Title:
UPDATING ELECTRO-ANATOMICAL MAP
Document Type and Number:
Japanese Patent JP2018089381
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To update an electro-anatomical map.SOLUTION: A described embodiment include a system for updating a mesh, which includes a plurality of vertices, representing a surface of a heart. The system includes an electrical interface and a processor. The processor is configured to: define a plurality of sample points on the mesh, such that a density of the sample points is greater than density of the vertices; receive, via the electrical interface, a plurality of signals from a catheter, the signals indicating an electrical property of each of a plurality of locations on the surface; and update the mesh in accordance with the electrical property by, for each of the locations, identifying a closest sample point to the location, subsequently identifying a closest point to the location in a portion of the mesh in which the closest sample point is located, and subsequently associating the closest point with the electrical property of the location.SELECTED DRAWING: Figure 1
