Fig. 4

Single-count rates versus signal-to-noise ratios (SNR) of the 10 to 37-mm diameter hot spheres of the IEC phantom for the noTOF (left panels) and TOF (median panels) images from the Vereos (upper panels) and Ingenuity (lower panels) cameras, together with the corresponding TOF-related gain, i.e., the ratio between the SNR of TOF and noTOF images (right panels). The dashed and solid vertical black lines correspond to respectively the lower and upper levels of single-count rates for the PET exams performed with the injections of 3 MBq.kg-1. The solid red vertical line corresponds to the estimated upper level of single-count rates for the PET exams performed with the injections of 5 MBq.kg-1
