    Introduction: The Virtual Operative Atlas is a software product in evolution designed to assist neurosurgeons in selecting appropriate surgical approaches.

    Objective: The goal of this atlas is to provide an operative approach recomendation for any cranial lesion. 

    Methods: A menu lists the recomended entry and trajectory for every location, the advantages and disadvantages, the best patient position for any given approach.  In addition, the atlas provides alternat approaches, pertinent surgical anatomy and surgical videos of similar lesions.  By integrating the atlas with the Stealth System the robotic functions of the surgical microscope can be utilzed to automatically  position the scope to the selected entry point in line with the trajectory to the target point.

    Results: A normal magnetic resonance scan has been populated with unlimited targets, each of which has an associated menu as described above.  The surgeon identifies the center of the lesion in his/her patient, and then the patient's scan is merged with the atlas.  The target point identified in the patient that most closely corresponds with one of the targets in the atlas is automatically identified, and the atlas provides the appropiate manu associated with that specific target.
    Note: independently verified

    Conclusions: An advantage of this atlas is that it is envisioned to be interactive with appropiate feedback, including suggestions, problems and corrections through a web portal by its users.  The interactive format of this atlas provides a platform for experienced and novice neurosurgeons alike to evaluate recomendations provided by the atlas and to participate in a dialogue to improve or alter these recomendations.
