Abstract :
In this paper, we propose a new class of super-short-scan algorithms for image reconstruction from fan-beam projections. Furthermore, we extend the resulting algorithms to image reconstruction from truncated fan-beam projections. By simulation studies, we demonstrate that the new algorithms are comparable to the existing ones.
