Comparisons of the artifact indexes (AIs) determined for in-focus plane images obtained using the cycle-GAN_pix2pix_MPN (CGpM-MAR) and other traditional reconstruction algorithms with and without metal artifact reduction (MAR) processing. Metal artifacts originating from the AIs of 6 (ROI_location_1) and 8 (ROI_location_2) selected metal artifact areas (features) and one background area are presented in the in-focus plane. Reference FBP, 0.69 mSv; (a) ROI_location_,1 0.43 mSv; (b) ROI_location_1, 0.31 mSv; (c) ROI_location_1, 0.20 mSv; (d) ROI_location_2, 0.43 mSv; (e) ROI_location_2, 0.31 mSv; and (f) ROI_location_2, 0.20 mSv.
