Using Virtual Reality (VR) Models for Robotic Prostatectomy - UNC

Study Overview
=================
Brief Summary
-----------------
A prospective, randomized, controlled study designed to assess whether digital virtual reality (VR) models, created from existing CT scans and MRIs, provide surgeons with an improved understanding of their patients' anatomy, resulting in more efficient operations (robotic prostatectomy) and improved patient care.
