The purpose of this paper is to present a fan beam short scan reconstruction technique for non- circular detector orbits. It applies a smoothing window to the projection data, and then a modified filtered backprojection method is performed. This technique is exact and the smoothing window is orbit independent; yet it requires more data than current circular-orbit short scan algorithms.
