Foil 20 A4 - Medical Collaboration and Visualization System

From Collaborative and Interactive Visualization Project Second Quaterly Review Review Meeting at NPAC -- 18 March 1996. by Geoffrey C. Fox * See also color IMAGE

Focus: 3D interactive visualization of human internal organs in their true form and shape; supported by Web-based (video) conferencing
3D imaging - visualization, manipulation, extraction and analysis of multidimensional medical structures
  • Slice imaging (extract 2D images)
  • Projective imaging (allows 2.5D mode)
    • Surface rendering - visualization based on object boundaries
    • Volume rendering - direct visualization of voxel data
  • Volume imaging (holography) - true 3D mode
Traditionally, volume renderers produce their images by one of three methods: ray casting, splatting and forward projection
The result is displayed on the 2D screen - illusion of depth is created via shading, showing only visible parts, transparency, stereo display, and animation
