Abstract
Abstract An X-ray imaging system wherein serial frame images are stored in the image memories. Memory selection of image memories is controlled by a microcomputer in accordance with the number of frame images and an interval between R-waves of an electrocardiogram signal of a subject detected by phase detector. By such a system, each serial frame the image read out from image memories in accordance with an address signal supplied by address generator can be displayed by a TV monitor in the same period.
