This work presents a novel computed tomography reconstruction method for few‐view problem based on a compound method. To overcome the disadvantages of total variation (TV) minimization method, we use a high‐order norm coupled within TV and the numerical scheme for our method is given. We use the root mean square error as a referee. The numerical experiments demonstrate that our method achieves better...
Metal artifact reduction (MAR) is still a challenging problem in current computed tomography reconstruction. Traditional methods usually use the unaffected projection data in the same degree to interpolate contaminated positions in the bins. The continuality and smoothness features become hard to fulfill. In this article, we propose a novel noniterative MAR method that uses coherence transport with...
