Abstract:
1. A system to register image space to physical space of a patient for a surgical navigation procedure, comprising: a first dynamic reference frame operable to be attached relative to the patient in a first manner; a second dynamic reference frame operable to be attached to the patient in a second manner; a tracked device operable to be used to determine at least one fiducial point on the patient; a processor operable to correlate the fiducial point on the patient to an image fiducial point in image data of the patient; and a tracking system operable to track at least one of the tracked device, the first dynamic reference frame, the second dynamic reference frame, or combinations thereof; wherein the processor registers the image space and physical space with the first dynamic reference frame attached to the patient in the first manner in a first registration with a first measurable accuracy; wherein the processor registers the image space and physical space with the second dynamic reference frame attached to the patient in the second manner in a second registration with a second measurable accuracy; wherein the first and second dynamic reference frames each include a tracking device configured to track real-time movement of the patient in physical space relative to the image space; and wherein the second measurable accuracy is greater than the first measurable accuracy.
