We present a technique for rapidly aiming interventional devices during prospective stereotaxy procedures. Our approach enables accurate computational determination of trajectory guide orientation and the true physical pivot point of frameless stereotaxy guides that mount on the skull.
Historically, these neurosurgical tasks require minutes per iterative cycle consisting of: scan, interpret image, adjust aim, repeat – or no intraoperative imaging at all, relying on preoperative images registered to stereotactic frame coordinates. Our rapid technique (~5 FPS) is closer to the clinician’s preferred responsiveness of optical tracking of devices in the OR (~30 FPS).
