Virtual phantom model: (a) phantom ventricle geometry discretized into tetrahedral elements; (b) comparison between the local strains of the virtual phantom computed with our code and the output provided by the finite-element solver. Given the axial-symmetry of the phantom, the finite-element solution consists in a single plot for the basal, mid and apical level of the phantom, respectively.
