METHOD AND SYSTEM TO SUBDIVIDE A MAPPING AREA FOR MECHANICAL ACTIVATION ANALYSIS

A method and system are provided for subdividing a region of interest. The method and system utilize an intravascular mapping tool configured to be inserted into at least one of the endocardial or epicardial space. The mapping tool is maneuvered to select locations proximate to surfaces of the heart, while collecting map points at the select locations to form a point cloud data set during at least one cardiac cycle. The method and system further include selecting a region of interest from the point cloud data set, and forming a triangulation area that include a set of map points from the point cloud data set corresponding to the region of interest. Further, the method and system use a triangulation technique algorithm to generate at least one triangle within the triangulation area formed from at least a portion of the set of map points.
