Summary: The present work describes the development of a neurosurgical training simulator for intracranial procedures that is based on virtual reality. In order to construct the interface between user and simulator as native as possible, a real surgical microscope is used. The microscope can be positioned freely above a phantom of a head. As to adapt the virtual reality, position and pose of the microscope are determined by an optical tracking system. The values of zoom and focus are read out via a CAN bus. The oculars of the optical system were replaced by a stereo display that shows the computer generated scenario in 3D. By using different instruments the user can interact with the virtual world. Position and pose of the instruments that are inserted in the patient phantom are determined by a combination of optical and inertial tracking procedures. Abstract training modules for the training of basic skills were implemented as well as a real medical procedure that consists of the clipping of an aneurysm. The simulator is based on a modular software design. It is extendable by plugins. The tra
