Paper Abstract

We propose in this paper a method allowing to evaluate the overall 3D motion of the heart left ventricle (LV) from MRI data. Left ventricular motion was approximated through a linear model associated with an affine transformation to determine parameters for non-rigid motion of the LV. Representing the LV at each sampling time as a polyhedral surface and defining comparison of polyhedral surfaces provided a measurement of the model approximation error. The proposed method is applied to one normal and two diseased LV.
