Count-rates measured on the DSTE PET scanner: (a) Trues, (b) Randoms, (c) Scattered, (d) NEC. The measured rates followed the predictions by SimSET (Fig. 2) in relative distributions. SimSET overestimated NEC by 40%–50% for 2D, 2.7D, and 3D. Most importantly, the measured 2.7D NEC showed the advantage predicted by SimSET in the clinically relevant activity range of ~ 5 – 20 mCi.
