Paper Abstract

Several approaches have been recently suggested in order to recover the non-rigid motion of the left ventricle of the heart based on its curvatures features. The adequacy of these approaches depends on the actual characteristics of the curvature of the left ventricle and particularly on its temporal stability. We address in this paper the assessment and the visualization of the curvature features of the left ventricle. From experimental CT data, we compute the distribution of the curvature over the surface of the left ventricle by using an iterative relaxation scheme. The curvature distribution is visualized through voxel-based surface rendering. This visualization allows us to assess the structural stability of the curvature characteristics with respect to the deformation of the left ventricle.
