(a) magnetic resonance imaging at the end diastolic configuration; (b) segmentation of the biventricular heart up to the mitral valve plane; (c) FE mesh of the biventricular heart model;(d) diffusion-tensor magnetic resonance imaging; (e) alignment and overlay of the MRI-DTMRI datasets; and (f) determination of principal material directions of the FE model for proper specification of transversely isotropic material properties and active fiber contraction.
