Paper Abstract

Metal artifacts are increasingly prevalent in CT reconstructed volumes due to the presence of implants in the aging population. High degree of beam hardening in severely attenuating objects is one of the main contributors of strong metal artifacts. In this paper, we propose a method to reduce metal artifacts due to beam hardening by enforcing consistency conditions on the uncorrected polychromatic projections. Our results from clinical datasets show the reduction of artifacts after the proposed correction.
