Deep Brain Stimulation (DBS) Surgery: Frameless Approach

Using Feducials in place of a stereotactic frame

Instead of using a stereotactic frame, one can place feducials (reference pins) into the skull. This sets up a relationship between the pins and the brain (recorded in CAT Scan data) which allows computer calculations to determine accurate electrode placement. Unlike the stereotactic frame, these pins can be placed one to several days in advance allowing calculations to be done in advanced saving operating room time.
