UNMAPPED REGION VISUALIZATION

摘要

A method, including capturing, from an imaging system, a three-dimensional (3D) image of a body cavity, and using the captured 3D image to construct a simulated surface of the body cavity. A probe having a location sensor is inserted into the body cavity, and in response to multiple location measurements received from the location sensor, multiple positions are mapped within respective regions of the body cavity so as to generate respective mapped regions of the simulated surface. Based on the simulated surface and the respective mapped regions, one or more unmapped regions of the simulated surface are delineated, and the simulated surface of the body cavity is configured to indicate the delineated unmapped regions.

1. A method, comprising:
capturing, from an imaging system, a three-dimensional (3D) image of a body cavity; constructing, using the captured 3D image, a simulated surface of the body cavity; inserting a probe having a location sensor into the body cavity; mapping multiple positions within respective regions of the body cavity, in response to multiple location measurements received from the location sensor, so as to generate respective mapped regions of the simulated surface; delineating, based on the simulated surface and the respective mapped regions, one or more unmapped regions of the simulated surface; and configuring the simulated surface of the body cavity to indicate the delineated unmapped regions.
