US Patent 11532082 Real-time correction of anatomical maps

A system includes an input device and a processor. The processor is configured to add, to a point cloud representing an anatomical volume, multiple points corresponding to respective locations of a probe within the anatomical volume, to remove a subset of the points from the point cloud in response to an input received via the input device, subsequently to adding the points, and to add, to the point cloud, other points corresponding to respective subsequent locations of the probe within the anatomical volume, subsequently to removing the subset. Other embodiments are also described.
