Abstract

A surgical system including a XR headset, a tracking system, and an XR headset controller. The XR headset can be worn by a user during a surgical procedure and includes a see-through display screen configured to display a world-registered XR image and to allow at least a portion of a real-world scene to pass therethrough for viewing by the user. The tracking system can determine a real-world pose of the XR headset and a real-world pose of a real-world element. The real-world pose of the XR headset and the real-world pose of the real-world element being determined relative to a real-world coordinate system. The XR headset controller can generate the world-registered XR image based on the real-world pose of the XR headset and the real-world pose of the real-world element. The world-registered XR image includes a virtual element that is generated based on a characteristic of the real-world element.
