Description

  The present invention relates to a radiation irradiation apparatus that irradiates a subject with radiation when acquiring a radiation image of the subject.

  Conventionally, as disclosed in Patent Documents 1 to 3, for example, various radiographic imaging apparatuses using a movable radiation irradiation apparatus are known. Such a radiographic imaging device basically holds a leg portion that can be run by wheels, a battery for driving the radiation source, and an electric circuit for driving the radiation source, and is held on the leg portion. The subject is irradiated with radiation using a round-wheel-type radiation irradiating apparatus including a main body, an arm connected to the main body, and a radiation source attached to the arm. .

  In addition, a radiographic imaging device using a portable radiation irradiation device that is equipped with only the minimum components for radiation irradiation, such as a radiation source and an electric circuit, and is operated by an operator by hand is proposed. (See Patent Document 4). Such a portable radiation irradiation device is light enough to be operated by an operator by hand, and can be photographed with a smaller turn than the above-described round-the-wheel radiation irradiation device. ing.

  When a radiographic image of a subject is captured by such a radiographic imaging device, a radiation detector (so-called “Flat Panel Detector”) that normally records a radiographic image representing the subject by irradiation of radiation that has passed through the subject. ) Is used. As such a radiation detector, a cassette type radiation detector in which a control unit such as an image detection unit, a driving battery, and an electric circuit related to driving is housed in a housing is well known. Then, if such a radiation detector is disposed at a position facing the radiation irradiation apparatus with the subject interposed therebetween, and the radiation irradiation apparatus is driven in this state, the radiation transmitted through the subject is detected by the radiation detector. A radiographic image represented by radiation that has been irradiated to the subject and transmitted through the subject is acquired.

  Further, in the radiographic imaging apparatus in which the radiation irradiation apparatus and the radiation detector as described above are separated, the subject is photographed with a camera to represent the surface of the subject for the purpose of recognizing the irradiation field or the like. A technique for acquiring a captured image and displaying it has been proposed (see Patent Documents 1 to 3). Further, in a radiographic imaging device in which the radiation irradiation device and the radiation detector are separate, a deviation between the radiation irradiation field and the detection range of the radiation detector is likely to occur. For this reason, Patent Documents 1 to 3 also propose a method in which a frame indicating the radiation field and a frame indicating the detection area of the radiation detector are superimposed on the displayed captured image.

  The radiation source 19 includes, for example, an X-ray tube, a booster circuit, and a cooling unit that cools the X-ray tube.

  The irradiation control unit 20 drives the radiation source 19 to irradiate the subject H with radiation having intensity corresponding to preset imaging conditions so that the subject H is irradiated for a set time. Control the amount. The imaging conditions are a tube voltage (kV value) and a mAs value (tube current × irradiation time) corresponding to the body thickness of the subject H. The body thickness of the subject H is the SID (Source Image receptor Distance) that is the distance between the device 10 and the surface of the radiation detector 30 and the distance between the device 10 and the surface of the subject H by the distance sensor 27. It can be obtained by measuring SOD (Source Object Distance) and subtracting SOD from SID. Note that the operator may measure the body thickness, and input information for setting imaging conditions including the measured body thickness from the input unit 24 to the apparatus 10. In the present embodiment, information for setting such imaging conditions such as body thickness is transmitted to the console 50, the imaging conditions are set in the console 50, and the set imaging conditions are transmitted to the radiation irradiation apparatus 10. The The irradiation control unit 20 controls the irradiation of the subject H with radiation using the imaging conditions transmitted from the console 50.

  The collimator control unit 21 includes a drive mechanism such as a motor and an electric circuit for controlling the drive mechanism for changing the radiation field of radiation irradiated from the radiation source 19 to the subject H by driving the collimator 14. ing. The collimator control unit 21 controls driving of the collimator 14 in accordance with an instruction from the drive control unit 23.

  The imaging control unit 22 drives the camera 13 to image the surface of the subject H and obtains a captured image G1. Further, the shooting control unit 22 may perform image processing for improving the image quality on the shot image G1 acquired by the camera 13. The captured image G1 acquired by the camera 13 is a moving image having a predetermined frame rate of, for example, 30 fps.

  The drive control unit 23 controls the entire drive of the radiation irradiation apparatus 10. That is, the drive control unit 23 instructs the irradiation control unit 20 to drive the radiation source 19, instructs the collimator control unit 21 to process the collimator 14, and instructs the imaging control unit 22. A process of driving the camera 13 to acquire the captured image G1, a process of displaying various information including the captured image G1 on the monitor 15, a process of instructing the communication unit 25 to exchange various information with the console 50, a battery 26 A process for monitoring the state, a process for receiving an instruction from the input unit 24, a process for measuring the distance between the radiation irradiation apparatus 10 and the object by the distance sensor 27, and a process for detecting the movement of the radiation irradiation apparatus 10 by the motion sensor 28. Etc. Each process described above is performed according to an instruction from the input unit 24 or an instruction transmitted from the console 50 and received by the communication unit 25. The drive control unit 23 corresponds to a photographing permission unit and an emission permission unit.

  The input unit 24 is a touch panel type input unit integrated with the monitor 15, receives an instruction from the operator, and outputs information representing the instruction to the drive control unit 23. Note that the photographing button 18 is also included in the input unit 24. In this way, by using the input unit 24 as a touch panel, it is easy to perform various inputs for the apparatus 10 while holding the grip units 16 and 17 by hand.

  The communication unit 25 communicates with the console 50 wirelessly to exchange information. In addition, it may replace with radio | wireless and the radiation irradiation apparatus 10 and the console 50 may be connected by a cable, and information may be exchanged by wire. In the latter case, the communication unit 25 has a connector to which a cable is connected.

  The motion sensor 28 is a 9-axis motion sensor that detects 3-axis acceleration, 3-axis angular velocity, and 3-axis tilt. The acceleration, angular velocity, and inclination detected by the motion sensor 28 are output to the drive control unit 23 as motion information, used for controlling the radiation irradiation apparatus 10 during imaging, and transmitted from the communication unit 25 to the console 50. The motion sensor 28 corresponds to the motion amount detection means.

  The irradiation field lamp 29 is formed of a light emitting element that emits visible light such as a light bulb or an LED (Light Emitting Diode), and is turned on and off by the drive control unit 23. When the irradiation field lamp 29 is turned on, visible light is irradiated to the irradiation field irradiated with radiation on the subject H.

  Here, a hole for inserting a hand is formed between the gripping portions 16 and 17 and the side surface of the housing 11. Here, “https://www.dh.aist.go.jp/database/hand/data/list.html” shows the average hand width of Japanese men of 83 mm and the maximum value of 95 mm. ing. The width of the hand is defined as “metacarpale radiale with the hand extended (with fingers and palms), the second to fifth fingers aligned, and the thumb abducted. The straight distance from metacarpale ulnare (the point that protrudes to the little finger of the fifth metacarpal head), measured from the back of the hand with the palm on the desk. Is. For this reason, it is preferable to form the grips 16 and 17 so that the length of the hole in the vertical direction is about ± 10 mm, preferably about ± 5 mm, centering on the maximum value of 95 mm. In the following description, the hand size used is shown in “https://www.dh.aist.go.jp/database/hand/data/list.html”.

  The average value of male thumb length is 60.8 mm. Therefore, in order to operate the surface of the touch panel type monitor 15 while holding the grip portions 16 and 17, from the central axis of the connection portions 16 </ b> B and 17 </ b> B of the grip portions 16 and 17 to the side-side end portion of the monitor 15. Is about ± 10 mm, preferably about ± 5 mm, centered on 30 mm, which is about ½ of the thumb length.

  Further, the average value of the hand length from the wrist crease of the male is 183 mm, and the average value of the third finger of the palm length is 105 mm. The length of the palm is defined as "the straight distance from the wrist heel to the tip of the middle finger when the hand is extended (finger and palm)." Measure the distance from the center of the wrist wrinkle to the wrinkle of the middle finger base parallel to the long axis of the hand, with the thumbs abducted and the other four fingers aligned. The case is measured at the most proximal (closer to the body) wrinkles. " For this reason, the thickness of the connecting portions 16B and 17B of the gripping portions 16 and 17 is ± 10 mm centered on 40 mm, which is ½ of the difference between the average value of the hand length and the average value of the palm length third finger, preferably Is preferably ± 5 mm.

  In the present embodiment, the input unit 24 is a touch panel type input unit integrated with the monitor 15, and the operator performs various settings of the radiation irradiation apparatus 10 by touching the monitor 15. Since the operator handles the radiation irradiation apparatus 10 by holding the grip portions 16 and 17 with both hands, in this embodiment, the operation can be performed by touching the monitor 15 with the thumb. Hereinafter, an operation by touching the monitor 15 will be described. The following display on the monitor 15 is performed by the drive control unit 23.

  When the operator touches a part of the monitor 15, setting menus 41 and 42 of the radiation irradiation apparatus 10 are displayed on the left and right ends of the monitor 15 as shown in FIG. 5. FIG. 5 shows a state where the monitor 15 is touched with the thumb of the left hand. The setting menus 41 and 42 may be displayed only at one position where the monitor 15 is touched. Further, it may be displayed with the touched position as the center, or may be displayed with the position in the vicinity slightly away from the touched position as the center.

  The setting menus 41 and 42 are menus for setting parameters of each part of the radiation irradiation apparatus 10 and driving the radiation irradiation apparatus 10. The driving of the radiation irradiating apparatus 10 includes driving of the collimator 14, on / off of the irradiation field lamp 29, and an operation of emitting radiation when the photographing button 18 is not provided.

  Each of the setting menus 41 and 42 includes a plurality of commands 43, and the plurality of commands are displayed so as to be arranged in an arc shape centered on a position touched by a finger or a position in the vicinity thereof. The plurality of commands 43 are displayed in a range that can be reached by a finger from a position touched by the finger. Here, the arrangement of the plurality of commands 43 is not limited to an arc shape, and may be arranged on the circumference of an ellipse or linearly as long as it is within the reach of a finger. When a plurality of commands 43 are displayed in a straight line, the plurality of commands 43 may be arranged in a direction perpendicular to the direction in which the gripping portions 16 and 17 protrude, that is, in the vertical direction of the monitor 15. Since the setting menus 41 and 42 can be swiped, a plurality of commands 43 may be arranged in the horizontal direction of the monitor 15.

  The operator selects a desired command from the setting menus 41 and 42 displayed on the monitor 15. At this time, by swiping the setting menus 41, 42, the setting menus 41, 42 can be rotated to display commands hidden and invisible in the initial state on the monitor 15. At this time, the desired command 43 is selected by continuous taps. Thereby, it is possible to prevent selection of an erroneous command and to reliably select a desired command.

  Next, processing performed at the time of imaging of the subject H using the radiation irradiation apparatus 10 according to the present embodiment will be described. In the present embodiment, the two operators handle the radiation irradiation device 10 and the radiation detector 30 to position the radiation detector 30 behind the subject H and set an irradiation field. Pre-shooting work is performed, and shooting is performed after the pre-shooting work is completed. First, the radiation irradiation apparatus 10 is set above the subject H, the subject H is photographed by the camera 13, and a photographed image G1 of the subject H is acquired.

  The captured image G1 is transmitted to the console 50, processing such as detection by the radiation detector 30 is performed, and various information acquired by the processing is transmitted to the radiation irradiation apparatus 10. Various types of information are displayed on the monitor 15 of the radiation irradiation apparatus 10 so as to be superimposed on the captured image G1.

  FIG. 6 is a diagram showing a captured image G1 on which various types of information are superimposed. As shown in FIG. 6, the captured image G1 displayed on the monitor 15 includes text (here, “standby”) 60 that indicates the driving status of the radiation detector 30, an arrow 61 that indicates the vertical direction of the radiation detector 30, An icon 62 representing the remaining battery level of the radiation detector 30, a detection area 63 corresponding to the detection area of the radiation detector 30, a center position 64 of the radiation detector 30, an irradiation field area 65, a center position 66 of the irradiation field area 65, The text 69 of Detector 1 that is identification information of the radiation detector 30 is superimposed and displayed. In the irradiation field area 65, the center position 66 of the irradiation field is also displayed. In addition, it is preferable to display the detection area 63 and the irradiation field area 65 in an identifiable manner. For example, the color of the detection area 63 and the color of the irradiation field area 65 are preferably different. The color may be specified by an instruction from the console 50.

  Further, it is preferable that the console 50 detects the color of the subject H from the captured image G1 and designates the colors of the detection region 63 and the irradiation field region 65 so as to be different from the color of the clothing. Thereby, it can prevent that the detection area | region 63 and the irradiation field area | region 65 which are superimposed on the picked-up image G1 are mixed with the clothing of the subject H.

  The operators of the radiation irradiation apparatus 10 and the radiation detector 30 perform pre-imaging work in cooperation. That is, the operator of the radiation detector 30 moves the radiation detector 30 to an appropriate position behind the subject H, and the operator of the radiation irradiating apparatus 10 appropriately observes the image displayed on the monitor 15. It is confirmed whether or not the radiation detector 30 has moved to the position. Moreover, the position of the radiation irradiation apparatus 10 is moved if necessary. By this operation, as shown in FIG. 7, the center position 66 of the irradiation field region 65 and the center position 64 of the detection region 63 can be matched.

  Further, in the console 50, it is determined whether or not the center position of the radiation detector 30 matches the center position 66 of the irradiation field region 65. If they match, information indicating the match is sent to the radiation irradiation apparatus 10. You may make it transmit. When the radiation irradiation apparatus 10 receives the information indicating the match, the radiation irradiation apparatus 10 indicates to the monitor 15 that the center position is matched, such as a text “center position is matched” or a mark indicating that the center position is matched. indicate. In FIG. 7, the center position coincides with a star mark 68. Instead of displaying on the monitor 15, the operator is notified that the center position of the radiation detector 30 coincides with the center position 66 of the irradiation field region 65 by, for example, outputting by sound or blinking the monitor 15. If possible, any method may be used.

  Here, in the state shown in FIG. 7, since the irradiation field area 65 is larger than the detection area 63, the radiation that has not passed through the radiation detector 30 among the radiation that has passed through the subject H can be imaged. It can't be done and it becomes useless. Further, irradiating the subject H with such useless radiation increases the exposure amount of the subject H. Therefore, the operator of the radiation irradiation apparatus 10 uses the input unit 24 to give a region matching instruction for matching the irradiation field region 65 and the detection region 63. Note that the area matching instruction is an instruction that the operator operates the irradiation field area 65 displayed on the monitor 15 with a finger or the like to match the irradiation field area 65 with the detection area 63 as shown in FIG. The collimator 14 may be driven by the collimator control unit 21 in conjunction with the area matching instruction. However, if the collimator 14 is driven every time there is an instruction for matching the irradiation field area 65 and the detection area 63, The consumption of increases. For this reason, in the present embodiment, the input unit 24 accepts an input indicating that the preparation for photographing is completed after the region matching instruction for matching the irradiation field region 65 and the detection region 63 using the input unit 24 is completed. In this case, the collimator 14 may be driven by the collimator controller 21.

  When the imaging preparation is completed, the drive control unit 23 detects the movement of the radiation irradiation apparatus 10 by the motion sensor 28 and calculates the movement amount per unit time of the radiation irradiation apparatus 10. The amount of movement of the radiation irradiation apparatus 10 per unit time corresponds to the hand movement of the operator. The drive control unit 23 determines whether or not the amount of motion per unit time is less than the threshold value Th1, and if this determination is negative, the drive control unit 23 displays a warning on the monitor 15. The operator can take measures such as firmly holding the radiation irradiation apparatus 10 by warning display. If the determination is negative, the drive control unit 23 controls the radiation source 19 so as not to emit radiation even when the imaging button 18 is operated. Instead of this, the shooting button 18 may not be operated by locking the shooting button 18 or the like. Further, the threshold value Th1 may be changed according to the radiation irradiation time included in the imaging conditions. For example, when the irradiation time of radiation is long, the influence of camera shake becomes large. Therefore, the threshold value Th1 may be changed so as to decrease as the irradiation time of radiation increases.

  If the determination is affirmative, the operator operates the imaging button 18 so that the drive control unit 23 drives the radiation source 19 to emit radiation toward the subject H. In this case, the drive control unit 23 may display on the monitor 15 that the photographing is possible. If the determination is affirmed after the determination is denied, the drive control unit 23 stops displaying the warning on the monitor 15 and enables the radiation source 19 to be driven by operating the imaging button 18. If the shooting button 18 cannot be operated, the shooting button 18 can be operated by unlocking the shooting button 18 or the like. Thereby, the subject H is irradiated with radiation, the radiation transmitted through the subject H by the radiation detector 30 is detected, and a radiation image is acquired. The acquired radiation image G2 is transmitted to the console 50, subjected to image processing for improving the image quality, and transmitted to the radiation irradiation apparatus 10. In the radiation irradiation apparatus 10, the radiation image G2 can be displayed on the monitor 15 and it can be confirmed whether imaging was successful. In this case, the captured image G1 and the radiation image G2 may be displayed side by side, or the radiation image G2 may be superimposed on the captured image G1.

  As described above, in the present embodiment, the projection protrudes in a direction different from the first direction that coincides with the radiation direction of the radiation and the photographing direction of the photographed image G1, and the second direction that is the display direction of the photographed image. 11 includes a plurality of gripping portions 16 and 17 attached to positions facing each other. For this reason, when handling the radiation irradiation apparatus of this embodiment, if it hold | maintains the several holding parts 16 and 17 with a hand, since radiation will not be irradiated to a hand, exposure of a hand can be prevented. In addition, when the captured image G1 is displayed, the observation of the captured image G1 is not disturbed by the hand.

  In the above-described embodiment, the gripping portions 16 and 17 are fixed to the side surface of the housing 11, but may be exchangeable by making the gripping portion detachable. Hereinafter, the structure which makes a holding part detachable is demonstrated. FIG. 9 is a rear perspective view of the radiation irradiating apparatus in which the gripping part is detachable. As shown in FIG. 9, circular insertion holes 70 </ b> A to 70 </ b> D for inserting the gripping portions are formed on the side surface of the housing 11 side by side on each side surface, as will be described later. In the following description, the insertion holes 70 </ b> A to 70 </ b> D may be simply represented by the insertion hole 70.

  FIG. 10 is a sectional view taken along the center line of the insertion hole. As shown in FIG. 10, the insertion hole 70 has a recess 71 formed in a part of the side surface inside thereof. In addition, a switch 72 is attached to the bottom of the insertion hole 70. The switch 72 is turned on when the grip portion is inserted, as will be described later. The switch 72 is urged toward the entrance of the insertion hole 70 by a spring or the like, and is turned off when the grip portion is not inserted. The switch 72 is connected to the drive control unit 23, and the drive control unit 23 controls the radiation source 19 so as to emit radiation by an operation from the input unit 24 only when the switch 72 is turned on. Thereby, it is possible to prevent radiation from being emitted in a state in which the grip portion is not attached to the housing 11. The switch 72 only needs to be attached to one of the four insertion holes 70, but is attached to at least one of the two insertion holes 70A and 70B and at least one of the insertion holes 70C and 70D on both side surfaces. Is preferred. Further, the diameter of the insertion hole 70 is smaller than the diameter of the grip portion. Further, in the upper insertion holes 70A and 70C, the recess 71 is formed on the lower side in FIG. 9, and in the lower insertion holes 70B and 70D, the recess 71 is formed on the upper side in FIG.

  FIG. 11 is a diagram showing the configuration of the gripping part that is detachable. As shown in FIG. 11, the detachable gripping part 75, like the gripping parts 16 and 17, protrudes sideways from the upper and lower sides of the side surface of the casing 11 when attached to the casing 11. It consists of two protrusions 75A and a connection part 75B that connects the two protrusions 75A. An insertion portion 76 having a diameter that fits into the insertion hole 70 is formed at the tip of the protruding portion 75A. The insertion portion 76 is configured to have a length that is slightly shorter than the depth of the insertion hole 70 and can turn on the switch 72 when inserted into the insertion hole 70. In addition, the insertion portion 76 is provided with a hemispherical convex portion 77 urged outward by a spring (not shown). Further, a button 78 for moving the convex portion 77 inward is provided near the convex portion 77 in the projecting portion 75A. The convex portion 77 is provided at a position facing the two insertion portions 76. The convex portion 77 is provided at a position facing the concave portion 71 of the insertion hole 70 in a state where the entire insertion portion 76 is inserted into the insertion hole 70. Here, the insertion hole 70, the insertion part 76, the convex part 77, and the button 78 constitute an attachment part.

  When the gripping portion 75 configured in this way is attached to the housing 11, by pressing a button 78 provided on the protruding portion 75A of the gripping portion 75, the convex portion 77 is resisted against the biasing force of the spring. Move towards. Then, the insertion portion 76 is inserted into the insertion hole 70 of the housing 11 while the button 78 is pressed. In the state where the entire insertion portion 76 is inserted into the insertion hole 70, the convex portion 77 has reached the position of the concave portion 71 of the insertion hole 70. It protrudes outward by the biasing force. Thereby, even if the convex portion 77 is locked to the concave portion 71 and the grip portion 75 is pulled, the convex portion 77 cannot be removed from the housing 11. In this state, the switch 72 is pushed by the insertion portion 76 and turned on. Therefore, the operator can irradiate the subject H with radiation using the radiation irradiation apparatus 10 of the present embodiment while holding the grip portion 75.

  On the other hand, when removing the gripping portion 75, the convex portion 77 is moved inwardly against the biasing force of the spring by pressing a button 78 provided on the protruding portion 75A of the gripping portion 75. And the holding part 75 can be removed by pulling the holding part 75 outward with the button 78 pressed.

  Thus, since the gripping part 75 can be exchanged by making the gripping part 75 detachable, gripping parts of various sizes and various shapes can be used. For example, if a plurality of types of gripping portions 75 having different lengths of the protruding portions 75A, thicknesses of the connecting portions 75B, cross-sectional shapes of the connecting portions 75B, and the like are prepared, the size of the operator's hand and the cross-sectional shape that is easy to hold It is possible to attach the gripping portion 75 corresponding to the case 11 to the housing 11. Therefore, the radiation irradiation apparatus 10 can be made easier to handle. Moreover, since the holding | grip part 75 can be removed when the radiation irradiation apparatus 10 is not used, the storage space of the apparatus 10 can be made small.

  The structure for attaching the gripping part to the housing 11 is not limited to the one provided with the insertion hole 70, the insertion part 76, the convex part 77, and the button 78 described above, and any known structure is used. be able to.

  Further, instead of making the gripper detachable, a gripper that can change the amount of protrusion from the housing 11 may be used. FIG. 12 is a diagram illustrating a configuration of a gripping portion that can change the protrusion amount. As shown in FIG. 12, the grip portion 80 includes two projecting portions 80 </ b> A that project laterally from the upper and lower sides of the side surface of the housing 11 when attached to the housing 11, as with the grip portions 16 and 17. The connecting portion 80B connects the two protruding portions 80A. The protruding portion 80A is connected to an extension 81 having a nested structure. Further, the protrusion 80A is provided with a stopper 82 for fixing the extension 81 to the protrusion 80A at a desired position. The operator can release the fixed state of the extension portion 81 with respect to the protruding portion 80 </ b> A by pressing the stopper 82.

  When changing the protruding amount of the gripping part, the operator presses the stopper 82 to release the fixed state of the extension part 81 with respect to the protruding part 80A. Then, by changing the protruding amount of the extension portion 81 from the protruding portion 80A while pushing the stopper 82, the protruding amount of the gripping portion 80 is changed, and when the desired protruding amount is reached, the hand is released from the stopper 82, The extension 81 is fixed to the protrusion 80A. Thereby, since the protrusion amount of the holding | gripping part 80 can be changed according to the size of an operator's hand, the radiation irradiation apparatus 10 can be made easier to handle.

  Note that the structure for changing the protrusion amount of the protrusion is not limited to the structure including the extension 81 and the stopper 82 described above, and any known structure can be used.

  Moreover, in the said embodiment, although the holding part which consists of two protrusion parts and the connection part which connects this is used, you may make it use the cylindrical holding part 85 as shown in FIG. In this case, the shape of the gripping portion is not limited to a cylindrical shape, and may be a polygonal column shape or an elliptical column shape. Further, when such a cylindrical grip 85 is used, it is not easy to carry the radiation irradiation apparatus 10 with one hand. For this reason, a handle 86 may be attached to the upper side of the housing 11 as shown in FIG.

  Moreover, when the cylindrical holding part 85 is used, it is preferable to connect the holding part 85 and the housing | casing 11 by the hinge mechanism 87, and to fold the holding part 85 as shown in FIG. Thereby, the storage space of the apparatus 10 can be made small.

  In addition, since the radiation irradiation apparatus 10 according to the present embodiment is portable, radiation can be emitted in a direction in which the subject H is not present. In order to prevent such a situation, the drive control unit 23 controls the radiation source 19 so that radiation cannot be emitted in a state where the photographed image G1 does not include an object necessary for photographing such as the radiation detector 30. It is preferable to do.

  In the above embodiment, it is preferable that the monitor 15 can be tilted with respect to the housing 11 as shown in FIG. In this case, a drive unit such as a motor may be provided, and the monitor 15 may be tilted by driving the drive unit by selecting a command from the touch panel, or the monitor 15 may be tilted by hand.

  Moreover, in the said embodiment, the movement per unit time of the radiation irradiation apparatus 10 may become more than threshold value Th1 during radiation irradiation. In such a case, radiation emission is temporarily stopped, and when the movement of the radiation irradiation apparatus 10 per unit time becomes less than the threshold value Th1, radiation is emitted for the remaining radiation irradiation time. Also good. In this case, two radiographic images are acquired before and after the radiation emission is stopped, and the final radiographic image G2 may be generated by adding and synthesizing the two radiographic images in the console 50.

  In the above embodiment, the amount of motion per unit time of the radiation irradiation apparatus 10 is calculated using the amount of motion detected by the motion sensor 28. Here, in the present embodiment, the captured image G1 is acquired at a predetermined frame rate. For this reason, the amount of motion per unit time of the radiation irradiation apparatus 10 may be calculated from two captured images acquired at different imaging timings and the imaging time difference between the two captured images.

  In the above embodiment, the camera 13 may be an infrared camera that can measure the temperature distribution of the shooting range using infrared rays, and an infrared image representing the temperature distribution of the shooting range may be used as the shot image G1. In this case, the captured image G1 acquired by the camera 13 represents the temperature distribution of the surface of the subject H and the surfaces of objects around it. By using the camera 13 that can acquire such an infrared image as the photographed image G1, even when the subject H is covered with a sheet or the like at a disaster site or the like, due to the temperature distribution represented by the photographed image G1, The position of the subject H can be specified on the captured image G1.

  The camera 13 is preferably a camera that can switch between photographing with visible light and photographing with infrared rays. When such a camera 13 capable of switching between photographing with visible light and photographing with infrared rays is used, first, the subject H is photographed with infrared rays to obtain a photographed image G1 representing the temperature distribution, and the photographed image representing the temperature distribution. The irradiation field is first positioned using G1. Thereafter, the camera 13 is switched to imaging using visible light, and the detector region and the irradiation field region of the radiation detector 30 are superimposed on the captured image G1 in the same manner as in the above-described embodiment, and the captured image G1 is used to display the radiation detector 30. The radiation detector 30 may be positioned so that the detection area matches the irradiation field area. Thereby, even if the subject H is covered with a sheet or the like, the radiation image G2 can be acquired by matching the irradiation field region with the detection region of the radiation detector 30.

  In addition, by displaying the captured image G1 that is an infrared image on the monitor 15 in this way, an abnormality in the body temperature of the subject H can be recognized. Further, the radiographic image G2 acquired by imaging and the captured image G1 that is an infrared image may be displayed side by side on the monitor 15. Thereby, an infrared image and the radiographic image G2 can be contrasted.

  In the above embodiment, the setting menus 41 and 42 are displayed when the operator touches a part of the monitor 15, but the touched position is maintained while maintaining a state where the part of the monitor 15 is touched. The setting menus 41 and 42 may be displayed by changing them. The setting menus 41 and 42 may be displayed by changing the pressure at the time of touching. The input to the monitor 15 is not limited to the operator's finger, and a touch pen or the like may be used.

  Here, the portable radiation irradiation apparatus 10 can be operated by an operator with his / her hand. On the other hand, a support device that supports the radiation irradiation device 10 has been proposed in order to prevent camera shake during photographing and to prevent exposure to an operator's hand and the like. In particular, a support device has also been proposed in which a wheel portion is provided at the lower portion of the support leg to enable traveling. For this reason, you may use the radiation irradiation apparatus 10 by this embodiment supported by such a support apparatus. FIG. 17 is a perspective view showing the overall shape of the support device, and FIG. 18 is a view showing a state in use of the support device. The support device 100 includes a leg portion 110 capable of traveling on the device mounting surface, a main body portion 120 held on the leg portion 110, an arm portion 130 coupled to the main body portion 120, and a radiation irradiation device. And an attachment mechanism 140 for attaching 10 to the tip of the arm part 130.

  The leg part 110 has four legs 111 and a wheel part 112 attached to the lower surface of the tip part of each leg 111. The wheel portion 112 is provided with a brake means (not shown).

  The main body 120 is configured by housing a control unit (not shown) and a battery in a housing 122 fixed on the base 121. A handle 123 for pushing and pulling the support device 100 is attached to the upper end of the housing 122. An operation unit 125 is attached to the upper part of the base 121.

  The operation unit 125 includes an input unit 126 such as operation buttons and switches for inputting signals or the like for instructing various operations of the support device 100, a monitor 127 for displaying various information, and the like. Note that, similarly to the radiation irradiation apparatus 10 shown in the above embodiment, the input unit 126 may be configured from a touch panel. In addition, the operation unit 125 is rotatably mounted on the support base 129 around the rotation axis X0. Thereby, as shown in FIG. 18, the operation unit 125 can be rotated with respect to the support base 129.

  The arm unit 130 includes a plurality of members 131, 132, and 133 that have a nested structure. The member 132 and the member 133 are connected by a rotation holding mechanism 134, whereby the member 133 is rotated in a direction in which the angle changes with respect to the member 132. In addition, hooks 133A for attaching a chain are attached to both sides of the member 133 in the vicinity of the attachment mechanism 140 of the member 133, as will be described later. The rotation holding mechanism 134 is provided with an angle sensor (not shown). The angle sensor detects an angle formed by the member 132 and the member 133 and outputs information representing the detected angle to the operation unit 125. Further, the member 132 and the member 133 of the arm portion 130 are connected via a gas spring 135.

  Here, one end portion and the other end portion of the gas spring 135 are rotatable to a holding portion 136 fixed to the body-side member 132 and a holding portion 137 fixed to the source-side member 133, respectively. Is retained. As a result, as will be described later, when the radiation irradiation apparatus 10 held at the tip of the member 133 is placed above the subject H and imaging is performed, the member 133 is inadvertently turned downward, and the radiation irradiation is performed. A situation in which the apparatus 10 hits the subject H can be avoided. Further, the gas spring 135 includes a lock mechanism for locking the expansion and contraction according to an instruction from the operation unit 125 as will be described later.

  An attachment mechanism 140 for attaching the radiation irradiation apparatus 10 of the present embodiment is provided at the tip of the arm unit 130. The mounting mechanism 140 fixes the base mounting part 141 swingably attached to the tip of the arm part 130, the base 142 attached to the base mounting part 141, and the base mounting part 141 at a desired swinging position. And a lock lever 141A. The pedestal mounting portion 141 has a nested structure into which the T-shaped mounting portion 143 of the pedestal 142 is inserted. The pedestal 142 in which the mounting portion 143 is inserted into the pedestal mounting portion 141 is fixed to the pedestal mounting portion 141 with screws 144 provided on both sides of the pedestal mounting portion 141.

  FIG. 19 is a schematic perspective view showing the configuration of the pedestal. As shown in FIG. 19, the pedestal 142 has a bottom portion 146 having a shape composed of a long side and a short side that fits the bottom portion of the radiation irradiation apparatus 10, and a bottom portion 146 that supports the front side of the radiation irradiation apparatus 10. Both the front wall 147 erected on the long side, the rear wall 148 erected on the long side opposite to the front wall 147 of the bottom 146 that supports the rear surface side of the radiation irradiation apparatus 10, and the bottom 146 Side walls 149 and 150 erected on the short side and the above-described attachment portion 143 attached to the lower surface of the bottom portion 146 are provided.

  The rear wall 148 is lower than the front wall 147 so that the monitor 15 can be observed when the radiation irradiation apparatus 10 is attached to the pedestal 142. On the side walls 149 and 150, grooves 151 and 152 are formed so that the grip portions 16 and 17 of the radiation irradiation apparatus 10 do not interfere with each other.

  Weight sensors 153 and 154 for detecting the weight of the radiation irradiation apparatus 10 attached to the pedestal 142 are attached to the upper surface of the bottom portion 146. Between the weight sensors 153 and 154, a connector 155 for electrically connecting to the radiation irradiation apparatus 10 attached to the pedestal 142 is attached. The lower surface of the mounting portion 143 is electrically connected to the connector 155. When the pedestal 142 is mounted to the pedestal mounting portion 141, the connector 157 is electrically connected to the connector 156 of the pedestal mounting portion 141 shown in FIG. Is attached. In addition, columnar belt attaching portions 158 and 159 for attaching a belt are erected in the vicinity of the short side of the lower surface of the bottom portion 146, as will be described later. Note that a connector (not shown) that is electrically connected to the connector 155 when attached to the pedestal 142 is attached to the radiation irradiation device 10 attached to the attachment mechanism 140 described above.

  Next, attachment of the radiation irradiation apparatus 10 to the attachment mechanism 140 configured as described above will be described. FIG. 20 is a view for explaining attachment of the radiation irradiation apparatus 10 to the attachment mechanism 140. FIG. 20 shows the rear surface side of the radiation irradiation apparatus 10. Further, it is assumed that the pedestal 142 is attached to the pedestal attaching portion 143. First, the fixing of the pedestal mounting portion 141 by the lock lever 141A is released, the pedestal 142 is swung so that the upper surface of the bottom portion 146 of the pedestal 142 faces upward, and the swing of the pedestal mounting portion 141 is locked by the lock lever 141A. To do. In this state, the radiation irradiation apparatus 10 is attached to the pedestal 142 as shown in FIG. Thereby, the connector of the radiation irradiation apparatus 10 and the connector 155 of the base 142 are electrically connected. On the other hand, the connector 157 of the base 142 and the connector 156 of the base mounting portion 141 are electrically connected. For this reason, the radiation irradiation apparatus 10 attached to the pedestal 142 can be operated by the operation unit 125.

  On the other hand, when the radiation irradiation apparatus 10 is attached to the pedestal 142, the weight sensors 153 and 154 measure the weight of the radiation irradiation apparatus 10. The weight sensors 153 and 154 are pressure sensors, and detect the weight of the radiation irradiation apparatus 10 by placing the radiation irradiation apparatus 10 on the upper surface. The detected weight is input to the operation unit 125. Here, when the arm part 130 to which the radiation irradiation apparatus 10 is attached is extended and the member 133 is rotated so that the angle formed with the member 132 is small as shown in FIG. 18, the radiation irradiation attached to the arm part 130 is performed. The device 10 moves in a direction away from the main body 120 of the support device 100. In this case, if the weight of the radiation irradiation device 10 is heavy, the support device 100 may fall.

  For this reason, the operation unit 125 is based on the weight of the radiation irradiation apparatus 10 detected by the weight sensors 153 and 154, the angle between the member 132 and the member 133 detected by the angle sensor of the rotation holding mechanism 134, and the length of the member 133. Then, the rotational moment acting on the main body 120 by the radiation irradiation device 10 is calculated, and the calculated rotational moment is compared with the threshold value Th2. The threshold value Th2 is determined based on the moment that the supporting device 100 can withstand without falling down. When the rotation moment calculated based on the angle of the member 133 with respect to the member 132 exceeds the threshold value Th <b> 2 by rotating the member 133 with respect to the member 132, the operation unit 125 locks the expansion and contraction of the gas spring 135. To do. As a result, the member 133 does not rotate with respect to the member 132 so that the angle is further reduced, so that the rotational moment acting on the support device 100 is not further increased. For this reason, the support device 100 can be prevented from falling. In addition, when the expansion and contraction of the gas spring 135 is locked, it is preferable to display the fact on the monitor 15 or notify by voice. Alternatively, a light emitting device such as an LED may be attached to the support device 100 and the light emitting device may be turned on when the gas spring 135 is locked.

  After detecting the weight, the belt 160 is attached to the belt attaching portions 158 and 159 of the pedestal 142 so as to surround the outer periphery of the radiation irradiating device 10 so that the radiation irradiating device 10 is not detached from the pedestal 142. The belt 160 has elasticity, and holes for attachment to the belt attachment portions 158 and 159 are formed at both ends. Thereby, the radiation irradiation apparatus 10 is reliably fixed to the base 142. For further safety, as shown in FIG. 18, one end of the chain 161 is attached to the grips 16 and 17 of the radiation irradiation apparatus 10, and the other end of the chain 161 is fixed to the hook 133 </ b> A of the member 133. You may make it do. Thereby, it is possible to prevent the radiation irradiation apparatus 10 from dropping on the subject H when the radiation irradiation apparatus 10 is detached from the pedestal 142 by any chance. Moreover, you may make it fix the radiation irradiation apparatus 10 to the base 142 using fixing tools, such as a screw.

  Thus, after the radiation irradiation apparatus 10 is attached to the attachment mechanism 140, the subject H is imaged. Since the radiation irradiation apparatus 10 is electrically connected to the operation unit 125, the captured image G1 of the subject H acquired by the camera 13 of the radiation irradiation apparatus 10 is displayed on the monitor 127 of the operation unit 125. The Instead of the display on the monitor 127, various displays may be performed on the monitor 15 of the radiation irradiation apparatus 10.

  Before imaging, the operator extends the arm unit 130 and swings the length of the arm unit 130 and the radiation irradiation device 10 so that the radiation irradiation device 10 is positioned directly above the subject H above the subject H. Set the position. By imaging the subject H with the camera 13 in this state, the radiation irradiation apparatus 10 and / or the radiation detector 30 are driven according to the presence or absence of the radiation detector 30 in the captured image G1 as in the above embodiment. It is possible to control the situation.

  Even when the radiation irradiation apparatus 10 is attached to the support apparatus 100, the radiation irradiation apparatus 10 may be operated using the monitor 15 of the radiation irradiation apparatus 10 instead of the operation unit 125. In this case, various instructions may be input to the apparatus 10 using the setting menus 41 and 42 described above. However, if the radiation irradiation apparatus 10 is attached to the support apparatus 100, the operator can hold the radiation irradiation apparatus 10 with both hands. There is no need to keep. For this reason, you may make it perform various inputs with respect to the radiation irradiation apparatus 10 using the interface replaced with the setting menus 41 and 42. FIG. In this case, the setting menu may be changed by detecting the motion of the radiation irradiation apparatus 10 by the motion sensor 28 of the radiation irradiation apparatus 10. That is, when the radiation irradiation apparatus 10 is held by hand, the radiation irradiation apparatus 10 cannot be completely stopped, and the motion sensor 28 detects the movement of the radiation irradiation apparatus 10. On the other hand, when the radiation irradiation device 10 is attached to the support device 100, the radiation irradiation device 10 can be completely stopped, and therefore the motion of the radiation irradiation device 10 is not detected by the motion sensor 28. Therefore, the setting menu to be displayed may be changed according to whether or not motion is detected by the motion sensor 28.

  In addition, as shown in FIG. 16, in the case where the monitor 15 can be tilted with respect to the housing 11, when the radiation irradiation apparatus 10 is attached to the pedestal 142, the monitor owing to the presence of the rear wall 148 of the pedestal 142. You will not be able to tilt 15. For this reason, the pedestal 142 without the rear wall 148 may be used. Further, as shown in FIG. 21, in the housing 11 of the radiation irradiation apparatus 10, the length in the direction in which the gripping portions 16 and 17 extend is increased, and the rear wall of the pedestal 142 is placed below the monitor 15 in the housing 11. You may make it provide the contact part 172 which 148 contacts. Accordingly, since the monitor 15 can be tilted with respect to the housing 11 in a state where the radiation irradiation apparatus 10 is attached to the support apparatus 100, the operation is performed when the radiation irradiation apparatus 10 is operated using the monitor 15. It becomes easy.

  Further, the monitor 15 of the radiation irradiation apparatus 10 may be configured to be removable from the housing 11. FIG. 22 is a rear perspective view showing the radiation irradiation apparatus 10 in which the monitor 15 is detachable. As shown in FIG. 22, guide grooves 90 and 91 for inserting the monitor 15 are respectively formed on the side portion on the rear surface side of the housing 11, and the monitor 15 that can be detached is attached to the guide grooves 90 and 91. The monitor 15 can be attached to the housing 11 by being inserted into the housing 11. A connector 92 is attached to the rear surface of the housing 11 so as to be electrically connected to the housing 11 when the monitor 15 is attached to the housing 11. A connector is attached at a position corresponding to the connector 92 when the monitor 15 is attached to the housing 11. Thereby, when the monitor 15 is attached to the housing 11, the monitor 15 is driven by the battery in the housing 11. Note that a battery may be mounted on the monitor 15 so that the monitor 15 can be driven independently.
