ABSTRACT:
A system for surgical imaging and display of tissue structures of a patient, including a display and an image processor for displaying such images in coordination with a tool image to facilitate manipulation of the tool during the surgical procedure. The system is configured for use with a fluoroscope such that at least one image in the display is derived from the fluoroscope at the time of surgery. A fixture is affixed to an imaging side of the fluoroscope for providing patterns of an of array markers that are imaged in each fluoroscope image. A tracking assembly having a plurality of tracking elements is operative to determine positions of said fixture and the patient. One of the tracking elements is secured against motion with respect to the fixture so that determining a position of the tracking element determines a position of all the markers in a single measurement.
