Suppression of Computed Tomography Metal Artifacts Using Curvature Driven Diffusions Based Sinogram Inpainting

摘要

In this paper, we propose an efficient metal artifacts suppression algorithm based on curvature driven diffusions (CDD) sinogram inpainting model for computed tomography (CT) and the numerical scheme of our method is also given. The experiments show that on both quantitative and qualitative sides, the model we proposed is superior to conditional interpolation methods and classic total variation model.
