Efficient CT Metal Artifact Reduction Based on Fractional-Order Curvature Diffusion

We propose a novel metal artifact reduction method based on a fractional-order curvature driven diffusion model for X-ray computed tomography. Our method treats projection data with metal regions as a damaged image and uses the fractional-order curvature-driven diffusion model to recover the lost in...
