1. A method for viewing a 3-D voxel-based image represented in discrete 3-D voxel space, said method comprising the steps of:

  • (a) retrieving the voxels of said 3-D voxel-based image along at least one retrievel direction using retrieval parameters; and

    (b) along any arbitrary viewing direction specificable by viewing parameters, viewing said 3D voxel-based image in said discrete 3-D voxel space, independent of said retrieval parameters; and

    (c) storing said 3-D voxel image is said discrete 3-D voxel space according to a first skewed memory storage scheme which provides for said simultaneous accessing of said plurality of voxels along at least one said retrieval direction so as to form a plurality of voxel based retrieval rays, said first skewed memory storage scheme involving mapping the voxels of said 3-D voxel-based image in said discrete 3-D voxel space into a first skewed memory storage space.
