Abstract

Because of the importance of the so-called long object problem, spiral cone-beam computed tomography (CT) has become a hot area in the CT field since it was first proposed in 1991. As a main stream in the development of the next generation medical CT, spiral cone-beam CT has been greatly improved, especially in the aspect of image reconstruction methods. Now, the state-of-the-art cone-beam algorithms can reconstruct images exactly from longitudinally truncated data collected along a rather general scanning trajectory. Here we present a brief overview of this area with an emphasis on the results achieved by our team.
