Abstract: In this paper, we propose a new metal artifacts reduction algorithm
based on fractional-order total-variation sinogram inpainting model for X-ray
computed tomography (CT). The numerical algorithm for our fractional-order
framework is also analyzed. Simulations show that, both quantitatively and
qualitatively, our method is superior to conditional interpolation methods and
the classic integral-order total variation model.
