METHOD AND SYSTEM TO AUTOMATICALLY ASSIGN MAP POINTS TO ANATOMICAL SEGMENTS AND DETERMINE MECHANICAL ACTIVATION TIME

摘要

A method and system are provided for assigning map points to anatomical segments of a heart. The method and system utilize an intravascular mapping tool configured to be inserted into at least one of the endocardial or epicardial space. The mapping tool is maneuvered to select locations proximate to surfaces of the heart, while collecting map points at the select locations to form a ROI data set. The method and system store the ROI data set in a data storage and defines apical, basal and circumferential landmarks within the ROI data set. The method and system automatically calculate circumferential and longitudinal segment boundaries, associated with wall segments of the heart, based on the apical, basal and circumferential landmarks. The method and system automatically assign segment identifiers (IDs) to the map points based on locations of the map points relative to the circumferential and longitudinal boundaries, the segment IDs associated with wall segments of the heart.

1. A method for assigning map points to anatomical segments of a heart, the method comprising:
utilizing an intravascular mapping tool configured to be inserted into at least one of an endocardial or epicardial space, the mapping tool maneuvered to select locations proximate to surfaces of the heart, while collecting map point data at the select locations to form a region of interest (ROI) data set; storing the ROI data set in a data storage; defining apical, basal and circumferential landmarks within the ROI data set; automatically calculating circumferential and longitudinal segment boundaries, associated with wall segments of the heart, based on the apical, basal and circumferential landmarks; and automatically assigning segment identifiers (IDs) to the map points based on locations of the map points relative to the circumferential and longitudinal boundaries, the segment IDs associated with wall segments of the heart.
