From: Image quality and metal artifact reduction in total hip arthroplasty CT: deep learning-based algorithm versus virtual monoenergetic imaging and orthopedic metal artifact reduction

Fig. 4

Conventional (a), 130-keV monoE (b), conventional with O-MAR (c), 130-keV monoE with O-MAR (d), and DL-MAR (e) images of a patient with unilateral total hip arthroplasty at height of the acetabulum. Severe metal artifacts on the conventional CT image and 130-keV monoE that are strongly reduced by O-MAR. Even stronger reduction can be observed on the DL-MAR images. Window: width 400, level 40 HU.
