Abstract :
Reconstruction for an incomplete circular scan typically results in artifacts due not only to data incompleteness, but also to non-optimal handling of data redundancy. We present a novel reconstruction approach aimed at improving the handling of redundant data after first analyzing how such redundancy is handled in a more traditional approach.
