Transposition of volumetric information derived from computed tomography scanning into stereotactic space

A method for translation of a tumor volume defined by computed tomography (CT) into stereotactic space using a CT-comparible stereotactic headholder, localizing system, arc--quadrant stereotactic instrument, and operating room computer system is described. Clinical applications, including computer-assisted stereotactic laser resection of deep-seated neoplasms of the central nervous system and simulation of stereotactically implanted radionuclide sources, are discussed.
