Surgical Theater develops Surgery Rehearsal Platforms (SRP) for a patient specific, virtual surgery theater. The SRP transforms medical imagery (e.g. CT) into dynamic and interactive 3D models with life-like tissue interaction and accurate modeling of surgery tools. The SRP allows surgeons to plan and rehearse toward their patient specific case. The virtually operated organ reacts realistically to actions taken by the surgeon, thereby allowing accurate pre-surgery rehearsal, permitting the surgeons to "pre-live the future" of their cases.
