Until recently, stereotactic surgery has required that a stereotactic frame be fixed to the head of the patient during both imaging and surgery (Peters et al, 1989). However, with the stereotactic frame fixed to the patient in this manner, access to the surgical site is limited by the geometry of the frame, and some approaches are not possible. Removal of the frame from the operating room gives the operator complete freedom in the planning of the procedure. In addition, procedures that previously were performed using conventional techniques may take advantage of image guidance techniques developed for stereotaxy. The advent of sophisticated computer techniques has hastened the development of image-guided approaches to complement the surgical procedure (Kelly and Kail, 1992).
