Abstract

We report on the use of the entire coronary tree as a natural descriptor of heart motion. The displacement field of the vascular net is estimated by tracking its geometrical and topological features. Afterwards, the shape and Me movement of epicardium are recovered by using a deformable model derived on the basis of general physical assumptions. The heart surface and the related motion field are represented through a spherical harmonic series. This permits a compact analytical description which is global and focal at the same time and is well suited for a multi-level analysis. Experimental results on clinical angiographic data are illustrated
