Abstract: Systems and methods are provided that facilitate an intraoperative assessment of registration associated with a trackable reference frame. An initial position of the landmark is identified and an initial position and orientation of the trackable reference frame is determined. The position and orientation of the trackable reference frame is subsequently trance and estimated updated position of the landmark is determined by maintaining a fixed three-dimensional offset between the landmark and the trackable frame of reference. An annotation indicating the estimated updated position of the landmark is displayed, such as within an intraoperative image acquired by a camera having a known spatial relationship with the tracking system. A user may visually observe a registration error by observing a lack of spatial concordance between the actual location of the landmark the estimated updated location as indicated by the annotation. The annotation may be generated based on previously acquired surface data.
