title: Comparison of the St. Petersburg phantom with a BOMAB phantom in the ORTEC StandFast whole body counter: a Monte Carlo simulation.
abstract: Three sizes of the St. Petersburg phantom have been compared to six sizes of BOMAB phantoms measured by a virtual StandFast whole body counter using Monte Carlo simulations to investigate if the counting efficiencies are equivalent. This work shows that previously published data comparing the Reference Man sized phantom at 662 keV is supported; however, the simulations also show that the smaller sized St. Petersburg phantoms do not agree well with BOMAB phantoms. It is concluded that, compared with BOMAB phantoms, the St. Petersburg phantoms are system dependent and that they should be validated over a wide photon energy range against corresponding BOMAB phantoms prior to their use for calibrating whole body counters.
