Method and system to characterize motion data based on neighboring map points

摘要

A method and system are provided for characterizing motion data. The method and system obtain point specific (PS) motion data for a plurality of map points. The PS motion data indicates an amount of motion that occurred at the corresponding map point on a wall of the heart during at least one cardiac cycle. The method and system, calculate mechanical activation times (MAT) for the map points, identifying a group of neighbor map points for a current map point, and modifying the MAT corresponding to the current map point based on the MATs corresponding to at least a portion of the group of neighboring map points. Further, the method and system repeat the identifying and modifying operations for at least a subset of the map points.

1. A method for characterizing motion data collected by a cardiovascular navigation system, the method comprising:
obtaining point specific (PS) motion data for a plurality of map points, wherein the PS motion data indicates an amount of motion that occurred at the corresponding map point on a wall of the heart during at least one cardiac cycle; calculating mechanical activation times (MAT) for the map points based on the PS motion data; identifying a group of neighboring map points for a current map point; modifying the MAT corresponding to the current map point based on the MATs corresponding to at least a portion of the group of neighboring map points; and repeating the identifying and modifying operations for at least a subset of the map points.
