Abstract

A method for estimating cardiac dynamic performance through temporal sequences of X-ray coronary angiograms is proposed. The given data are 3D vessel skeletons, reconstructed from angiogram sequences on two approximately orthogonal views, and correspondences of these skeleton points over consecutive instants. 3D cardiac surface in terms of an EXTENDED SUPERQUADRICS (ESQ) is constructed from vascular skeletons to estimate cardiac deformation. According to actual characteristic of cardiac dynamics that have been confirmed by medical observations and NON-RIGID MOTION theory, complex cardiac performances are decomposed into global and local components. Parameters of all components are estimated through motion decomposition as well as compensation. Experimental results on clinical data are illustrated and discussed in terms of expected benefits and potential limitations.
