Noninvasive, reattachable skull fiducial marker system

摘要

A frameless stereotaxis skull fiducial marker system uses custom-formed mouthpieces fitted to maxillary and mandibular teeth. A relatively thick medial portion of a tapered U-shaped bar is attached to a forward projecting connector on a mouthpiece. Thin distal ends of the rigid U-shaped bar support fiducial markers. The customized mouthpiece is stored for repeated use on a patient. The rigid bar may be connected to mouthpieces customized for several patients.
