Abstract In this paper, we present a system for performing a complex surgical intervention using virtual reality (VR) technology. With the aid of the system, the intervention can be planned and simulated exactly before performing it in reality and important additional information can be achieved during the simulation. Before working in VR, finite element models of the patient's head are generated form CT-images. Based on these models, additional work is done in VR, where the patient's skull is cut into several pieces, which are then re-positioned. Based on moving and shifting the obtained pieces, the goal is to increase the volume inside the skull, which is called intracranial volume. Until now, it was not possible to measure the achieved increase of the intracranial volume. However, by using our system is it now possible to calculate this volume online during each step of our virtual intervention. The obtained results are used for the surgical intervention in reality.
