1st Embodiment With reference to FIGS. 1-5, the structure of the radiography system 100 by embodiment of this invention is demonstrated. FIG. 1 is a diagram illustrating a configuration example of a radiation imaging system 100 according to the first embodiment of the present invention. The radiation imaging system 100 includes a radiation generation unit 101 including a radiation control unit 111 and a tube 121, a radiation imaging unit 102 including a plurality of radiation imaging devices 112 as an example of one or more radiation imaging devices 112, and a plurality of control terminals. A control terminal unit 103 including 113 is included. Further, the radiation imaging system 100 includes a radiation information system (RIS) 105, an image storage and communication system (PACS) 106, a storage server 107, an imaging workstation (WS) 108, and a reservation management. A system 109 is included. These components of the radiation imaging system 100 are connected to each other via a communication path 104. The communication path 104 is not limited to the hospital network, and the RIS 105 and the PACS 106 may be connected to an external cloud service or the like. Further, in the configuration of FIG. 1, one radiation generation unit 101 is arranged, but a plurality of radiation generation units 101 may be arranged. Further, in the configuration shown in FIG. 1, the radiation imaging unit 102 includes a plurality of radiation imaging devices 112 of the radiation imaging devices 112-1 to 112-m, but includes only one radiation imaging device 112. Also good.

  Each of the control terminals 113 for a user (such as a doctor or a radiographer) to operate the radiation imaging apparatus 112 can be connected to and cooperate with each of the plurality of radiation imaging apparatuses 112. The connection between the radiation imaging apparatus 112 and the control terminal 113 may be established by, for example, IEEE 802.11 standard wireless LAN communication. The wireless LAN communication may be a wireless LAN access point (not shown) connected to the communication path 104, or a so-called infrastructure mode communication in which either the radiation imaging apparatus 112 or the control terminal 113 operates as an access point to communicate. Further, the wireless LAN communication may be an ad hoc mode communication in which the radiation imaging apparatus 112 and the control terminal 113 directly communicate with each other. Further, the connection between the radiation imaging apparatus 112 and the control terminal 113 is not limited to wireless connection, and may be wired communication such as Ethernet (registered trademark).

  The control terminal 113 can display the state of the connectable radiation imaging apparatus 112 (for example, whether it is in power saving standby, whether imaging preparation is completed, etc.). Further, the radiation imaging apparatus 112 being linked can be controlled by an operation from the control terminal 113 by the user. A radiographic image obtained by irradiating the radiographic apparatus 112 with radiation may be transferred to and displayed on the associated control terminal 113 so that the user can check the radiographic image after imaging. Further, the control terminal 113 may associate the radiographing order information received from the RIS 105 with the radiographic image after radiography. Further, the control terminal 113 communicates the radiographic image associated with the imaging order information to the storage server 107 that stores the radiographic image and the image inspection WS 108 that performs image processing and generates a final image for diagnosis. It may be output via 104. The control terminal 113 may be a stationary terminal such as a desktop PC installed in the radiation imaging room, or may be a built-in terminal built in the round-trip car. Furthermore, the control terminal 113 may be a portable terminal such as a tablet PC or a smartphone owned by the user. In particular, when the control terminal 113 is a portable terminal, it is easy to carry, and if the radiation generation unit 101 used for film or computer radiography (CR) is used as it is and upgraded to digital radiography (DR), it is initial. Investment can be suppressed. Further, the portable control terminal 113 is useful in that it can be used for emergency medical treatment at a disaster site by being combined with the portable radiation generating unit 101 that is easy to carry.

  The reservation management system 109 functions as a reservation management unit for managing the reservation status of each of the plurality of radiation imaging apparatuses. In the reservation management system 109, a plurality of radiation imaging apparatuses 112-1 to 112-m are registered. The reservation management system 109 has a memory 119 for storing reservation information of the radiation imaging apparatus 112 for each of the registered radiation imaging apparatuses 112-1 to 112-m. In addition, in the memory 119 of the reservation management system 109, user information for identifying a user that is registered when the user operates each of the plurality of control terminals 113 is registered. A user whose user information is registered connects to the reservation management system 109 using any one of the control terminals 113, and the user desires to use one of the one or more radiation imaging apparatuses 112-1 to 112-m. The inquiry information including the date and time to be transmitted is transmitted to the reservation management system 109. This inquiry information may include a date and time when the user desires to acquire a radiation image. The date and time when any of the radiation imaging apparatuses 112-1 to 112-m is desired to be used is the date and time when the radiation imaging apparatuses 112-1 to 112-m are used and the radiation imaging apparatuses 112-1 to 112-1 are used. 112-m can be included in the end date and time of use. Further, the date and time when the acquisition of the radiographic image is desired may include the date and time when the acquisition of the radiographic image starts and the date and time when the acquisition of the radiographic image ends. The reservation management system 109 is a radiation imaging apparatus that matches the inquiry information among the plurality of radiation imaging apparatuses 112-1 to 112-m, based on reservation information including the date and time when each of the plurality of radiation imaging apparatuses is reserved. Whether or not 112 is present is determined. The date and time when the use of any of the radiation imaging apparatuses 112-1 to 112-m is reserved is the date and time when the use of any of the radiation imaging apparatuses 112-1 to 112-m is started and the radiation imaging apparatus 112-1. 112-m can be included in the end date and time of use. If there is a radiation imaging apparatus 112 that matches the inquiry information, the reservation of the radiation imaging apparatus 112 at the desired date and time is added to the reservation information. The reservation management system 109 does not accept reservations of other users for the radiation imaging apparatus 112 of the reserved date and time. The user controls the radiation imaging apparatus 112 by linking the radiation imaging apparatus 112 from the control terminal 113 according to the reservation.

  Here, when the reservation information and user information are associated with the cooperative operation between the radiation imaging apparatus 112 and the control terminal 113, the user mistakenly makes a reservation between the radiation imaging apparatus 112 and the control terminal 113. It is possible to prevent cooperation. For example, the user information is added to the reservation information by including the user information in the inquiry information when the user makes a reservation for the radiation imaging apparatus 112. When receiving the cooperation request from the control terminal 113, the radiation imaging apparatus 112 collates the reservation management system 109 with the user information of the control terminal 113 and the reservation information with the radiation imaging apparatus 112 at that time. The reservation management system 109 is reserved among the plurality of radiation imaging apparatuses 112-1 to 112-m for the control terminal 113 in which user information that matches the user information of the reservation information is registered among the plurality of control terminals 113. The operation (cooperation) of the radiation imaging apparatus 112 is permitted at the reserved date and time. On the other hand, when another user has reserved the radiation imaging apparatus 112 that has received the cooperation request, the reservation management system 109 cooperates with the control terminal 113 that has transmitted the cooperation request and the radiation imaging apparatus 112 that has received the cooperation request. Reject (operation). As a result, a user other than the user who has made a reservation cannot use the reserved radiation imaging apparatus 112. If there is no reservation information in the radiation imaging apparatus 112 at the time when the cooperation request is received, the reservation management system may give the control terminal 113 permission for an operation (cooperation) on the radiation imaging apparatus 112. In addition, here, associating the user information with the cooperative operation between the radiation imaging apparatus 112 and the control terminal 113 has been described, but the present invention is not limited to this. For example, in addition to patient information (for example, an ID number set for identification in a facility such as a hospital) in reservation information, patient information of a patient who entered a radiation room to take a radiation image, and radiation You may link the cooperation operation | movement between the imaging device 112 and the control terminal 113. FIG.

  In addition, the reservation management system 109 sets the reservation time in the control terminal 113 in which user information that matches the user information of the reservation information is registered among the plurality of control terminals 113-1 to 113-n, It may be informed that the time is approaching. The reservation management system 109 informs the control terminal 113 that another user has made a use reservation when another user's reservation time comes while the control terminal 113 and the radiation imaging apparatus 112 are linked. May be. For example, the reservation management system 109 considers a case where one radiation imaging apparatus 112 among a plurality of radiation imaging apparatuses 112-1 to 112-m is continuously reserved by different users. In this case, among the plurality of control terminals 113, there is a next reservation in the control terminal 113 in which user information that matches the user information of the reservation information of the previous reservation is registered, or the time of the next reservation is approaching. You may make it alert | report. By such notification, the user can know that a reservation is made by another user.

  Next, an example of a flow for making a reservation for use of the radiation imaging apparatus 112 by the reservation management system 109 using the control terminal 113 will be described with reference to FIG. First, in step S <b> 201, the user inputs a user ID and password using the control terminal 113 and logs in to the reservation management system 109. Note that the login is performed in order that the reservation management system 109 specifies a user who has made a reservation. In order to save the trouble of inputting the user ID and password, the reservation management system 109 may be logged in using login information for specifying the user stored in the control terminal 113. FIG. 3 shows an example of a reservation screen of the control terminal 113 when logging into the reservation management system 109 and transitioning to the reservation screen. Inquiry information when the user makes a reservation for the radiation imaging apparatus 112, such as an order number, a scheduled use date and time where the user wants to obtain a radiation image, and the like can be input. In step S202, the user inputs inquiry information such as an order number, scheduled use date and time, and usage location. The order number, the scheduled use date and time, and the place of use may be input in any format. For example, a method of directly inputting a character string or a method of selecting a graphically displayed icon may be used.

  On the reservation screen, confirmation of reservation information of each radiation imaging apparatus 112 including other users and priority setting can also be performed. When the user presses the reservation information confirmation button, the screen transits to a screen for confirming the reservation status of each radiation imaging apparatus 112, and the reservation can be confirmed or canceled. In addition, when the user presses the priority setting button, the priority setting screen is displayed, and the user can set an arbitrary priority to be described later. In the configuration of FIG. 3, reservation execution, confirmation of reservation information, and priority setting are displayed on one reservation screen. However, the screen display method is not limited to this, and the display screen of each button is divided. May be. Next, when the user presses the reservation button, the process proceeds to step S203. In step S203, the reservation management system 109 performs a listing process for creating a list of the radiation imaging apparatuses 112-1 to 112-m based on the inquiry information input by the user in step S202 and the priority setting specified by the user. . In step S203, the reservation management system 109 inputs a user's input from among the plurality of radiation imaging apparatuses based on reservation information including the date and time when each of the plurality of radiation imaging apparatuses 112-1 to 112-m is reserved. It is determined whether there is a radiation imaging apparatus 112 that matches the inquiry information. The determination result includes information on the radiation imaging apparatus 112 that matches the inquiry information among the plurality of radiation imaging apparatuses 112-1 to 112-m. The control terminal 113 that has transmitted the inquiry information among the plurality of control terminals 113-1 to 113-n displays information on the radiation imaging apparatus that matches the inquiry information based on the determination result. Next, in step S204, the user selects and reserves an arbitrary radiation imaging apparatus 112 from the list displayed on the control terminal 113. Since the radiographic apparatus 112 suitable for the user is displayed in order by the listing process in step S203, the complexity when the user selects the radiographic apparatus 112 is eliminated.

  FIG. 4 is an example of the flow of the listing process performed by the reservation management system 109 shown in step S203. When the reservation management system 109 determines that one of the plurality of radiation imaging apparatuses 112-1 to 112-m matches the inquiry information, the reservation management system 109 uses the determination result as at least the inquiry information among the plurality of control terminals 113. Is output to the control terminal 113 that has transmitted. On the other hand, when two or more radiation imaging apparatuses 112 out of the plurality of radiation imaging apparatuses 112-1 to 112-m match the inquiry information, the reservation management system 109, based on the apparatus status information and inquiry information described later, The degree of conformity to the inquiry information of two or more radiation imaging apparatuses is determined. The control terminal 113 that has transmitted the inquiry information among the plurality of control terminals 113 displays a list of two or more radiation imaging apparatuses in accordance with the fitness.

  Specifically, first, in step S401, the reservation management system 109 reads the inquiry information input by the user. The reservation management system 109 may read additional inquiry information from the RIS 105 based on the order number input by the user. The inquiry information at this time includes at least one information among patient information, imaging technique, number of images to be captured, and the like. Next, the reservation management system 109 calculates the size of the area to be imaged and the required number of radiation imaging apparatuses 112 from the imaging technique information read in step S401 in step S402. The required number of radiation imaging apparatuses 112 is calculated as, for example, that one radio imaging apparatus 112 is necessary for general imaging, and two or more radiographic imaging apparatuses 112 are required for long imaging. The reservation management system 109 reads from the shooting technique information whether the shooting mode is moving image shooting or still image shooting. That is, in addition to the date and time when the user desires to obtain a radiographic image, the inquiry information includes the size of the area to be imaged, the number of radiographs, the number of radiographic apparatuses 112 necessary for radiographic image capture, and the radiographing mode. Including at least one of them.

  Next, in step S403, the reservation management system 109 extracts the radiation imaging apparatus 112 that is not reserved at the date and time that the user desires to make a reservation.

  Next, the reservation management system 109 acquires apparatus state information indicating each state of the radiation imaging apparatus 112 extracted in step S404. The apparatus status information may include information on the specification of each radiation imaging apparatus 112. The specification information of the radiation imaging apparatus 112 includes, for example, at least one of information such as the name of the radiation imaging apparatus 112, the power source to be used, the size of the imaging area, the executable communication mode, and the executable imaging mode.

  As the name of the radiation imaging apparatus 112, a serial number or the like of each radiation imaging apparatus 112 may be displayed. The name of the radiation imaging apparatus 112 may be a name set for identification in a facility such as a hospital where the user uses the radiation imaging system 100 with an individual identification ID.

  Information indicating the size of the imaging region is necessary to select the radiation imaging apparatus 112 having an appropriate size in accordance with the physique of the patient to be imaged and the imaging technique. For example, the information indicating the size of the imaging region may be information such as the size of a pixel region in which the radiation image of the radiation imaging apparatus 112 can be captured.

  The radiation imaging system 100 includes a radiation imaging apparatus 112 having a plurality of communication modes such as wired communication by cable and wireless communication, and a radiation imaging apparatus 112 having only a wired or wireless communication mode. Yes. Further, the communication speed may vary depending on each radiation imaging apparatus 112. For this reason, such information may be displayed on the control terminal 113 as information on a communication mode that can be implemented.

  The radiation imaging system 100 includes a radiation imaging apparatus 112 capable of capturing both a capturing mode for capturing a moving image and a capturing mode for capturing a still image, a radiation capturing apparatus 112 capable of capturing only a still image, and the like. Can be mixed. Also, in the radiation imaging system 100, the radiation imaging apparatus 112 that communicates with the radiation generation unit 101 to perform imaging synchronously, or the radiation imaging apparatus 112 itself detects the start of radiation irradiation without being synchronized with the radiation generation unit 101. The radiation imaging apparatus 112 that performs imaging may be mixed. For this reason, even if information such as whether or not a moving image or still image can be captured and whether or not there is synchronization with the radiation generation unit 101 is displayed on the control terminal 113 as information on possible shooting modes. Good.

  Further, the apparatus state information includes information indicating the state of each radiation imaging apparatus 112 that is expected at the current date and time desired by the user, in addition to the specification information of each radiation imaging apparatus 112. The information indicating this state includes, for example, the charging state of the built-in power supply mounted in the radiation imaging apparatus 112, the remaining amount of internal storage capacity, error information, failure information, use history, calibration information, use frequency, use place, etc. Includes location information.

  The plurality of radiation imaging apparatuses 112-1 to 112-m can include a radiation imaging apparatus 112 that can be operated not only by power supply from the outside but also by power supply from a built-in power source. The built-in power source is often a storage element such as a secondary battery represented by a lithium ion battery or a lithium ion capacitor, but is not limited to this as long as it can operate without receiving external power supply. The built-in power supply may be in a removable form or may be a built-in type that cannot be removed. The state of charge of the built-in power supply may be indicated by the charge amount as a percentage, or by the usable time or the number of images that can be taken.

  The radiation imaging apparatus 112 can have an internal storage capacity such as a large-capacity nonvolatile memory for holding image data therein without losing the captured image. In addition, the radiation imaging apparatus 112 has an imaging mode in which image data is not transmitted to the control terminal 113 for each imaging, but is stored in this internal storage capacity, and image data is transmitted to the control terminal 113 at a later time. In some cases. This internal storage capacity is realized by, for example, a NOR flash memory, a NAND flash memory, an SD card, or the like. The current remaining capacity of the internal storage capacity may be displayed as device status information.

  The error information and failure information indicate information regarding the internal state of the radiation imaging apparatus 112, such as whether it can be used for imaging or whether the operation is limited. If it cannot be used due to a temporary error or failure, the user is prompted to select another radiation imaging apparatus 112 by, for example, being hidden on the list when displayed on the control terminal 113 described later. it can.

  As usage history and usage frequency information, what kind of imaging the radiation imaging apparatus 112 has been used in the past, from which control terminal 113 it was used, usage history at the control terminal 113 that cooperates in the reservation, The usage frequency may be displayed. Further, for example, the extent to which the radiation imaging apparatus 112 is used as a whole of the radiation imaging system 100 may be displayed.

  As the calibration information, information indicating whether periodic calibration of the radiation imaging apparatus 112 that must be performed in units of one year, for example, is performed within the calibration deadline or is currently being performed may be indicated. A radiation imaging apparatus 112 whose calibration deadline has passed or a radiation imaging apparatus 112 that is performing calibration is hidden on the list at the time of display on the control terminal 113, which will be described later. The user can be prompted to make a selection.

  The positional information such as the usage location of the radiation imaging apparatus 112 includes, for example, the positional relationship between the control terminal 113 and the radiation imaging apparatus 112, the positional relationship between the location where imaging is performed and the radiation imaging apparatus 112, and the like. The positional information may be displayed by calculating a positional relationship by a GPS (Global Positioning System) receiving unit provided in at least one of the control terminal 113 and the radiation imaging apparatus 112. The position information may be obtained by communicating with the control terminal 113 and the cradle that houses the radiation imaging apparatus 112 whose installation positions are fixed.

  Next, in step S405, the reservation management system 109 determines whether or not to operate by power feeding from the built-in power source on which the radiation imaging apparatus 112 extracted in step S403 is mounted. If it is determined in step S405 that the operation is performed by the power supply from the built-in power supply, the reservation management system 109 performs the operations from step S406 to S408 on the radiation imaging apparatus 112 that is operated by the power supply from the built-in power supply. If it is determined in step S405 that the radiation imaging apparatus 112 does not operate due to power supply from the built-in power supply, the process proceeds to S409. In step S406, the reservation management system 109 calculates the state of charge of the radiation imaging apparatus 112 determined to be operated by power supply from the built-in power supply and the estimated remaining charge amount at the date and time desired by the user estimated from the reservation information. . For example, the reservation management system 109 subtracts the amount of power consumption calculated from the total number of shots registered in the reservation information until the desired time input by the user from the current charge state, and estimates the remaining charge amount. .

  Next, in step S407, the reservation management system 109 calculates the amount of charge required in the radiation imaging apparatus 112 from the number of radiographs extracted in step S401. Next, in step S408, the reservation management system 109 compares the estimated remaining charge amount calculated in step S406 with the required charge amount calculated in step S407, and the estimated remaining charge amount is greater than or equal to the required charge amount. A certain radiation imaging apparatus 112 is extracted. Next, in step S409, the reservation management system 109 sets the total number of extracted imaging devices by excluding the radiation imaging devices 112 that are not extracted in step S408 from the radiation imaging devices 112 extracted in step S403. If the total number of extracted imaging devices is equal to or greater than the required number calculated in step S402, the process proceeds to step S411. If the total number of extracted imaging devices is less than the required number, the process proceeds to step S410. In step S410, the reservation management system 109 displays a list indicating that reservation cannot be made on the control terminal 113 that transmitted the inquiry information because there is no radiation imaging apparatus 112 that matches the inquiry information among the plurality of radiation imaging apparatuses 112. Finish the process.

  In step S411, the reservation management system 109 determines the degree of fitness for the inquiry information of the radiation imaging apparatus 112 extracted in each of the above steps based on the apparatus state information and the inquiry information. For example, when the size of the area to be imaged and the size of the imaging area of the radiation imaging apparatus 112 are closer, the fitness is determined to be higher. In addition, for example, the fitness level is determined to be higher when the control terminal 113 and the radiation imaging apparatus 112 are arranged closer to each other. The radiographic apparatus 112 that is more suitable for the user's wishes can be determined to have a higher fitness. The control terminal 113 that has transmitted the inquiry information displays a list of two or more radiation imaging apparatuses in a state where they can be listed according to the fitness. The display order of the list is arranged and displayed in advance based on the matching degree of predetermined device state information. For example, in accordance with the inquiry information received from the RIS 105 in step S401, the reservation management system 109 determines that the radiographic imaging device 112 suitable for the radiographic part and radiographing technique specified in the radiography is high and has a higher rank. You may make it display. Further, when the user has set priority, the priority may be displayed in the order in which the priority is set. For example, when the priority setting is not set, the reservation management system 109 determines the suitability by giving priority to the size of the imaging region of the radiation imaging apparatus 112, but the user gives priority to the charge state of the built-in power supply. If it is set to determine, the user setting is followed. In this case, for example, the reservation management system 109 may determine that the radiation imaging apparatus 112 having a large estimated remaining charge amount calculated in step S406 has a high fitness.

  When the process proceeds from step S409 to step S410, the radiation imaging apparatus 112 is not displayed as a list in step S204. In other words, the reservation management system 109 does not display on the control terminal 113 the radiation imaging apparatus 112 that does not conform to the inquiry information among the plurality of radiation imaging apparatuses 112-1 to 112-m. At this time, the reservation management system 109 may display that the reservation cannot be made to the control terminal 113 that has transmitted the inquiry information among the plurality of control terminals 113-1 to 113-n. The user changes the reservation time in response to the notification performed in step S410. In step S410, the reservation management system 109 may display the date and time when the radiation imaging apparatus 112 suitable for the inquiry information input by the user is not reserved on the control terminal 113 that has transmitted the inquiry information.

  FIG. 5 shows an example of a list display displayed on the control terminal 113. FIG. 5 shows a case where the suitable shooting area size is calculated as 17 × 14 inches and the required charging amount is 40% from the inquiry information input by the user, and the priority setting is set to the shooting area size and the estimated remaining charging amount. It is a display example. In this example, it is determined that the identification ID: FPD-7 is most suitable for the inquiry information, and FPD-7 is displayed at the top. In the configuration shown in FIG. 5, in addition to the identification ID, the list displays the estimated use location immediately before as the size, estimated remaining charge amount, and position information of the imaging region of the radiation imaging apparatus 112. The size of the imaging region is the size of the radiation imaging apparatus 112 extracted in step S404. The estimated remaining charge amount is the estimated remaining charge amount of the radiation imaging apparatus 112 calculated in step S406. The immediately preceding estimated use place is a use place registered in the reservation information reserved immediately before the time the user desires to make a reservation. Further, when there is no reservation from the point in time when the user performs a reservation operation until the time of use, the immediately presumed use place can be displayed based on the position information extracted in step S404. By displaying the estimated place of use immediately before, the user can select the radiation imaging apparatus 112 with a short moving distance. Further, since the FPD-3 does not have a built-in power supply and operates by external power feeding, the estimated remaining charge amount is described as “−”. In addition, FPD-2 and FPD-6 are registered in the reservation management system 109, but are not displayed on the list because the estimated remaining charge amount calculated in step S408 is less than 40%. An example is shown in FIG. The user selects one or a plurality of target radiation imaging apparatuses 112 from the list and makes a reservation.

  The information displayed on the control terminal 113 is not limited to the above four types. The information displayed on the control terminal 113 includes, for example, the communication mode that can be implemented by the radiation imaging apparatus 112, the imaging mode that can be implemented, the remaining storage capacity, error information, failure information, usage history, calibration information, and usage frequency. Any one or more of these may be displayed.

  Further, in this embodiment, importance is placed on the visibility of the display list, and the reservation management system 109 selects the radiation imaging apparatus 112 that has not been extracted in steps S403 and S408, that is, does not match the inquiry information, in step S411. Is not displayed. However, the present invention is not limited to this, and the reservation management system 109 may display the radiation imaging apparatus 112 that does not match the inquiry information in step S411. Accordingly, for example, by displaying the radiation imaging apparatus 112 that has not been extracted in step S408 on the radiation imaging apparatus 112 that operates with the built-in power supply, this radiation is displayed at a time when the user does not have a reservation before the reservation time. The imaging device 112 can be charged.

  In the present embodiment, the reservation management system 109 extracts apparatus state information of the radiation imaging apparatus 112 in step S404. At this point, the reservation management system 109 may perform processing for excluding from the list radiographic imaging devices 112 that do not clearly match the imaging technique or the size of the imaging area calculated in step S402. Further, at the same timing, the reservation management system 109 may perform a process of excluding from the list even when the remaining amount of the internal storage capacity of the radiation imaging apparatus 112 is smaller than the number of imaging images extracted from the RIS 105.

  Further, in this embodiment, the reservation management system 109 calculates the remaining charge amount in step S406. At this time, the total number of shots included in the reservation information after the time when the user wishes to make a reservation is entered. May be further subtracted. If the remaining charge amount is insufficient with respect to the subtraction result, it is not an extraction target in step S408, so that it is possible to prevent shooting with a date and time reservation after the previous reservation.

  In the present embodiment, the order number, the shooting date / time for which shooting is desired, and the place of use are entered as the inquiry information in step S202. However, a special number other than the inquiry information registered in the RIS 105 is entered or not entered in the order number. It may be input. For example, when the radiation imaging apparatus 112 is calibrated, a number associated with the calibration different from the normal order number is registered in the reservation management system 109. When the user inputs the number in the order number and inputs the imaging date / time and the place of use, the reservation management system 109 may list all the radiation imaging apparatuses 112 in step S203. In this case, the reservation management system 109 may display only the radiation imaging apparatus 112 whose calibration deadline is close.

  In the present embodiment, the reservation of the radiation imaging apparatus 112 is associated with the user by inputting the user ID, but may be associated with the control terminal 113. In this case, the reservation management system 109 includes information for distinguishing individual control terminals 113 in the memory 119 and does not have to have user information.

  In the present embodiment, the radiation imaging unit 102 includes a plurality of radiation imaging apparatuses 112-1 to 112-m. However, as described above, one radiation imaging apparatus 112 may be provided. In this case, since there is only one target radiographic apparatus 112, for example, step S402 in FIG. 4 may be omitted. Further, for example, in step S204, the control terminal 113 may display only whether or not the radiation imaging apparatus 112 can be used at the date and time desired by the user according to the inquiry information without performing the list display.

  For example, there is a case where the user wants to use the radiation imaging apparatus 112 with a built-in power source having a specified size for a round trip after 3 hours. However, there is a case where it is known immediately before use that another user uses the desired radiation imaging apparatus 112 and the remaining battery level is low, for example, that it is impossible to perform imaging unless switching to another radiation imaging apparatus 112. is there. In addition, when the reserved radiography apparatus 112 is used at a place far from the use place even though the reservation is made, the radiography apparatus 112 is taken to the place or the radiography apparatus 112 is re-executed. Selection is required. As described above, when one or more radiation imaging apparatuses are used by a plurality of users, the efficiency of capturing a radiation image may be reduced. However, as shown in this embodiment, the radiation imaging apparatus 112 can be efficiently used in the radiation imaging system 100 including one or more radiation imaging apparatuses 112-1 to 112-m.
