It is.

(First embodiment)
First, a first embodiment will be described with reference to FIGS. In the present embodiment, an example will be described in which wireless restriction is performed based on area information related to wireless restriction, and processing such as confirmation processing is performed in advance before wireless restriction is performed.

  FIG. 1 is a side sectional view of a radiation imaging unit 10 mounted on the radiation imaging apparatus according to the present embodiment, and FIG. 2 is a configuration example of a mobile radiation imaging apparatus 20 (a control apparatus that controls radiation imaging). It is a figure for demonstrating.

  In FIG. 1, reference numeral 1 denotes a radiation detection panel, which includes a fluorescent plate 1a, a photoelectric conversion element 1b, and a substrate 1c. A glass substrate is often used as the substrate 1c. The glass substrate is used because it has no chemical action with the semiconductor element, can withstand the temperature of the semiconductor process, and has dimensional stability. Photoelectric conversion elements 1b are formed in a two-dimensional array on the substrate 1c by a semiconductor process. As the fluorescent plate 1a, a metal plate phosphor coated on a resin plate is used, and is integrated by adhesion to the substrate 1c. The radiation detection panel 1 is fixedly supported on a metal base 2, thereby ensuring mechanical strength.

  Reference numeral 3 denotes a circuit board on which an electronic component 3a that processes an electrical signal converted by the photoelectric conversion element 1b is mounted. The circuit board 3 is connected to the photoelectric conversion element 1 b by a flexible circuit board 4 and is fixed to a protrusion 2 a provided on the back side of the base 2. The base 2 is fixed to a housing main body 5a of the housing 5 through a support portion 2b, and is sealed by a radiation transmissive housing lid 5b of the housing 5 so that radiation as one electronic cassette is provided. An imaging unit 10 is formed. In addition, the radiation imaging unit 10 includes a battery 6 that supplies power to the circuit board 3 and the like, and a wireless communication unit 7 that is responsible for signal transmission such as image signals and control signals. An electrical contact terminal 6b for charging the battery 6 is disposed on a part of the housing body 5a.

  As shown in FIG. 2, the radiation imaging unit 10 is combined with a radiation generation unit and can be mounted on a movable radiation imaging apparatus 20. The radiation imaging apparatus 20 includes a radiation imaging unit 10, a main body unit 21, a bottom unit 22, a support column 26, an arm 27, a radiation generation unit 28, and a storage unit 30. A plurality of wheels 23 and wheels 24 are provided on the bottom portion 22 of the main body portion 21, whereby the entire radiation imaging apparatus 20 can be arbitrarily moved. The bottom 22 has a detection unit 25 that detects the rotation of the wheel 24, and has a function of detecting the movement state of the radiation imaging apparatus 20. The detection unit 25 can be realized by a simple method such as a rotary encoder.

  The support column 26 is provided to be rotatable in a substantially vertical direction and around the axis in front of the main body portion 21. The arm 27 extends in a substantially horizontal direction with respect to the column 26 and is supported by the column 26 so as to be movable in the substantially vertical direction. The radiation generator 28 including a radiation tube is attached to the tip of the arm 27 so as to be movable in the horizontal direction along the arm 27 and the irradiation direction can be arbitrarily adjusted.

  The main body unit 21 is provided with a storage unit 30 for storing the radiation imaging unit 10 and can store the radiation imaging unit 10 during movement. The radiation imaging unit 10 is taken out from the storage unit 30 during use. The storage unit 30 may be formed integrally with the main body unit 21 or may be formed separately from the main body unit 21. The main body unit 21 includes a battery 31, a control unit 32, an input / output unit 33, an external communication unit 34, a wireless communication unit 35, and a reception unit 36.

  The battery 31 supplies power necessary for various components. The control unit 32 performs driving of the radiation tube included in the radiation generation unit 28, control of the entire radiation imaging apparatus 20, control of the radiation imaging unit 10, and the like. The control unit 32 communicates with the radiation imaging unit 10 using the wireless communication unit 35, stores information such as a radiation image in an internal memory, and links the radiation generation unit 28 and the radiation imaging unit 10 together. Or the power supply from the battery 31 to various components is controlled.

  The input / output unit 33 includes a monitor for display output and an operation reception unit for receiving input from the operator, and is used for operation of the radiation imaging apparatus 20. In the present embodiment, it is arranged on the upper part of the main body 21. For example, the operation reception unit may be configured with a physical button for switching the selection position on the monitor, a touch panel, or the like.

  On the monitor, an imaging region is selected, the radiographic imaging unit 10 is changed to a radiographable state, and imaging conditions such as a tube voltage, a tube current, and an irradiation time of the radiation generating unit 28 are set. An operation menu is displayed, and the operator uses the operation reception unit to select each item and perform shooting. In addition, a series of operations may be performed until the captured image is subjected to processing such as trimming or rotation using the operation accepting unit and is stored in the image recording unit built in the control unit 32.

  The control unit 32 manages various types of information such as ordered patient information, imaging conditions, and imaging history, and the operator can check a list of patient information through the input / output unit 33. Such information is transmitted / received to / from an external device in the hospital via an external communication unit 34 connected to the control unit 32.

  When photographing, a wireless communication unit 35 that communicates exclusively with the wireless communication unit 7 built in the radiation imaging unit 10 is used. The control unit 32 transmits an imaging command under the conditions set by the input / output unit 33 to the radiation imaging unit 10. A radiation image captured in synchronization with the radiation generation unit 28 is transmitted from the radiation imaging unit 10. The captured radiographic image is stored in an image recording unit in the control unit 32 and finally transferred to an external device.

  The receiving unit 36 receives predetermined information for recognizing wireless communication restrictions. The control unit 32 recognizes the restriction of wireless communication based on information transmitted from a transmission unit provided outside, and restricts wireless communication by the external communication unit 34 and the wireless communication unit 35.

  In the present embodiment, as shown in FIG. 3, a transmitter 41 that transmits a predetermined signal is provided in a transmitter 40 provided on a facility wall surface or the like. The combination of the transmitter 41 and the receiver 36 can determine the proximity of the radiation imaging apparatus 20 to the transmitter 40. It can be recognized that the time when the radiation imaging device 20 passes the vicinity of the transmission device 40 is closest to the transmission device 40. What is necessary is just to determine the reception intensity | strength of the predetermined signal transmitted from the transmission part 41, and to determine that it was the closest when it became the strongest intensity | strength.

  Alternatively, it may be determined that the reception intensity is closest when the reception intensity exceeds a preset threshold. Alternatively, it may be detected that the radiation imaging apparatus 20 has approached within a predetermined distance from an area where wireless communication is restricted, depending on the reception intensity. In response to the detection, before moving to an area where wireless communication is restricted, image data that has already been captured may be transferred to an external device, or whether or not there is a new imaging order may be confirmed.

  For example, in the hospital floor having the layout as shown in FIG. 4, it is assumed that the area A1 is a space in which devices that are easily affected by wireless communication are installed and should be restricted wirelessly. On the other hand, hospital rooms of hospitalized patients are area A2 and area A3. Here, wireless communication is required for round trip imaging. The area A4 is a passing area for going back and forth between the area A1, the area A2, and the area A3. Area A4 is an area for preparing for switching the wireless communication restriction. The transmitting device 40 is disposed near the entrance of the area A2, the transmitting device 42 is disposed near the entrance of the area A1, and the transmitting device 44 is disposed near the entrance of the area A3. Moreover, the transmission device 43 is arranged in the vicinity of the elevator entrance. Each transmitting device 40, 42, 43, 44 has a transmitting unit 41, and transmits predetermined information. The radiation imaging apparatus 20 can receive information transmitted from each transmission apparatus and recognize the relative proximity between the current position of the radiation imaging apparatus 20 and each transmission apparatus.

  Hereinafter, with reference to the flowchart of FIG. 5, an operation procedure of processing performed by the radiation imaging apparatus 20 according to the first embodiment will be described. In step S100, the control unit 32 charges the battery 31 with a commercial power source connected via an AC cable (not shown) as a preparation state. In step S <b> 101, the control unit 32 acquires order information from an external device such as an in-hospital RIS (Radiology Information System) terminal via the external communication unit 34.

  In step S102, the input / output unit 33 displays the acquired order information. The displayed order information includes patient information such as a patient name and sex, a room number, imaging requirements such as an imaging region and an imaging posture, and the like. The operator confirms the displayed order information and plans a rough schedule for the round trip taking into consideration the priority of the hospital round and the travel route. In step S103, the control unit 32 detects the removal of the AC cable from the commercial power source.

  In step S <b> 104, the control unit 32 detects that the operator has started moving to a predetermined hospital room along the planned schedule while pressing the radiation imaging apparatus 20. Here, the control unit 32 manages the flag value Fe for managing the restriction level of the wireless communication in the area. The types of areas include, for example, a radio-enabled area, a radio switching preparation area, and a radio restricted area, and 0, 1, and 2 are assigned as flag values, respectively. Each transmitting device transmits a flag value corresponding to the area in which each transmitting device is included in a predetermined signal. Here, the wireless area is an area where wireless communication can be performed without restriction. The wireless restricted area is an area that restricts wireless communication itself because there is a possibility of affecting a device arranged in the area by wireless communication. The radio switching preparation area is an area other than the radio-enabled area and the radio restricted area, and is an area in which necessary switching preparation is performed before radio communication is restricted in preparation for entering the radio restricted area. The flag value Fe can be used as information for determining whether or not wireless communication is possible.

  In step S105, the control unit 32 detects that the radiation imaging apparatus 20 has passed through the transmission apparatus based on predetermined information received from the transmission apparatus. The passage detection may be determined based on the reception intensity of a predetermined signal received from the transmission device. When the passage of the transmission device is detected, the process proceeds to step S106. On the other hand, when the passage of the transmission device is not detected, the process proceeds to step S107.

  In step S106, the control unit 32 receives predetermined information transmitted from the transmission unit of the transmission device, and the flag value Fe held by the control unit 32 based on the flag value data included in the information. To change. Thereafter, the process proceeds to step S107.

  In step S107, the control unit 32 determines whether or not the flag value Fe = 2. That is, it is determined whether or not the area to which the radiation imaging apparatus 20 is moved is a wireless restricted area. If the flag value Fe = 2, the process proceeds to step S108. On the other hand, when the flag value is not Fe = 2 (when Fe = 0 or 1), the process proceeds to step S110.

  For example, as shown in FIG. 4, a transmission device 43 is disposed at an elevator doorway. The transmission unit of the transmission device 43 notifies that it is a switching boundary to the flag value Fe = 1. The flag value Fe is changed to 1 when the operator moves the radiation imaging apparatus 20 and goes down the elevator and passes through the transmission apparatus 43. Further, the transmission unit of the transmission devices 40 and 44 notifies that it is a switching boundary to the flag value Fe = 0, and the transmission unit of the transmission device 42 notifies that it is a switching boundary to the flag value Fe = 2. Yes.

  In step S108, the control unit 32 restricts wireless communication. In step S109, the control unit 32 notifies the operator that the wireless communication control has been switched. In step S110, the control unit 32 cancels the wireless communication control.

  In step S111, the control unit 32 determines whether or not the flag value Fe = 0. That is, it is determined whether or not the area to which the radiation imaging apparatus 20 is moved is a wireless-enabled area. If the flag value Fe = 0, the process proceeds to step S112. On the other hand, when the flag value is not Fe = 0 (when Fe = 1, that is, when it is a radio switching preparation area), the process proceeds to step S115.

  In step S <b> 112, the control unit 32 detects that the movement of the radiation imaging apparatus 20 has stopped after reaching a predetermined hospital room such as the section A <b> 2 or the section A <b> 3. The operator adjusts the position of the radiation generating unit 28 with respect to a predetermined imaging posture, selects an imaging region on the monitor of the input / output unit 33, and sets the tube voltage and tube current (mA) of the radiation generating unit 28. An imaging condition such as a mAs value that is a product of time (sec) is set. When preparation is completed, shooting is performed.

  In step S <b> 113, the control unit 32 reflects the fact that the photographing has been completed when the photographing is completed, and updates the list. In addition, the radiation imaging unit 10 is returned to the storage unit 30 by the operator when the imaging is completed.

  In step S114, the operator checks the shooting order. If the order remains, the process returns to S105. And it moves to the next hospital room etc. and repeats a series of flows. On the other hand, if no photographing order remains, the process proceeds to S117.

  In step S115, the control unit 32 executes preprocessing for limiting wireless communication. This is because the radiography apparatus 20 moves to the radio switching preparation area (area A4 in FIG. 4) of Fe = 1, that is, an area adjacent to the radio restricted area (area A1 in FIG. 4), and thus enters the area A1. The possibility is assumed in advance to prepare for future radio restrictions. Specifically, the control unit 32 automatically inquires of an external management system whether there is an urgent photographing order, obtains a new order, transfers photographed image data, and sets an image transfer priority item. Perform pre-processing such as confirmation.

  In step S116, when the process of S115 is completed, the control unit 32 displays a message indicating that the pre-processing is completed on the monitor of the input / output unit 33 or performs a voice notification. Further, a message indicating that the radiation imaging apparatus 20 is approaching the wireless restricted area may be displayed or voiced. Upon receiving this message, the operator may select whether or not to continue the movement.

  In step S115, the control unit 32 may further collect information on the state of the radiation imaging unit 10 from the wireless communication unit 7 of the radiation imaging unit 10. Information on the state may include any of battery state, sensor driving state, and internal temperature information. In step S116, the control unit 32 may check the presence or absence of information that may interfere with shooting based on the information about the state, and display or notify a message that prompts a predetermined treatment if necessary. .

  In addition, the control part 32 cancels | releases a radio | wireless restriction, when the radiography apparatus 20 passes the transmission apparatus 42, and leaves to a radio | wireless switching preparation area (area A4), order information, radiography, etc. A process for confirming information related to the state of the unit 10 is performed, and if there is a change in the situation, a message is displayed or notified. For example, in addition to the above-described passage detection, the flag value currently held by the radiation imaging apparatus 20 is Fe = 2, and the flag value data included in the information newly received from another transmitting apparatus is Fe = 1. In some cases, it can be determined that the user has left the radio restricted area (area A1) to the radio switching preparation area (area A4).

  In step S117, the control unit 32 determines whether or not the radiation imaging apparatus 20 has arrived at the predetermined standby base and returned. If it is determined that it has been returned, the process proceeds to step S118. On the other hand, if it is determined that it has not been returned, the process returns to step S105.

  In step S118, the control unit 32 outputs the processing result of the imaging order to the RIS, and ends the round imaging.

  As described above, in the present embodiment, the radio restriction is performed based on the area information related to the radio restriction, and the process such as the confirmation process is performed in advance before performing the radio restriction. Can often perform round trips. According to the present embodiment, it is possible to provide information related to the wireless restriction to the user in advance and reduce the occurrence of inappropriate wireless communication.

(Second Embodiment)
The second embodiment will be described with reference to FIGS. In the present embodiment, an example will be described in which not only wireless communication but also wired communication is possible between the radiation imaging apparatus main body and the radiation imaging unit, and wireless or wired switching is possible. The same reference numerals as those in the first embodiment are used for common elements constituting the radiation imaging apparatus and the radiation imaging unit.

  FIG. 6 is a side cross-sectional view of the radiation imaging unit 50 included in the radiation imaging apparatus according to the present embodiment, and FIG. 7 is a diagram for explaining a configuration example of the mobile radiation imaging apparatus 60 according to the present embodiment. It is.

  As shown in FIG. 6, the radiation imaging unit 50 includes a communication unit 9 that is responsible for signal transmission such as image signals and control signals. When used in a wireless state, power is supplied from the battery 6 to the circuit board 3 and the like, and communication is performed using a wireless communication function built in the communication unit 9. On the other hand, when a wired cable is used instead of wireless, the wired cable is connected from the outside to the connector 8 formed on the exterior of the housing body 5a. Since power supply and communication are performed directly via a wired cable, battery instability and wireless communication instability are eliminated.

  As shown in FIG. 7, when imaging is performed in combination with the radiation imaging apparatus 60, a wireless communication unit 35 that communicates exclusively with the communication unit 9 built in the radiation imaging unit 50 is used. On the other hand, when the radiation imaging unit 50 is used not by radio but by wire, the cable 61 connected to the control unit 32 is used. By connecting the connector 62 at the tip of the cable 61 to the connector 8 of the radiation imaging unit 50, power supply and communication can be performed by wire.

  The control unit 32 of the radiation imaging apparatus 60 receives the switching signal transmitted from the transmission unit of the transmission apparatus as described in the first embodiment, and switches between wired / wireless. Before the radiation imaging apparatus 60 enters the wireless restricted area, the wired / wireless switching is performed, and the wireless restricted area is controlled to use the wired line.

  Hereinafter, with reference to the flowchart of FIG. 8, a procedure of processing performed by the radiation imaging apparatus 60 according to the second embodiment will be described. The control unit 32 manages a flag value Fe for managing the restriction level of radio communication in the area. The types of areas according to the present embodiment include, for example, a wireless area, a wireless / wired switching area, and a wired area (wireless restriction area), and 0, 1, and 2 are assigned as flag values, respectively. Each transmitting device transmits a flag value corresponding to the area in which each transmitting device is arranged, as in the first embodiment.

  Since each process of step S200-S208, S210, S213-S215, S219-S220 is the same as each process of step S100-S108, S110, S112-S114, S117-S118, description is abbreviate | omitted.

  In step S209, after the wireless communication is restricted in S208, the control unit 32 informs the operator that the wireless restriction has been made and that the switch to wired has not yet been made. This prompts the operator to switch to wired.

  In step S211, the control unit 32 determines whether or not the flag value Fe = 0. That is, it is determined whether or not the area to which the radiation imaging apparatus 60 is moved is a wireless area. If the flag value Fe = 0, the process proceeds to step S212. On the other hand, when the flag value is not Fe = 0 (when Fe = 1, that is, when it is a wireless / wired switching area), the process proceeds to step S216.

  In step S212, the control unit 32 determines whether the wired or wireless setting and the area information are appropriate, and if it is possible to perform shooting, the process proceeds to step S213, and shooting is performed wirelessly or wired. On the other hand, if the situation is that shooting is not possible, the process returns to step S205.

  In step S216, the control unit 32 executes pre-switching processing. If wireless communication is currently being performed, the duration of wireless communication is estimated. When data with a large amount of information such as image information is being communicated, the data is temporarily interrupted, and when the amount of information is small, such as additional order information, it is continued.

  When the communication content is image information transfer from the radiation imaging unit 50, the radiography unit 50 is instructed to save the image in the internal memory, and then interrupted. In the case of image transfer with an external device such as an external management system, a message to the effect of interruption is transmitted to the management system, and image data is stored in an untransmitted memory in the radiation imaging apparatus 60. The processing is similarly interrupted when the state of wireless communication is bad due to some trouble.

  In step S217, after the wireless communication is completed, the control unit 32 makes an announcement for an instruction to switch to wired connection. If the process cannot be completed normally, a message to that effect may be displayed or notified.

  In step S218, the operator switches from wireless to wired according to the switching instruction. The switching operation is performed by connecting the connector 62 of the cable 61 extending from the main body and the connector 8 of the radiation imaging unit 50. When it detects that a wired cable is connected, it automatically switches to wired communication.

  As described above, in this embodiment, wireless or wired switching is performed, and wireless communication is restricted and wired communication is used in the wireless restricted area. As a result, it is possible to reduce the influence on other devices such as in-hospitals by observing restrictions on wireless communication without being conscious of the operator.

(Third embodiment)
A third embodiment will be described with reference to FIGS. 9 and 10. In this embodiment, an example will be described in which the restriction of wireless communication can be grasped for each area. The same reference numerals as those in the first embodiment are used for common elements constituting the radiation imaging apparatus and the radiation imaging unit.

    FIG. 9 is a diagram showing an example of a shooting order management list according to the present embodiment. The control unit 32 associates the shooting location 901 (shooting area information) with the communication form 902 indicating the presence / absence of wireless restriction, and manages each correspondence as an information table. When the shooting areas are 1F, 2F, 3F of Building A, 3F, 4F of Building B, the communication mode is wireless communication, and when the shooting area is 1F, 2F (ICU) of Building B, wired communication.

  The information table is configured such that editing, registration, deletion, and the like can be input by the operator via the input / output unit 33. For example, input is performed using an interface displayed on the monitor of the input / output unit 33. The control unit 32 determines a communication mode to be used for shooting for each shooting order from the shooting location information included in the shooting order and the information table.

  FIG. 10 shows a display example of the input / output unit 33 (display unit) according to the present embodiment. A combination of examination ID, patient ID and name, imaging order, imaging location, and communication form is displayed and controlled as an imaging order management work list. For example, 2F of Building A is registered in the wireless area, and radio communication is possible for the imaging in the hospital room indicated by A205. An icon indicating that wireless communication is possible (four vertical lines having different lengths) is displayed on the right side of the row of A205, and the operator determines whether wired or wireless by checking this icon. be able to. On the other hand, an icon (a figure imitating a cable) indicating that wired communication is to be performed is displayed on the right side of the row of ICU01.

  Note that icons may be displayed in different colors and contrasts so that it can be recognized whether the current communication form is an appropriate setting. For example, the icon may be displayed in green when appropriate, red in inappropriate, or the icon may be displayed lighter with lower contrast than appropriate when inappropriate. Further, when the operator selects the next shooting from the order list, if the communication mode is not appropriate, a message that prompts switching may be displayed or voiced. Thus, by making it easy to confirm whether or not the current communication form is appropriate for each shooting order, inappropriate use can be prevented. Further, it may have a function of sorting the shooting order management work list. For example, by extracting and displaying areas where wireless communication can be used, the operator can efficiently examine routes.

  Although the embodiment of the present invention has been described above, the following processing may be further performed. Specifically, in the area where wireless communication is restricted, an unusable frequency or an unusable frequency may be displayed on the display unit of the input / output unit 33. For example, information such as “2.4 GHz is usable but 5 GHz is unusable” and “IEEE802.11b is usable but IEEE802.11a is unusable” may be displayed.

  In addition, when the radiographing order is acquired from the RIS, if the radiocommunication restricted area is included in the radiographing area corresponding to the radiographing order, the operator may be informed that a wired cable is required at the roundabout.

  Furthermore, when the radiographic imaging unit and the radiographic imaging apparatus main body are not connected by a wired cable in an area where wireless communication is restricted, a warning may be notified to prompt the operator to connect the wired cable. In addition to or instead of this, radiography may be prohibited. For example, the reception of imaging conditions may be controlled to be unacceptable, the exposure switch may be locked so that the exposure switch cannot be pressed, or the exposure switch may be controlled so as not to react even if it is pressed.

  Even when wireless communication is restricted, there are cases where it is desired to perform shooting in an emergency. Therefore, a physical button that accepts an input for permitting wireless communication in an emergency may be provided. In addition to the physical buttons, a virtual button may be provided on a touch panel or the like by configuring a GUI in the input / output unit.

  Further, in order to detect entry or exit from one area to another area, two transmitting devices may be arranged in a state of being separated by a predetermined distance near the entrance / exit of the area. You may comprise so that an approach or exit may be recognized by receiving two information transmitted from each transmitter, and determining the moving direction of a radiography apparatus based on the change of each received intensity.

(Other embodiments)
The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, etc.) of the system or apparatus reads the program. It is a process to be executed.
