And have.

  The examination information DB 121 stores examination information indicating an examination scheduled to be performed by the medical image diagnostic apparatus 100. Here, the examination information DB 12a described with reference to FIG. 4 stores examination schedules of all the medical image diagnostic apparatuses 100a to 100c in the power management system 1, whereas the examination information included in each medical image diagnostic apparatus 100. The DB 121 stores only the inspection schedule of its own device. The data structure stored in the inspection information DB 121 is the same as the data structure of the inspection information DB 12a shown in FIG.

  The used power DB 122 stores information in which the amount of power to be used is associated with each function of the medical image diagnostic apparatus 100. In other words, the used power DB 122 stores information in which the power consumption is associated with each function used by the medical image diagnostic apparatus 100 in the examination. FIG. 9 is a diagram illustrating an example of a data structure stored in the used power DB 122 according to the first embodiment. As illustrated in FIG. 9, the power usage DB 122 stores information in which “diagnosis region”, “major function classification”, “small function classification”, and “power consumption” are associated with each other. In the present embodiment, an ultrasonic diagnostic apparatus will be described as an example of the medical image diagnostic apparatus 100.

  Here, the “diagnostic part” stored in the used power DB 122 indicates the part of the subject to be examined. For example, “abdomen”, “circulatory organ”, and the like are stored in “diagnosis region”. The “major function classification” stored in the used power DB 122 is a classification of the functions of the medical image diagnostic apparatus 100, and here indicates an imaging mode. For example, “B mode”, “color Doppler mode”, and the like are stored in “major function classification”.

  Further, the “small function classification” stored in the power consumption DB 122 is a further classified function among the functions of the medical image diagnostic apparatus 100, and here, shows various functions that can be selected during image processing. . For example, “fine image processing”, “noise reduction processing”, and the like are stored in the “function small classification”. The “power consumption” stored in the used power DB 122 indicates the amount of power consumed when executing a function that is sub-classified among the functions of the medical image diagnostic apparatus 100. For example, “150 W”, “120 W”, and the like are stored in “power consumption”.

  As an example, the power usage DB 122 shown in FIG. 9 indicates that the power consumed when the abdomen is imaged in the B mode and the captured medical image data is subjected to fine image processing is 150 W. The power consumption DB 122 shown in FIG. 9 indicates that the power consumed when the abdomen is imaged in the B mode and the captured medical image data is subjected to noise reduction processing is 120 W.

  Note that “fine image processing” is image filter calculation processing, in which structural analysis is performed on an ultrasound image, and a smoothing filter that differs depending on the structure is applied to each location to maintain the sharpness of the image. It corresponds to the process of reducing noise. In addition, “noise reduction processing” is transmission / reception of a transmission / reception unit. Usually, one ultrasonic image is created by one transmission / reception, and reception is obtained by transmitting / receiving ultrasonic waves multiple times from a plurality of different directions. It corresponds to the process of reducing noise by synthesizing signals to create one ultrasonic image. As described above, since the functions used are different between the “fine image processing” and the “noise reduction processing”, the amount of power used is also different.

  The activation control unit 123 transmits an activation request to the power management apparatus 10 in response to an activation request from the operator of the medical image diagnostic apparatus 100. Further, the activation control unit 123 controls activation of the medical image diagnostic apparatus 100 according to the determination result of the power management apparatus 10. Here, the activation control unit 123 causes the first specifying unit 124 and the second specifying unit 125 to execute the use power suppression process when the power management apparatus 10 is notified of suppression of the used power amount.

  In addition, the activation control unit 123 turns off the power of the medical image diagnostic apparatus 100 according to an instruction from the power management apparatus 10 after the examination by the medical image diagnostic apparatus 100 is completed. Thereby, it becomes possible to prepare for the power supply used for the next test | inspection by the other diagnostic imaging apparatus 100. FIG.

For example, the second specifying unit 125 includes at least a function specified as a function to be used in a test scheduled to be executed when the maximum amount of power is not within the range of power that can be supplied, and can be supplied. Identify functions that can be activated by volume.

  More specifically, the second specifying unit 125 subtracts the amount of power used by a function not used in the examination from the maximum amount of power used in the medical image diagnostic apparatus 100 until the amount of power that can be supplied is reached. To do. Thereby, the 2nd specific | specification part 125 specifies the function which can be started with the electric energy which can be supplied including the function specified as a function used by the test | inspection scheduled to be performed at least.

  For example, the second identifying unit 125 refers to the power consumption DB 122 and identifies the combination of “diagnostic part”, “major function classification”, and “minor function classification” as a function that is not used in an examination scheduled to be performed. Identify what matches the combination. Then, the second specifying unit 125 uses the “power consumption” associated with the combination of the specified “diagnostic part”, “major functional classification”, and “small functional classification” for the function that does not use the power consumption in the inspection. As specified. Here, the 2nd specific | specification part 125 subtracts in order from the electric energy which a high load application function uses among the functions which are not used in a test | inspection, for example.

  For example, in the case where the diagnostic part is “abdominal part” and imaging is performed in “color Doppler mode”, the second specifying unit 125 has “diagnostic part” as “abdominal part” and the functional classification is “color Doppler mode”. The function with the highest power consumption other than the function is specified as the stop function. More specifically, the second specifying unit 125 refers to the power usage DB 122 illustrated in FIG. 9, “diagnosis region” is “abdomen”, “major function classification” is “B mode”, A function whose “function sub-classification” is “fine image processing” is specified as a stop function.

  Then, the second specifying unit 125 determines whether the power amount value obtained by subtracting the specified power consumption amount from the maximum power amount used by the medical image diagnostic apparatus 100 is within the range of the power amount that can be supplied. Determine whether. Here, when the value of the subtracted power amount is not within the range of the power amount that can be supplied, the second specifying unit 125 further specifies the power consumption amount of the function that is not used in the examination, and the medical image diagnostic apparatus 100 is subtracted from the amount of power used. More specifically, the second specifying unit 125 refers to the power usage DB 122 illustrated in FIG. 9, “diagnosis region” is “abdomen”, “major function classification” is “B mode”, A function whose “small function classification” is “noise reduction” is specified as a stop function.

  In addition, as functions unnecessary for the inspection of the diagnostic imaging apparatus 100, for example, a high-load function (a function with a high power consumption load) for the central control apparatus 104, a function for controlling software unnecessary for the inspection, and a printing process are unnecessary. Includes a function for controlling energization of the connected printer and a function for controlling energization of the drive when recording on an optical medium is unnecessary.

  The function control unit 126 restricts the use of functions other than the specified startable function. For example, the function control unit 126 supplies power only to functions that can be used from the amount of power supplied to the medical image diagnostic apparatus 100 by controlling the power supply unit 109 based on the identification result of the second identification unit 125. To do. The function control unit 126 controls the central control device 104 so as not to activate a function for controlling software unnecessary for the inspection.

FIG. 10 is a flowchart illustrating a processing procedure performed by the medical image diagnostic apparatus 100 according to the first embodiment. As illustrated in FIG. 10, the activation control unit 123 determines whether an activation request has been received from the operator (step S101).

  Here, when the activation control unit 123 determines that the activation request is received from the operator (Yes in Step S101), the activation control unit 123 transmits the activation request to the power management apparatus 10 (Step S102). If the activation control unit 123 does not determine that an activation request has been received from the operator (No in step S101), the activation control unit 123 repeatedly determines whether an activation request has been received from the operator.

  Subsequently, the activation control unit 123 receives a response to the activation request from the power management apparatus 10 (step S103). Then, the activation control unit 123 analyzes the response result and determines whether or not the suppression of the power consumption is notified (step S104). Here, when the activation control unit 123 does not determine that the suppression of the power consumption is notified (No in Step S104), the activation control unit 123 proceeds to Step S109.

  On the other hand, when the activation control unit 123 determines that the suppression of the power consumption is notified (Yes in step S104), the medical image diagnostic apparatus 100 executes the power consumption suppression process (step S105). Note that the procedure of the power consumption suppression process will be described later with reference to FIG.

  And the starting control part 123 responds to the power management apparatus 10 with the result of the electric power consumption suppression process (step S106). Further, the activation control unit 123 determines whether or not the medical image diagnostic apparatus 100 can be activated (step S107). Here, if the activation control unit 123 does not determine that the medical image diagnostic apparatus 100 can be activated (No in step S107), the process ends. On the other hand, when the activation control unit 123 determines that the medical image diagnostic apparatus 100 can be activated (step S107, Yes), the function control unit 126 restricts the function to be used (step S108).

  Subsequently, the activation control unit 123 determines whether an activation instruction has been received from the power management apparatus 10 (step S109). Here, if the activation control unit 123 determines that an activation instruction has been received from the power management apparatus 10 (Yes in step S109), the activation control unit 123 instructs the central control apparatus 104 to execute the function (step S110). If the activation control unit 123 does not determine that the activation instruction has been received from the power management apparatus 10 (No in step S109), the activation control unit 123 repeatedly determines whether the activation instruction has been received from the power management apparatus 10.

  Then, when the inspection by the operation of the operator starts, the activation control unit 123 determines whether or not the inspection is finished (Step S111). If the activation control unit 123 determines that the inspection has been completed (step S111, Yes), the activation control unit 123 notifies the power management apparatus 10 of the completion of the inspection (step S112). Note that if the activation control unit 123 does not determine that the inspection has ended (No in step S111), the activation control unit 123 repeatedly determines whether the inspection has ended.

  Then, the activation control unit 123 determines whether or not an instruction to turn off the power has been given (step S113). If the activation control unit 123 determines that an instruction to turn off the power has been given (step S113, Yes), the power-off process ends. On the other hand, if it is not determined that the power-off instruction has been given (No at Step S113), the activation control unit 123 repeatedly determines whether or not the power-off instruction has been issued.

  FIG. 11 is a flowchart illustrating a processing procedure of power consumption suppression processing by the medical image diagnostic apparatus 100 according to the first embodiment. As illustrated in FIG. 11, the first specifying unit 124 specifies a function used in the inspection and a function not used in the inspection (Step S <b> 201). And the 2nd specific | specification part 125 determines whether all the functions which are not used by a test | inspection are stopped (step S202).

  If the second specifying unit 125 does not determine that all the functions that are not used in the inspection are stopped (No in step S202), the second specifying unit 125 specifies a function having a high power load among the functions that are not used in the inspection as the stop function. (Step S203). Moreover, the 2nd specific | specification part 125 calculates the electric energy after suppressing starting of a stop function (step S204). And the 2nd specific | specification part 125 determines whether the electric energy after suppression of starting of a stop function is in the range of the electric energy which can be supplied (step S205).

  Here, when the second specifying unit 125 determines that the amount of power after suppressing the activation of the stop function is within the range of the amount of power that can be supplied (Yes in step S205), the second specifying unit 125 activates the medical image diagnostic apparatus 100. It is determined that it is possible (step S206). On the other hand, if the second specifying unit 125 does not determine that the amount of power after suppressing the activation of the stop function is within the range of power that can be supplied (step S205, No), the process proceeds to step S202. Repeat the process to specify the stop function.

  If the second specifying unit 125 determines that all functions not used in the examination are stopped (step S202, Yes), the second specifying unit 125 determines that the medical image diagnostic apparatus 100 cannot be started (step S207). .

  FIG. 12 is a flowchart illustrating a processing procedure performed by the power management apparatus 10 according to the first embodiment. As illustrated in FIG. 12, the activation control unit 13a determines whether an activation request has been received from the medical image diagnostic apparatus 100 (step S301). Here, when the activation control unit 13a determines that the activation request is received from the medical image diagnostic apparatus 100 (Yes in Step S301), the power usage amount specifying unit 13b acquires the examination information from the examination information DB 12a (Step S302). ). If the activation control unit 13a does not determine that an activation request has been received from the medical image diagnostic apparatus 100 (No in step S301), the activation control unit 13a repeatedly determines whether an activation request has been received from the medical image diagnostic apparatus 100.

  Then, the used power amount specifying unit 13b specifies the medical image diagnostic apparatus 100 used for the examination (step S303), and specifies the power amount scheduled to be used by the specified medical image diagnostic apparatus 100 (step S304). Further, the used power amount specifying unit 13b acquires the power amount that can be supplied (step S305).

  Then, the power usage amount specifying unit 13b determines whether or not the medical image diagnostic apparatus 100 can be used (step S306). Here, when the power usage amount specifying unit 13b determines that the medical image diagnostic apparatus 100 is usable (Yes in Step S306), the activation control unit 13a instructs the medical image diagnostic apparatus 100 to start (Step S306). S307).

  Subsequently, the activation control unit 13a determines whether or not an inspection end notification has been received (step S308). Here, if the activation control unit 13a determines that the notification of the completion of the examination has been received (step S308, Yes), the activation control unit 13a instructs the medical image diagnostic apparatus 100 to turn off the power (step S309). If the activation control unit 13a does not determine that the notification of the completion of the inspection has been received (No at Step S308), the activation control unit 13a repeatedly executes the process at Step S308. Then, the activation control unit 13a determines whether all the inspections have been completed (Step S310). Here, if the activation control unit 13a determines that all the inspections have been completed (step S310, Yes), the process ends. On the other hand, if the activation control unit 13a does not determine that all the inspections have been completed (No at Step S310), the process proceeds to Step S302. That is, the power usage amount specifying unit 13b acquires inspection information from the inspection information DB 12a.

  On the other hand, when the power usage amount specifying unit 13b does not determine that the medical image diagnostic apparatus 100 is usable (No in step S306), the activation control unit 13a controls the medical image diagnostic apparatus 100 to suppress the power consumption. (Step S311). Then, the activation control unit 13a receives the result of the power consumption suppression process from the medical image diagnostic apparatus 100 (step S312).

  Subsequently, the activation control unit 13a determines whether or not the medical image diagnostic apparatus 100 can be activated (step S313). Here, if the activation control unit 13a determines that the medical image diagnostic apparatus 100 can be activated (step S313, Yes), the activation control unit 13a instructs the medical image diagnostic apparatus 100 to activate (step S307). On the other hand, if the activation control unit 13a does not determine that the medical image diagnostic apparatus 100 can be activated (No in step S313), the process ends.

  As described above, in the first embodiment, when the amount of power used by the desired medical image diagnostic apparatus 100 is not within the range of the amount of power that can be supplied by the power management system 1 operating in the energy saving mode, A function that the diagnostic imaging apparatus 100 does not use in the examination is specified, and activation of this function is restricted. Accordingly, the operator can perform an examination using the desired medical image diagnostic apparatus 100 without grasping the power amount of all the medical image diagnostic apparatuses 100. As a result, according to the first embodiment, when the power management system 1 is operated in the energy saving mode, the load of power management can be reduced.

  In the above-described embodiment, the second specifying unit 125 specifies a power consumption amount of a function that is not used in the inspection by a combination of “diagnosis region”, “major function classification”, and “small function classification”. Although described, the embodiment is not limited to this. For example, the second specifying unit 125 may specify all functions other than the combination of “diagnosis site” and “major function classification” as stop functions. More specifically, when the diagnostic site is “abdomen” and imaging is performed in “color Doppler mode”, the second specifying unit 125 refers to the power usage DB 122 shown in FIG. All functions that are “abdomen” and whose major function classification is “B mode” may be specified as the stop function.

  Further, for example, the second specifying unit 125 may specify all functions other than the “diagnostic part” as a stop function. More specifically, when the diagnostic part is “circulatory”, the second specifying unit 125 refers to the power usage DB 122 and stops all functions whose diagnostic part is other than “circulatory”.

  In addition, when the diagnostic part is “abdomen” and the imaging is performed in the B mode, the second identification unit 125 refers to the power consumption DB 122 and the diagnostic part is “abdomen” and the functional classification is “B”. Of the “small function classification” that is “mode”, the function having the highest “power consumption” may be specified as the stop function.

  Further, the second specifying unit 125 may estimate the function used in the examination from the past examination history statistics of the medical image diagnostic apparatus 100, for example, and may automatically suppress the function.

  Further, the medical image diagnostic apparatus 100 may supply only a minimum amount of power necessary for the examination. In such a case, for example, the second specifying unit 125 calculates the amount of power when all the functions specified as functions not used in the inspection are stopped. And the 2nd specific | specification part 125 determines whether the calculated electric energy is in the range of the electric energy which can be supplied. And the function control part 126 stops all the specified functions, when the calculated electric energy is in the range of the electric energy which can be supplied.

  In addition, the medical image diagnostic apparatus 100 displays information indicating that the energy saving mode has failed on the monitor 102 when the functions that are not used in the inspection are not within the range of the power supply that can be supplied even if they are stopped. It may be. In addition, the medical image diagnostic apparatus 100 calculates the calculated power amount when the calculated power amount is not within the range of the amount of power that can be supplied in the energy saving mode, but is within the range of the amount of power that can be originally supplied from the power supply facility 2. You may make it use electric energy. In such a case, the medical image diagnostic apparatus 100 displays on the monitor 102 information indicating that the energy saving mode has been canceled.

  Further, in the above-described embodiment, the activation control unit 123 has been described as being instructed to turn off the power after the inspection is finished and turning off its own power, but the embodiment is not limited thereto. For example, the activation control unit 123 may end the process without turning off the power after the inspection ends. In such a case, standby power is supplied to the medical image diagnostic apparatus 100.

  Further, in the above-described embodiment, when specifying the maximum value of the amount of power used by the medical image diagnostic apparatus 100, the medical image diagnostic apparatus 100 requested by the activation control unit 13a of the power management apparatus 10 to start from the examination information DB 12a. However, the embodiment is not limited to this. For example, the activation control unit 123 of the medical image diagnostic apparatus 100 may transmit an activation request including the apparatus ID of the medical image diagnostic apparatus 100 that transmits the activation request. In such a case, the activation control unit 13a of the power management apparatus 10 extracts the device ID included in the activation request, and obtains the usage power amount associated with the device ID that matches the extracted device ID from the maximum usage power amount DB 12c.

Further, the processing procedure from step S406 to step S411 shown in FIG. 14 is the same as the processing from step S108 to step S113 shown in FIG.

  As illustrated in FIG. 14, the activation control unit 123 that has received the response in step S403 analyzes the response result and determines whether the medical image diagnostic apparatus 200 can be activated (step S404). If the activation control unit 123 determines that the medical image diagnostic apparatus 200 can be activated (Yes in step S404), the activation control unit 123 determines whether or not the suppression of the power consumption is notified (step S405).

  If the activation control unit 123 does not determine that the suppression of the power consumption has been notified (No at Step S405), the activation control unit 123 proceeds to Step S407. On the other hand, when the activation control unit 123 determines that the suppression of the power consumption is notified (Yes in step S405), the function control unit 126 restricts the function to be used (step S406). If the activation control unit 123 does not determine that the medical image diagnostic apparatus 200 can be activated (No in step S404), the process ends.

As shown in FIG. 16, the power management system 1b according to the third embodiment includes a power supply facility 2, a medical image diagnostic apparatus 300a, a medical image diagnostic apparatus 300b, and a medical image diagnostic apparatus 300c. In the case where the medical image diagnostic apparatus 300a, the medical image diagnostic apparatus 300b, and the medical image diagnostic apparatus 300c are not distinguished, they are described as the medical image diagnostic apparatus 300. In addition, below, the same code | symbol is provided about the structure similar to the power management system 1 (1a) which concerns on embodiment mentioned above, and detailed description is abbreviate | omitted. The power management system 1b is assumed to be operated in the energy saving mode as in the first and second embodiments. The number of medical image diagnostic apparatuses 300 included in the power management system 1b is not limited to three.

  The configuration of the medical image diagnostic apparatus 300 according to the third embodiment is the same as the configuration of the medical image diagnostic apparatus 100 according to the first embodiment except for the configuration of the power management unit 320. For this reason, in FIG. 16, only the power amount management unit 320 of the medical image diagnostic apparatus 300 is illustrated. Although not shown in FIG. 16, the medical image diagnostic apparatus 300 includes a smart meter as the electric energy measuring device 108. This smart meter is a power meter with a communication function. Such a smart meter is connected to a distribution board or the like of the medical image diagnostic apparatus 300. For example, the smart meter measures the electric power used by the medical image diagnostic apparatus 300 every certain period, for example, every 5 minutes.

  Next, the configuration of the power management unit 320 included in the medical image diagnostic apparatus 300 according to the third embodiment will be described. As illustrated in FIG. 16, the power management unit 320 according to the third embodiment includes an inspection information DB 321, a suppliable power DB 322, a maximum usable power amount DB 323, a used power DB 122, a setting reception unit 324, and activation.

  The inspection information DB 321 stores inspection information indicating an execution schedule of an inspection scheduled in the power management system 1b. The data structure stored in the inspection information DB 321 is the same as the data structure of the inspection information DB 12a described with reference to FIG.

  The suppliable power DB 322 stores information indicating the amount of power that can be supplied from the power supply facility 2. The data structure stored in the suppliable power DB 322 is the same as the data structure of the suppliable power DB 12b described with reference to FIG.

  The maximum power consumption DB 323 stores information indicating the maximum power amount used by each medical image diagnostic apparatus 300 in the power management system 1b. The data structure stored in the maximum power consumption DB 323 is the same as the data structure of the maximum power consumption DB 12c described with reference to FIG.

  The setting reception unit 324 receives the setting of the upper limit value of the amount of power that can be supplied from the power supply facility 2. In addition, when the setting reception part 324 receives the setting of the upper limit of the electric energy which can be supplied, it will be referred to as "the energy saving mode function" being set effectively. In other words, when the energy saving mode function is set to be effective, the medical image diagnostic apparatus 300 receives the supply of the electric energy within the predetermined upper limit value from the power supply facility 2 and starts up. Note that in the power management system 1b according to the third embodiment, the medical image diagnostic apparatuses 300a to 300c will be described assuming that the energy saving mode function is set to be effective.

  The power consumption specifying unit 325 determines whether or not the medical image diagnostic apparatus 300 that has requested activation is to suppress the power consumption. Note that the function of the used power amount specifying unit 325 is the same as the function of the used power amount specifying unit 13b of the power management apparatus 10 according to the first embodiment.

Request to diagnostic device 300.

  Here, a case will be described in which the amount of power used in the function used in the examination performed by the medical image diagnostic apparatus 300a is not within the range of power that can be supplied and the medical image diagnostic apparatus 300b is being activated. For example, if the activation control unit 123 does not determine that the medical image diagnostic apparatus 300a can be activated based on the result of the power consumption suppression process, the request unit 327 activates another medical image diagnostic apparatus 300. It is determined whether or not. More specifically, the request unit 327 specifies a test being executed from the “test ID” of the suppliable power DB 322. Then, the request unit 327 refers to the inspection information DB 321 and specifies a device ID that matches the specified inspection ID. Here, the request unit 327 determines that another medical image diagnostic apparatus 300 is activated when the apparatus ID can be specified.

  For example, when the request unit 327 determines that the medical image diagnostic apparatus 300b is activated, the request unit 327 notifies the medical image diagnostic apparatus 300b of suppression of the power consumption. Here, the request unit 327 notifies the other specified medical image diagnostic apparatus 300b of information indicating the amount of power that is insufficient to activate the medical image diagnostic apparatus 300a.

  When the other medical image diagnostic apparatus 300 requested to suppress the power consumption by the request unit 327 is not capable of suppressing the power consumption, the notification unit 328 displays the scheduled end time of the examination by the other medical image diagnostic apparatus 300. Inform. Here, a case where the medical image diagnostic apparatus 300a requests the medical image diagnostic apparatus 300b to suppress power consumption will be described. For example, the notifying unit 328 of the medical image diagnostic apparatus 300a refers to the “examination date” associated with the “apparatus ID” of the medical image diagnostic apparatus 300b in the examination information DB 321 and estimates the scheduled end time of the examination. And the alerting | reporting part 328 displays the scheduled completion | finish time of the test | inspection by the other medical image diagnostic apparatus 300b on the monitor 102 of the medical image diagnostic apparatus 300a.

Also, the processing procedure from step S615 to step S616 shown in FIG. 17 is the same as the processing from step S408 to step S409 shown in FIG. Note that the procedure of the power consumption suppression process in step S607 is the same as the procedure of the power consumption suppression process described with reference to FIG.

  As illustrated in FIG. 17, when the activation control unit 123 does not determine in step S608 that the medical image diagnostic apparatus 300 can be activated based on the result of the power consumption suppression process (No in step S608). The request unit 327 determines whether another medical image diagnostic apparatus 300 is activated (step S609).

  Here, when the request unit 327 does not determine that the other medical image diagnostic apparatus 300 is activated (No in step S609), the process ends. On the other hand, when the request unit 327 determines that the other medical image diagnostic apparatus 300 is activated (Yes in step S609), the request unit 327 notifies the other medical image diagnostic apparatus 300 of suppression of the power consumption (step S610). .

  Subsequently, the request unit 327 receives the response result (step S611), and determines whether the other medical image diagnostic apparatus 300 can suppress the power consumption (step S612). Here, when the request unit 327 does not determine that the other medical image diagnostic apparatus 300 is capable of suppressing the power consumption (No in step S612), the notification unit 328 uses the other medical image diagnostic apparatus 300. The scheduled end time of the inspection is notified (step S613), and the process ends. On the other hand, when the request unit 327 determines that the other medical image diagnostic apparatus 300 can suppress the power consumption (Yes in step S612), the medical image diagnostic apparatus 300 proceeds to step S606. That is, the power usage amount specifying unit 325 determines whether or not the medical image diagnostic apparatus 300 can be used (step S606). When the power usage amount specifying unit 325 determines that the medical image diagnostic apparatus 300 can be used (step S606, Yes), the activation control unit 123 instructs the central control device 104 to execute the function (step). S615).

  On the other hand, when the activation control unit 123 determines in step S608 that the medical image diagnostic apparatus 300 can be activated based on the result of the power consumption suppression process (step S608, Yes), the function control unit 126 The function to be used is limited (step S614). Subsequently, the activation control unit 123 instructs the central control device 104 to execute the function (step S615).

  In step S616, when the activation control unit 123 accepts the end of the inspection (step S616, Yes), the activation control unit 123 determines whether all the inspections are completed (step S617). Here, if the activation control unit 123 determines that all the examinations have been completed (step S617, Yes), the power to the medical image diagnostic apparatus 300 is turned off (step S618), and the process ends. On the other hand, if the activation control unit 123 does not determine that all the inspections have been completed (No in step S617), the power usage amount specifying unit 325 proceeds to step S602, and acquires inspection information from the inspection information DB 321.

  FIG. 18 is a flowchart illustrating a processing procedure performed by another medical image diagnostic apparatus 300 according to the third embodiment. The other medical image diagnostic apparatus 300 executes the following processing after the examination is started until the examination is finished. As illustrated in FIG. 18, the activation control unit 123 of the other medical image diagnostic apparatus 300 determines whether or not the requesting medical image diagnostic apparatus 300 is notified of the suppression of power consumption (step S <b> 701).

  Here, when the activation control unit 123 of the other medical image diagnostic apparatus 300 determines that the suppression of the power consumption has been notified (Yes in step S701), the other medical image diagnostic apparatus 300 performs the power consumption suppression process. (Step S702). Here, the other medical image diagnostic apparatus 300 executes processing so as to suppress the insufficient power amount notified from the requesting medical image diagnostic apparatus 300. Note that details of step S702 are the same as the processing procedure of the power consumption suppression processing illustrated in FIG.

  Then, the activation control unit 123 of the other medical image diagnostic apparatus 300 responds with the result of the power consumption suppression process (step S703) and ends the process. If the activation control unit 123 of the other medical image diagnostic apparatus 300 does not determine that the power consumption is notified (No in step S701), the activation control unit 123 repeatedly determines whether the power consumption is notified. .

  As described above, in the third embodiment, when the amount of power used by the desired medical image diagnostic apparatus 300 is not within the range of power that can be supplied by the power management system 1b operated in the energy saving mode, A function that is not used in the examination by the diagnostic imaging apparatus 300 is specified, and activation of this function is restricted. Accordingly, the operator can perform an examination using the desired medical image diagnostic apparatus 300 without knowing the amount of power of all the medical image diagnostic apparatuses 300. As a result, according to the third embodiment, it is possible to reduce the load of power management when operating the power management system 1b in the energy saving mode.

  Furthermore, if the medical image diagnostic apparatus 300 according to the third embodiment does not determine that it can be activated based on the result of the power consumption suppression process, the other medical image diagnostic apparatus 300 that is activated Request the power consumption suppression process. Accordingly, when a function that is not used in the examination is activated in another medical image diagnostic apparatus 300 that is being activated, this function can be stopped and the medical image diagnostic apparatus 300 can be activated. As described above, according to the medical image diagnostic apparatus 300 according to the third embodiment, power is interchanged between the medical image diagnostic apparatuses 300. As described above, in the third embodiment, since the power in the power management system 1b is used more effectively, a plurality of medical image diagnostic apparatuses 300 used for examination can be used as much as possible.

  In the third embodiment, the power management system 1b can be configured without a power management device. Thereby, the operator of the power management system 1b can reduce the initial cost when constructing the power management system 1b.

(Other embodiments)
In the above-described third embodiment, the amount of power used in the function used in the examination by the medical image diagnostic apparatus 300 is not within the range of power that can be supplied, and another medical image diagnostic apparatus 300 is activated. In the case where it is in the middle, a case has been described in which another medical image diagnostic apparatus is requested to perform power consumption suppression processing. Requesting such a power consumption suppression process to another active medical image diagnostic apparatus is also applicable to the first embodiment and the second embodiment.

  For example, the medical image diagnostic apparatus 100a according to the first embodiment allows the power management apparatus 10 to accommodate the amount of power that is insufficient when the power management apparatus 10a is not within the range of power that can be supplied even after performing the power consumption suppression process. Request. Then, the power management apparatus 10 determines whether another medical image diagnostic apparatus 100 is activated. Here, when the power management apparatus 10 determines that the medical image diagnostic apparatus 100b is activated, the power management apparatus 10 notifies the medical image diagnostic apparatus 100b of suppression of the power consumption. Subsequently, when the power amount deficient from the other medical image diagnostic apparatus 100b is accommodated, the power management apparatus 10 notifies the medical image diagnostic apparatus 100a that the deficient power amount has been accommodated. Then, the power consumption suppression process is executed again.

  Further, for example, when the power management apparatus 20 according to the second embodiment performs the power consumption suppression process, the power amount used by the medical image diagnostic apparatus 200a is not within the range of power that can be supplied. It is determined whether another medical image diagnostic apparatus 200 is activated. Here, when the power management apparatus 20 determines that the other medical image diagnostic apparatus 200b is activated, the power management apparatus 20 notifies the medical image diagnostic apparatus 200b of suppression of the power consumption. The power management apparatus 20 executes the power consumption suppression process again for the medical image diagnostic apparatus 200a when the insufficient power amount is accommodated from the medical image diagnostic apparatus 200b.

  In the first to third embodiments described above, the power management system 1 (1a, 1b) has been described as operating in the energy saving mode. However, the embodiment is not limited to this. Absent. For example, in the first embodiment and the second embodiment, the power management apparatus 10 (20) sets an upper limit value of the amount of power that can be supplied that is lower than the maximum value of power that can be supplied by the power supply facility 2. Explained as a thing. However, in the first embodiment and the second embodiment, the energy saving mode may be set for each medical image diagnostic apparatus 100 (200) in the power management system. For example, the power management apparatus 10 (20) does not set the upper limit value of the power management system 1 (1a) itself, and supplies power up to the maximum amount of power that can be supplied from the power supply facility 2. The medical image diagnostic apparatus 100 (200) set to the energy saving mode individually sets the upper limit value of the usable electric energy, and receives power supply within the range of the upper limit value. In such a case, the power management apparatus 10 (20) associates with the “apparatus ID” for each medical image diagnostic apparatus 100 (200) and sets the upper limit value of the power consumption to be used as “utilization power consumption” and the maximum utilization power consumption DB 12c. To remember. Even when the power management system 1 (1a, 1b) is operated in the energy saving mode, the upper limit value of the amount of power that can be used for each medical image diagnostic apparatus 100 (200, 300) is individually set. The power supply may be received within the range of the upper limit value.

  Moreover, although embodiment mentioned above demonstrated the case where it operate | moves by energy saving mode, embodiment is not limited to this. For example, the present invention can also be applied when there is an emergency in which the power supplied during a disaster is limited compared to normal times. More specifically, in the first embodiment and the second embodiment, the power management apparatus 10 (20) performs medical use based on the amount of power that the power supply facility 2 can supply without setting an upper limit value. Power is supplied to the diagnostic imaging apparatus 100 (200). In such a case, the power management apparatus 10 (20) may activate the function used for the inspection within the range of the amount of power supplied from the power supply facility 2. For example, the power management apparatus 10 (20) restricts the function of the medical image diagnostic apparatus 100 (200) so that only the minimum amount of power necessary for the examination is supplied to the medical image diagnostic apparatus 100 (200). Similarly, in the third embodiment, each medical image diagnostic apparatus 300 limits the function so that only the minimum amount of power required for the examination is supplied. Thereby, it is possible to save the trouble of operating after grasping the electric energy of all the medical image diagnostic apparatuses, and to prevent the desired medical image diagnostic apparatus from being used and hindering the examination and diagnosis itself. In addition, a plurality of medical image diagnostic apparatuses used for examination can be used as much as possible.

  Further, the processing by the medical image diagnostic apparatus described in the above-described embodiment can be realized by executing a program prepared in advance by a computer included in the medical image diagnostic apparatus. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.

  According to at least one embodiment described above, it is possible to reduce the load of power management.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
