COMPENSATION FOR VIEW ALIASING ARTIFACTS IN RADIATION IMAGING, IN PARTICULAR IN COMPUTER TOMOGRAPHY

摘要

Methods and apparatus to reduce and eliminate aliasing artifacts (64) generated as a result of performing high speed scans (52) are described. In one embodiment, the method includes the steps of applying a weighting function (56) to the projection data (54), and determining an aliasing index (58) from the weighted data. The aliasing index per view is utilized to determine the region and the amount of synthesized views required to reduce the aliasing artifact.
