Fig. 3From: Impact of a PMMA tube on performances of a Vereos PET/CT system adapted for BSL-3 environment according to the NEMA NU2-2012 standardCount rate performance, scatter fraction and count rate accuracy. A Scatter Count Rate, B Random Count Rate, C True Count Rate, D NEC rate, E Scatter fraction, F Relative Count Rate Error: Mean relative count rate errors for the different activity distributions. Mean values are shown as means (full lines) ± maximum/minimum values (dashed lines) with (red) and without (green) the PMMA tubeBack to article page
