Abstract
A method for improving the quality of a projection image. The method includes setting a plurality of rays that pass through voxels. Each ray corresponds to a pixel. The method further includes storing a plurality of pixel values, each associated with one of the voxels existing on each of the rays. The method also stores a plurality of coordinates, each corresponding to one of the pixel values, and determines a noise position in the voxels pixels based on the coordinates.
