摘要
Methods for three-dimensional projecting and backprojecting rays with respect to voxels/detector bins to attenuate/eliminate high-frequency artifacts, are disclosed. A distance-driven technique wherein the transitions of the voxels and the detector bins are respectively projected onto a predetermined plane. This projection allows a determination of the contribution of each of the voxels/bins for each of the bins/voxels with lower computation time and improved artifact free images.
