Fig. 7From: Evaluation of Iodine-123 and Iodine-131 SPECT activity quantification: a Monte Carlo studyUncorrected projection images (a, c, e), and reconstructed corrected transaxial slices (b, d, f) through the voxel-based digital patient phantom for a, b 123I LEHR, c, d 123I ME and e, f 131I HE. Profiles through the largest sphere are displayed alongside their respective images. Arrows indicate septal scatter and penetration at peak and trough and at tail regionBack to article page
