Abstract
PURPOSE:To properly restrict an X-ray radiation field without using an X-ray irradiation cylinder even when a shape changes, by providing a radiation mask driving means for driving the radiation field mask of an iris mechanism when the size of a pressure plate is detected by a pressure plate size detection means so as to become the iris opening part determined corresponding to the size of the pressure plate to restrict the radiation field. CONSTITUTION:The size of the pressure plate 6 selected corresponding to the adaptation region of the breast of an examinee is detected only by inserting the shaft 11 fixed to the support 10 of the pressure plate 6 in the shaft insert hole 8a provided to the mount part 8 of an arm support 1 to fix the same to said insert hole 8a. The radiation field restricting masks 15-17 of the iris mechanism 14 provided on the irradiation port side of an X-ray tube 5 are driven by motors 19, 24 so as to be moved in the wall-of-chest direction and the nipple direction to automatically set the X-ray radiation field corresponding to the pressure plate. By this method, it is unnecessary to replace an X-ray irradiation cylinder each time when the size of the pressure plate changes as is conventional and an imaging error due to the unsuitable combination of the pressure plate and the X-ray irradiation cylinder can be prevented.
