a Slice sensitivity profile at CFOV for DMI and DMI-DR. b Successive measurements of the count rate at CFOV and 10-cm radial offset using five aluminum sleeves and an extrapolation process to get the NEMA attenuation-free sensitivity in air. Comparison of the sensitivity results for the DMI and DMI-DR systems with results obtained in other centers [2,3,4,5] is presented in figures (c) and (d)
