%X In Computed Tomography (CT), the beam hardening artifacts are caused by polychromatic X-ray beams applied in real medical imaging. In this article, we applied the recently proposed box-constrained nonlinear weighted anisotropic total variation regularization (box-constrained NWATV) method in the process of the reconstruction. We do numerical experiments to validate the advantages of the proposed method in reducing the beam hardening artifacts compared with the existing ways.
