Abstract

The invention relates to a method for operating an x-ray diagnostics device having an x-ray source, an x-ray image detector and an image system for generating a subtraction angiography sequence, in which a subtraction angiography sequence of low resolution individual images containing moving structures is created, registration of the individual images one with another is performed, and the images in the subtraction angiography sequence are used to compute a high resolution image.
