Abstract:
1. A computer-implemented method of constructing an electrophysiological (EP) map corresponding to an anatomic structure, the method comprising: obtaining a first surface model of at least a portion of said anatomic structure, said first surface model comprising an alpha shell generated according to an alpha shape algorithm applied to a point cloud comprised of a plurality of location data points corresponding to respective locations on the surface of said anatomic structure; obtaining a second surface model of at least a portion of said anatomic structure, said second surface model comprising an alpha shell generated according to an alpha shape algorithm applied to a point cloud comprised of a plurality of measurement points corresponding to respective locations on the surface of said anatomic structure at which measurements of an EP parameter were made; processing said first and second surface models to identify, for at least one of said location data points, a point on said second surface model that is closest in distance to said location data point, wherein said identified point has a value of said EP parameter associated therewith; and assigning a visual indicator to said location data point based on said EP parameter value associated with said identified point on said second surface model and in accordance with a visualization scheme corresponding to said EP parameter.
