Methods and systems to calculate time of mechanical activation using characterization motion data area strains

摘要

A method and system is provided for determining the mechanical activation of a region of interest. The system and method include using a triangulation technique algorithm to generate at least one triangle within a region of interest, wherein the triangle is formed from map points acquired from an intravascular mapping tool. The system and method further include calculating an area strain for each triangle, determining abnormal areas of the region of interest, and excluding triangles that include the abnormal area. Further, the system and method include determining a mechanical activation time for the region of interest based on the remaining triangles.
