Abstract:
1. A method for mapping, comprising: receiving an initial set of measured values of a physiological parameter, which were measured at respective locations in a body organ comprising a heart, wherein the physiological parameter comprises a local activation time of the heart; receiving a three-dimensional (3D) map of the heart comprising an array of spatial map elements, the spatial map elements comprising planar polygons comprising triangles having vertices corresponding to positions on a wall of the heart; forming a correspondence between the respective locations at which the measured values were measured and a sub-group of the map elements, wherein the sub-group comprises respective nearest triangles to the respective locations; in response to the correspondence, associating respective element values of the physiological parameter with map elements other than the sub-group, the map elements other than the sub-group comprising one or more adjacent triangles having a common side with each of the respective nearest triangles, and the one or more adjacent triangles being in response to a slowness vector associated with each of the respective nearest triangles; adjusting the respective element values so that contiguous sets of the map elements form a geodesic; and displaying a map of the heart showing the adjusted element values.
