From: Fully digital PET is unaffected by any deterioration in TOF resolution and TOF image quality in the wide range of routine PET count rates

Fig. 5

Representative examples of PET slices of the IEC phantom recorded with the TOF information with the Vereos (upper panels) and the Ingenuity (lower panels) at count rates corresponding to the same levels of activity concentrations for both cameras (i.e., at background concentrations of the IEC phantom of 2, 5, 10, 20, and 40 kBq.mL-1). The values of signal-to-noise ratio (SNR) and contrast recovery coefficients (CRC) for the 10 to 37-mm diameter hot spheres are inserted in each image, together with the background relative noise (RN)
