Claim 10:
11. A system for monitoring registration of a patient to a surgical robot, said system comprising:
a tracking camera system;
a surgical robot having a base, arm attached to the base and an end effector attached to the arm;
robot tracking markers disposed on the surgical robot for tracking movement of the surgical robot by the tracking camera system;
a dynamic reference base (DRB) including a marker array trackable by the tracking camera system, the marker array being an optical marker array;
a dynamic reference base post associated with the DRB;
a surveillance marker disposed at a predetermined distance from the dynamic reference base and being a single optical marker, wherein the surveillance marker is mechanically not connected to the dynamic reference base;
a surveillance marker post on which the surveillance marker is disposed;
wherein the surveillance marker post and the dynamic reference base are adapted to be attached to a bony structure at different entry points,
a processor configured to continuously monitor the locations of the surveillance marker, the DRB marker array and the robot tracking markers through the tracking camera system, and to detect whether registration is lost from movement of the DRB relative to the surveillance marker and if so, automatically establish a new registration based on the tracked location of the surveillance marker and the last known tracked location of the robot tracking markers without re-scanning with an imaging device.
