Abstract

Radiation therapy is one of the most important procedures for treating cancer. When delivering the treatment, it is critically important that the position and orientation of the tumor volume and radiation sensitive structures that surround it are consistent with those assumed when designing the treatment plan. In this work, we investigate the potential of cone-beam local tomography for imaging tumor volumes using projection data that correspond to X-rays passing only through or near the tumor volume. The effect of projection truncation on the Feldkamp cone-beam reconstruction algorithm is also investigated.
