Correction of severe beam‐hardening artifacts via a high‐order linearization function using a prior‐image‐based parameter selection method

Purpose Polychromatic x‐rays are used in most computed tomography scanners. In this case, a beam‐hardening effect occurs, which degrades the image quality and distorts the shapes of objects in the reconstructed images. When the beam‐hardening artifact is not severe, conventional correction methods c...
