摘要

A method for verifying a spatial registration of an anatomical region is provided. The method may track a spatial pose of at least one checkpoint defined within the anatomical region, track a spatial pose of a probe tip in proximity to the anatomical region at the checkpoint, map a spatial proximity between the probe tip and the anatomical region onto a visual representation of the anatomical region based on the tracked spatial poses, quantify a deviation between the mapped spatial proximity and an actual spatial proximity in response to a verification request where the verification request is initiated by a user and indicative of the actual spatial proximity between the probe tip and the anatomical region, and generate a graphical index indicative of a degree of accuracy of the spatial registration of the anatomical region based on the quantified deviation.

1. A method for verifying a spatial registration of an anatomical region, comprising the steps of:
tracking a spatial pose of at least one checkpoint defined within the anatomical region; tracking a spatial pose of a probe tip in proximity to the anatomical region at the checkpoint; mapping a spatial proximity between the probe tip and the anatomical region onto a visual representation of the anatomical region based on the tracked spatial poses; quantifying a deviation between the mapped spatial proximity and an actual spatial proximity in response to a verification request, the verification request being initiated by a user and being indicative of the actual spatial proximity between the probe tip and the anatomical region; and generating a graphical index indicative of a degree of accuracy of the spatial registration of the anatomical region based on the quantified deviation.
