TV-regularized CT Reconstruction and Metal Artifact Reduction Using Inequality Constraints with Preconditioning
Clemens Schiffer
Total variation(TV) regularization is applied to X-Ray computed tomography(CT) in an effort to reduce metal artifacts. Tikhonov regularization with data fidelity term and tot…

Sinogram constrained TV-minimization for metal artifact reduction in CT
Clemens Schiffer, Kristian Bredies
A new method for reducing metal artifacts in X-ray computed tomography (CT) images is presented. It bases on the solution of a convex optimization problem with inequality constrain…
