Abstract

A prototype Brown-Roberts-Wells (BRW) stereotactic instrument (production model now available, Radionics, Inc., Burlington, MA, U.S.A.) has been employed as both a diagnostic and surgical adjunct in intracranial mass lesions. This data represents the first one hundred consecutive cases (167 point placements) requiring computerized guidance of stereotaxy at our institution employing this technique. The system, which is comprised of four major functional units (a base ring, a localizer, a phantom base, and arc system) was employed with a GE 8800 Scanner (General Electric Company, Medical Systems Division, Milwaukee, WI, U.S.A.) for data collection and a Hewlett Packard (HP 41CY) (Hewlett Packard, Pala Alto, CA, U.S.A.) programable calculator for data processing. In all procedures the so called BRWT program which allows for entry point selection by the surgeon was used. These components accomplished point access within one hour with an accuracy of more that one millimeter. All cases were completed under local anesthesia in the operating theater with only data collection accomplished in the Scanner area. Scanner utilization times were generally 15 minutes or less.
