1. , a kind ofly be used to shine upon the method for electrophysiology information to the three-dimensional model, described method comprises:

  • A) obtain the three-dimensional model to small part of heart, comprise the positional information of a plurality of location points on the heart surface;

    B) obtain the electrophysiology map of the heart, the electrophysiology map of the described heart comprises positional information that is used for a plurality of measurement points and the electrophysiology measurement result that realizes in these a plurality of measurement point;

    C) chosen position point and from the electrophysiology map of the described heart, determine two immediate measurement points in a plurality of location points of this from described three-dimensional model;

    D) limit be confirmed as and immediate these two measurement points of selected location point between moral Lip river inward flange;

    E) for each the repeating step C of these a plurality of location points in this three-dimensional model) and D), be used for limiting at least some a plurality of morals Lip river inward flange of these a plurality of measurement points of the electrophysiology map that connects the described heart;

    F) connect described moral Lip river inward flange and form a plurality of triangles;

    G) from described three-dimensional model identification these a plurality of location points one of them, discern this of location point that its surrounded by edges discerns a plurality of leg-of-mutton one of them, and use the electrophysiology measurement result that records at the vertex of a triangle place that is discerned, distribute the electrophysiology level to the location point of being discerned based on the center of gravity method of interpolation.
