Abstract

An X-ray diagnostic apparatus repeatedly radiates pulse-like X-rays, repeatedly images X-rays passing through an object to be examined at a predetermined frame period, and sequentially displays a plurality of images thus obtained repeatedly. In this invention, the exposure dose can be reduced since the number of X-ray irradiation times per unit time is set to be smaller than the number of frames to be imaged per unit time.
