Artifact Suppressed Nonlinear Diffusion Filtering for Low-Dose CT Image Processing

Artifact Suppressed Nonlinear Diffusion Filtering for Low-Dose CT Image Processing

Computed tomography (CT) images with a low-dose protocol generally have severe mottle noise and streak artifacts. In this paper, we propose a novel diffusion method named “artifact suppressed nonlinear diffusion filtering (ASNDF),” to process low-dose CT (LDCT) images. Differen...
