Title

On Two Versions Of A 3Π Algorithm For Spiral Ct

Abstract

A 3π algorithm is obtained in which all the derivatives are confined to a detector array. Distance weighting of backprojection coefficients of the algorithm is studied. A numerical experiment indicates that avoiding differentiation along the source trajectory improves spatial resolution. Another numerical experiment shows that the terms depending on the non-standard distance weighting 1/ x - y(s) can no longer be ignored. © 2004 IOP Publishing Ltd.
