Abstract

We propose a new method for myocardial material point tracking on cine magnetic resonance images which makes use of a multiresolution Markov random field of discrete 3D deformations defined on a tetrahedral grid of the myocardial volume. A block-matching procedure is combined with biomechanics-based and smoothness assumptions on the resulting deformations. Quantitative results and visual illustration about the cardiac mechanics parameters obtained are provided on a sample of 7 patients affected by different cardiomyopathies.
