“…First proposed virtual endoscopy systems for visualization of paranasal sinuses based on patient image data used specialized hardware [19] or generated off-line fly-throughs along a pre-defined path [14] due to the limited computational power. The visualization of more recent systems is based on highly optimized software [11] or GPU based [7] raycasting algorithms that allow to add more realism, like realistic lightening or wetness, without loosing interactivity.…”

“…This involved two parallel developments, one focusing on surface-based representations 19,20 , the second focusing on volumetric representations. [21][22][23][24][25][26] These studies showed that although surface-based representations were expedient and could provide interactive rates, they lacked the complexity and realism found in volumetric displays. 27 The ENT Surgical Trainer, as it has come to be known, has been identified as the first true procedural surgical simulation environment to undergo vigorous validation.…”

Background-Through previous and concurrent efforts, we have developed a fully virtual environment to provide procedural training of otologic surgical technique. The virtual environment is based on high-resolution volumetric data of the regional anatomy. This volumetric data helps drive an interactive multi-sensory, i.e., visual (stereo), aural (stereo), and tactile simulation environment. Subsequently, we have extended our efforts to support the training of neurosurgical procedural technique as part of the CNS simulation initiative.

With the recent development of endoscopic instruments, laparoscopic surgery has come into widespread use. Compared to traditional open abdominal surgery, the method offers a reduction of the physical burden on the patient, the in‐hospital period, and the recovery period. On the other hand, more technical training is required compared to open surgery, since the surgery is conducted by observing a two‐dimensional image obtained by lapar‐oscopy. Many simulators for training have been developed in various research institutions. Most of these, however, require expensive high‐performance hardware, and there is a need for a low‐cost PC‐based virtual laparoscopic surgery simulator. The important issues in constructing such a simulator are a forceps input device and an organ model representation which can be deformed or cut. This paper reports both a forceps input device and an organ model which can be deformed and cut. The organ model consists of a mass‐spring model. In the deformation algorithm, an equation for force‐displacement balance is used. When the forceps contacts an object, mismatching of the model deformation is eliminated by fine segmentation of the area surrounding the point of contact. When an object is to be cut, the fine segmentation area surrounding the area of contact with the forceps is enlarged with the progress of the incision area, maintaining the continuity of the process. © 2002 Wiley Periodicals, Inc.
