Description

  The present invention relates to a maintenance technique for a medical apparatus such as an X-ray CT apparatus, an MRI apparatus, an ultrasonic diagnostic apparatus, or an X-ray diagnostic apparatus.

  Conventionally, remote maintenance has been performed on medical apparatuses such as an X-ray CT apparatus, an MRI apparatus, or an X-ray diagnostic apparatus (for example, Patent Document 1). The maintenance here includes upgrading various functions of the medical device, changing various parameters, and the like.

  When performing remote maintenance on a medical device, in order to avoid inconvenience caused by using the medical device during remote maintenance, conventionally, the date and time required for remote maintenance are set in advance. It was necessary to decide and reserve the use of the medical device to be maintained. During remote maintenance, the medical device is displayed to indicate that remote maintenance is being performed, or the operation of the medical device is restricted so that the medical device is not used.

JP 2002-306451 A

  As described above, conventionally, all functions of the medical device are stopped and remote maintenance is performed. In other words, all functions that are not related to the maintenance target function are stopped and remote maintenance is performed.

  However, since all the functions that are not related to the function that is the object of maintenance have also been stopped, even if the function that has nothing to do with the function that you want to use is maintained, the function that you want to use is executed. There was a problem that could not be done. For example, when you want to execute a certain function urgently, even if you are maintaining a function that has nothing to do with the function that was used urgently, all the functions are stopped and maintenance is performed. The function you want to use could not be performed. In this way, during remote maintenance, all functions that are not related to the maintenance target function are stopped and the medical apparatus cannot be operated at all, so the operation time of the medical apparatus is shortened. There was a problem.

  For example, the X-ray CT apparatus has a patient registration function for registering a patient in the apparatus, a function for setting imaging conditions in the apparatus, an imaging function, a log acquisition function for acquiring a log indicating the history of operation of the apparatus, and the like. Various functions can be performed. For example, when maintaining the log acquisition function, all functions of the X-ray CT apparatus have been stopped in the past, so other functions such as a patient registration function and an imaging function are executed during the maintenance. I could not. The log acquisition function is not related to other functions such as the patient registration function and imaging function, and maintenance of the log acquisition function affects the execution of other functions such as the patient registration function and imaging function. Even if there is no, all other functions such as the patient registration function and the imaging function were stopped during the maintenance of the log acquisition function. As described above, during the maintenance, all the functions that are not related to the maintenance target function (here, the log acquisition function) are also stopped, and thus the X-ray CT apparatus cannot be operated at all. The operating time of the X-ray CT apparatus has been shortened.

[First Embodiment]
The configuration of the medical system and medical device according to the first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a schematic configuration of a medical system according to the first embodiment of the present invention.

  The medical system 1 includes a medical institution 2 and a remote maintenance center 4. The medical institution 2 is provided with a medical device 3 such as an X-ray CT apparatus, an MRI apparatus, an ultrasonic diagnostic apparatus, or an X-ray diagnostic apparatus. The remote maintenance center 4 is provided with a remote maintenance device 5 for maintaining the medical device 3 remotely. Here, as an example, a case where the medical apparatus 3 is an X-ray CT apparatus will be described.

  The remote maintenance device 5 of the remote maintenance center 4 includes a maintenance terminal 51. The maintenance terminal 51 includes a display device and an input device. The maintenance terminal 51 is connected to the medical device 3 via a network, requests the medical device 3 to perform maintenance, and performs each function executed by the medical device 3. Used for maintenance. The maintenance execution request given by the maintenance terminal 51 is transmitted to the medical apparatus 3 via the network. Maintenance of the medical device 3 corresponds to acquisition of a service log of the medical device 3, upgrade of each function (software) of the medical device 3, change of various parameters, and the like. The maintenance terminal 51 transmits a request for performing such maintenance to the medical device 3 via the network, obtains a service log of the medical device 3 remotely, and upgrades each function (software) of the medical device 3 remotely. Implement or change various parameters remotely.

  The medical device 3 includes an operation terminal 31, a processing request receiving unit 32, an operation status confirmation unit 33, a maintenance availability determination unit 34, a related function list table storage unit 35, and a request processing unit 36.

  The processing request receiving unit 32 receives a maintenance execution request transmitted from the maintenance terminal 51 installed in the remote maintenance center 4.

  The related function list table storage unit 35 stores a related function list table indicating the operation of the medical device 3 and the functions executed in the operation. This related function list table is created in advance and stored in the related function list table storage unit 35.

  This related function list table is a criterion for determining whether or not the maintenance requested by the maintenance terminal 51 can be performed during the operation of the medical device 3 at the time when the maintenance is requested. That is, the related function list table determines whether or not the maintenance for the function (maintenance target function) for performing remote maintenance at the maintenance terminal 51 can be performed during the operation of the medical device 3 when the maintenance is requested. It will be a standard.

  When the function of performing remote maintenance at the maintenance terminal 51 (maintenance target function) corresponds to a function executed in a certain operation, it is determined that maintenance for the maintenance target function cannot be performed. On the other hand, when the function of performing remote maintenance (maintenance target function) at the maintenance terminal 51 does not correspond to the function executed in a certain operation, it is determined that the maintenance for the maintenance target function can be performed.

  An example of the related function list table is shown in FIG. FIG. 2 is a table showing an example of the related function list table. When the medical apparatus 3 is an X-ray CT apparatus, operations performed by the medical apparatus 3 include, for example, (1) normal imaging, (2) contrast imaging, (3) contrast imaging film interlocking, (4) imaging condition setting, (5) File operation, (6) Film output, (7) 3D processing (image processing), (8) Reconfiguration Retry, and the like are applicable. The operation shown in FIG. 2 is an example of the operation performed by the medical device 3 as the X-ray CT apparatus, and the medical device 3 also executes an operation other than the operation shown in FIG.

  In the related function list table, functions executed in each operation are shown. Examples of functions executed by the medical device 3 include (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, (E) film output function, (F) This includes a file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function. In the related function list table, the function scheduled to be executed is a function that is always executed in the operation. An unused function is a function that is not executed in the operation. The function that is undetermined may or may not be executed in the operation. For example, the function may be executed in accordance with an instruction from the operator. In other words, the function that has not been determined is a function that is selectively executed.

  In other words, the related function list table indicates functions (processes) that can be maintained in each operation. That is, a function that is scheduled to be executed in an operation is a function that is always executed in the operation, and thus cannot be maintained during the operation. For this reason, when the function (maintenance target function) for performing remote maintenance on the maintenance terminal 51 corresponds to a function scheduled to be executed in a certain operation, the maintenance target function cannot be maintained. To be judged.

  On the other hand, a function that is not used in an operation is a function that is not executed in the operation, and is a function that can be maintained during the operation. Therefore, when the function for performing remote maintenance (maintenance target function) in the maintenance terminal 51 corresponds to a function that is not scheduled to be executed in a certain operation, it is determined that maintenance for the maintenance target function can be performed. Is done.

  A function whose execution is undetermined in a certain operation is a function that is selectively executed. That is, an undetermined function is a function in which whether or not maintenance is possible is determined according to an instruction from the operator because it may or may not be executed in the operation. Therefore, when the function of performing remote maintenance (maintenance target function) in the maintenance terminal 51 corresponds to a function that has not been executed in a certain operation, whether or not maintenance is possible is determined according to an instruction from the operator.

  Here, functions executed in (1) normal imaging, (3) contrast imaging film interlocking, and (7) 3D processing (image processing), and a processing flow in each operation will be described.

  First, (1) functions executed in normal photographing and a flow of processing will be described with reference to FIGS. FIG. 3 is a flowchart showing the flow of processing in normal shooting.

  (1) In normal imaging, as shown in FIG. 2, (A) patient registration function, (B) imaging condition setting function, and (C) imaging function are scheduled to be executed, and (E) film output function Is undecided. Accordingly, the medical device 3 executes (A) a patient registration function, (B) an imaging condition setting function, and (C) an imaging function. The medical device 3 may execute (E) a film output function.

  (A) The patient registration function is a function for registering information for identifying a patient such as a patient ID and a patient name in the medical device 3 using the operation terminal 31, for example. (B) The imaging condition setting function is a function for setting imaging conditions (imaging parameters) by the medical device 3 using the operation terminal 31, for example. When the medical apparatus 3 is an X-ray CT apparatus, the imaging conditions include a helical scan condition in addition to the voltage value and current value of the X-ray tube. (C) The imaging function is a function for performing imaging by actually operating the medical apparatus 3 and acquiring medical image data. When the medical apparatus 3 is an X-ray CT apparatus, the imaging function is a function that causes the medical apparatus 3 to perform imaging such as helical scanning. The (E) film output function is a function for printing a medical image obtained by photographing a patient with the medical device 3 on a film. (1) In normal shooting, the (E) film output function is not necessarily executed, and is a function executed when an instruction is given from an operator, for example.

  In (1) normal imaging, as shown in FIG. 2, (D) contrast imaging function, (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition The function is unused. Therefore, the medical device 3 does not execute (D) contrast imaging function, (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function.

  As described above, in (1) normal imaging, not all functions of the medical device 3 are executed, but (1) functions related to normal imaging are executed.

  Therefore, since the (A) patient registration function, (B) imaging condition setting function, and (C) imaging function are executed in (1) normal imaging, the operation of the medical device 3 is (1) normal imaging, Remote maintenance cannot be performed from the maintenance terminal 51 for the (A) patient registration function, (B) imaging condition setting function, and (C) imaging function.

  On the other hand, since (D) contrast imaging function, (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function are not executed in (1) normal imaging, the medical device 3 When the operation of (1) normal imaging, (D) contrast imaging function, (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function are maintained. Remote maintenance can be performed from the terminal 51.

  In addition, since the (E) film output function may or may not be executed in (1) normal imaging, the operation of the medical device 3 is (1) normal imaging according to an operator's instruction. Whether maintenance is possible is determined.

  As shown in the flowchart of FIG. 3, after registration of the patient at the operation terminal 31 (step S01), the imaging conditions are set at the operation terminal 31 (step S02). Shooting is executed (step S03). When the medical apparatus 3 is an X-ray CT apparatus, for example, the medical apparatus 3 acquires a tomographic image data of a patient by executing a helical scan. Further, when an instruction for film output is given by the operator, the medical apparatus 3 prints a medical image acquired by photographing on the film (step S04). Thereafter, when another patient is photographed, patient registration is newly performed (step S01).

  Next, (3) functions executed in contrast imaging film linkage and the flow of processing will be described with reference to FIGS. FIG. 4 is a flowchart showing the flow of processing in conjunction with contrast imaging film.

  (3) In contrast imaging, as shown in FIG. 2, (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, and (E) film output function Is scheduled to run. Accordingly, the medical device 3 executes (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, and (E) film output function.

  (D) The contrast imaging function acquires a medical image by performing imaging (prep scan) in a state in which a contrast medium is injected into a patient, and changes a CT value in a region of interest (ROI) set in the medical image. Based on this, it is a function for measuring the timing of starting helical scan (main scan). For example, when the CT value in the region of interest (ROI) becomes greater than or equal to a preset threshold value, the medical device 3 starts a helical scan (main scan).

  In addition, in (3) contrast imaging film interlocking, as shown in FIG. 2, (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function are unused. It has become. Therefore, the medical device 3 does not execute the (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function.

  As described above, (3) not all functions of the medical device 3 are executed in contrast imaging film interlocking, but (3) functions related to contrast imaging film interlocking are executed.

  Accordingly, (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging, and (E) film output function are executed in (3) contrast imaging film interlocking. When the operation of the medical device 3 is (3) linked with contrast imaging film, (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast function, and (E) film output For functions, remote maintenance cannot be performed from the maintenance terminal 51.

  On the other hand, since the (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function are not executed in conjunction with (3) contrast imaging film, the operation of the medical device 3 is (3 ) In the case of contrast imaging film linkage, remote maintenance can be performed from the maintenance terminal 51 for (F) file operation function, (G) 3D processing (image processing) function, and (H) service log acquisition function. .

  Then, as shown in the flowchart of FIG. 4, after the patient is registered at the operation terminal 31 (step S10), the imaging conditions are set at the operation terminal 31 (step S11), and then the patient is contrasted. The medical device 3 injects the agent, and executes the prep scan to measure the timing of starting the main scan (step S12). Then, when the timing for starting the main scan is given, the medical apparatus 3 performs imaging by executing a helical scan, and acquires tomographic image data of the patient (step S13). Note that the shooting conditions can be changed even during shooting. Then, the medical device 3 prints a medical image acquired by photographing on a film (step S14). Thereafter, when another patient is registered, patient registration is newly performed (step S10).

  Next, (7) functions executed in 3D processing (image processing) and processing flow will be described with reference to FIGS. FIG. 5 is a flowchart showing the flow of processing in 3D processing (image processing).

  (7) In 3D processing (image processing), as shown in FIG. 2, (F) file operation function and (G) 3D processing (image processing) function are scheduled to be executed, and (E) film output The function is undecided. Therefore, the medical device 3 executes (F) file operation function and (G) 3D processing (image processing) function. The medical device 3 may execute (E) a film output function.

  (F) The file operation function is a function for designating volume data to be subjected to image processing using the operation terminal 31, for example. (G) The 3D processing (image processing) function performs display image data such as three-dimensional image data and MPR image data by performing image processing such as volume rendering and MPR processing on the specified volume data. Generate. (G) An image based on the image data generated by the 3D processing (image processing) function is displayed on the display device of the operation terminal 31.

  In (7) 3D processing (image processing), as shown in FIG. 2, (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, and (H) The service log acquisition function is not used. Therefore, the medical apparatus 3 does not execute (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, and (H) service log acquisition function.

  As described above, in (7) 3D processing (image processing), not all functions of the medical device 3 are executed, but (7) functions related to 3D processing (image processing) are executed. become.

  Therefore, since the (F) file operation function and the (G) 3D processing (image processing) function are executed in (7) 3D processing (image processing), the operation of the medical device 3 is (7) 3D processing (image processing). In the case of (processing), remote maintenance cannot be performed from the maintenance terminal 51 for (F) file operation function and (G) 3D processing (image processing) function.

  On the other hand, (A) Patient registration function, (B) Imaging condition setting function, (C) Imaging function, (D) Contrast imaging function, and (H) Service log acquisition function are (7) 3D processing (image processing) When the operation of the medical device 3 is (7) 3D processing (image processing), (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, And (H) Remote maintenance can be performed from the maintenance terminal 51 for the service log acquisition function.

  In addition, since the (E) film output function may or may not be executed in (7) 3D processing (image processing), the operation of the medical device 3 is (7) 3D processing (image processing). In this case, whether or not maintenance is possible is determined according to an instruction from the operator.

  Then, as shown in the flowchart of FIG. 5, after volume data to be subjected to image processing is designated on the operation terminal 31 (step S20), the medical apparatus 3 performs image processing such as volume rendering on the volume data. To generate image data for display such as three-dimensional image data (step S21). Further, when an instruction for film output is given by the operator, the medical apparatus 3 prints the generated image on the film (step S22).

  Here, functions executed in (1) normal imaging, (3) contrast imaging film interlocking, and (7) 3D processing (image processing) have been described, but other operations are also shown in the table of FIG. In addition, all functions of the medical device 3 are not executed, and functions related to each operation are executed.

  In this embodiment, whether the requested maintenance can be performed during the operation of the medical device 3 at the time of the maintenance request using the related function list table indicating the function executed in each operation and the function not executed. Whether or not the requested maintenance can be performed may be determined using the flowcharts (workflows) shown in FIGS. 3 to 5.

  The operation status confirmation unit 33 confirms the operation of the medical device 3 when a maintenance request is issued. That is, the operation status confirmation unit 33 confirms what operation the medical device 3 performs. For example, the operation status confirmation unit 33 is configured so that the medical device 3 has (1) normal imaging, (2) contrast imaging, (3) contrast imaging film linkage, (4) imaging condition setting, (5) shown in the table of FIG. Check which operation is to be executed: file operation, (6) film output, (7) 3D processing (image processing), or (8) reconstruction reconstruction.

  The maintenance availability determination unit 34 determines whether the maintenance requested remotely from the maintenance terminal 51 can be performed during the operation of the medical device 3 when the maintenance is requested. In other words, the maintenance availability determination unit 34 determines whether or not maintenance for the function for performing remote maintenance (maintenance target function) at the maintenance terminal 51 can be performed during the operation of the medical device 3 when the maintenance execution request is made. To do. At this time, the maintenance availability determination unit 34 confirms the operation status confirmation unit 33, the operation of the medical device 3 when the maintenance is requested, and the related function list table stored in the related function list table storage unit 35. Based on the above, during the operation, it is determined whether or not maintenance for the function (maintenance target function) for performing remote maintenance at the maintenance terminal 51 can be performed.

  In the related function list table, functions executed in each operation of the medical device 3 are shown. In other words, the related function list table indicates functions (processes) that can be maintained in each operation of the medical apparatus 3.

  Therefore, the maintenance availability determination unit 34 acquires information indicating the operation of the medical device 3 at the time of the maintenance execution request from the operation status confirmation unit 33 and refers to the related function list table, so that the maintenance terminal In 51, it can be determined whether or not maintenance can be performed on a function for performing remote maintenance (function to be maintained).

  For example, the maintenance availability determination unit 34 acquires information indicating the operation of the medical device 3 at the time when maintenance is requested from the operation status confirmation unit 33 and refers to the related function list table to execute the operation. The function is searched, and it is determined whether or not the searched function includes a function for performing remote maintenance (maintenance target function) at the maintenance terminal 51.

  When the function for performing remote maintenance (maintenance target function) at the maintenance terminal 51 is included in the function executed in the operation of the medical device 3 at the time when the maintenance is requested, the function for performing remote maintenance (maintenance target) Is a function scheduled to be executed in the operation, the maintenance availability determination unit 34 determines that maintenance cannot be performed on the maintenance target function.

  On the other hand, when the function of performing remote maintenance (maintenance target function) at the maintenance terminal 51 is not included in the function executed in the operation of the medical device 3 at the time when the maintenance is requested, the function of performing remote maintenance (maintenance) Since the target function) is a function that is not executed in the operation, the maintenance availability determination unit 34 determines that maintenance can be performed on the maintenance target function.

  For example, when the operation of the medical device 3 confirmed by the operation status confirmation unit 33 is (1) normal imaging, according to the related function list table, (A) patient registration function, (B) imaging condition setting function, and (C) The imaging function is scheduled to be executed, (E) the film output function is undecided, (D) contrast imaging function, (F) file operation function, (G) 3D processing (image processing) function, and (H) The service log acquisition function is not used.

  In this case, when the function (maintenance target function) for performing remote maintenance at the maintenance terminal 51 is a patient registration function, an imaging condition setting function, or an imaging function, (1) Since the function is executed, the maintenance availability determination unit 34 determines that maintenance for the maintenance target function cannot be performed.

  On the other hand, when the function for performing remote maintenance at the maintenance terminal 51 (maintenance target function) is a contrast imaging function, a file operation function, a 3D processing (image processing) function, or a service log acquisition function, (1) normal Since these functions are not executed in the photographing operation, the maintenance availability determination unit 34 determines that maintenance can be performed on the maintenance target function.

  Further, when the function of performing remote maintenance (maintenance target function) at the maintenance terminal 51 is a film output function, (1) In the normal shooting operation, the function may be executed or executed. In some cases, the maintenance availability determination unit 34 determines whether maintenance can be performed on the maintenance target function according to the operator's determination.

  When it is determined that the maintenance requested by the maintenance terminal 51 can be performed, a maintenance request is sent from the maintenance availability determination unit 34 to the request processing unit 36, and the request processing unit 36 performs maintenance according to the request. carry out. For example, when the maintenance requested by the maintenance terminal 51 is acquisition of a service log, the request processing unit 36 acquires a service log stored in the medical device 3 and transmits the service log stored in the medical device 3 via the network. To the maintenance terminal 51 installed in

  On the other hand, when it is determined that the maintenance requested by the maintenance terminal 51 cannot be performed, the maintenance availability determination unit 34 indicates that the maintenance is not possible and is installed in the remote maintenance device 5 via the network. To the maintenance terminal 51. The display device of the maintenance terminal 51 displays that the request is impossible.

  When it is determined that the maintenance requested by the maintenance terminal 51 can be performed, the request processing unit 36 performs the requested maintenance. For example, the request processing unit 36 performs upgrade of each function (software), parameter setting change, service log acquisition, and the like.

  The medical device 3 includes a CPU (not shown) and a storage device such as a ROM, RAM, and HDD. The storage device executes an operation status confirmation program for executing processing by the operation status confirmation unit 33, a maintenance availability determination program for executing processing by the maintenance availability determination unit 34, and processing by the request processing unit 36. A request processing program is stored.

  Then, the CPU reads the operation status confirmation program from the storage device and executes it to confirm the operation of the medical device 3. Further, the CPU reads and executes the maintenance availability determination program from the storage device, thereby determining whether or not the maintenance requested by the maintenance terminal 51 can be executed. The CPU executes the maintenance requested from the maintenance terminal 51 by reading and executing the request processing program from the storage device.

(Operation)
Next, a series of operations by the medical system 1 according to the first embodiment of the present invention will be described with reference to FIG. FIG. 6 is a flowchart showing a series of operations by the medical system according to the first embodiment of the present invention.

(Step S30)
First, the operator uses the maintenance terminal 51 installed in the remote maintenance device 5 to request maintenance. For example, the maintenance terminal 51 is used to request acquisition of a service log of the medical device 3 or upgrade of a certain function. Here, the case where the service log of the medical device 3 is acquired will be described. The maintenance execution request given by the maintenance terminal 51 is transmitted to the medical apparatus 3 via the network.

(Step S31)
When a maintenance execution request is made at the maintenance terminal 51, the processing request reception unit 32 of the medical device 3 receives the maintenance execution request transmitted from the maintenance terminal 51. The process request receiving unit 32 outputs the received request to the maintenance availability determination unit 34.

(Step S32)
The maintenance availability determination unit 34 acquires information indicating the operation of the medical device 3 at the time of the maintenance request from the operation status confirmation unit 33. Here, the operation of the medical device 3 is assumed to be normal imaging.

(Step S33)
Further, the maintenance availability determination unit 34 acquires a related function list table from the related function list table storage unit 35.

(Step S34)
Then, the maintenance availability determination unit 34 refers to the related function list table based on the request from the maintenance terminal 51 and the operation of the medical device 3, so that the operation of the medical device 3 at the time of the maintenance execution request is performed. It is determined whether or not the maintenance requested by the maintenance terminal 51 can be performed.

  For example, when the operation of the medical device 3 is (1) normal imaging shown in the table of FIG. 2 and the function of performing remote maintenance at the maintenance terminal 51 (maintenance target function) is a service log acquisition function, Since the service log acquisition function is a function that is not executed in (1) normal imaging, the maintenance availability determination unit 34 determines that remote maintenance can be executed. The maintenance availability determination unit 34 then sends a maintenance execution request to the request processing unit 36. In this case, the maintenance availability determination unit 34 sends a service log acquisition request to the request processing unit 36.

  On the other hand, if the function for performing remote maintenance at the maintenance terminal 51 (maintenance target function) is, for example, an imaging function, the imaging function is a function executed in (1) normal imaging, and therefore a maintenance availability determination unit 34 determines that remote maintenance cannot be performed. Then, the maintenance availability determination unit 34 transmits to the maintenance terminal 51 that the requested maintenance cannot be performed.

(Step S35)
When the maintenance terminal 51 receives that the maintenance cannot be performed, the maintenance terminal 51 displays the fact that the maintenance is impossible on the display device. Thereby, the operator of the maintenance terminal 51 can recognize that remote maintenance cannot be performed during the current operation of the medical apparatus 3.

(Step S36)
On the other hand, when it is determined that the maintenance requested by the maintenance terminal 51 can be performed, the request processing unit 36 receives the maintenance execution request and performs the maintenance. For example, when acquisition of a service log is requested, the request processing unit 36 acquires the service log of the device stored in the medical device 3 and transmits the service log to the maintenance terminal 51 via the network.

(Step S37)
When the maintenance terminal 51 receives the service log from the medical device 3, the maintenance terminal 51 displays the service log on the display device.

  As described above, according to the medical system 1 according to the first embodiment, even if the medical device 3 is in operation, it is possible to specify a function capable of performing remote maintenance under the operation status, and maintenance is possible. For remote functions, remote maintenance can be performed. Therefore, since it is possible to perform remote maintenance of the medical device 3 without stopping all functions, it is possible to reduce the time during which the medical device 3 is stopped and improve the operating rate of the medical device 3. It becomes.

  For example, it is not necessary to stop the operation of the medical device 3 just to acquire the service log at the maintenance terminal 51, and the service log can be acquired while the medical device 3 is operating. The rate can be improved.

(Modification)
Next, a modification of the medical system 1 according to the first embodiment of the present invention will be described with reference to FIG. FIG. 7 is a flowchart showing a series of operations according to a modification of the medical system according to the first embodiment of the present invention.

  In this modification, a case will be described in which the function that is the target of remote maintenance requested from the maintenance terminal 51 is a function that is selectively executed in the operation of the medical apparatus 3 at the time when the maintenance is requested.

(Step S40)
First, the operator uses the maintenance terminal 51 installed in the remote maintenance device 5 to request maintenance. Here, a case where maintenance of the film output function is performed will be described. The maintenance execution request given by the maintenance terminal 51 is transmitted to the medical apparatus 3 via the network.

(Step S41)
When a maintenance execution request is made at the maintenance terminal 51, the processing request reception unit 32 of the medical device 3 receives the maintenance execution request transmitted from the maintenance terminal 51. The process request receiving unit 32 outputs the received request to the maintenance availability determination unit 34.

(Step S42)
The maintenance availability determination unit 34 acquires information indicating the operation of the medical device 3 at the time of the maintenance request from the operation status confirmation unit 33. Here, the operation of the medical device 3 is assumed to be normal imaging.

(Step S43)
Further, the maintenance availability determination unit 34 acquires a related function list table from the related function list table storage unit 35.

(Step S44)
Then, the maintenance availability determination unit 34 refers to the related function list table based on the request from the maintenance terminal 51 and the operation of the medical device 3, so that the operation of the medical device 3 at the time of the maintenance execution request is performed. It is determined whether or not the maintenance requested by the maintenance terminal 51 can be performed.

  For example, when the operation of the medical device 3 is (1) normal imaging shown in the table of FIG. 2 and the function of performing remote maintenance (maintenance target function) at the maintenance terminal 51 is a film output function, Since the output function is (1) a function that has not yet been implemented in normal shooting, the maintenance availability determination unit 34 transmits to the maintenance terminal 51 that the film output function is a function that is selectively implemented.

(Step S45)
When the maintenance terminal 51 receives that the function to be maintained (film output function) is selectively executed in the operation of the medical device 3 at the time when maintenance is requested, the maintenance terminal 51 displays that fact on the display device. Thereby, the operator of the maintenance terminal 51 can recognize that the maintenance target function (film output function) may be executed during the current operation of the medical apparatus 3.

  Then, the operator uses the maintenance terminal 51 to instruct the maintenance to be performed or stopped. The instruction given by the maintenance terminal 51 is transmitted to the medical device 3 via the network.

(Step S46)
The process request receiving unit 32 receives the maintenance execution or cancellation instruction transmitted from the maintenance terminal 51 and transmits the instruction to the maintenance availability determination unit 34.

(Step S47)
When the instruction given by the maintenance terminal 51 is the execution of maintenance, the maintenance availability determination unit 34 sends a maintenance execution request to the request processing unit 36.

  On the other hand, if the instruction given by the maintenance terminal 51 is to stop maintenance, the maintenance availability determination unit 34 ends the series of processing without sending a maintenance execution request to the request processing unit 36.

(Step S48)
When the instruction given by the maintenance terminal 51 is a maintenance execution request, the request processing unit 36 receives the maintenance execution request and performs the maintenance. For example, when an upgrade of the film output function is requested, the request processing unit 36 upgrades the film output function.

(Step S49)
When maintenance is performed by the request processing unit 36, the processing result is transmitted to the maintenance terminal 51. For example, when the function is upgraded, the request processing unit 36 transmits an upgrade completion message to the maintenance terminal 51. The maintenance terminal 51 displays on the display device the end of the upgrade. If the request at the maintenance terminal 51 is acquisition of a service log, the request processing unit 36 transmits the service log acquired from the medical device 3 to the maintenance terminal 51. The maintenance terminal 51 displays the service log on the display device.

  As described above, according to the medical system according to this modification, the selectively executed functions are maintained according to the judgment of the operator of the maintenance terminal 51. As described above, regarding functions that are selectively executed and functions that can be maintained, remote maintenance can be performed even when the medical apparatus 3 is in operation. Therefore, maintenance can be performed while the medical device 3 is operating, so that the operating rate of the medical device 3 can be improved.

(D) Contrast imaging function, (F) File operation function (G) 3D processing (image processing) function, and (H) Service log acquisition function are not used. ing. Accordingly, the (D) contrast imaging function, (F) file operation function (G) 3D processing (image processing) function, and (H) service log acquisition function can be maintained. Create a list of features that are enabled. Then, the list creation unit 37 transmits the list data to the maintenance terminal 51 via the network. Further, the list creation unit 37 may include a function whose execution is undetermined in the list data. For example, in the case of (1) normal shooting, since (E) film output function has not been executed yet, the list creation unit 37 may include (E) film output function in the list data.

  The maintenance terminal 51 displays a list of functions that can be maintained on the display device. An example of a list of functions displayed on this display device is shown in FIG. (1) In normal imaging, (D) contrast imaging function, (F) file operation function (G) 3D processing (image processing) function, and (H) service log acquisition function can be maintained. As shown in FIG. 9, a list of these functions is displayed on the display device of the maintenance terminal 51.

  Then, the operator refers to a list of functions displayed on the display device of the maintenance terminal 51 and selects a function to be maintained from the list. For example, when it is desired to maintain the (H) service log acquisition function shown in FIG. 9, the (H) service log acquisition function is selected from the list displayed on the display device, and (H) the service log acquisition function is maintained for medical use. Request to device 3. As a result, the request processing unit 36 performs maintenance of the service log acquisition function.

Similar to the medical device 3 according to the first embodiment, the storage device stores an operation status confirmation program and a request processing program. In the second embodiment, a list creation program for executing processing by the list creation unit 37 is stored in the storage device. The CPU reads a list creation program from the storage device and executes it to create a list of functions that can be maintained.

(Operation)
Next, a series of operations by the medical system according to the second embodiment of the present invention will be described with reference to FIG.

(Step S50)
First, the operator uses the maintenance terminal 51 installed in the remote maintenance device 5 to request acquisition of a list of functions that can be maintained. The acquisition request given by the maintenance terminal 51 is transmitted to the medical device 3B via the network.

(Step S51)
The processing request reception unit 32 of the medical device 3 </ b> A receives the request for acquiring a list of functions that can be maintained transmitted from the maintenance terminal 51. The process request accepting unit 32 outputs the accepted request to the list creating unit 37.

(Step S52)
The list creation unit 37 acquires information indicating the operation of the medical device 3 </ b> A at the time of the list acquisition request from the operation status confirmation unit 33. Here, the operation of the medical device 3A is assumed to be normal imaging.

Furthermore, the list creation unit 37 acquires a related function list table from the related function list table storage unit 35.

(Step S54)
The list creation unit 37 then refers to the related function list table based on the operation of the medical device 3A at the time of the list acquisition request, and generates a list of functions that can be maintained during the operation.

  For example, when the operation of the medical device 3A is (1) normal imaging shown in the table of FIG. 2, (A) patient registration function, (B) imaging condition setting function, and (C) imaging function are executed. E) The film output function has not been executed yet. (D) Contrast imaging function, (F) File operation function (G) 3D processing (image processing) function, and (H) Service log acquisition function are not used. ing. Accordingly, the (D) contrast imaging function, (F) file operation function (G) 3D processing (image processing) function, and (H) service log acquisition function can be maintained. Create a list of features that are enabled. Then, the list creation unit 37 transmits the list data to the maintenance terminal 51 via the network. Moreover, the list creation unit 37 may include (E) a film output function whose execution has not been determined in the list.

(Step S55)
When the maintenance terminal 51 receives the list of functions that can be maintained, the maintenance terminal 51 displays the list of functions on the display device as shown in FIG. As a result, the operator of the maintenance terminal 51 can grasp the functions that can be maintained during the current operation of the medical apparatus 3B.

It becomes possible.

[Third Embodiment]
Next, a medical device system and a medical device according to a third embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a block diagram showing a schematic configuration of a medical system according to the third embodiment of the present invention. FIG. 12 is a table showing an example of the maintenance related function list table. FIG. 13 is an example of a table displayed on the terminal. FIG. 14 is a flowchart showing a series of operations by the medical apparatus according to the third embodiment of the present invention.

  The medical device 3B according to the third embodiment creates a list of functions that are not related to the maintenance target when remote maintenance is performed on the medical device. Can be executed.

  The medical device 3B according to the third embodiment includes a maintenance status confirmation unit 38 instead of the operation status confirmation unit 33 provided in the medical device 3 according to the first embodiment shown in FIG. Instead of this, a list creation unit 37 is provided. The related function list table storage unit 39 stores a table different from the first embodiment. Since the other configuration of the medical device 3B is the same as the configuration of the medical device 3 according to the first embodiment, the description thereof is omitted.

  The related function list table storage unit 39 stores a maintenance related function list table indicating maintenance performed on the medical apparatus 3B and functions that can be executed when the maintenance is performed. This maintenance related function list table is created in advance and stored in the related function list table storage unit 39.

  This maintenance-related function list table is a criterion for determining whether or not the function requested to be executed can be executed during the maintenance of the medical apparatus 3B at the time of the list acquisition request. For example, if a function requested to be executed on the operation terminal 31 corresponds to a maintenance target function during certain maintenance, it is determined that the requested function cannot be executed. On the other hand, if the function requested to be executed on the operation terminal 31 does not correspond to the maintenance target function during a certain maintenance, it is determined that the requested function can be executed.

  An example of the maintenance related function list table is shown in FIG. When the medical apparatus 3B is an X-ray CT apparatus, examples of maintenance performed on the medical apparatus 3B include (1) patient registration system maintenance, (2) imaging system maintenance, and (3) file operation system maintenance. This includes maintenance, (4) film system maintenance, (5) 3D processing (image processing) system maintenance, and (6) log acquisition system maintenance. The maintenance content illustrated in FIG. 12 is an example of maintenance performed on the medical apparatus 3B as the X-ray CT apparatus, and maintenance other than the maintenance illustrated in FIG. 12 is performed on the medical apparatus 3B.

  The maintenance-related function list table shows functions that can be executed during the maintenance of the medical apparatus 3B and functions that cannot be executed. Examples of functions include (A) patient registration function, (B) imaging condition setting function, (C) imaging function, (D) contrast imaging function, (E) film output function, (F) file operation function, and ( G) A 3D processing (image processing) function or the like is applicable. Functions that can be executed in the maintenance-related function list table are functions that can be executed even during remote maintenance. A function that cannot be executed is a function that cannot be executed during remote maintenance.

  For example, in (1) maintenance of a patient registration system, (B) imaging condition setting function, (E) film output function, (F) file operation function, and (G) 3D processing (image processing) function are subject to maintenance. Therefore, it can be executed even during remote maintenance. That is, in (1) patient registration system maintenance, (A) patient registration function, (C) imaging function, and (D) contrast imaging function are the targets of maintenance, and function upgrades, parameter changes, etc. are performed. .

  On the other hand, (1) In the maintenance of the patient registration system, (A) the patient registration function, (C) the imaging function, and (D) the contrast imaging function are maintenance targets. It is possible.

  As described above, in (1) patient registration system maintenance, not all functions of the medical device 3 are executable, and (1) functions related to patient registration system maintenance are not performed. Unrelated functions can be executed.

  Here, (1) the functions that can be executed and the functions that cannot be executed in the maintenance of the patient registration system have been described. In other maintenance situations, as shown in the table of FIG. The function is not disabled, the function related to each maintenance becomes unexecutable, and the unrelated function can be executed.

  The maintenance status confirmation unit 38 confirms the maintenance performed on the medical device 3B when the list acquisition request is made. That is, the maintenance status confirmation unit 38 confirms what kind of maintenance is performed on the medical device 3B at the time of the list acquisition request. For example, the maintenance status confirmation unit 38, for the medical device 3B, shows (1) patient registration system maintenance, (2) imaging system maintenance, (3) file operation system maintenance shown in the table of FIG. It is confirmed whether maintenance is performed among 4) film system maintenance, (5) 3D processing system maintenance, or (6) log acquisition system maintenance.

  In addition, the list creation unit 37 creates a list of functions that can be executed during the maintenance performed on the medical device 3B at the time of the list acquisition request. At this time, the list creation unit 37 creates a list based on the maintenance for the medical device 3B confirmed by the maintenance status confirmation unit 38 and the maintenance related function list table stored in the maintenance related function list table storage unit 39. A list of functions that can be executed during maintenance performed on the medical device 3B at the time of acquisition request is created.

  The maintenance-related function list table shows functions that can be executed during remote maintenance and functions that cannot be executed. Therefore, the list creation unit 37 acquires information indicating the maintenance performed on the medical device 3B at the time of the list acquisition request from the maintenance status confirmation unit 38, and refers to the maintenance related function list table, so that the maintenance is performed. A list of functions that can be executed can be created.

  Then, the list creation unit 37 sends data of a list of executable functions to the operation terminal 31. The operation terminal 31 displays a list of executable functions on the display device. The operator refers to a list of functions displayed on the display device of the operation terminal 31, and if there is a function to be executed, selects the function from the list and requests the medical apparatus 3B to execute the function. The processing request receiving unit 32 receives a function execution request sent from the operation terminal 31 and outputs the execution request to the request processing unit 36. The request processing unit 36 executes a function requested to be executed.

  For example, when (2) photographing system maintenance is performed, the list creation unit 37 creates a list of functions executable in (2) photographing system maintenance by referring to the maintenance-related function list table. . As shown in FIG. 12, (2) in imaging system maintenance, (A) patient registration function, (E) film output function, (F) file operation function, and (G) 3D processing function (image processing function) Can be executed, the list creation unit 37 creates a list of those functions. Then, the list creation unit 37 sends the list data to the operation terminal 31.

  The operation terminal 31 displays a list of executable functions on the display device. An example of a list of functions displayed on this display device is shown in FIG. (2) In imaging system maintenance, (A) patient registration function, (E) film output function, (F) file operation function, and (G) 3D processing function (image processing function) can be executed. As shown in FIG. 13, a list of these functions is displayed on the display device of the operation terminal 31.

  Then, the operator refers to a list of functions displayed on the display device of the operation terminal 31, and selects an executed function from the list. For example, when it is desired to execute the (A) patient registration function shown in FIG. 13, (A) the patient registration function is selected from the list displayed on the display device, and (A) the patient registration function is executed to the medical device 3B. Request. Accordingly, the request processing unit 36 executes the patient registration function, and the operator can perform patient registration using the operation terminal 31, for example.

  The medical device 3B includes a CPU (not shown) and a storage device. The storage device stores a maintenance status confirmation program for executing processing by the maintenance status confirmation unit 38, a list creation program for executing processing by the list creation unit 37, and a request processing program. The CPU reads the maintenance status confirmation program from the storage device and executes it to check the maintenance for the medical device 3B, and the list creation program is read and executed to create a list of functions that can be executed during the maintenance. To do.

(Operation)
Next, a series of operations by the medical device 3B according to the third embodiment of the present invention will be described with reference to the flowchart of FIG.

(Step S60)
First, the operator uses the operation terminal 31 to request acquisition of a list of functions that can be executed even during maintenance of the medical device 3B.

(Step S61)
When a request for acquiring a list of functions that can be executed by the operation terminal 31 is made, the processing request receiving unit 32 receives the request. The process request accepting unit 32 outputs the accepted request to the list creating unit 37.

(Step S62)
The list creation unit 37 acquires information indicating maintenance performed on the medical device 3B at the time of the list acquisition request from the maintenance status confirmation unit 38. Here, the maintenance of the medical apparatus 3B is the maintenance of the imaging system.

(Step S63)
Further, the list creation unit 37 acquires a maintenance related function list table from the related function list table storage unit 39.

(Step S64)
Then, the list creation unit 37 refers to the maintenance-related function list table based on the maintenance performed on the medical device 3B at the time of the list acquisition request, thereby obtaining a list of functions that can be executed during the maintenance. create.

  For example, when the maintenance of the medical apparatus 3B is (2) imaging system maintenance shown in the table of FIG. 12, in (2) imaging system maintenance, (A) patient registration function, (E) film output function Since (F) file operation function and (G) 3D processing function (image processing function) can be executed, the list creation unit 37 creates a list of these functions. Then, the list creation unit 37 outputs the list data to the operation terminal 31.

(Step S65)
When the operation terminal 31 receives the list of executable functions, the operation terminal 31 displays the list of functions on the display device as shown in FIG. As a result, the operator of the operation terminal 31 can grasp the functions that can be executed during the maintenance of the current medical apparatus 3B.

  Then, the operator refers to the list of functions displayed on the display device of the operation terminal 31, selects a function to be executed from the list, and gives an execution request for the function to the medical apparatus 3B. For example, when (A) the patient registration function is specified by the operator in the list shown in FIG. 13, (A) an execution request for the patient registration function is sent from the operation terminal 31 to the processing request receiving unit 32.

(Step S66)
The processing request receiving unit 32 receives a function execution request given from the operation terminal 31 and sends the execution request to the request processing unit 36.

(Step S67)
The request processing unit 36 receives the execution request given from the operation terminal 31 and executes the request. For example, when an execution request for the (A) patient registration function is given at the operation terminal 31, the request processing unit 36 executes the patient registration function. Thereby, patient registration is possible at the operation terminal 31.

  As described above, according to the medical device 3B according to the third embodiment, even if the medical device 3B is under maintenance, the functions that can be executed during the maintenance can be specified. It becomes possible to execute. Therefore, since the predetermined function can be executed while maintaining the medical device 3B, it is possible to reduce the time during which the medical device 3B is stopped and to improve the operation rate.

[Fourth Embodiment]
Next, a medical system according to a fourth embodiment of this invention will be described with reference to FIG. FIG. 15 is a table showing an example of an executable function list table for each operator of the medical apparatus.

  The medical system according to the fourth embodiment determines whether or not remote maintenance is possible based on the authority of the operator who is using the medical device when maintenance is requested.

  The medical system according to the fourth embodiment has the same configuration as that of the medical system 1 according to the first embodiment, but the related function list table storage unit 35 includes the related function list table shown in FIG. An executable function list table for each operator of the medical apparatus 3 is stored.

  The executable function list table of each operator of the medical apparatus 3 stored in the related function list table storage unit 35 will be described with reference to FIG. The executable function list table shown in FIG. 15 shows functions that can be executed by each operator who uses the medical apparatus 3. In other words, functions that can be executed by individual operators are limited depending on the operator's authority, and the executable function list table is created based on the operator's authority and can be executed for each operator. The possible functions are shown.

  For example, as shown in FIG. 15, the doctor A uses the medical device 3 to (A) a patient registration function, (B) an imaging condition setting function, (C) an imaging function, (D) a contrast imaging function, and (E) a film. The output function, (F) file operation function, and (G) 3D processing function (image processing function) can be executed, but the (H) service log acquisition function cannot be executed. On the other hand, the doctor B executes (A) a patient registration function, (B) an imaging condition setting function, (C) an imaging function, (E) a film output function, and (F) a file operation function in the medical device 3. However, (D) contrast imaging function, (G) 3D processing function (image processing function), and (H) service log acquisition function cannot be executed. Thus, the functions that can be executed vary depending on the operator.

  The maintenance availability determination unit 34 searches for a function that can be executed by the operator based on the operator of the medical apparatus 3 and the executable function list table when the maintenance is requested. For example, when operator identification information (operator ID) for identifying the operator of the medical device 3 is input at the operation terminal 31, the maintenance availability determination unit 34 refers to the executable function list table. A function that can be executed by the operator specified by the operator identification information is searched.

  Then, the maintenance availability determination unit 34 determines whether the function (maintenance target function) for which remote maintenance is performed at the maintenance terminal 51 is a function that can be executed by the operator of the medical device 3 when the maintenance is requested. Judging. If the maintenance target function cannot be executed with the authority of the operator of the medical apparatus 3 at the time when maintenance is requested, the maintenance target function is not executed. It is determined that the maintenance requested at the terminal 51 can be performed.

  On the other hand, with the authority of the operator of the medical device 3 at the time when maintenance is requested, if the maintenance target function can be executed, the maintenance target function may be executed. In this case, as in the first embodiment, the maintenance availability determination unit 34 refers to the related function list table shown in FIG. 2 to determine whether or not the maintenance requested by the maintenance terminal 51 can be performed. Judging.

  As described above, according to the medical system according to the fourth embodiment, by determining whether remote maintenance from the maintenance terminal 51 is possible based on the authority of the operator of the medical device 3 at the time when maintenance is requested, Maintenance can be performed for a predetermined function while the apparatus 3 is operating. Therefore, it is possible to reduce the time during which the medical device 3 is stopped and improve the operating rate of the medical device 3.

[Fifth Embodiment]
Next, a medical system according to a fifth embodiment of the invention will be described with reference to FIG. FIG. 16 is a flowchart showing a series of operations by the medical system according to the fifth embodiment of the present invention.

  In the first embodiment, the maintenance availability determination unit 34 determines whether or not the maintenance requested by the maintenance terminal 51 can be performed by referring to the related function list table shown in FIG. On the other hand, in the fifth embodiment, the maintenance availability determination unit 34 determines whether the maintenance requested by the maintenance terminal 51 can be performed based on the function (application) being executed in the medical device 3. Judging.

  For example, the operation status confirmation unit 33 confirms the function (application) being executed in the medical device 3 at the time of the maintenance execution request. Based on the function (application) being executed in the medical device 3, the maintenance availability determination unit 34 will perform a function (maintenance target function) to be performed remotely on the maintenance terminal 51 in the medical device 3 in the future. Determine whether it is a plan. When the maintenance target function is scheduled to be executed in the future by the medical apparatus 3, the maintenance availability determination unit 34 determines that the maintenance requested by the maintenance terminal 51 cannot be performed. On the other hand, if the function to be maintained is not scheduled to be executed in the medical device 3 in the future, the maintenance availability determination unit 34 determines that the maintenance requested by the maintenance terminal 51 can be performed.

  For example, a workflow indicating the order in which each function is executed in the medical device 3 is stored in the related function list table storage unit 35 in advance. For example, in normal imaging, each function is executed in the order of patient registration, imaging condition setting, imaging, and film output. Therefore, the order of these functions is shown as the normal imaging workflow. The maintenance availability determination unit 34 refers to the workflow indicating the execution order of each function based on the request from the maintenance terminal 51 and the function (application) being executed in the medical device 3, thereby maintaining the maintenance terminal 51. It is determined whether or not the requested maintenance can be executed.

  If the function for performing remote maintenance (maintenance target function) at the maintenance terminal 51 by referring to the workflow on the basis of the function (application) being executed by the medical device 3 is a function that has been executed, maintenance is performed. The availability determination unit 34 determines that the maintenance target function can be maintained. The maintenance availability determination unit 34 then sends a maintenance execution request to the request processing unit 36.

  On the other hand, when the function to be maintained is executed after the function (application) being executed, the function to be maintained is scheduled to be executed from now on, so the maintenance availability determination unit 34 performs maintenance on the function to be maintained. Judge that it is impossible. Then, the maintenance availability determination unit 34 transmits to the maintenance terminal 51 via the network that the requested maintenance cannot be performed.

(Operation)
The operation of the medical system according to the fifth embodiment will be described below with reference to the flowchart in FIG.

(Step S70)
First, the operator uses the maintenance terminal 51 installed in the remote maintenance device 5 to request maintenance. Here, a case where maintenance of the patient registration function is performed will be described. The maintenance execution request given by the maintenance terminal 51 is transmitted to the medical apparatus 3 via the network.

(Step S71)
When a maintenance execution request is made at the maintenance terminal 51, the processing request reception unit 32 of the medical device 3 receives the maintenance execution request transmitted from the maintenance terminal 51. The process request receiving unit 32 outputs the received request to the maintenance availability determination unit 34.

(Step S72)
The maintenance availability determination unit 34 acquires information indicating the function (application) being executed by the medical device 3 at the time of the maintenance execution request from the operation status confirmation unit 33. Here, the function (application) being executed is defined as a shooting function.

(Step S73)
Further, the maintenance availability determination unit 34 acquires a workflow indicating the order in which each function is executed in the medical device 3 from the related function list table storage unit 35.

(Step S74)
The maintenance availability determination unit 34 is requested by the maintenance terminal 51 by referring to the workflow indicating the execution order of each function based on the request from the maintenance terminal 51 and the function (application) being executed. Judge whether or not maintenance can be performed.

  If the function for performing remote maintenance at the maintenance terminal 51 (maintenance target function) is an already executed function, the maintenance availability determination unit 34 determines that the maintenance target function can be maintained. The maintenance availability determination unit 34 then sends a maintenance execution request to the request processing unit 36. On the other hand, when the maintenance target function is executed after the function (application) being executed, the maintenance availability determination unit 34 determines that the maintenance of the maintenance target function is impossible. Then, the maintenance availability determination unit 34 transmits to the maintenance terminal 51 that the requested maintenance cannot be performed.

  For example, when maintenance of the patient registration function is requested at the maintenance terminal 51 and the function (application) currently being executed is an imaging function, the patient registration function is executed before the imaging function is executed. Since it is being executed, the maintenance availability determination unit 34 determines that maintenance for the patient registration function is possible. On the other hand, if maintenance of the film output function is requested at the maintenance terminal 51 and the function (application) currently being executed is a shooting function, the film output function is executed after the shooting function is executed. Therefore, the maintenance availability determination unit 34 determines that maintenance for the film output function is impossible.

(Step S75)
When the maintenance terminal 51 receives that the maintenance cannot be performed, the maintenance terminal 51 displays the fact that the maintenance is impossible on the display device. Thereby, the operator of the maintenance terminal 51 can recognize that the remote maintenance cannot be performed under the current operation state of the medical device 3.

(Step S76)
On the other hand, when it is determined that the requested maintenance can be performed, the request processing unit 36 receives the maintenance execution request from the maintenance availability determination unit 34 and performs the maintenance. For example, when an upgrade is requested as maintenance of the patient registration function, the request processing unit 36 upgrades the patient registration function.

  As described above, according to the medical system according to the fifth embodiment, as in the first embodiment, the medical device 3 can be maintained while the medical device 3 is operated. The rate can be improved. Further, whether or not remote maintenance can be performed dynamically is determined by determining whether or not the maintenance requested by the maintenance terminal 51 can be performed based on the function (application) currently being executed in the medical device 3. Can be judged.

  In the first to fifth embodiments, the medical apparatus has been described as an X-ray CT apparatus. However, in addition to the X-ray CT apparatus, an MRI apparatus, an ultrasonic diagnostic apparatus, an X-ray diagnostic apparatus, a nuclear medicine diagnostic apparatus, or the like Even so, the same actions and effects can be achieved.
