Abstract
A method for reducing artifacts in computed tomographic (CT) images is provided that is particularly useful for CT applications requiring higher gantry rotation rates. The method includes selecting a set of thresholds for projection view data; utilizing a smoothing kernel in accordance with the selected set of thresholds to produce a set of smoothed projections from a set of original projections obtained from a scan of an object, wherein an amount of smoothing applied varies depending upon a relationship of the original projections to the thresholds; producing a set of final projections utilizing the set of original projections and the set of smoothed projections; and reconstructing images of the object utilizing the final projections.
