Paper Abstract

The purpose of this paper is to present a new cone beam short scan reconstruction technique for circular and non-circular detector orbits. The reconstruction is performed by a filtered backprojection method. The short scan reconstruction technique is first investigated for fan beam circular orbits and is then extended to fan beam noncircular orbits. Finally a straightforward approach is applied to cone beam geometries and a modified Feldkamp algorithm is used. Since the projection data are incomplete cone beam reconstructions are only approximations. I.
