3D visualization of tomographic volume data using the generalized voxel model

Multi-slice images obtained from computer tomography and magnetic resonance imaging represent a 3D image volume. For its visualization we use a raycasting algorithm working on a gray-scale 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 the human anatomy.The investigations were supported in part by the Deutsche Forschungsgemeinschaft and the Werner Otto Foundation, Hamburg.
