Results from the IEC phantom and lung insert with the comparisons between digital PET (blue lines) and analog PET (red lines) and for images reconstructed with the TOF information (TOF, solid lines) and without the latter (noTOF, dashed lines) of (1) the relationships between signal-to-noise-ratio (SNR) and contrast recovery coefficients (CRC) for the 37-mm cold sphere (a), and (2) the % error correction as a function of the number of OSEM iterations (b). Crosses and triangles are defined in the legend of Fig. 1
