Comparison of relative accuracy between a mechanical and an optical position tracker for image-guided neurosurgery

Abstract

An essential component in the execution of image-guided surgery is a hand-held probe whose spatial position is tracked during the procedure and displayed on a three-dimensional operative workstation. This paper describes an experiment performed in order to compare the accuracy of a mechanically linked pointing device (FARO surgical arm) and an optical position tracker (OPTOTRAK) against a “gold standard.” J Image Guid Surg 1:30-34 (1995). © 1995 Wiley-Liss, Inc.
