For example, the processing circuit 313 functions as the control function 3131, the judgment function 3132, the collection function 3133, and the generation function 3134 by executing the medical data file generation program. In the present embodiment, a case where the control function 3131, the judgment 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 control circuit 3131, a judgment function 3132, a collection function 3133, and a generation function 3134 may be realized by configuring a processing circuit by combining a plurality of independent processors and executing a program by each processor.

The control function 3131 is a function of controlling the entire processing of the server device 31 as the local database 311. Specifically, for example, the processing circuit 313 in the control function 3131 stores the medical image data transmitted from the medical image diagnostic apparatus 40 in the memory 314. Further, the processing circuit 313 transfers the substance to the storage server 60 while storing the identification information in the memory 314 for some of the medical image data stored in the memory 314, for example.

The processing circuit 313 determines whether or not the medical data defined in the read definition file 3142 is available in the local database 311.

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

The generation function 3134 is a function of generating a medical data file from the acquired medical data, and is an example of a generation unit. Specifically, for example, in the generation function 3134, the processing circuit 313 generates a medical data file based on the medical data when necessary medical data is available in the local database 311. That is, the processing circuit 313 generates a medical data file from the medical data acquired by 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 the 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. 3 is a flowchart showing an example of operation when the processing circuit 313 of the server device 31 shown in FIG. 2 generates a medical data file. 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 the medical image data A and then the medical image data B for the same patient. The incidental 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 the medical image data A generated by the medical image diagnostic device 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).

The processing circuit 313 executes the determination function 3132 when the number of medical image data stored in the memory 314 increases, that is, when the medical image data A is stored in the memory 314. In the determination function 3132, the processing circuit 313 reads out the definition file 3142, which is cited as the medical data that requires the medical image data A, 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 a subtraction image. In FIG. 4, “X” represents the medical image data file X for follow-up observation using the subtraction image. In FIG. 4, the medical data required to create the medical image data file X is defined as “A”, “B”, “C”, and “D”.

In FIG. 4, “A” represents, for example, medical image data acquired on the current day based on the order information of “without contrast agent”. The incidental information of the medical image data A includes the examination date, the patient ID, the contrast agent information of “no contrast agent”, and the like. “B” represents medical image data of the same patient acquired on the current day, for example, based on the order information of “with contrast agent”. The incidental information of the medical image data B includes the examination date, the patient ID, the contrast agent information “with contrast agent”, and the like. “C” represents medical image data of the same patient acquired in the past based on the order information of “no contrast agent”. The incidental information of the medical image data C includes the examination date, the patient ID, the contrast agent information of "no contrast agent", and the like. “D” represents medical image data of the same patient acquired in the past based on the order information of “with contrast medium”. The incidental information of the medical image data D includes the examination date, the patient ID, the contrast agent information “with contrast agent”, and the like.

When the processing circuit 313 reads 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 for generating the medical image data file X. .. The processing circuit 313 searches the local database 311 for medical image data B, C, and D (step S33). In FIG. 4, medical image data B is generated by the medical image diagnostic apparatus 40. The medical image data C and D are managed by the remote database 61, and the local database 311 stores identification information. That is, the local database 311 does not store the medical image data B, C, D, but stores the identification information of the medical image data C, D. The identification information includes information that can identify medical image data, address information of a database that stores medical image data, and the like.

When the search of the local database 311 is completed, the processing circuit 313 determines whether it is necessary to collect medical image data (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).

When determining that it is necessary to collect the medical image data, the processing circuit 313 executes the collecting function 3133. In the collecting function 3133, the processing circuit 313 refers to the identification information stored in the local database 311, and acquires the address of the remote database 61 storing the medical image data C and D. The processing circuit 313 accesses the remote database 61 using the acquired 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 for execution of the generation function 3134 until the remaining medical image data, that is, the medical image data B is received (step S36). Further, when it is not necessary to collect the medical image data from the remote database 61 in step S34, that is, when the medical image data C and D are stored in the local database 311 (No in step S34), the processing circuit 313: The process proceeds to step S36.

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

Upon 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 prepared, the processing circuit 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 of “without contrast agent” acquired on the current day is subtracted (subtracted) from the medical image data B of “with contrast agent” acquired on the current day to obtain the current date. Generate a subtraction image in. Further, medical image data C of “without contrast agent” of the same patient acquired in the past is subtracted (subtracted) from medical image data D of “with contrast agent” of the same patient acquired in the past, Generate a subtraction image in. Then, the subtraction image of the current date and the subtraction image of the past are arranged, for example, in parallel to generate the medical image data file X. The processing circuit 313 stores the generated medical image data file X in the memory 314. In addition, the processing circuit 313 transmits the generated medical image data file X in response to a request from a user such as an image interpretation doctor.

As described above, in the first embodiment, as shown in FIG. 5, during the capturing of the second medical image performed after capturing the first medical image, the medical image data necessary for diagnosis, for example, , Collect medical data acquired in the past from an external storage device. Then, data processing is carried out as soon as necessary medical image data are prepared. 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 for, and the first required for the requested display. , Medical image data other than the second medical image data was collected. In addition, after this collection, data processing is performed on the first and second medical image data and the collected medical image data. Therefore, the user cannot confirm the desired display without waiting for a predetermined time after inputting the display request. The medical data file generating apparatus according to the first embodiment automatically collects medical data required for display without waiting for a display request from the user, and executes data processing on the collected medical data. To do. Therefore, the medical data file generation device can complete generation of a desired medical data file before the user inputs a display request.

Note that, in FIG. 3, the case where the processing circuit 313 manages the medical image data stored in the remote database 61 with reference to the identification information stored in the local database 311 has been described as an example. However, the presence of the medical image data stored in the remote database 61 does not have to be managed by the processing circuit 313.

For example, when the medical image data B, C, D cannot be found by the search in the local database 311 in step S33, the processing circuit 313 needs to collect the medical image data B, C, D from the remote database 61. (Yes in step S34). When it is determined that the medical image data B, C, and D need to be collected from the remote database 61, the processing circuit 313 executes the collection function 3133. In the collection function 3133, the processing circuit 313 refers to the supplementary information, for example, and retrieves the medical image data B, C, D from the remote database 61. In the example shown in FIG. 4, the remote database 61 stores medical image data C and D. 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).

Further, in FIG. 3, the case where the processing circuit 313 reads the definition file 3142 according to the increase in the medical image data stored in the local database 311 has been described as an example. However, the timing when 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 flowchart showing another example of the operation when the processing circuit 313 of the server device 31 shown in FIG. 2 generates a medical data file. Further, FIG. 8 is a schematic diagram for explaining the operation shown in FIG. 7. In the description of FIG. 8 as well, similar to the description of FIG. 4, it is assumed that the medical image diagnostic apparatus 40 creates the medical image data A and then creates the medical image data B for the same patient. Further, in the description of FIGS. 7 and 8, it is assumed that the order information includes, for example, imaging conditions including the presence/absence of a contrast agent, examination purpose, imaging parameters and the like.

First, the server device 31 of the medical image management system 30 receives the order information and the patient information from the medical image diagnostic device 40 (step S71). Upon receiving the order information and the patient information, the processing circuit 313 of the server device 31 executes the judgment function 3132. In the determination function 3132, the processing circuit 313 determines whether 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 imaging conditions, the presence or absence of a contrast agent, and characteristic words for inspection purposes, such as subtraction, calcium score, 3D, MPR, etc. Is included.

When the medical data acquired based on the order information can be specified (Yes in step S72), the processing circuit 313 specifies the acquired medical data based on the order information. The processing circuit 313 reads from the memory 314 the definition file 3142, which is cited as the medical data that requires the specified medical data (step S73). In FIG. 8, the processing circuit 313 determines that, for example, the medical image data A and B is acquired by the imaging of the medical image diagnostic apparatus 40 based on the received order information. The processing circuit 313 reads from the memory 314 a definition file 3142, which is listed as medical data that requires the medical image data A and B. 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 a subtraction image.

When the processing circuit 313 reads out the definition file 3142, the processing circuit 313 refers to the definition file 3142 and finds 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 medical image data A, B, C, D for medical image data C, D other than the medical image data A, B acquired by imaging according to the order information in the local database 311. (Step S74). Here, the medical image data C and D are managed by the remote database 61, and the local database 311 stores identification information. 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.

When the search of the local database 311 is completed, the processing circuit 313 determines whether it is necessary to collect medical image data (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 of S75).

When determining that it is necessary to collect the medical image data, the processing circuit 313 executes the collecting function 3133. In the collecting 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).

When the processing circuit 313 stores the medical image data C and D in the memory 314, the processing circuit 313 executes the generation 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, from the medical image data D of “with contrast agent” of the same patient acquired in the past, the medical image data C of “without contrast agent” of the same patient acquired in the past is subtracted ( Subtraction) to generate a subtraction image in the past.

When the data processing is performed on the medical image data stored in the memory 314, the processing circuit 313 waits for execution of the generation function 3134 until it receives the medical image data A and B acquired by imaging according to the order information. Yes (step S78). Further, in step S75, when it is not necessary to collect the medical image data from the remote database 61, that is, when the medical image data C and D are stored in the local database 311, (No in step S75), the processing circuit 313 The process proceeds to step S78.

The medical image diagnostic apparatus 40 generates medical image data A by imaging without a contrast agent 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. Upon 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 the medical image data A is generated by imaging without the contrast agent by the medical image diagnostic apparatus 40, the contrast agent is administered to the patient. The medical image diagnostic apparatus 40 captures an image of a patient to which a contrast agent has been administered, and generates medical image data B. The medical image diagnostic apparatus 40 transmits the generated medical image data B to the medical image management system 30. Upon 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 prepared, the processing circuit 313 executes the generation function 3134. In the generation 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 image interpretation doctor.

As described above, the medical data file generation apparatus according to the first embodiment uses the medical image data other than the medical image data acquired based on the received order information as the order information, as shown in FIG. Based on 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 in which the medical image diagnostic apparatus 40 generates the first medical image data. .. The data processing on the medical image data collected from the remote database 61 is performed before the first and second medical image data are acquired. That is, the data processing of the medical image data other than the medical image data acquired based on the order information is autonomously performed during the imaging based on the order information. This makes it possible to reduce the data processing amount after the first and second medical image data are acquired. That is, the diagnosable time can be advanced.

In addition, 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 grasp the medical image data generated by also referring to the imaging plan set in the radiation department information system 20. At this time, the imaging plan is transmitted from the server apparatus 21 of the radiation department information system 20 to the server apparatus 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 radiation department information system 20 to the server device 31 of the medical image management system 30.

Further, in FIG. 7, the case where the processing circuit 313 reads the definition file 3142 based on the order information has been described as an example. However, the timing when 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 circuit 313 executes the determination function 3132 at a preset cycle. In the judgment function 3132, the processing circuit 313 reads the definition file 3142 from the memory 314. The processing circuit 313 determines whether the medical data defined in the definition file 3142 is stored in the local database 311. When all of the medical data defined by the definition file 3142 is stored in the local database 311, the processing circuit 313 generates a medical data file based on the stored medical data.

When at least a part of the medical data defined in the definition file 3142 is not stored in the local database 311, the processing circuit 313 collects the missing medical data from the remote database 61. When all the medical data defined in the definition file 3142 is acquired by the collection from the remote database 61, the processing circuit 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 for the medical data defined in the definition file 3142, the processing circuit 313 receives the missing medical data. It waits until the generation function 3134 is executed.

In addition, 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, the medical image data B is not always generated after the medical image data A is generated.

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

The processing circuit 313 determines whether the waiting time after acquiring the medical image data C and D has reached a preset time (step S101). When the preset time has been reached (Yes in step S101), the processing circuit 313 executes the collection function 3133. In the collecting function 3133, the processing circuit 313 is configured to acquire, as the second medical image data subsequent to the first medical image data, the remaining unacquired medical image data among the medical image data defined in the definition file. A prompting display is generated (step S102).

Specifically, for example, the processing circuit 313, among the medical image data A to D defined in the definition file 3142, the medical image data A stored in step S31 and the medical image data C and D collected in step S35. The medical image data B other than the above is set as the 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, for example, the hospital information system 10, the radiation department information system 20, and the medical image diagnostic apparatus 40.

When the server device 11 of the hospital information system 10 receives the display data urging the acquisition of the medical image data B from the medical image management system 30, for example, the server device 11 notifies the electronic medical chart that the acquisition of the medical image data B is requested. Write in the information. This helps the clinician in issuing the order. Further, when the server device 21 of the radiation 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 screen is displayed on the input screen when the order information is input. A message prompting acquisition of the image data B is displayed. This will help staff in the Radiology department to issue orders. Further, when the medical image diagnostic apparatus 40 receives the display data to the effect that acquisition of the medical image data B is requested from the medical image management system 30, the medical image diagnosis apparatus 40 displays, for example, on the display, an instruction to acquire the medical image data B. This helps the staff who operates the medical image diagnostic apparatus 40 when performing the examination. In this way, it is possible to prevent forgetting to acquire the necessary medical image data by displaying to the doctor, etc., a message prompting the acquisition of medical image data that has not been acquired among the medical image data defined in the definition file. Becomes

When the preset time has not been reached (No in step S101), the processing circuit 313 determines whether the remaining medical image data, that is, the medical image data B has been received (step S103). Upon receiving the medical image data B (Yes in step S103), the processing circuit 313 stores the received medical image data B in the memory 314. When the medical image data B is stored in the memory 314, the processing circuit 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 S104). When the medical image data B is not received (No in step S103), the processing circuit 313 shifts the processing to step S101.

Specifically, for example, in the collecting function 512, the processing circuit 313, if at least a part of the medical data defined in the definition file 521 does not exist in the local database 311, the non-existing medical data is extracted from the remote database 61. collect.

The generation function 513 is a function of generating a medical data file from the acquired medical data, and is an example of a generation unit. Specifically, for example, in the generation function 513, the processing circuit 51 generates a medical data file based on these medical data when necessary medical data is available in the local database 311. That is, the processing circuit 51 creates a medical data file from the medical data acquired by the local database 311, the medical data collected by the remote database 61, and the newly acquired medical data.
