CT Metal Artifact Reduction Method Based on Improved Image Segmentation and Sinogram In-Painting

Table 2

MSE and STD on the original corrupted and corrected phantom images. We can see the calculated MSE and STD are lower for the images corrected with our method.

		Original uncorrected image (Figure 4(a))	Image corrected by the Bal algorithm; (Figure 8(a))	Image corrected by the proposed method; (Figure 8(a))
MSE of the whole images		1.37	1.31	1.26
STD	Region1	302.98	64.21	42.20
	Region2	293.52	99.04	56.81
MSE	Region1	15.15	3.27	2.16
	Region2	6.22	2.66	1.13
