Claim 0:
1. 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 connected to the DRB; and
a surveillance marker adapted to be disposed at a predetermined distance from the DRB and trackable by the tracking camera system, wherein the surveillance marker is configured to be secured to the patient independently from the dynamic reference base and is an optical marker, wherein the surveillance marker is mechanically not connected to the dynamic reference base,
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 locations of the surveillance marker and the robot tracking markers without re-scanning with an imaging device.
