As a result, the user can select “sent to DICOM Server” displayed on the right side of the check column 47 in FIG. 7 as one of the inspection end conditions set by the inspection end condition dialog 41. . “Transmitted to DICOM Server” displayed on the right side of the check column 47 in FIG. 7 indicates that the image data acquired by the medical image diagnostic apparatus 14 is connected to the DICOM Server (for example, the hospital network system 11). This means that the image has been transmitted to a medical image storage server (not shown), and when the image acquired by the medical image diagnostic apparatus 14 is transmitted to the DICOM Server, the examination end process is started. .

  The user can check the check field 48 by operating a keyboard (not shown) or a mouse (not shown) of the input unit 22. Accordingly, the user can select “sent to DICOM Printer” displayed on the right side of the check column 48 in FIG. 7 as one of the inspection end conditions set by the inspection end condition dialog 41. . “Sent to DICOM Printer” displayed on the right side of the check column 48 in FIG. 7 is for causing the DICOM Printer (for example, a printer (not shown) connected to the hospital network system 11) to print an image. This means that the image data acquired by the medical image diagnostic apparatus 14 has been transmitted to the DICOM Printer, and the image data acquired by the medical image diagnostic apparatus 14 is transmitted to the DICOM Printer in order to cause the DICOM Printer to print an image. This means that the inspection end process is started.

  The command display field 54 displays a command icon “register”. The user can instruct registration of the inspection end condition set by the inspection end condition setting dialog 41 by selecting the “registration” icon in the command display field 54.

  In step S5, the control unit 31 operates the keyboard (not shown) or the mouse (not shown) of the input unit 22 based on the examination end condition setting dialog 41 shown in FIG. It is determined whether or not the “registration” icon 54 has been selected, and the user operates the keyboard (not shown) or the mouse (not shown) of the input unit 22 to change the “registration” in the command display field 54. Wait until the icon is selected.

  If it is determined in step S5 that the “registration” icon in the command display field 54 has been selected, the inspection end condition setting unit 34 performs the inspection based on the inspection end condition setting dialog 41 in step S6 in accordance with an instruction from the control unit 31. Set the end condition. That is, in the case of the example of FIG. 7, as the test end conditions, “10 (min)” “FREEZE time”, “10 (min)” “no key input time”, “10 (min)” “user absent” “Detection time”, “Maximum inspection time” of “20 (min)”, “Rest time” of “12: 30-13: 30”, “Sent to DICOM Server”, and “Sent to DICOM Printer” Can be set. Thereby, for example, in the examination of the subject by the medical image diagnostic apparatus 14, the user does not draw an image displayed in real time on the LCD (not shown) or the CRT (not shown) of the output unit 23 for 10 minutes or more for the examination. When stopped by the button, the medical image diagnostic apparatus 14 can start an examination end process (described later with reference to the flowchart of FIG. 10).

  In step S <b> 7, the inspection end condition setting unit 34 supplies inspection end condition setting data, which is setting data of the inspection end condition set by the processing in step S <b> 6, to the inspection end setting condition database 39. In step S8, the inspection end setting condition database 39 acquires the inspection end condition setting data supplied from the inspection end condition setting unit 34, and the acquired inspection end condition setting data is managed in the inspection end condition database 39. Register in the database.

  FIG. 8 shows an example of a database managed by the examination end setting condition database 39 in the storage unit 32.

  The first to seventh columns of the examination end setting condition database 39 in FIG. 8 include “FREEZE time”, “no key input time”, “user absence detection time”, “maximum examination time”, “break time”. "," Sent to DICOM Server ", and" Sent to DICOM Printer ". Since these descriptions are the same as the descriptions in the inspection end condition setting dialog 41 shown in FIG.

  In the case of the first row of the examination end setting condition database 39, the “FREEZE time” is “10 (min)”, and an unillustrated LCD or diagram of the output unit 23 in the examination of the subject by the medical image diagnostic apparatus 14 is shown. The time when the user temporarily stops the image displayed in real time on the CRT (not shown) with a button (not shown) for the inspection (FREEZE time). The time is “10 (min)”. “No key input time” is “10 (min)”, which is a time during which the user does not operate a keyboard (not shown) or a mouse (not shown) of the input unit 22 (no key input time). This indicates that the time without key input for starting the inspection end process when the operation is not performed is “10 (min)”. The “user absence detection time” is “10 (min)”, and is the time (user absence detection time) when it is detected that the user does not exist in front of the medical image diagnostic apparatus 14, and the user further performs medical image diagnosis. When it is detected that it does not exist in front of the device 14, it indicates that the user absence detection time for starting the inspection end process is “10 (min)”.

  The “maximum examination time” is “20 (min)”, and is the maximum examination time (maximum examination time) required for the user to examine one subject using the medical image diagnostic apparatus 14, If it is necessary for the user to further inspect one subject using the medical image diagnostic apparatus 14, the maximum inspection time for starting the inspection end process is “20 (min)”. “Break time” is “12: 30-13: 30”, and the time when the user always leaves the medical image diagnostic apparatus 14 for a break such as a lunch break (break time). It shows that the break time at which the process is started is “12: 30-13: 30”. “Sent to DICOM Server” is “Yes”, “Sent to DICOM Server” is set as an examination end condition, and an image acquired by the medical image diagnostic apparatus 14 is sent to DICOM Server. It indicates that the end process is started. “Sent to DICOM Printer” is “Yes”, “Sent to DICOM Printer” is set as the examination end condition, and the image data acquired by the medical image diagnostic apparatus 14 for printing to the DICOM Printer is Indicates that it is sent to the DICOM Printer.

  Next, the examination end process of the medical image diagnostic apparatus 14 of FIG. 3 will be described with reference to the flowchart of FIG.

  In step S <b> 11, the control unit 31 reads out the database managed in the inspection end setting condition database 39 and supplies it to the inspection end processing unit 33. In step S12, the inspection end processing unit 33 refers to the database supplied from the inspection end setting database 39 via the control unit 31 to determine whether or not a predetermined inspection end setting condition is met. That is, in the case of the example of FIG. 8, in the examination of the subject by the medical image diagnostic apparatus 14, the user takes 10 minutes to examine the image displayed in real time on the LCD (not shown) or the CRT (not shown) of the output unit 23. The inspection end setting condition set in advance is used when the button is stopped by a button (not shown) or when the user does not operate the keyboard (not shown) or the mouse (not shown) of the input unit 22 for 10 minutes or more. Determined to be true.

  If it is determined in step S12 that the preset inspection end setting condition is not met, the process waits until it is determined that the preset examination end setting condition is met.

  If it is determined in step S12 that the preliminarily set inspection end setting condition is satisfied, the inspection end processing unit 33 displays in the output unit 23 an inspection end processing execution advance notice dialog for notifying the user of execution of the inspection end processing in step S13. An inspection end process execution advance notice dialog display control signal for display is generated and supplied to the output unit 23.

  In step S <b> 14, the output unit 23 displays a test end process execution notice dialog 61 as shown in FIG. 10 based on the test end process execution notice dialog display control signal supplied from the test end process part 33.

  FIG. 10 shows a display example of the examination end process execution notice dialog 61 displayed on the output unit 23.

  10 has a message display field 62 and a command display field 63.

  In the case of the example of FIG. 10, the message display field 62 displays a message “Execution end processing is executed after one minute. Please enter any key to cancel”. As a result, when the user completes the examination termination process currently performed by the examination termination process of the medical image diagnostic apparatus 14 one minute later, and cancels the examination termination process, It turns out that it is only necessary to input a key.

  In the command display field 63, an icon of a command “OK” is displayed. The user can operate the keyboard (not shown) or the mouse (not shown) of the input unit 22 to select the “OK” icon in the command display field 63 and instruct execution of the examination end process. it can.

  In step S <b> 15, the control unit 31 determines whether or not an instruction to execute the inspection end process is given based on the inspection end process execution advance notice dialog 61. That is, when the user selects an “OK” icon in the command display field 63 by operating a keyboard (not shown) or a mouse (not shown) of the input unit 22, the control unit 31 checks in step S 15. It is determined that an instruction to execute end processing has been issued.

  If it is determined in step S15 that an instruction to execute the inspection end process has been given, the inspection end processing unit 33 follows the instruction from the control unit 31 in step S16, and “inspection ends for transmission to the HIS 12 via the RIS 13”. Is generated ”and supplied to the communication unit 36. In step S <b> 17, the communication unit 36 acquires the “notification that the inspection is completed” supplied from the inspection end processing unit 33, and sends the notification that the acquired inspection is completed via the network (not shown). Send to.

  In step S18, the inspection end processing unit 33 executes inspection end processing. Specifically, the image displayed on the screen of the output unit 23 provided in the medical image diagnostic apparatus 14 and the measurement result are cleared.

  As described above, since the examination end condition in the medical image diagnostic apparatus 14 is set in advance, even if the user forgets the end operation of the subject examination currently performed in the medical image diagnostic apparatus 14. If a predetermined examination end condition is satisfied, the examination of the subject currently performed in the medical image diagnostic apparatus 14 can be terminated. Thereby, the operativity of the test | inspection completion | finish process in the medical image diagnostic apparatus 14 can be improved. At the same time, it is possible to prevent an unspecified number of people from seeing the examination image of the subject currently being performed in the medical image diagnostic apparatus 14, and as a result, the personal information of the subject is effectively protected. can do.

  If it is determined in step S15 that the instruction to execute the inspection end process has not been issued, the control unit 31 determines whether or not an instruction to cancel the execution of the inspection end process has been issued in step S19. That is, when the user performs any key input by operating any key on the keyboard (not shown) of the input unit 22, the control unit 31 cancels the execution of the inspection end process in step S19. judge.

  When it is determined in step S19 that an instruction to cancel the execution of the inspection end process has been given, the inspection end processing unit 33 cancels the execution of the inspection end process in accordance with the instruction from the control unit 31 in step S20. Thereafter, the process proceeds to step S12, and the processes after step 12 are repeated. As a result, the execution of the examination end process currently being performed by the medical image diagnostic apparatus 14 can be canceled. Accordingly, it is possible to prevent the completion of the examination of the subject even though the subject is being examined against the will of the user, and improve the operability of the medical image diagnostic apparatus 14. be able to.

  Note that after the execution of the examination end process in the medical image diagnostic apparatus 14 is canceled by the user, the examination end process in the medical image diagnostic apparatus 14 may be interrupted for a predetermined time, for example, 5 minutes. Thereby, the user can perform the current operation on the medical image diagnostic apparatus 14 for a predetermined time (for example, 5 minutes) without worrying about the re-execution of the test end process based on the preset test end condition. Further inspection can be continued. Therefore, the operability of the examination end process in the medical image diagnostic apparatus 14 can be further improved.

  If it is determined in step S19 that an instruction to cancel the execution of the inspection end process has not been issued, the process returns to step S15, and then the processes after step S15 are repeated.

  Next, hospital information processing of the HIS 12 of FIG. 3 will be described with reference to the flowchart of FIG.

  In step S <b> 25, the HIS control unit 15 determines whether a notification indicating that the examination is completed is received from the medical image diagnostic apparatus 14. That is, the HIS control unit 15 determines whether or not the HIS communication unit 18 has received a notification from the RIS 13 that the test has been completed via the network.

  When it is determined in step S25 that the notification that the examination has been completed is received, the HIS control unit 15 sends a hospital information processing start control signal for causing the HIS hospital information processing unit 17 to start hospital information processing in step S26. It is generated and supplied to the HIS hospital information processing unit 17.

  In step S <b> 27, the HIS hospital information processing unit 17 starts hospital information processing based on the hospital information processing start control signal supplied from the HIS control unit 15. Specifically, hospital information processing (for example, accounting processing or drug-related processing) is executed on various information acquired from the HIS storage unit 17.

  As described above, in the hospital network system 11 shown in the embodiment of the present invention, even if the user forgets the operation for ending the examination of the subject currently performed in the medical image diagnostic apparatus 14, If the examination end condition set is satisfied, the examination of the subject currently being performed in the medical image diagnostic apparatus 14 is terminated, and a notification that the examination is completed is transmitted to the HIS 12. Hospital information processing can be executed for a test that has been notified that the test has been completed. Thus, the accounting process or the like can be started without having to wait for an unnecessarily long subject to finish the examination and wait for the accounting sooner. Therefore, the throughput of the entire hospital network system 11 can be improved.

  In the medical image diagnostic apparatus 14 shown in the embodiment of the present invention, the sensor 35 detects whether or not the user has moved away from the front of the medical image diagnostic apparatus 14, and sets the user absence detection time as an examination end condition. However, for example, when the user leaves the medical image diagnostic apparatus 14 before the end processing of the examination currently performed in the medical image diagnostic apparatus 14 is executed (that is, the examination is being performed). However, if the user has left the medical image diagnostic apparatus 14 or the like), the user may be notified by an alarm sound that the examination end processing has not been executed. Hereinafter, processing in the medical image diagnostic apparatus 14 in this case will be described.

  FIG. 12 shows another detailed internal configuration of the medical image diagnostic apparatus 14 to which the present invention is applied. 12 is used in the hospital network system 11 in FIG. 3 instead of the medical image diagnostic apparatus 14 in FIG. 5, and the same applies to the HIS 12 and RIS 13 in FIG. Is omitted because it is repeated. 5 that are the same as or correspond to those in the configuration of the medical image diagnostic apparatus 14 shown in FIG. 5 are denoted by the same reference numerals, and the description thereof will not be repeated.

  Based on an instruction from the control unit 31, the alarm sound generation unit 65 generates and stops an alarm sound that notifies the user that the examination end processing has not been executed.

  Next, an examination end process in the medical image diagnostic apparatus 14 of FIG. 12 will be described with reference to the flowchart of FIG. The processes in steps S31 to S40 in FIG. 13 are the same as the processes in steps S11 to S20 in FIG.

  If it is determined in step S32 that the preset inspection end setting condition is not satisfied, the control unit 31 determines whether or not the supply of the detection signal from the sensor 35 is stopped in step S41. That is, the control unit 31 determines whether or not the supply of the detection signal indicating whether or not the user who examines the subject exists in front of the medical image diagnostic apparatus 14 is stopped from the sensor 35.

  When it is determined in step S41 that the supply of the detection signal from the sensor 35 has been stopped (that is, when it is determined that the user has moved away from the front of the medical image diagnostic apparatus 14), the currently completed examination end process is performed. An inspection end unprocessed alarm sound generation control signal for generating an alarm sound for notifying the user that the alarm sound generation section 65 has not been executed is generated and supplied to the alarm sound generation section 65.

  In step S <b> 43, the alarm sound generation unit 65 generates an alarm sound based on the inspection end unprocessed alarm sound generation control signal supplied from the control unit 31. As a result, the user can know that the examination end processing has not yet been executed, for example, when the user leaves the medical image diagnostic apparatus 14 despite the examination being performed. Therefore, even if the user forgets that the end processing of the examination currently being performed in the medical image diagnostic apparatus 14 has not yet been executed, the end processing of the examination is not performed in the medical image diagnostic apparatus 14. It is possible to prevent the device from being left for a while, and the operability of the medical image diagnostic apparatus 14 in the examination end process can be further improved.

  In step S44, the control unit 31 determines whether or not the supply of the detection signal from the sensor 35 has been resumed. That is, the control unit 31 determines whether or not the supply of the detection signal indicating whether or not the user who examines the subject exists in front of the medical image diagnostic apparatus 14 is restarted from the sensor 35. In other words, the user notices that the end processing of the examination currently being performed in the medical image diagnostic apparatus 14 is not executed by the alarm sound, and the user returns to the front of the medical image diagnostic apparatus 14 to return from the sensor 35. It is determined whether or not the supply of the detection signal has been resumed.

  If it is determined in step S44 that the supply of the detection signal from the sensor 35 has not been resumed, the process waits until the supply of the detection signal from the sensor 35 is resumed.

  When it is determined in step S44 that the supply of the detection signal from the sensor 35 has been resumed, the control unit 31 performs the inspection end unprocessed alarm sound generation stop control for causing the alarm sound generation unit 65 to stop the generated alarm sound. A signal is generated and supplied to the alarm sound generator 65.

  In step S <b> 46, the alarm sound generation unit 65 stops the generation of the alarm sound based on the inspection end unprocessed alarm sound generation stop control signal supplied from the control unit 31. Thereafter, the process proceeds to step S32. In the processing of steps S44 to S46 in FIG. 13, the alarm sound is not generated until it is determined whether or not the supply of the detection signal from the sensor 35 is restarted when the user returns to the front of the medical image diagnostic apparatus 14. Since it is not stopped, the user notices that the examination end processing currently being performed in the medical image diagnostic apparatus 14 is not executed, and the alarm sound continues to be generated until the user returns to the front of the medical image diagnostic apparatus 14.

  When it is determined in step S41 that the supply of the detection signal from the sensor 35 is not stopped (that is, when it is determined that the user is in front of the medical image diagnostic apparatus 14), the process returns to step S32, and the step The process after 32 is repeated.

  In the inspection end process described with reference to the flowchart of FIG. 13, when it is determined in step S32 that the inspection end setting conditions set in advance are not satisfied, the processes in steps S41 to S46 are performed. Of course, if it is determined in step S32 that the inspection end setting condition set in advance is satisfied, the processing in steps S41 to S46 may be performed. As a result, when the user leaves the medical image diagnostic apparatus 14 before the examination end process is executed even though the examination is actually finished, the examination end process is still being executed. You can know that there is no.

  In the examination end process described with reference to the flowchart of FIG. 13, an alarm sound is generated even when the user is away from the medical image diagnostic apparatus 14 for a moment during the examination. There may be cases where the user feels troublesome. Therefore, whether or not to perform the processing of steps S41 to S46 may be set in advance according to the user's preference.

  Furthermore, before the processing of steps S41 to S46, a step is provided for determining whether or not the user has left the medical image diagnostic apparatus 14 for a predetermined time, and only when the user has left the medical image diagnostic apparatus 14 for a predetermined time. An alarm sound may be generated by performing the processing of S41 to S46. Thereby, it is possible to prevent the alarm sound from being generated when the user leaves the medical image diagnostic apparatus 14 for a moment during the examination and immediately returns to the front of the medical image diagnostic apparatus 14 thereafter.

  Instead of providing the alarm sound generating unit 65 in the main body 21 of the medical image diagnostic apparatus 14, a wireless key provided with an alarm sound generating unit for generating an alarm sound is always carried by the user in advance, so that When the user leaves the medical image diagnostic apparatus 14 before the end processing of the examination currently performed on the image diagnostic apparatus 14 is executed (that is, the user is in the medical image diagnostic apparatus 14 even though the examination is being performed). When the user is away from the medical image diagnostic apparatus 14 before the examination end process is executed even though the examination is actually finished). A warning sound provided in advance in the wireless key being used may be used to notify the user that the examination end processing has not been executed.

  FIG. 14 shows an internal configuration of the wireless key 66 carried by the user.

  As shown in FIG. 14, the wireless key 66 includes a wireless key control unit 71, a wireless key communication unit 72, a wireless key alarm sound generation unit 73, and a wireless key input unit 74.

  The wireless key control unit 71 includes a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), generates various control signals, and supplies them to the respective units to control the driving of the wireless key 66 as a whole.

  The wireless key communication unit 72 performs bidirectional communication with the medical image diagnostic apparatus 14 using an infrared signal or the like.

  Based on an instruction from the wireless key control unit 71, the wireless key alarm sound generation unit 73 generates and stops an alarm sound that notifies the user that the examination end processing has not been executed.

  The wireless key input unit 74 is provided at a predetermined position of the wireless key 66, and has an inspection end instruction button (not shown) for inputting an instruction to end the inspection. The instruction input by is supplied to the wireless key control unit 71.

  With reference to the flowchart of FIG. 15, another examination end process in the medical image diagnostic apparatus 14 of FIG. 12 when the user carries the wireless key 66 of FIG. 14 will be described. The processes in steps S51, S52, and S58 to S65 in FIG. 15 are the same as the processes in steps S11 to S20 in FIG.

  When it is determined in step S52 that the preset inspection end setting condition is not satisfied, the control unit 31 determines whether or not the supply of the detection signal from the sensor 35 is stopped in step S53. That is, the control unit 31 determines whether or not the supply of the detection signal indicating whether or not the user who examines the subject exists in front of the medical image diagnostic apparatus 14 is stopped from the sensor 35.

  When it is determined in step S53 that the supply of the detection signal from the sensor 35 is not stopped (that is, when it is determined that the user is in front of the medical image diagnostic apparatus 14), the process returns to step S52, and the step The process after 52 is repeated.

  When it is determined in step S53 that the supply of the detection signal from the sensor 35 is stopped (that is, when it is determined that the user has moved away from the front of the medical image diagnostic apparatus 14), the control unit 31 determines in step S54 that the user A wireless key alarm sound generation control signal for causing the wireless key alarm sound generation unit 73 of the wireless key 66 to be carried to generate an alarm sound is generated and supplied to the communication unit 36.

  In step S <b> 55, the communication unit 36 acquires the wireless key warning sound generation control signal supplied from the control unit 31, and transmits the acquired wireless ski warning sound generation control signal to the wireless key 66.

  Here, the wireless key alarm sound generation processing of the wireless key 66 in FIG. 14 corresponding to the processing in step S63 in FIG. 15 will be described with reference to the flowchart in FIG.

  In step S71, the wireless key control unit 71 determines whether or not the wireless key communication unit 72 has received the wireless key alarm sound generation control signal from the medical image diagnostic apparatus 14, and the wireless key alarm sound is received from the medical image diagnostic apparatus 14. Wait until the wireless key communication unit 72 determines that the generation control signal has been received.

  If it is determined in step S71 that the wireless key communication unit 72 has received the wireless key alarm sound generation control signal from the medical image diagnostic apparatus 14, the wireless key control unit 71 alerts the wireless key alarm sound generation unit 73 in step S72. A wireless key alarm sound generation start control signal for generating a sound is generated and supplied to the wireless key alarm sound generator 73.

  In step S <b> 73, the wireless key alarm sound generation unit 73 starts generating an alarm sound based on the wireless key alarm sound generation start control signal supplied from the wireless key control unit 71. Thus, the user can know that the examination end process currently being performed in the medical image diagnostic apparatus 14 is not executed.

  In step S <b> 74, the wireless key control unit 71 determines whether or not an instruction to end the inspection is given by the user operating an inspection end instruction button (not shown) of the wireless key input unit 74.

  If it is determined in step 74 that the user has instructed to end the inspection by operating an inspection end instruction button (not shown) of the wireless key input unit 74, the wireless key control unit 71 performs medical A test end instruction signal for instructing the diagnostic imaging apparatus 14 to execute the test end process is generated and supplied to the wireless key communication unit 72.

  In step S <b> 76, the wireless key communication unit 72 acquires the examination end instruction signal supplied from the wireless key control unit 71 and transmits the obtained examination end instruction signal to the medical image diagnostic apparatus 14.

  In step S <b> 77, the wireless key control unit 71 generates a wireless key alarm sound generation stop control signal for causing the wireless key alarm sound generation unit 73 to stop generating the alarm sound, and supplies the wireless key alarm sound generation unit 73 to the wireless key alarm sound generation unit 73. .

  In step S78, the wireless key alarm sound generation unit 73 stops the generation of the alarm sound based on the wireless key alarm sound generation stop control signal supplied from the wireless key control unit 71.

  If it is determined in step S74 that the user has not instructed to end the inspection by operating an inspection end instruction button (not shown) of the wireless key input unit 74, the wireless key control unit 71 in step S79. The user operates an alarm sound generation stop instruction button (not shown) of the wireless key input unit 74 to determine whether or not an instruction to stop the generation of the alarm sound has been made.

  If it is determined in step S79 that the user has issued an instruction to stop the generation of an alarm sound by operating an alarm sound generation stop instruction button (not shown) of the wireless key input unit 74, the process proceeds to step S77. Then, the processing after step S77 is performed. As a result, the user can stop the generation of the alarm sound of the wireless key 66, and after stopping the generation of the alarm sound of the wireless key 66, the user returns to the medical image diagnostic apparatus 14 to execute the examination end process. Can do. Therefore, it is possible to further improve the operability of the medical image diagnostic apparatus 14 in the examination end process.

  If it is determined in step S79 that the user has not issued an instruction to stop the generation of the alarm sound by operating an alarm sound generation stop instruction button (not shown) of the wireless key input unit 74, the process proceeds to step S74. Returning to step S74, the processes after step S74 are repeated. As a result, when the user operates an inspection end instruction button (not shown) or an alarm sound generation stop instruction button (not shown) of the wireless key input unit 74, an inspection end instruction or an alarm sound generation stop instruction is issued. Until the alarm is issued, the alarm sound of the wireless key 66 can be continuously generated.

  Returning to FIG. 15, in step S <b> 56, the control unit 31 determines whether the communication unit 36 has received the inspection end instruction signal from the wireless key 66, and the communication unit 36 has received the inspection end instruction signal from the wireless key 66. Wait until it is determined.

  If it is determined in step S56 that the communication unit 36 has received the inspection end instruction signal from the wireless key 66, the process proceeds to step S64, and the processes after step S64 are executed.

  In this way, by using an alarm sound provided in advance on the wireless key 66 carried by the user, the user is informed that the inspection end processing has not been executed, and the user presses the inspection end instruction button on the wireless key 66. Since the medical image diagnostic apparatus 14 is instructed to execute the examination end process by operating the, the medical use is performed when the user leaves the medical image diagnostic apparatus 14 despite the examination. Even if it is away from the image diagnostic apparatus 14, it is possible to instruct the medical image diagnostic apparatus 14 to execute the examination end process. Thereby, the operativity of the test | inspection completion | finish process in the medical image diagnostic apparatus 14 can further be improved.

  When it is determined in step S52 that the inspection end setting condition set in advance is satisfied, the control unit 31 determines in step S57 whether or not the supply of the detection signal from the sensor 35 is stopped. That is, the control unit 31 determines whether or not the supply of the detection signal indicating whether or not the user who examines the subject exists in front of the medical image diagnostic apparatus 14 is stopped from the sensor 35.

  When it is determined in step S57 that the supply of the detection signal from the sensor 35 is stopped (that is, when it is determined that the user has left the front of the medical image diagnostic apparatus 14), the process proceeds to step S54, and then the step The processing after S54 is executed.

  Thus, when the user leaves the medical image diagnostic apparatus 14 before the examination end process is executed even though the examination is actually finished, the user is currently performed in the medical image diagnostic apparatus 14.
