SUVmean, SUVmax, SUVpeak, and MATV estimates computed for phantom spheres after automated segmentation for all experiments 1–3. Values are reported for estimates obtained with 3 different modalities (standard PET, PET reconstructed with a PSF model, and PET corrected with SFS-RR algorithm) alongside corresponding ground truth values.
