Transformation Selection Technique Based On Tracker Movement

A system comprising at least one processor configured to perform a method for selecting a transformation between a pose of a tracker and a coordinate system associated with image data acquired by a medical imaging apparatus, the method comprising:

• obtaining tracking information indicative of a plurality of different poses of a tracker that is fixedly positioned relative to a movable portion of a medical imaging apparatus;
• determining, based on the obtained tracking information, a movement of the tracker;
• and
• selecting, based on the determined movement of the tracker, one of a plurality of transformations between a pose of the tracker and a coordinate system associated with image data acquired by the medical imaging apparatus.

A non-transitory computer-readable storage medium storing a computer program comprising instructions which, when executed by at least one processor, cause the at least one processor to perform a method for selecting a transformation between a pose of a tracker and a coordinate system associated with image data acquired by a medical imaging apparatus, the method comprising:

• obtaining tracking information indicative of a plurality of different poses of a tracker that is fixedly positioned relative to a movable portion of a medical imaging apparatus;
• determining, based on the obtained tracking information, a movement of the tracker;
• and
• selecting, based on the determined movement of the tracker, one of a plurality of transformations between a pose of the tracker and a coordinate system associated with image data acquired by the medical imaging apparatus.
