A new algorithm will be presented for tomographic reconstruction from
fan beam data acquired with a quarter detector shift. This algorithm
exploits the reflection property of the divergent beam transform by
representing the sample and reflected points as a discrete,
multichannel sample set. The algorithm can be used to reconstruct
images from a third generation CT scanner at the maximum resolution
consistent with the frequency characteristics of the detector.
