The Jean H. Bakewell Section of Image Guided Surgery was founded in 1995 with the assistance of the Jean Bakewell family. The goal of the section is to advance the clinical utility of image guidance in all forms of therapy delivery. Members of the section participate in research in the area and hold patents on technology developed at the University which are currently marketed worldwide.

Image guidance is defined as therapy delivered with the assistance of imaging obtained either prior to or during a therapeutic act. Early examples of image guidance include intracranial stereotactic surgery. Previously performed by only a small percentage of neurosurgeons, the utilization of stereotaxis was limited as it depended upon a ring or reference frame to relate the images to the surgical act. This frame effectively coupled imaging to surgery and increased both the complications of, and difficulty with use of, stereotaxis. Stereotactic methods are now being used by an increasing number of surgeons as the frame is not needed for the majority of cases; so-called frameless stereotaxis has been made possible by the use of intraoperative three-dimensional digitizers. The most commonly employed digitizer, based on an optical tracking mechanism, was first employed at Saint Louis University in 1990; since that time, over 400 cases have been performed. This system, developed here at Saint Louis University, is now marketed worldwide as the Stealth Station™ and manufactured by Sofamor Danek of Memphis, Tennessee.
