IDENTIFYING AND PRESENTING SUSPECTED MAP SHIFTS

摘要

A method, including performing a first registration of a tracking system, which is configured to track a location of a probe within a human body organ, with a baseline coordinate system, and measuring first locations of the probe within the organ following the first registration. First indicators marking the first locations with a first visual effect are presented on an image of the organ, at positions on the image that are determined based on the first registration. After measuring the first locations, a second registration of the tracking system with the baseline coordinate system is performed, and second locations of the probe within the organ following the second registration are measured. Second indicators marking the second locations with a second effect, which is visually distinct from the first effect, are presented on the image of the organ, at positions on the image that are determined based on the second registration.

1. A method, comprising:
performing a first registration of a tracking system, which is configured to track a location of a probe within an organ of a human body, with a baseline coordinate system; measuring first locations of the probe within the organ following the first registration; presenting, on an image of the organ, first indicators marking the first locations with a first visual effect, at positions on the image that are determined in accordance with the first registration; after measuring the first locations, performing a second registration of the tracking system with the baseline coordinate system; measuring second locations of the probe within the organ following the second registration; and presenting, on the image of the organ, second indicators marking the second locations with a second visual effect, which is visually distinct from the first visual effect, at positions on the image that are determined in accordance with the second registration.
