FIG. 9. — Demonstration of the effect of different D_eff and L_eff values on the performance of the library-based scatter correction. (A) The scatter correction results using different values. The first column shows the uncorrected image (upper) and the corrected image (bottom) using an estimated D_eff of 14 cm. The rest of the upper row: image corrected using different D_eff values. Display window: [0.2 0.3] cm⁻¹. The rest of the bottom row: difference images compared with the result using a D_eff value of 14 cm. Display window: [−0.03 0.04] cm⁻¹. (B) The scatter correction results using different L_eff value. The first column shows the uncorrected image (upper) and the corrected image (bottom) using an estimated L_eff of 0.75D_eff. The rest of the upper row: images corrected with 0.5D_eff and 1D_eff. The bottom row: the corresponding difference images compared with the result using a L_eff of 0.75D_eff. The display windows for uncorrected/corrected images and difference images are the same as those in (A).
