| Abstract(in English) | Photon-counting CT is an emergence technology which has many advantages compared with conventional CT. However, ring-artefacts are often appeared in reconstruction images due to non-uniformity of energy-threshold and sensitivity. Many methods have been proposed to remove the ring-artefacts, which lead other problems such as blurring. In this study, we propose a new method with compressed sensing, which can remove the ring-artefacts without blurring. |
