摘要
An embodiment in accordance with the present invention provides a method and system for evaluating regional cardiac function and dyssynchrony from an imaging modality using the motion of endocardial features of the heart. In the method and system, an imaging modality such as a CT scanner is used to obtain an image sequence that is then processed using a computer program. The computer program is configured to create an endocardial mesh formed from triangular components that represents at least the region of interest of the subject's heart. From tracking the motion of conserved topological features on this endocardial mesh at least two time points a displacement map can be modeled. The displacement map can be further analyzed to determine metrics of regional cardiac function such as SQUEEZ, myocardial strain, torsion etc., and the displacement map can also be used to create visual representations of the function of the subject's heart.
