A Direct Sinogram Correction Method to Reduce Metal-Related Beam-Hardening in Computed Tomography
This paper proposes a direct sinogram correction method that does not require metal segmentation and prior knowledge to reduce metal-related artifacts in polychromatic computerized tomography (CT). The metal-related artifacts, being common in dental conebeam CT images, are caused by beam hardening-i...
