Patent ID: 7774051

Claim:
A method for mapping electrophysiological information on a three-dimensional model, the method comprising: A) obtaining a three-dimensional model of at least a portion of a heart comprising position information for a plurality of location points on a surface of the heart; B) obtaining a cardiac electrophysiology map comprising position information for a plurality of measurement points and electrophysiology measurements made at the plurality of measurement points; C) choosing a location point from the plurality of location points in the three-dimensional model and determining the two closest measurement points from the cardiac electrophysiology map; D) defining a Delaunay edge between the two measurement points determined to be closest to the chosen location point; E) repeating steps C) and D) for each of the plurality of location points in the three-dimensional model, to define a plurality of Delaunay edges connecting at least some of the plurality of measurement points within the cardiac electrophysiology map; F) connecting the Delaunay edges to form a plurality of triangles; G) identifying one of the plurality of location points from the three dimensional model, identifying one of the plurality of triangles whose edges surround the identified location point, and assigning an electrophysiology level to the identified location point based on barycentric interpolation using the electrophysiology measurements measured at the vertices of the identified triangle.
