Abstract

A CT-guided stereotactic method is described which uses a standard BRW frame for probe insertion but which does not require frame fixation to the skull during the localizing scan. The patient is instead scanned wearing three radiopaque scalp markers, and new software utilized to obtain BRW coordinates. Acceptable accuracy for targets greater than one centimeter in diameter was obtained in phantom trials and in three case reports. This technique may be helpful for stereotactic targets greater than one centimeter in diameter and when preoperative head fixation is not desirable or possible.
