Abstract

The directional total variation algorithm (DTV) reported in the literature achieves promising results for limited angle reconstructions, especially when the scanning angular range is very small. However, the visible edge prior for limited-angle CT is not explicitly considered by DTV. In this paper, a variant of the DTV model is proposed which explicitly builds into the visible edge prior developed by Quinto et al. Numerical experiments show that the proposed model and algorithm produce very competitive results compared to DTV.
