3D-Visualization of tomographic volume data using the generalized voxel-model

Abstract

Multi-slice images obtained from computer tomography and magnetic resonance imaging represent a three-dimensional image volume. For its visualization we use a ray-casting algorithm working on a gray scMe voxel data model. This model is extended by additional attributes such as membership to an organ or a second imaging modality ("generalized voxel model"). It is shown that the combination of different surface rendering algorithms together with cutting and transparent display allow a realistic visualization of human anatomy.
