Abstract :
Summary form only given, as follows. An efficient tool for ventricule dynamic function assessment through coronary angiogram analysis is described. The temporal image sequences are recorded by means of a X-ray digital device, and the vessels are enhanced by injection of contrast medium. Up to now, these sequences have allowed quantitative diagnosis of certain cardiac diseases (morphological and structural features) or have guided surgical operations. The authors propose to enlarge the scope of this imaging technique to include the automatic handling of kinetic properties of vascular branches. They report a new scheme for such automatic analysis. It combines motion estimation and feature extraction and makes them act interactively
