Surgical training systems based on virtual reality (VR) and simulation techniques for tissue deformation may represent a more cost-e!ective and e$cient alternative to traditional training methods. Additionally, VR is a technology that can teach surgeons new procedures and can determine their level of competence before they operate on patients. At(More)
We present a full featured surgery simulator for endoscopic third ventriculostomy (ETV) in an interactive grid environment. The basic ventriculostomy simulator introduced previously has been extended with new 3D models and animation methods for raising the simulation realism. It enables full haptic interaction with textured deformable models of a(More)
—In order to understand the dependencies in the power system we try to derive state information by combining high-rate voltage time series captures at different locations together with data analysis at different scales. This may enable large-scale simulation and modeling of the grid. Data captured by our recently introduced Electrical Data Recorders (EDR)(More)

The introduction of computer-based training systems for laparoscopic surgery has increased the training quality and made the learning effect measurable with objective criteria. This paper introduces VSOne as a fully-featured virtual reality training system for laparoscopic surgery. VSOne utilizes the state-of-the-art in virtual reality techniques, soft(More)
The increasing computing power of graphics workstations in the last years enabled the arise of virtual reality based surgery training systems, which have many advantages over traditional training methods. Especially in the field of minimally invasive surgery, the " Karlsruhe Endoscopic Surgery Trainer " , which is based on the simulation software KISMET,(More)
— This paper introduces a virtual arthroscopy training simulator as a beneficial tool for partial meniscectomy procedure. The modeling methods of virtual environment, haptic interface establishment, and the system integration are described in detail. With the combination of interactive visual and haptic feedback, the simulator is designed to aid surgeons in(More)
