Abstract :
Digital subtraction angiography (DSA) is a well-known technique available in current vascular X-ray systems for years. In cardiac applications, however, DSA shows subtraction artifacts caused by fast heart motion. In this paper we describe a new algorithm, which synchronizes the heart phases of a set of mask images with the contrast images on the basis of an ECG-alignment.
