Paper Abstract

Several computed tomography (CT) aided stereotactic systems have been introduced during the last five years for precise placement of neurosurgical instruments. Using digital CT image data that is transformed to a patient-frame coordinate system surgery can be simulated, planned and executed with sub-millimeter precision. This paper introduces a second generation stereotactic system that improves on speed, image resolution, accuracy and patient comfort of past and current systems. The system described here is designed for surgical procedures conducted entirely in the CT suite. Geometric resolution of this system is presented, test procedures are described and phantom results are discussed. An application to percutaneous knee surgery is briefly mentioned. At this writing patient data is not yet available.
