Abstract
A method of propagating a ray through an image includes providing a digitized volumetric image comprising a plurality of intensities corresponding to a domain of voxels in a 3-dimensional space, providing a reduced path octree structure of said volumetric image, said reduced path octree comprising a plurality of first level nodes, wherein each first level node contains a plurality of said voxels, initializing a ray inside said volumetric image, and visiting each first level node along said ray, wherein if said first level node is non-empty, visiting each voxel contained within each first level node.
