Tumour volume and uptake accuracy using 40% fixed threshold and gradient segmentation. Difference between measured value and ground truth, plotted vs. ground truth, for metabolic tumour volume (MTV) and total tumour uptake (TTU) metrics. (Top to bottom) 40% FT and gradient segmentation. (Left to right) Reconstruction algorithms using OSEM + PSF (24 and 32 subsets respectively) and BSREM. Blue line indicates overall fit
