15CT 3343 METHOD FOR REDUCING PATIENT TRANSLATION ARTIFACTS IN TOMOGRAPHIC IMAGING Abstract of the Disclosure A method of reducing artifacts in images acquired with fan beam, helical scanning, tomographic imaging systems, applies a weighting function to the tomographic projection set. The weighting function reduces the contribution to the final image of projection data with large helical offset. Other redundant data within the projection set is increased in weight by the weighting function to prevent image artifacts from the weighting. In one embodiment, the projection set is centered on the slice plane to avoid discontinuities in the projection data caused by the weighting functions.
