From: Phantom and clinical evaluation of bone SPECT/CT image reconstruction with xSPECT algorithm
Recovery coefficients of three reconstructions at various numbers of iterations. The numbers of iterations in a, b, c, d, e, and f are 12, 24, 36, 48, 60, and 96, respectively. In addition, the numbers of iterations in g and h show the different parameters of 36 and 48 in Flash 3D and 12 and 24 in xSPECT, respectively. Unfilled triangle indicates Flash 3D. Unfilled circle indicates xSPECT Quant. Unfilled square indicates xSPECT Bone
