Fig. 3From: SPECT image segmentation for estimation of tumour volume and activity concentration in 177Lu-DOTATATE radionuclide therapyRecovery coefficients for different reconstruction schemes. The reconstruction is with attenuation and scatter correction (AS) and with or without resolution compensation (R), and different numbers of iterations and subsets. a ASR-8-6, b ASR-16-15, c AS-8-6, and d AS-16-15Back to article page
