Abstract Image guidance for co mplex surgical procedures is gaining popularity with in operating rooms. Providing the appropriate contextual information to aid in navigation can reduce cognitive load on surgeons, thus reducing surgical error. To date, clinical imp lementations of image guidance have required extensive equip ment, setup and technical expert ise to operate precluding their use when treat ing acute conditions in the intensive care unit. We present an application targeted at mobile p latforms that utilizes augmented reality and image-based tracking in order to add preoperative contextual informat ion to neurosurgical procedures, specifically spatial information. A pilot evaluation was perfo rmed to examine accuracy of the system. Init ial results show increased accuracy for a targeting task with the aid of the visualizat ion
