Noise effective count-rate (NECR) analysis has been used to compare brain scanners of 53, 60, and 66 cm diameter with the GE ADVANCE whole body scanner (93 cm diametr). Monte Carlo simulations of a brain-sized phantom (16 cm diameter, 13 cm length) in the ADVANCE geometry are used to develop a model for NECR performance, which is reconciled to results from a decay series measurement. The model is then used to predict the performance of brain scanner designs.
