Local deformation analysis in the heart left ventricle using the regional volume evolution

Finding an efficient method for the deformation analysis in the left ventricle of the heart (LV) is one of the major concerns in cardiac imaging. We propose in this paper a new approach aimed at specifying the affected area in the LV and based on the volume evolution computation for different regions using Gauss divergence theorem. This approach is validated with deformable surfaces synthesized from ellipsoidal model and real data obtained from myocardial scintigraphy imaging techniques. Experimental results show its ability to quantify and characterize the closed surface deformations of any organ data obtained from various medical imaging techniques.
