Equatorial slices of microspheres for NEMA-IQ and b-NEMA-IQ phantoms for intermediate (8.8) and high (21.2) TBR, two values of AC (1.3 and 2.2 kBq/ml) and two values of ESD (60 and 120 s). The impact of increasing ESD or AC is evident in the greater visibility of the 8.1-mm microsphere. The increase of TBR allows visibility of the 6.5-mm microsphere. At intermediate TBR (8.8) and low AC (1.3 kBq/ml), no microsphere is detectable
