"WebRather than individual voxels, a new exact algorithm is presented that considers the CT data as consisting of the intersection volumes of three orthogonal sets of equally spaced, parallel planes. For a three-dimensional CT array of N 3 voxels, the new exact algorithm scales with 3N, the number of planes, rather than N 3, the number of voxels. " - Siddon's ray-voxel intersection
