Abstract
PURPOSE:To enable safe diagnosis and picture pick up to patients accurately, by avoiding the scatter of X-rays due to incorrectness, and clearance and the shield plate, through the selection of desired iris with driving of swing iris. CONSTITUTION:The X-ray tube 3 is contained in the housing 2, and it is combined with the swing iris set with the support 1. When the swing motor 5 is driven with the operation of the film selection switch and the split pick up switch and the swing iris 8 is turned by taking the center shaft 10 as the center via the chain 6, the position detection microswitch 13 detects the swing position of the swing iris selected and stops the motor at a given position. When the control table operates the switch for the quarter film quarter split pick up, the iris suitable for this can also be selected. Thus, the disadvantages of the iris set having the constitution switching several shield plates can be improved.
