The upper and lower rows are the images of the dental phantoms shown in Fig. 6a, b, respectively. a, e The images reconstructed without metal artifact correction. b, f The images reconstructed by the FP-MAR method with a global threshold of 0.07 (partial segmentation of the metallic objects). c, g The images reconstructed by the FP-MAR method with a global threshold of 0.1 (full segmentation of the metallic objects). d, h The images reconstructed by the proposed method with a global threshold of 0.07 (p = 10, c = 0.1)
