Présentation Matthias Harders
Developments in Virtual and Augmented Reality Surgical Training
Computer-based surgical simulation is an appealing option to supplement traditional clinical education. Several training systems have been developed in the past; however, the majority of these focus on minimally-invasive procedures, while the simulation of open surgery is still in its infancy.
In this presentation, I will provide an overview of our current activities in surgical simulation. First I will provide a general motivation of the field. This will be followed by an example of aVirtual Reality-based training system for arthroscopic interventions. I will specifically address the soft tissue deformation model and a special approach of adding details to low-resolution simulations. Thereafter, I will briefly outline an alternative strategy to realize open surgery simulation, using Augmented Reality technology. The underlying idea of this approach is to overlay a virtual representation of the operation site onto a real patient dummy. In this context, I will address some of the differing technological requirements, such as the handling of occlusions.
Matthias Harders is lecturer and senior researcher at the Computer Vision Lab of ETH Zurich, and leader of the Virtual Reality in Medicine Group. Current research focuses virtual and augmented reality, haptic interaction, and biomedical simulation. He studied Computer Science with focus Medical Informatics at the University of Hildesheim, Technical University of Braunschweig, and University of Houston. He finished his doctoral thesis on visual-haptic medical segmentation at ETH Zurich in 2002. He completed the habilitation at ETH Zurich in 2007. He is co-founder of the EuroHaptics conference, the EuroHaptics Society, and the IEEE RAS/CS Haptics Technical Committee. He is also a co-founder of the ETH spin-off company VirtaMed which focuses on commercializing surgical training systems.
