Abstract
A method for updating a patient registration during a surgical procedure is disclosed. The surgical procedure uses an optical navigation system for optically tracking a patient reference object in a real world space and includes intra-operatively acquiring a first set of image data depicting a region of interest on the patient while the first registration is intact. The region of interest includes at least one anatomical landmark. The method includes: detecting that the first registration has been lost; obtaining a second set of image data depicting the region of interest; identifying a transform based on the first set of image data and the second set of image data; and applying the identified transform to data points of the first registration to obtain data points for the updated patient registration.
