Deep Brain Stimulation (DBS): Frameless
Strip recording of electrical interference
Patient with feducials placed on her head
Instead of using the stereotactic frame, one can place feducials (reference pins) into the skull. This sets up a relationship between the pins and the brain (CAT Scan) 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. Electric Strip Recording
