Feature-based interactive visualization of volumetric medical data

To provide fast display and manipulation of the 3D reconstruction of volumetric data, our system uses surface rendering which reduces 3D data sets to geometric primitives that have been implemented in the SGIs hardware, so a better performance of rendering speed is obtained. Our system supports both basic and advanced navigation features of medical data sets, including translating, rotating, zooming in/out, advanced cutting functions (transparent alignment, multi-plane cut, cut in any orientation and depth), classification of tissues, and centralization function. The 3D interface of our system provides users realistic view and feature-based manipulation of the medical data sets to extract useful information for medical training and education
