Description

  Embodiments described herein relate generally to a management system and a medical image diagnostic apparatus.

  Conventionally, a method of managing the power mode of an X-ray CT (Computed Tomography) apparatus using examination reservation information has been proposed. An X-ray CT apparatus that executes this management method acquires examination reservation information from, for example, a radiology information system (RIS) or a hospital information system (HIS). Then, the X-ray CT apparatus shifts to a power saving mode in a time zone when there is no inspection, and shifts to an operation mode in which an X-ray CT image can be taken from a time that goes back from the inspection reservation time.

  Here, when operating a medical image diagnostic apparatus installed in a hospital, it is necessary to cope not only with an examination according to a reservation but also an emergency examination. However, the above management method can cope with the examination according to the appointment, but cannot deal with the emergency examination immediately. In addition, some medical image diagnostic apparatuses installed in hospitals take time to start up, and for emergency response, it is necessary to perform appropriate operations according to the start-up time.

Reconfigure (volume data).

  Here, a configuration example of an X-ray CT apparatus installed in the management system 1 as the medical image diagnostic apparatus 30-1 will be described with reference to FIG. FIG. 2 is a diagram for explaining a configuration example of an X-ray CT apparatus installed in the management system shown in FIG. 1 as a medical image diagnostic apparatus. As shown in FIG. 2, the X-ray CT apparatus as the medical image diagnostic apparatus 30-1 includes a gantry device 310, a couch device 320, a console device 330, and a power supply unit 340.

  The gantry device 310 is a device that irradiates the subject P with X-rays and collects projection data from X-ray detection data transmitted through the subject P, and includes an X-ray irradiation control unit 311, an X-ray generation device 312, and the like. , A detector 313, a collecting unit 314, a rotating frame 315, a gantry driving unit 316, and a detector control unit 317.

  The rotating frame 315 supports an X-ray generator 312 having an X-ray tube 312a (described later) and a detector 313 so as to be rotatable around the subject P. The rotating frame 315 supports the X-ray generator 312 and the detector 313 so as to face each other with the subject P interposed therebetween, and is rotated in a circular orbit around the subject P by a gantry driving unit 316 described later.

  The X-ray tube 312a emits X-rays. Specifically, the X-ray tube 312a is a vacuum tube that generates an X-ray beam on the subject P by a high voltage supplied by an X-ray irradiation control unit 311 described later. The X-ray tube 312 a exposes the X-ray beam to the subject P as the rotating frame 315 rotates. The X-ray tube 312a generates an X-ray beam that spreads with a fan angle and a cone angle.

The X-ray irradiation control unit 311 adjusts the X-ray irradiation range (fan angle and cone angle) by adjusting the aperture of the collimator 312c.

  Here, the X-ray tube 312a has a cathode filament and an anode target. When the cathode filament is heated to a predetermined temperature by the filament current supplied from the X-ray irradiation control unit 311, electrons can be emitted. Electrons emitted from the cathode filament collide with the anode target at a speed corresponding to the voltage applied between the cathode filament and the anode target. Thereby, the X-ray tube 312a generates X-rays. Moreover, the temperature of an anode target rises because an electron collides. For this reason, the X-ray tube 312a is provided with a cooling device (not shown) for preventing a failure due to an overload of heat accumulated by the generation of X-rays. The X-ray irradiation control unit 311 controls the temperature of the X-ray tube 312a by controlling the temperature of the cathode filament by the filament current and controlling the cooling by the cooling device.

Are arranged in multiple columns.

  Here, the X-ray sensitivity of the detection elements constituting the detector 313 changes depending on the temperature. For this reason, a heater (not shown) is connected to the detector 313, and this heater heats the detector 313 to a lower limit temperature for keeping the X-ray sensitivity of each detection element in a certain range. . This heater performs heating so as not to exceed the upper limit temperature in order to prevent failure of the detector 313. A detector control unit 317 shown in FIG. 2 controls the temperature of the detector 313 by controlling a heater connected to the detector 313.

  The collection unit 314 is a data acquisition system (DAS), collects X-ray detection data detected by the detector 313, and generates projection data. For example, the collection unit 314 generates projection data by performing amplification processing, A / D conversion processing, or the like on the X-ray intensity distribution data detected by the detector 313, and the generated projection data is a console device described later. 330.

The projection data collection process in the gantry device 310 is controlled.

  The preprocessing unit 334 performs correction processing such as inter-channel sensitivity correction processing, logarithmic conversion processing, offset correction, sensitivity correction, and beam hardening correction on the projection data generated by the collection unit 314. Then, corrected projection data is generated. Hereinafter, the corrected projection data generated by the preprocessing unit 334 is referred to as reconstruction projection data.

  The projection data storage unit 335 stores the reconstruction projection data generated by the preprocessing unit 334. The image reconstruction unit 336 reconstructs X-ray CT image data using the reconstruction projection data stored in the projection data storage unit 335. As the reconstruction method, there are various methods, for example, back projection processing. Further, as the back projection process, for example, a back projection process by an FBP (Filtered Back Projection) method can be cited. Alternatively, the image reconstruction unit 336 may reconstruct the X-ray CT image data using a successive approximation method.

  The control unit 338 controls the X-ray CT apparatus as a whole by controlling the operations of the gantry device 310, the couch device 320, and the console device 330. Specifically, the control unit 338 controls the scan performed by the gantry device 310 by controlling the scan control unit 333. Further, the control unit 338 controls the image reconstruction processing in the console device 330 by controlling the preprocessing unit 334 and the image reconstruction unit 336.

The server 10 can acquire the examination reservation information registered using the client terminal 20 via the in-hospital network 2. Therefore, the server 10 according to the first embodiment has a function of collectively managing the power mode of each medical image diagnostic apparatus 30 shown in FIG. 1 based on examination reservation information.

  The server 10 according to the first embodiment is configured as shown in FIG. 3 in order to manage the power mode. FIG. 3 is a diagram for explaining a configuration example of the server according to the first embodiment. In FIG. 3, only the components used by the server 10 to manage the power mode are shown as blocks, and the other components are not shown.

  As illustrated in FIG. 3, the server 10 according to the first embodiment includes a storage unit 10a, a management unit 10b, and a communication unit 10c. The communication unit 10 c is a NIC (Network Interface Card) or the like, and performs communication with other devices included in the management system 1 via the hospital network 2. The communication unit 10c acquires various types of information from each medical image diagnostic apparatus 30, and stores the acquired information in the storage unit 10a.

  The storage unit 10a stores examination reservation information registered through the in-hospital network 2. Specifically, the communication unit 10c acquires examination reservation information from the client terminal 20 via the in-hospital network 2, and stores the acquired examination reservation information in the storage unit 10a. Thereby, for example, the storage unit 10a stores the start time of each of a plurality of examinations scheduled to be performed using the medical image diagnostic apparatus 30-1 on April 10, 2013.

  The management unit 10b has a function of managing a power supply unit included in each of the plurality of medical image diagnostic apparatuses (30-1, 30-2, 30-3,..., 30-n). Then, the management unit 10b sets the power mode of each of the plurality of medical image diagnostic apparatuses (30-1, 30-2, 30-3,..., 30-n) to either the operation mode or the power saving mode. An instruction to switch to is sent based on the examination reservation information.

Yes. As shown in FIG. 4, the first level power saving mode is a power saving mode for “stopping the reconfiguration engine”. However, “stopping the reconstruction engine” does not necessarily completely turn off the power supplied to the hardware of the image reconstruction unit 336. “Stop the reconstruction engine” shown in FIG. 4 saves all the data in the memory of the image reconstruction unit 336 to the hard disk of the console device 330 and reduces the power supplied to the hardware of the image reconstruction unit 336. It means that Alternatively, “stop the reconstruction engine” shown in FIG. 4 means to reduce the power supplied to the hardware of the image reconstruction unit 336 while leaving the data in the memory of the image reconstruction unit 336 as it is. means.

  Further, as shown in FIG. 4, the second level power saving mode is a power saving mode of “stopping the X-ray system” in addition to the first level power saving mode. Here, “stopping the X-ray system” means, for example, turning off the power (filament current) supplied to the X-ray tube 312a and supplying the power to the cooling device attached to the X-ray tube 312a. It means turning off the power.

  Further, as shown in FIG. 4, the third level power saving mode is a power saving mode of “stopping the detection system” in addition to the second level power saving mode. Here, “stopping the detection system” means, for example, turning off the power supplied to the heater connected to the detector 313.

  FIG. 5 shows conditions (transition enable conditions) that can be shifted to the power saving mode of each level shown in FIG. 4 and times (recovery time) required for recovery from the power saving mode of each level. In the example shown in FIG. 5, the condition for enabling the transition from the operation mode to the first level power saving mode indicates that the “reconfiguration queue is complete”. Further, the example shown in FIG. 5 indicates that the recovery time from the first level power saving mode to the operation mode is “5 minutes”.

  Further, the example shown in FIG. 5 indicates that the condition for enabling the transition from the operation mode to the second level power saving mode is “no inspection scheduled within 20 minutes”. In the example shown in FIG. 5, the recovery time from the second level power saving mode to the operation mode or the recovery time from the second level power saving mode to the first level power saving mode is “10 minutes”. It is shown that. The recovery time of the second level power saving mode is the time including the time required for warming up the X-ray tube 312a.

  Further, the example shown in FIG. 5 indicates that the condition for enabling the transition from the operation mode to the third level power saving mode is “no inspection scheduled for 2 hours or more”. In the example shown in FIG. 5, the recovery time from the third level power saving mode to the operation mode or the recovery time from the third level power saving mode to the second level power saving mode is “1 hour”. It is shown that. The recovery time of the third level power saving mode is a time including a time required for warming up the detector 313.

  The communication unit 10c acquires the power management information corresponding to FIGS. 4 and 5 from each medical image diagnostic apparatus 30 and stores it in the storage unit 10a. Specifically, the communication unit 10c acquires the power management information corresponding to FIGS. 4 and 5 from the administrator (examiner) of each medical image diagnostic apparatus 30, and stores the power management information in the storage unit 10a.

  The management unit 10b of the server 10 refers to the transferable condition stored in the storage unit 10a as the power management information, and instructs each medical image diagnostic apparatus 30 to shift to the power saving mode of the corresponding level. . Further, the management unit 10b may perform the transition to the power saving mode by changing the level from the first level to the second level, for example. In addition, when the examination reservation time approaches, the management unit 10b instructs the cancellation of the power saving mode at the current level when the current level power saving mode can be transferred. In such a case, the management unit 10b may cancel the power saving mode by changing the level from the second level to the first level, for example.

  The management performed by the management unit 10b for the medical image diagnostic apparatus 30-1 that is an X-ray CT apparatus will be specifically described below. For example, in the first case where “next examination start time−reconfiguration queue completion time” is less than 5 minutes, the management unit 10b sends an instruction to maintain the operation mode to the medical image diagnostic apparatus 30-1.

  Further, for example, in the second case where “next inspection start time−reconfiguration queue completion time” is 5 minutes or more and less than 20 minutes, the management unit 10b issues an instruction to shift from the operation mode to the first level power saving mode. The image is sent to the medical image diagnostic apparatus 30-1. For example, the management unit 10b cancels the first level power saving mode and sends an instruction to shift to the operation mode to the medical image diagnostic apparatus 30-1 5 minutes before the next examination start time. Release of the first level power saving mode means restart of the reconfiguration engine.

  Further, for example, in the third case where “next inspection start time−reconfiguration queue completion time” is 20 minutes or more and less than 2 hours, the management unit 10b issues an instruction to shift from the operation mode to the second level power saving mode. The image is sent to the medical image diagnostic apparatus 30-1. Alternatively, for example, the management unit 10b shifts from the operation mode to the first level power saving mode, and then instructs the medical image diagnostic apparatus 30 to shift from the first level power saving mode to the second level power saving mode. To -1.

  In the third case, for example, the management unit 10b instructs the medical image diagnostic apparatus 30-1 to cancel the second level power saving mode and shift to the operation mode 10 minutes before the next examination start time. To send. Alternatively, in the third case, for example, the management unit 10b issues an instruction to cancel the second level power saving mode and shift to the first level power saving mode 10 minutes before the next examination start time. It is sent to the diagnostic device 30-1. Thereafter, for example, the management unit 10b sends an instruction to cancel the first level power saving mode and shift to the operation mode to the medical image diagnostic apparatus 30-1 5 minutes before the next examination start time. Transition from the second level power saving mode to the first level power saving mode means restart of the X-ray system.

  For example, in the fourth case where “next examination start time−reconfiguration queue completion time” is 2 hours or longer, the management unit 10b issues an instruction to shift from the operation mode to the third level power saving mode for medical image diagnosis. Send to device 30-1. Alternatively, for example, the management unit 10b shifts from the operation mode to the first level power saving mode, then shifts from the first level power saving mode to the second level power saving mode, and then shifts to the second level power saving mode. An instruction to shift from the power saving mode to the third level power saving mode is sent to the medical image diagnostic apparatus 30-1.

  In the fourth case, for example, the management unit 10b issues an instruction to cancel the third-level power saving mode and shift to the operation mode one hour before the next examination start time. To send. Alternatively, in the fourth case, for example, the management unit 10b issues an instruction to cancel the third level power saving mode and shift to the second level power saving mode one hour before the next examination start time. It is sent to the diagnostic device 30-1. Thereafter, for example, the management unit 10b cancels the second level power saving mode 10 minutes before the next examination start time, and instructs the medical image diagnostic apparatus to shift the first level power saving mode to the operation mode. Send to 30-1. Thereafter, for example, the management unit 10b sends an instruction to cancel the first level power saving mode and shift to the operation mode to the medical image diagnostic apparatus 30-1 5 minutes before the next examination start time. The transition from the third level power saving mode to the second level power saving mode means restart of the detection system.

  FIG. 6 is a diagram for explaining an overview of server management processing according to the first embodiment. The management unit 10b included in the server 10 extracts the appointment time for the examination using the medical image diagnostic apparatus 30-1 from the examination reservation information. Then, referring to the power management information illustrated in FIGS. 4 and 5, the management unit 10 b sends a restart instruction based on the reserved time to the medical image diagnostic apparatus 30-1 as illustrated in FIG. 6. . The management unit 10 b performs such management processing on each medical image diagnostic apparatus 30. Thereby, the server 10 according to the first embodiment enables the power modes of the plurality of medical image diagnostic apparatuses (30-1, 30-2, 30-3,..., 30-n) included in the management system 1. Can be collectively managed.

  In the first embodiment, each medical image diagnosis apparatus 30 is switched from the operation mode to the power saving mode, and each medical image diagnosis apparatus 30 is switched from the power saving mode to the operation mode. This can be done in multiple levels of power saving modes recommended by device 30. For this reason, it is possible to prevent an unnecessary failure from occurring in each device constituting each medical image diagnostic apparatus 30 due to a sudden change in the power supplied from the power supply unit. The first embodiment may be a case where the power saving mode of each medical image diagnostic apparatus 30 is one stage.

  When restarting including warm-up of the X-ray system or restarting including warm-up of the detection system, it is necessary to check the situation around the examination room. For this reason, in the first embodiment, the server 10 needs to send a restart instruction and obtain confirmation from an operator (such as a laboratory technician) of the medical image diagnostic apparatus 30 that is the management target of the power mode. It becomes. Therefore, when the operator who has approved the instruction to shift to the operation mode received from the management unit 10b is authenticated as a legitimate operator, the medical image diagnostic apparatus 30 to be managed in the power mode is informed of the transition instruction. Execute. That is, even when the power mode is collectively managed, the medical image diagnostic apparatus 30 that is the power mode management target does not cancel the conventional security system.

  FIG. 7 is a diagram illustrating an example of authentication processing performed in the management system according to the first embodiment. For example, when the X-ray system restart instruction is received, the control unit 338 of the medical image diagnostic apparatus 30-1 displays the GUI shown in the left diagram of FIG. In this GUI, as shown in the left figure of Fig. 7, the "OK" button and the "Cancel" button are displayed along with the words "X-ray system must be restarted. Do you want to restart?" The Here, when the operator who has approved the restart of the X-ray system operates the mouse of the input device 331 to move the cursor onto the “OK” button and clicks the mouse, the control unit 338 controls, The display device 332 displays a GUI for inputting a user name and password, as shown in the middle diagram of FIG.

  Then, when the user name and password input by the operator match the user name and password registered in advance, the control unit 338 determines that the operator who has approved the restart of the X-ray system is an authorized operator. Authenticate that Then, under the control of the control unit 338, the display device 332 displays the characters “Authentication was successful. Rebooting” as shown in the left diagram of FIG. Then, the control unit 338 controls the power supply unit 340 to turn on the power supply to the X-ray irradiation control unit 311.

  By performing the authentication process illustrated in FIG. 7, for example, since the photographing start time is slightly delayed, the restart process can be performed in accordance with the request of a legitimate operator who wants to slightly delay the restart time. Further, by performing the authentication process illustrated in FIG. 7, it is possible to prevent a person other than the authorized operator from approving the restart by mistake.

As described above, in the first embodiment, the server 10 collectively manages the power modes of all medical image diagnostic apparatus groups included in the management system 1 based on the examination reservation information.
Since all the power modes included in the management system 1 can be managed, the server 10 according to the first embodiment can cope with not only the inspection according to the reservation but also the emergency inspection. . That is, the server 10 according to the first embodiment can achieve both power consumption reduction and emergency response. This point will be described in detail in the second embodiment.

It is at least one medical image diagnostic apparatus 30 designated accordingly.

  In the second embodiment, the telephone group shown in FIG. 8 is incorporated into the management system 3 via the in-hospital network 2 functioning as a telephone network in order to accept an emergency examination request.

  In other words, the management unit 10b performs power mode management in response to an emergency inspection request in conjunction with the emergency telephone 50. Moreover, the management part 10b manages the electric power mode according to the request | requirement of an emergency inspection in response to the hospital telephones 40-1 to 40-5. The in-hospital phones 40-1 to 40-5 are devices connected to the in-hospital network 2 by wire. In other words, the management unit 10b performs power mode management in response to an emergency examination request in conjunction with a device wired to the hospital network 2. Further, the management unit 10b performs power mode management in response to an emergency examination request in conjunction with a wireless terminal (portable terminal 40-6) wirelessly connected to the hospital network 2. The management unit 10b receives the operation information set for each telephone, thereby accepting an emergency inspection request.

  Hereinafter, the processing of the management unit 10b according to the second embodiment will be specifically described with reference to FIGS. It is a figure for demonstrating the management part which concerns on 2nd Embodiment.

  For example, as shown in FIG. 9A, a device to be managed in the power mode in response to an emergency examination request includes a plurality of medical image diagnostic devices (30-1, 30-2, 30-3,. All of 30-n).

  Alternatively, for example, as shown in FIG. 9B, the device that is the management target of the power mode in response to the emergency examination request is a medical image diagnostic device 30-1 (X Line CT apparatus), medical image diagnostic apparatus 30-2 (X-ray diagnostic apparatus), and medical image diagnostic apparatus 30-3 (MRI apparatus). The medical image diagnostic device group other than the emergency response device group is set as, for example, a medical image diagnostic device group for examination reservation correspondence.

  Alternatively, for example, as shown in FIG. 9C, the device that is the management target of the power mode corresponding to the emergency examination request is specified by the doctor who accepted the emergency examination request based on the condition of the patient. The medical image diagnostic apparatus 30-1 (X-ray CT apparatus) and the medical image diagnostic apparatus 30-2 (X-ray diagnostic apparatus).

  The setting method shown in FIGS. 9A and 9B is applied, for example, when a person who has received a request for an emergency test cannot determine the type of test that is required. In addition, the designation method shown in FIG. 9C is applied, for example, to a doctor who has received an emergency examination request.

  For example, FIGS. 10 and 11 show an example in which the setting method shown in FIG. 9A or the setting method shown in FIG. 9B is applied. Below, the case where the setting method shown to (B) of FIG. 9 is set to the management part 10b is demonstrated. In FIG. 10, the telephone operator of the emergency telephone 40-1 receives an emergency request from the emergency telephone 50. For example, the telephone operator presses a button provided on a desk for the telephone operator. Such a button is connected to the in-hospital network 2, and information indicating that the button has been pressed is received by the communication unit 10 c of the server 10.

  The communication unit 10c notifies the management unit 10b of information that the operator console button has been pressed. Since the notified emergency inspection request is based on information indicating that the button on the operator's desk has been pressed, the management unit 10b determines that the device to be transferred to power saving energy, that is, the device to be restarted Is determined to be an emergency response device group. Then, the management unit 10b makes an inquiry from the history of power management performed by itself or by making an inquiry to each control unit of the emergency response device group, for example, the medical image diagnostic device 30- It is determined that 1 is the power saving mode. Then, as shown in FIG. 10, the server 10 (management unit 10 b) sends a restart instruction due to an emergency request to the medical image diagnostic apparatus 30-1.

  On the other hand, in FIG. 11, when there is a sudden change in the inpatient, for example, the nurse presses the button of the hospital phone 40-5 of the nurse station. For example, the nurse presses the button “#” of the in-hospital phone 40-5, and further presses “0”. As a result, information indicating that “#, 0” has been pressed is received by the communication unit 10 c of the server 10 via the hospital network 2.

  Since the notified emergency inspection request is “#, 0”, the management unit 10b determines that the device to be transferred to the power saving energy is an emergency response device group. Then, the management unit 10b makes an inquiry from the history of power management performed by itself or by making an inquiry to each control unit of the emergency response device group, for example, the medical image diagnostic device 30- It is determined that 1 is the power saving mode. Then, as shown in FIG. 11, the server 10 (the management unit 10 b) sends a restart instruction by in-hospital emergency communication to the medical image diagnostic apparatus 30-1.

  As a modification shown in FIG. 10, the telephone operator transfers the emergency telephone 50 connected to the emergency telephone 40-1 to the hospital telephone 40-2. The doctor who uses the in-hospital phone 40-2 hears the condition of the patient from the user of the emergency phone 50, and, for example, the medical image diagnostic apparatus 30-1 (X-ray CT apparatus) and the medical image diagnostic apparatus 30-2 ( It is determined that an examination by an X-ray diagnostic apparatus is necessary. Then, for example, the doctor presses the button “#” of the in-hospital phone 40-2, and further presses “1” and “2”. As a result, information indicating that “#, 1, 2” has been pressed is received by the communication unit 10 c of the server 10 via the hospital network 2.

  Since the notified emergency examination request is “#, 1, 2”, the management unit 10b determines the devices to be transferred to power saving energy as the medical image diagnostic device 30-1 and the medical image diagnostic device 30. -2. Then, the management unit 10b makes an inquiry from the history of power management performed by itself, or by making an inquiry to the respective control units of the medical image diagnostic device 30-1 and the medical image diagnostic device 30-2 of the emergency response device group. For example, it is determined that the medical image diagnostic apparatus 30-1 is in the power saving mode. Then, the server 10 (management unit 10b) sends a restart instruction due to an emergency request to the medical image diagnostic apparatus 30-1.

  As a modification shown in FIG. 11, a doctor on duty who receives an emergency call at the mobile terminal 40-6 by calling the in-hospital phone 40-5 installed at the nurse station, hears the patient's condition, for example, Therefore, it is determined that the examination by the medical image diagnostic apparatus 30-1 is necessary. Then, for example, the doctor presses the button “#” of the mobile terminal 40-6, and further presses “1”. As a result, information indicating that “#, 1” has been pressed is received by the communication unit 10 c of the server 10 via the hospital network 2.

  Since the notified emergency examination request is “#, 1”, the management unit 10b determines the devices to be transferred to power saving energy as the medical image diagnostic device 30-1 and the medical image diagnostic device 30-2. It is determined that Then, the management unit 10b makes an inquiry from the history of power management performed by itself or by making an inquiry to the control unit 338 of the medical image diagnostic device 30-1 of the emergency response device group, for example, the medical image diagnostic device 30- It is determined that 1 is the power saving mode. Then, the server 10 (management unit 10b) sends a restart instruction due to an emergency request to the medical image diagnostic apparatus 30-1.

  The button operation described in the above description is merely an example, and the operation for the management unit 10b to determine the content of the emergency inspection request can be arbitrarily changed by the administrator of the management system 3. In addition, devices for making an emergency examination request include, for example, a nurse call button arranged on the bedside, an emergency examination button arranged on the bedside, and an emergency examination arranged on the wall of the hospital room. It may be a dedicated button. These buttons are also devices connected to the in-hospital network 2 in a wired manner, and the management unit 10b manages the power mode in response to an emergency examination request in conjunction with the buttons connected to the in-hospital network 2 in a wired manner. Further, the device for making an emergency inspection request may be a client terminal 20 capable of wired communication or wireless communication.

  Here, in order to respond to the emergency inspection, it is desirable that the operation mode can be promptly shifted. Therefore, the management unit 10b according to the second embodiment uses all or some of the plurality of medical image diagnostic apparatuses (30-1, 30-2, 30-3,..., 30-n). The level of the power saving mode of the image diagnostic apparatus (for example, the emergency response apparatus group) may be set to a level that can be shifted to the operation mode within a predetermined time. For example, the management unit 10b sets the level of the power saving mode of the medical image diagnostic apparatuses 30-1, 30-2, and 30-3 to level 2 that can be shifted to the operation mode within 10 minutes (see FIG. 5). reference).

  Next, processing of the server 10 according to the second embodiment will be described with reference to FIG. FIG. 12 is a flowchart illustrating a processing example of the server according to the second embodiment.

  As illustrated in FIG. 12, the management unit 10b of the server 10 according to the second embodiment determines whether an emergency inspection request has been received (step S101). Here, when the request | requirement of an emergency test | inspection is not received (step S101 negative), the management part 10b waits until it receives the request | requirement of an emergency test | inspection. In addition to the emergency inspection, the management unit 10b performs management based on the inspection reservation information described in the first embodiment in parallel.

  On the other hand, when a request for an emergency test is received (Yes at Step S101), the management unit 10b acquires the power mode of the medical image diagnostic apparatus group for emergency response determined from the information regarding the request for the emergency test (Step S102). And the management part 10b determines whether all the acquired electric power modes are operation modes (step S103). Here, when all the acquired power modes are operation modes (Yes at Step S103), the management unit 10b ends the emergency response process accepted at Step S101. Thereafter, the management unit 10b performs the determination in step S101 again.

  On the other hand, when all the acquired power modes are not in the operation mode (No in step S103), the management unit 10b sends an instruction to shift the medical image diagnostic apparatus in the power saving mode to the operation mode (step S104), and step S101. End the emergency response process accepted in step 1. Thereafter, the management unit 10b performs the determination in step S101 again.

  As described above, in the second embodiment, by using the management unit 10b that manages the power mode of all the medical image diagnostic apparatus groups, the emergency medical image diagnostic apparatus groups are collectively shifted to the operation mode. . Therefore, in the second embodiment, it is possible to achieve both power consumption reduction and emergency response. In the second embodiment, a telephone network is incorporated in the management system 3, and various medical workers in the hospital use the telephone connected to the telephone network to make an emergency examination request. The group of medical image diagnostic apparatuses can be easily and collectively shifted to the operation mode. Here, a device (such as a PC or a mobile phone) for making an emergency inspection request may be connected to the hospital network 2 via a dedicated line. For example, the mobile terminal 40-6 may be connected to the hospital network 2 via a VPN (Virtual Private Network). In such a case, the management unit 10b performs power mode management in response to an emergency examination request in conjunction with a device connected to the hospital network 2 via a dedicated line. By using a dedicated line such as VPN, it is possible to avoid an emergency inspection request from a malicious third party.

  In the second embodiment, for example, the power saving mode of the emergency response device group is set to a level at which the operation mode can be restarted within 10 minutes. Thereby, in 2nd Embodiment, the emergency response apparatus group can be restarted rapidly, for example. In addition, when performing level setting, it can be changed to any level depending on whether power consumption or emergency response is emphasized.

  In the above description, the case where the device that manages the power mode at the time when the request for the emergency examination is received is the medical image diagnostic device group. Here, normally, the management system 3 (management system 1) is provided with an image processing apparatus that performs analysis by image processing on medical image data captured by the medical image diagnostic apparatus 30. Such an image processing apparatus is, for example, a workstation for image processing. When image diagnosis is not performed, the image processing apparatus is normally shut down, in a sleep mode state, or in a rest state. It takes time to restart such an image processing apparatus as compared with a general PC.

  For this reason, in order to quickly perform image diagnosis using medical image data taken in an emergency examination, an image processing apparatus that analyzes medical image data taken by the medical image diagnostic apparatus that has been shifted to the operation mode is provided. It is desirable to be in an operable state, that is, an operation mode that can be analyzed by image processing.

  Therefore, the management unit 10b according to the modification of the second embodiment analyzes the medical image data captured by the medical image diagnostic apparatus that has transmitted an instruction to shift to the operation mode when the emergency examination request is received. When the power mode of the image processing apparatus to be performed is the power saving mode, an instruction to shift to the operation mode is sent to the image processing apparatus. FIG. 13 is a diagram for explaining a modification of the second embodiment.

  For example, as illustrated in FIG. 13, the management unit 10 b of the server 10 sends a restart instruction in response to an emergency request to the medical image diagnostic apparatus 30-1 and medical images taken by the medical image diagnostic apparatus 30-1. A restart instruction in response to an emergency request is also sent to the image processing apparatus 60 that performs data analysis. As a result, the control unit of the image processing apparatus 60 controls the power supply unit of the own apparatus to restart the image processing engine of the image processing apparatus 60.

  In the modification of the second embodiment, it is possible to efficiently perform an emergency response inspection by extending the management target of the power mode to the image processing apparatus group.

  In the first and second embodiments, the server 10 that performs overall management of the management system 1 and the management system 3 manages the power mode of the medical image diagnostic apparatus group in the system. The case where it functions as was explained. However, the first and second embodiments described above are cases where a management device that manages the power mode of the medical image diagnostic device group in the system is installed independently of the server 10. Also good.

  In the first embodiment and the second embodiment described above, the function of the management device that manages the power mode of the medical image diagnostic device group in the system is incorporated in, for example, the medical image diagnostic device 30-1. It may be the case. Further, the first embodiment and the second embodiment described above may be, for example, a case where the storage unit 10a and the management unit 10b are distributed and installed in different devices.

  That is, each component of each device illustrated in the first embodiment and the second embodiment is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to the one shown in the figure, and all or a part of the distribution / integration is functionally or physically distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. Further, all or a part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.
