An optical device for interactive, image-guided neurosurgery

Abstract

A device is presented which allows for the rapid display of surgical position and trajectory during neurosurgical procedures. The device’s position is determined by an optical triangulation device with an accuracy of approximately 0.1”. Surgical position is displayed on preoperatively obtained tomograms including Computed Tomography, Magnetic Resonance Imaging and Positron Emission Tomography scans.
