Bone-induced streak artifact suppression in sparse-view CT image reconstruction

Table 1 Means and standard deviations, RRMEs and SIs in the contrast phantom images

	Contrast Phantom Case
Reconstruction Methods	Mean values ± standard deviations	RRME	SI
ART	0.1787 ± 0.0172	0.0095	0.4471
CS	0.1784 ± 0.0033	0.0032	0.3014
SAS-CS	0.1783 ± 0.0022	0.0027	0.2966

Three iterative reconstruction methods, ART, CS, and SAS-CS, are compared for the 60-view imaging. Mean values and standard deviations have been calculated from the pixel-intensity profiles in Figure 5a.
