    Three-dimensional medical imaging methodologies are surveyed with respect to hardware versus software, stand-alone versus on-the-scanner, speed, interaction, rendering methodology, fidelity, ease of use, cost, and quantitative capability. The question of volume versus surface rendering is considered in more detail. Research results are cited to illustrate the capabilities discussed.<> View full abstract»

    Five hardware architectures for volume rendering, which requires efficiently handling a huge amount of volumetric data, are surveyed, categorized, and compared. They are Cube, Insight, PARCUM, Voxel Processor, and 3DP. General-purpose graphics systems that exploit their surface-based geometry engine to reduce the computational burden of the rendering process are briefly reviewed.<> View full abstract»

    The role of 3-D imaging in medicine and the questions it raises regarding what should be automated and how the information is to be used are addressed. The discussion then turns to imagery generated by equipment using computed tomography (CT), magnetic resonance (MR) images, or positron/single-photon emission tomograms (PET/SPECT). Such image data are considered as spatial image sequences. Low-lev... View full abstract»

    A practical simulation system based on analysis of clinical surgical procedures is described. The system provides fundamental manipulation operations to simulate actual surgical activities. There is a simulated cutting operation for sectioning a bone into various arbitrary shapes, a movement operation to transport a bone block to a desired position, and a restricted-movement operation to move a bo...

    Areas where significant progress is needed are outlined. A unified conceptual framework based on generic tasks, showing the intricacies and the dependences that exist among completely distinct and intensive research lines, is defined. True 3-D volume imaging devices are then discussed, with the main emphasis on vascular network reconstruction. Segmentation issues are briefly reviewed. The fusion o... View full abstract»
