Surgical scene generation for virtual reality-based training in medicine

Recent years have brought about a drastic change in patient awareness and acceptance of adverse effects in medical care. The combination of this process with an increasing focus on patient safety has put traditional educational paradigms in the medical area to the test. The potential of training approaches using virtual reality techniques has been recognized for sometime and a key element of VR-based training is the ability to generate various scenarios. Therefore, the book examines in detail the main components required to define a scenario, in the context of surgical scene generation: Generation of the scene geometry - Modelling of organ appearance - Definition of biomechanical parameters. The book is the ideal reference for any reader involved in generating trainingscenarios, as well as in VR-based training in general. Provides an extensive overview of related work in the three different directions of scene generationand introduces specific solutions in detail INDICE: Introduction. Surgical Education. Geometry.
