Effect of Hybrid Iterative Reconstruction on CT Image Quality Using Metal Artifact Reduction

Abstract

Both Artifact and Artifact increased according to the strength of AIDR 3D. The variations of Artifact and Artifact, due to the AIDR 3D strength, were small and large, respectively. Further, in comparison with a high dose, the effect of artifact emphasis increased at low dose. Therefore, it should be noted that stronger AIDR 3D can emphasize the residual metal artifact.
