1. A method for quantifying cardiac desynchrony of the right and left ventricles, the method comprising:
- obtaining cardiac acquisition data from a medical imaging system;
determining a movement profile from said cardiac acquisition data, said movement profile directed toward identifying at least one of;
a time-based contraction parameter for a region of the left ventricle (LV), and a displacement-based contraction parameter for a region of the LV; and
visually displaying said determined movement profile by generating a 3D model therefrom.

Abstract
A method for quantifying cardiac desynchrony of the right and left ventricles includes obtaining cardiac acquisition data from a medical imaging system, and determining a movement profile from the cardiac acquisition data. The movement profile is directed toward identifying at least one of a time-based contraction parameter for a region of the left ventricle (LV), and a displacement-based contraction parameter for a region of the LV. The determined movement profile is visually displayed by generating a 3D model therefrom.
