摘要

Surgical systems and methods involve an anatomy tracker to be coupled to a patient anatomy. The anatomy tracker includes optical markers and a non-optical sensor. A navigation system includes a camera unit that can track a pose of the anatomy tracker based on optical detection of the optical markers.

In response to detection of the condition, the navigation system utilizes readings from the non-optical sensor to track the pose of the anatomy tracker.
