Summary:PROBLEM TO BE SOLVED: To reduce noise or artifacts due to scatter in a wide-cone X-ray computed tomography (CT) system or the like.SOLUTION: Approaches for deriving scatter information using inverse tracking of scattered X-rays is disclosed. In certain embodiments, scattered rays are tracked from respective locations on a detector to a source of the X-ray radiation, as opposed to tracking schemes that proceed from the source to the detector. In one such approach, the inverse tracking is implemented using a density integrated volume that reduces the integration steps performed.
