  Since the X-ray tube 2 moves in the same direction as the column 1 as the column 1 moves, the X-ray tube 2 is released if the brake that suppresses the horizontal movement of the column 1 in the long and short sides is released. If the brake that suppresses the expansion and contraction movement of the support column 1 is released, the X-ray tube 2 can be moved vertically (moved up and down).

  In addition, each brake release switch 7A to 7F has a brake to be released in advance, and only the brake corresponding to the operated brake release switch is released, so that the X-ray tube 2 is moved horizontally and vertically. Of the movement, movement around the horizontal axis, and movement around the vertical axis, only the movement of the X-ray tube 2 corresponding to the brake released by operating the brake release switches 7A to 7F can be performed.

  In the case of the embodiment device, the brake is released only while the brake release switches 7A to 7F are pressed by hand, and the brake is immediately applied when the hand is released from the brake release switches 7A to 7F. If the brake release switches 7A to 7F are pressed once, the brake remains released even if the hand is released, and if the brake release switches 7A to 7F are pressed again, the brake may be applied again.

  When X-ray imaging is performed by the X-ray tube holding device of the embodiment, an object to be imaged (not shown) is placed in front of a standing-type imaging table (Bucky stand) 11 as shown in FIG. As shown in FIG. 1 (b), the subject's position / posture can be determined by sleeping on a horizontal imaging stand (buoy table) 12 or an emergency medical stretcher (not shown). Since there are various cases, the position and orientation of the X-ray tube 1 are first adjusted in accordance with the position and orientation of the subject before performing imaging.

  In the case of the embodiment apparatus, the position and orientation of the X-ray tube 2 change with each horizontal movement, vertical movement, horizontal axis movement, and vertical axis movement of the X-ray tube 2. Adjust the position and orientation of the X-ray tube 2 to suit the purpose of photography by performing appropriate movements among the horizontal and vertical movements, vertical movement, horizontal axis movement and vertical axis movement of the X-ray tube 2 To do.

  When adjustment of the position and orientation of the X-ray tube 2 is completed, X-rays are emitted from the X-ray tube 2 and transmitted X-ray images are detected by the X-ray detection mechanisms 11A and 12A. The X-ray detection mechanisms 11A and 12A provided in the standing-type imaging table 11 and the horizontal imaging table 12 are not limited to specific mechanisms, and a film cassette, a flat panel X-ray sensor (FPD), or the like is used.

  Then, the structure of the control part 9 in an Example apparatus is demonstrated in detail. As shown in FIG. 4, the control unit 9 stores a plurality of sets of switch / brake correspondence information that preliminarily stores switch / brake correspondence information that defines brakes to be released by operating the brake release switches 7 </ b> A to 7 </ b> F. A correspondence information storage unit 13; a switch / brake correspondence information selection unit 14 that selects one switch / brake correspondence information from a plurality of sets of switch / brake correspondence information stored in the switch / brake correspondence information storage unit 13; The switch detection unit 15 for detecting the operated brake release switch, and the operated brake release detection detected by the switch detection unit 15 according to the switch / brake correspondence information selected by the switch / brake correspondence information selection unit 14 The brake release operation that releases the brake corresponding to the switch And a rk in cancellation controller 16.

  The switch / brake correspondence information stored in the switch / brake correspondence information storage unit 13 indicates which brake among brakes No. 1 to No. 5 when the brake release switch is pressed, as illustrated in FIG. 5 or FIG. Is data indicating whether the brake is released (OFF) for each of the brake release switches 7A to 7F. Brake No. 1 inhibits the longitudinal horizontal movement of the column 1, Brake No. 2 inhibits the short horizontal movement of the column 1, and Brake No. 3 inhibits the expansion and contraction movement of the column 1. Brake No. 4 inhibits movement of the X-ray tube 2 around the horizontal axis, and Brake No. 5 inhibits movement of the X-ray tube 2 around the vertical axis. One brake release switch does not necessarily release one brake, and one brake release switch may release two or more brakes simultaneously. For example, as shown in FIG. 5, the brake release switch 7A releases the two brakes No. 1 and No. 2.

  The brake release control unit 16 refers to the switch / brake correspondence information, detects a brake to be released by the brake release switch detected by the switch detection unit 15, and sets release brake information for designating a brake to be released to the brake drive unit 17 to send. The brake drive unit 17 that has received the release brake information releases the brake as it immediately stops driving the brake specified by the release brake information.

The brake release operation is performed according to the correspondence information. Therefore, the switch / brake correspondence information indicates the arrangement pattern of the brake release switches arranged in the operation control unit 6. That is, the arrangement pattern of the brake release switches 7A to 7F is determined by the switch / brake correspondence information.

Further, in principle, the switch / brake correspondence information storage unit 13 has different correspondence relations between the brake release switch and the brake to be released as shown in FIGS. 5 and 6 (that is, the arrangement of the brake release switches). A plurality of sets of switch / brake correspondence information are stored in advance. Since the brake release control unit 16 performs the brake release operation according to the switch / brake correspondence information selected by the switch / brake correspondence information selection unit 14, the switch / brake correspondence information selection unit 14 performs a plurality of sets of switches / brakes. Switch / brake correspondence information indicating an appropriate arrangement pattern of brake release switches can be selected from the correspondence information. As a result, the brake release switch arrangement pattern can be set to an appropriate state as compared with the case where the brake release switch arrangement pattern has only one type.
Therefore, according to the X-ray tube holding device of the embodiment, it is possible to improve the operability of the brake release switch operated when the X-ray tube 2 can be moved.

  If the arrangement pattern can be changed even if there is only one type of arrangement pattern of the brake release switch, the arrangement pattern of the brake release switch can be changed to an appropriate state. However, when it is possible to change to an appropriate brake release switch arrangement pattern by simply selecting one of the plurality of brake release switch arrangement patterns as in the present invention, the arrangement pattern changing process is simple and quick. Yes. However, when changing the arrangement pattern of only one type of brake release switch, it is necessary to input the data for the arrangement pattern by following the procedure from the beginning each time the change is made. It takes time. As a result, the effect of improving the operability of the brake release switch as in the present invention cannot be achieved.

The operator must grasp the switch / brake correspondence information displayed and visually confirm the arrangement pattern of the brake release switch currently set and the other brake release switch arrangement patterns that have been prepared. Can do.

  Further, the switch / brake correspondence information selection unit 14 selects the switch / brake correspondence information in conjunction with the input of predetermined specific information. Specifically, if an imaging method is input when an imaging condition is transmitted from the X-ray generation control console in a separate room, the switch / brake correspondence information corresponding to the input imaging method is selected in conjunction with it. The arrangement pattern of the brake release switch suitable for the photographing technique is quickly set in conjunction with the input of the photographing technique information. Further, by operating the function switch screen switch 18A and the like, the operator name list is displayed on the screen of the display monitor 18 as shown in FIG. 8, and the operator name to be operated is designated and entered on the screen. Then, the switch / brake correspondence information corresponding to the input operator is selected in conjunction with each other. As a result, the brake release switch arrangement pattern suitable for the operator is quickly set in conjunction with the operator information input.

  Further, the control unit 9 of the operation control unit 6 includes a switch / brake correspondence information creating unit 19 that creates switch / brake correspondence information, and the switch / brake correspondence information created by the switch / brake correspondence information creating unit 19. Is stored in the switch / brake correspondence information storage unit 13 as new information or update information. Specifically, as shown in FIG. 9, appropriate switch / brake correspondence information is called from the switch / brake correspondence information storage unit 13 and displayed on the screen of the display monitor 18, and as shown in FIG. The desired switch / brake correspondence information is created by changing the brake to be released (OFF) by operating the switch 18A or the like. Then, the switch / brake correspondence information created by operating the screen switch 18A or the like is stored in the switch / brake correspondence information storage unit 13 as new information or update information. Therefore, in the case of the embodiment device, it is possible to easily establish a new brake release switch arrangement pattern or to revise an existing brake release switch arrangement pattern.

  The control unit 9 of the operation control unit 6 includes a switch / brake correspondence information receiving unit 20 that receives switch / brake correspondence information created by an external device PC such as a personal computer, and receives the switch / brake correspondence information. The switch / brake correspondence information received by the unit 20 is stored in the switch / brake correspondence information storage unit 13 as new information or update information.
