . The processing circuit 313 searches the local database 311 for the medical image data B, C, and D (step S33). In FIG. 4, medical image data B is generated from this by the medical image diagnostic apparatus 40 . The medical image data C and D are managed by the remote database 61, and identification information is stored in the local database 311. FIG. That is, the local database 311 does not store the medical image data B, C, and D, but stores the identification information of the medical image data C and D. FIG. The identification information includes information that enables identification of the medical image data, address information of the database in which the medical image data is stored, and the like.

After searching the local database 311, processing circuitry 313 determines whether medical image data needs to be acquired (step S34). In FIG. 4, since the identification information of the medical image data C and D is stored in the local database 311, the processing circuit 313 determines that it is necessary to collect the medical image data C and D from the remote database 61 (step Yes in S34).

Upon determining that medical image data needs to be acquired, processing circuitry 313 performs acquisition function 3133 . In the acquisition function 3133, the processing circuit 313 refers to the identification information stored in the local database 311 and obtains the address of the remote database 61 storing the medical image data C and D. FIG. The processing circuit 313 accesses the remote database 61 using the obtained address, reads the medical image data C and D from the remote database 61, and stores the read medical image data C and D in the memory 314 (step S35).

After storing the medical image data C and D in the memory 314, the processing circuit 313 waits to execute the generating function 3134 until receiving the remaining medical image data, that is, the medical image data B (step S36). Further, in step S34, if there is no need to collect medical image data from the remote database 61, that is, if the medical image data C and D are stored in the local database 311 (No in step S34), the processing circuit 313 The process is shifted to step S36.

When medical image data A is generated by imaging without a contrast agent by the medical image diagnostic apparatus 40, a contrast agent is administered to the patient. The medical image diagnostic apparatus 40 takes an image of the patient to whom the contrast medium has been administered, and generates medical image data B. FIG. The medical image diagnostic apparatus 40 transmits the generated medical image data B to the medical image management system 30 .

When receiving the medical image data B, the processing circuit 313 of the server device 31 stores the received medical image data B in the memory 314 . When the medical image data B is stored in the memory 314 , that is, when all the medical image data defined in the definition file 3142 are ready, the processing circuitry 313 executes the generation function 3134 . In the generation function 3134, the processing circuit 313 uses the medical image data A to D stored in the memory 314 to generate the medical image data file X (step S37).

Specifically, for example, the medical image data A “without contrast agent” acquired on the current day is subtracted from the medical image data B “with contrast agent” acquired on the current day. Generate a subtraction image at . In addition, the medical image data C “without contrast agent” acquired in the past for the same patient is subtracted from the medical image data D “with contrast agent” acquired in the past for the same patient. Generate a subtraction image at . Then, the medical image data file X is generated by, for example, arranging the subtraction image of the current day and the subtraction image of the past in parallel. The processing circuit 313 stores the generated medical image data file X in the memory 314 . Further, the processing circuit 313 transmits the generated medical image data file X in response to a request from a user such as an interpreting doctor.

As described above, in the first embodiment, as shown in FIG. 5, medical image data necessary for diagnosis, for example, the , collects previously acquired medical data from an external storage device. Then, as soon as necessary medical image data are prepared, data processing is performed. Conventionally, for example, as shown in FIG. 6, after the first medical image data and the second medical image data are acquired, a display request from the user is waited, and the first medical image data required for the requested display is displayed. , medical image data other than the second medical image data. Further, after this acquisition, data processing is performed on the first and second medical image data and the acquired medical image data. Therefore, the user cannot confirm the desired display unless he/she waits for a predetermined time after inputting the display request. According to the medical data file generation device according to the first embodiment, without waiting for a display request from a user, medical data required for display is automatically collected, and data processing is performed on the collected medical data. do. Therefore, the medical data file generation device can complete the generation of the desired medical data file before the user inputs the display request.

Note that FIG. 3 illustrates an example in which the processing circuit 313 manages the medical image data stored in the remote database 61 by referring to the identification information stored in the local database 311 . However, the existence of medical image data stored in the remote database 61 need not be managed by the processing circuitry 313 .

For example, if the search in the local database 311 in step S33 fails to find the medical image data B, C, D, the processing circuit 313 needs to collect the medical image data B, C, D from the remote database 61. (Yes in step S34). Upon determining that medical image data B, C, and D need to be acquired from remote database 61 , processing circuitry 313 performs acquisition function 3133 . In the acquisition function 3133, the processing circuit 313 searches for medical image data B, C, and D from the remote database 61, for example, by referring to the supplementary information. In the example shown in FIG. 4, medical image data C and D are stored in the remote database 61 . The processing circuit 313 finds the medical image data C and D in the remote database 61, reads the found medical image data C and D, and stores them in the memory 314 (step S35).

Also, in FIG. 3, the case where the processing circuit 313 reads out the definition file 3142 as the amount of medical image data stored in the local database 311 increases has been described as an example. However, the timing at which the processing circuit 313 reads the definition file 3142 is not limited to this. The processing circuit 313 may read the definition file based on the order information transmitted from the medical image diagnostic apparatus 40 .

FIG. 7 is a flow chart showing another example of the operation of the processing circuit 313 of the server device 31 shown in FIG. 2 when generating a medical data file. 8 is a schematic diagram for explaining the operation shown in FIG. In the description of FIG. 8, as in the description of FIG. 4, it is assumed that the medical image diagnostic apparatus 40 generates medical image data A and then generates medical image data B for the same patient. 7 and 8, the order information includes, for example, imaging conditions including the presence or absence of a contrast agent, the purpose of examination, imaging parameters, and the like.

First, the server device 31 of the medical image management system 30 receives order information and patient information from the medical image diagnostic apparatus 40 (step S71). The processing circuit 313 of the server device 31 executes the determination function 3132 upon receiving the order information and patient information. In the determination function 3132, the processing circuit 313 determines whether or not the acquired medical data can be specified based on the received order information (step S72). The medical data to be acquired can be specified based on the order information, for example, the presence or absence of a contrast agent in the imaging conditions, and characteristic words for the purpose of examination, such as subtraction, calcium score, 3D, MPR, etc. is to be included.

If the medical data to be acquired based on the order information can be specified (Yes in step S72), the processing circuit 313 specifies the medical data to be acquired based on the order information. The processing circuit 313 reads out from the memory 314 the definition file 3142 listing the specified medical data as necessary medical data (step S73). In FIG. 8, the processing circuit 313 determines, based on the received order information, that the medical image data A and B, for example, will be acquired by imaging with the medical image diagnostic apparatus 40 . The processing circuit 313 reads from the memory 314 the definition file 3142 that lists the medical image data A and B as necessary medical data. The definition file 3142 read in step S73 defines, for example, medical data necessary to generate a medical image data file X for follow-up observation using subtraction images.

After reading out the definition file 3142, the processing circuit 313 refers to the definition file 3142 and determines that the medical image data A, B, C, and D are medical image data further necessary to generate the medical image data file X. to decide. The processing circuit 313 searches the local database 311 for the medical image data C and D other than the medical image data A and B acquired by imaging according to the order information among the medical image data A, B, C and D. (Step S74). Here, the medical image data C and D are managed by the remote database 61, and identification information is stored in the local database 311. FIG. That is, the local database 311 does not store the medical image data C and D, but stores the identification information of the medical image data C and D. FIG.

After searching the local database 311, processing circuitry 313 determines whether medical image data needs to be acquired (step S75). In FIG. 8, since the identification information of the medical image data C and D is stored in the local database 311, the processing circuit 313 determines that it is necessary to collect the medical image data C and D from the remote database 61 (step Yes in S75).

Upon determining that medical image data needs to be acquired, processing circuitry 313 performs acquisition function 3133 . In the acquisition function 3133 , the processing circuit 313 refers to the identification information stored in the local database 311 , reads the medical image data C and D from the remote database 61 , and stores the read medical image data C and D in the memory 314 . (Step S76).

After storing the medical image data C and D in the memory 314 , the processing circuit 313 executes the generating function 3134 . In the generation function 3134, the processing circuit 313 performs data processing on the medical image data C and D stored in the memory 314 (step S77). Specifically, for example, the previously acquired medical image data C "without contrast agent" for the same patient is subtracted from the previously acquired medical image data D "with contrast agent" for the same patient ( subtraction) to generate a subtraction image in the past.

After executing the data processing for the medical image data stored in the memory 314, the processing circuit 313 waits for execution of the generation function 3134 until the medical image data A and B obtained by imaging according to the order information are received. (step S78). Further, in step S75, if there is no need to collect medical image data from the remote database 61, that is, if the medical image data C and D are stored in the local database 311 (No in step S75), the processing circuit 313 The process is moved to step S78.

The medical image diagnostic apparatus 40 generates medical image data A by imaging without a contrast medium according to the received order information. The medical image diagnostic apparatus 40 transmits the generated medical image data A to the medical image management system 30 . When receiving the medical image data A, the processing circuit 313 causes the control function 3131 to store the received medical image data A in the memory 314 .

When medical image data A is generated by imaging without a contrast agent by the medical image diagnostic apparatus 40, a contrast agent is administered to the patient. The medical image diagnostic apparatus 40 takes an image of the patient to whom the contrast medium has been administered, and generates medical image data B. FIG. The medical image diagnostic apparatus 40 transmits the generated medical image data B to the medical image management system 30 . When receiving the medical image data B, the processing circuit 313 causes the control function 3131 to store the received medical image data B in the memory 314 .

When the medical image data B is stored in the memory 314 , that is, when all the medical image data defined in the definition file 3142 are ready, the processing circuitry 313 executes the generation function 3134 . In the generating function 3134 , the processing circuit 313 generates the medical image data file X using the medical image data A to D stored in the memory 314 . The processing circuit 313 transmits the generated medical image data file X in response to a request from a user such as an interpreting doctor.

As described above, the medical data file generation apparatus according to the first embodiment converts medical image data other than medical image data acquired based on received order information into order information, as shown in FIG. Based on this, data is collected from the remote database 61 . That is, the medical image data stored in the remote database 61 is collected before the medical image diagnostic apparatus 40 starts imaging and/or in the background when the medical image diagnostic apparatus 40 generates the first medical image data. . Data processing of the medical image data collected from the remote database 61 is performed before the first and second medical image data are acquired. In other words, data processing for medical image data other than medical image data acquired based on order information is autonomously performed during imaging based on order information. This makes it possible to reduce the data processing amount after acquiring the first and second medical image data. That is, it becomes possible to advance the diagnostic possible time.

In FIG. 7, the case where the medical image data generated by the medical image diagnostic apparatus 40 is grasped based on the received order information has been described as an example. However, it is not limited to this. The processing circuit 313 may also refer to the imaging plan set in the radiology department information system 20 to grasp the generated medical image data. At this time, the imaging plan is transmitted from the server device 21 of the radiology department information system 20 to the server device 31 of the medical image management system 30 via the medical image diagnostic apparatus 40 . The imaging plan may be transmitted from the server device 21 of the radiology department information system 20 to the server device 31 of the medical image management system 30 .

In addition, FIG. 7 describes an example in which the processing circuit 313 reads the definition file 3142 based on the order information. However, the timing at which the processing circuit 313 reads the definition file 3142 is not limited to this. The processing circuit 313 may read the definition file at a preset cycle.

Specifically, for example, the processing circuitry 313 executes the determination function 3132 at a preset cycle. In decision function 3132 , processing circuit 313 reads definition file 3142 from memory 314 . Processing circuitry 313 determines whether or not medical data defined in definition file 3142 is stored in local database 311 . If all of the medical data defined in definition file 3142 is stored in local database 311, processing circuitry 313 generates a medical data file based on the stored medical data.

If at least some of the medical data defined in definition file 3142 is not stored in local database 311 , processing circuitry 313 collects the missing medical data from remote database 61 . When all the medical data defined in the definition file 3142 are obtained by collection from the remote database 61, the processing circuitry 313 generates a medical data file based on the stored medical data.

Even after collecting the medical data from the remote database 61, if there is missing medical data with respect to the medical data defined in the definition file 3142, the processing circuit 313 receives the missing medical data. Execution of the generation function 3134 is waited until .

Also, in FIG. 3, the case where the medical image data B is generated after the medical image data A is generated by the medical image diagnostic apparatus 40 has been described as an example. However, medical image data B is not necessarily generated after medical image data A is generated.

FIG. 10 is a flow chart showing another example of the operation of the processing circuit 313 of the server device 31 shown in FIG. 2 when generating a medical data file. In FIG. 10, steps S31 to S36 are the same as steps S31 to S36 shown in FIG.

The processing circuit 313 determines whether or not the standby time after acquiring the medical image data C and D has reached a preset time (step S101). If the preset time is reached (Yes in step S101), the processing circuitry 313 executes the collection function 3133. FIG. In the acquisition function 3133, the processing circuit 313 acquires the remaining unacquired medical image data among the medical image data defined in the definition file as the second medical image data following the first medical image data. A prompting display is generated (step S102).

Specifically, for example, the processing circuit 313 stores the medical image data A stored in step S31 and the medical image data C and D acquired in step S35 among the medical image data A to D defined in the definition file 3142. Other medical image data B is set as medical image data to be acquired next. The processing circuit 313 generates a display prompting acquisition of the medical image data B, and transmits this display data to the hospital information system 10, the radiology department information system 20, and the medical image diagnostic apparatus 40, for example.

When the server device 11 of the hospital information system 10 receives the display data urging acquisition of the medical image data B from the medical image management system 30, for example, the server 11 of the hospital information system 10 displays the urging acquisition of the medical image data B in the electronic medical record. Write in information. This assists the attending physician in issuing the order. Further, when the server device 21 of the radiology department information system 20 receives the display data prompting the acquisition of the medical image data B from the medical image management system 30, for example, the medical A prompt to obtain image data B is displayed. This will assist radiology staff in issuing orders. Further, when the medical image diagnostic apparatus 40 receives the display data urging acquisition of the medical image data B from the medical image management system 30, the urging acquisition of the medical image data B is displayed on the display, for example. This helps the staff who operate the medical image diagnostic apparatus 40 to perform examinations. In this way, it is possible to prevent forgetting to obtain the necessary medical image data by displaying to the doctor, etc., a prompt to obtain medical image data that has not yet been obtained among the medical image data defined in the definition file. becomes.

If the preset time has not been reached (No in step S101), the processing circuit 313 determines whether or not the remaining medical image data, that is, the medical image data B has been received (step S103). When the processing circuit 313 receives the medical image data B (Yes in step S<b>103 ), the processing circuit 313 stores the received medical image data B in the memory 314 . Once medical image data B is stored in memory 314 , processing circuit 313 performs generate function 3134 . In the generation function 3134, the processing circuit 313 uses the medical image data A to D stored in the memory 314 to generate the medical image data file X (step S104). If the medical image data B is not received (No in step S103), the processing circuitry 313 causes the process to proceed to step S101.

The processing circuit 51 is a processor that functions as the core of the communication terminal 50 . The processing circuit 51 implements a function corresponding to the program by executing the program stored in the memory 52 or the like.

The memory 52 is, for example, a storage device such as a ROM, RAM, HDD, SSD, or integrated circuit that stores various information. Also, the memory 52 may be a drive device or the like that reads and writes various information from/to a portable storage medium such as a CD-ROM drive, a DVD drive, or a flash memory.

The memory 52 stores a medical data file generation program and the like according to this embodiment.

Alternatively, for example, it may be stored in a non-transitory storage medium and distributed, read from the non-transitory storage medium and installed in the memory 52 .

The memory 52 stores definition files 521 . The definition file 521 exists, for example, for each type of diagnosis and each type of medical data file to be generated. The definition file 521 may be pre-stored in the memory 52, for example. Alternatively, for example, it may be stored in a non-transitory storage medium and distributed, read from the non-transitory storage medium and installed in the memory 52 .

The input interface 53 receives various input operations from the user, converts the received input operations into electrical signals, and outputs the electrical signals to the processing circuit 51 .

The collecting function 512 is a function for collecting medical data from the remote database 61 constructed in the storage server 60, and is an example of collecting means. Specifically, for example, in the collection function 512 , when at least a part of the medical data defined in the definition file 521 does not exist in the local database 311 , the processing circuit 313 collects the non-existing medical data from the remote database 61 . collect.

The generating function 513 is a function of generating a medical data file from acquired medical data, and is an example of generating means. Specifically, for example, in the generating function 513, the processing circuitry 51 generates a medical data file based on the necessary medical data if the local database 311 has the necessary medical data. That is, the processing circuit 51 generates a medical data file from the medical data acquired from the local database 311, the medical data collected from the remote database 61, and the newly acquired medical data.

Next, an example of the operation of the communication terminal 50 as a medical data file generation device configured as described above will be described according to the processing procedure of the processing circuit 51. FIG.

In an acquisition function 512 , the processing circuit 51 acquires medical image data not present in the local database 311 from the remote database 61 .

Processing circuitry 51 executes generation function 513 when all medical data defined in definition file 521 is stored in local database 311 . In the generating function 513, the processing circuitry 51 uses the medical image data stored in the local database 311 to generate a medical image data file.

As described above, in the second embodiment, medical image data required for diagnosis is collected from the external storage device during the imaging of the second medical image that is performed after the imaging of the first medical image. Then, as soon as necessary medical image data are prepared, data processing is performed. As a result, according to the medical data file generation device according to the second embodiment, without waiting for a display request from the user, the medical data required for display is automatically collected, and the data about the collected medical data is collected.
