Abstract
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. The navigation system detects a condition wherein at least one of the optical markers is blocked from optical detection by the camera unit. 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.
