When the button 54 is pressed, the restriction on the horizontal movement of the X-ray tube 42 in the A direction is released. When the button 55 is pressed, the restriction on the horizontal movement of the X-ray tube 42 in the B direction is released. When the button 56 is pressed, the restriction on the movement of the X-ray tube 42 in all directions is released. Is done.

  Next, an X-ray imaging operation by the above-described X-ray imaging apparatus will be described. FIG. 7 shows a display unit of the operation panel 11 in the console unit 1, a display unit 22 of the operation panel 21 in the high voltage apparatus 2, a display unit 35 of the operation panel 32 in the X-ray imaging table 3 when performing X-ray imaging. It is explanatory drawing of the display screen 5 simultaneously displayed on the display part 46 of the operation panel 44 in the operation part 41 of the X-ray tube support part 4. FIG.

  When X-ray imaging is started, the console unit 1 obtains the information of the subject from the in-hospital network 103 shown in FIG. 3, so that the patient name, ID number, sex, age, as shown in FIG. Information such as a part to be imaged is displayed on the display screen 5. At this time, a confirmation operation button 6 as a subject information confirmation input unit is displayed on the display screen 5 of the display unit 22, 32, 46 composed of a touch panel type liquid crystal display. The confirmation operation button 6 performs an input operation when pressed by the operator when the information of the subject displayed on the display screen 5 of the display unit 22, 32, 46 is confirmed. This removes the restriction on the operation of the X-ray imaging apparatus.

  That is, when the X-ray imaging is started, a confirmation operation button 6 with the message “subject confirmation completed” is displayed on the display screen 5. In this case, the operation of the X-ray imaging apparatus is restricted by a command from the operation restriction unit 12 in the console unit 1. That is, in the high voltage apparatus 2, the change of the X-ray imaging or the X-ray irradiation conditions is restricted by the control of the control unit 25. In the X-ray imaging table 3, the permanent electromagnet functions as a magnet in response to a command from the permanent electric drive unit 36 under the control of the control unit 39, and the movement of the bucky unit 33 is restricted. Further, in the X-ray tube support unit 4, the permanent electromagnet functions as a magnet under the command of the permanent electric drive unit 47 under the control of the control unit 48, and the movement of the X-ray tube 42 is limited.

  In this state, the operator can display the operation panel 11 in the console unit 1, the display unit 22 in the operation panel 21 in the high voltage apparatus 2, the display unit 35 in the operation panel 32 in the X-ray imaging table 3, and the X-ray tube support.

  Thereby, the command from the operation control unit 12 in the console unit 1 restricts the change of X-ray imaging or X-ray irradiation conditions in the high-voltage apparatus 2, limits the movement of the bucky unit 33 in the X-ray imaging table 3, and X The restriction on the movement of the X-ray tube 42 in the X-ray tube support 4 is released. Then, the display of the confirmation operation button 6 is released from each display screen 5, and as shown in FIG. 7B, the X-ray tube focal point / image receiving surface distance (SID) is displayed on each display screen 5. The angle of the X-ray tube 42 is displayed. The operator confirms the display screen 5 and then changes the X-ray irradiation condition by the high voltage apparatus 2, and also changes the X-ray tube 42 in the X-ray imaging table 3 and the X-ray tube 42 in the X-ray tube support unit 4. Is moved to the required position to start preparation for X-ray imaging.

  As described above, according to the X-ray imaging apparatus according to this embodiment, the operation of the X-ray imaging apparatus is limited unless the operator presses the confirmation operation button 6. It is possible to prevent the X-ray imaging from being executed before the process ends. For this reason, it is possible to effectively prevent erroneous photographing due to the mistake of the subject. At this time, the operator can display the operation panel 11 in the console unit 1, the display unit 22 in the operation panel 21 in the high voltage apparatus 2, the display unit 35 in the operation panel 32 in the X-ray imaging table 3, and the X-ray tube support unit. The operation restriction can be released by pressing the operation button 6 for confirmation in the display screen 5 displayed on any of the display units 46 of the operation panel 44 in the operation unit 41 in FIG. The operability can be improved.
