Images reconstructed with different image correction combinations. Rows were the images of different T/B ratios (32:1, 16:1, 8:1, and 4:1, respectively, from the top to the bottom; a 32:1; b 16:1; c 8:1; d 4:1); Columns are the images reconstructed with different correction combinations (1, AC + SC + RR; 2, AC + RR; 3, AC + SC). Fixed reconstruction parameters: 35 iterations, 20 subsets, no filter; Fixed acquisition parameters: 120 s/frame of acquisition time, 15% energy window
