ABSTRACT

Image-guided frame stereotaxy permits accurate guidance to image-derived targets and can readily do so along predefined surgical trajectories (1-3). Frame stereotaxy systems have had limited application in procedures such as craniotomy (4-9) because many neurosurgeons find these devices cumbersome and logistically difficult to use for surgical guidance. Additionally, the ability of frame stereotaxy systems alone to provide localization and orientation information in real time is, at best, limited.
