title = "Impact of fano factor on position and energy estimation in scintillation detectors",

abstract = "The Fano factor for an integer-valued random variable is defined as the ratio of its variance to its mean. Light from various scintillation crystals has been reported to have Fano factors from sub-Poisson (Fano factor < 1), Poisson (Fano factor = 1) to super-Poisson (Fano factor > 1). For a given mean, a smaller Fano factor implies a smaller variance and thus less noise. We investigate if lower noise in the scintillation light results in better spatial and energy resolution in a scintillation imaging detector. The impact of Fano factor on estimation of position of interaction and energy deposited in simple gamma-camera geometries is estimated by calculating the Cram{\'e}r-Rao bound. The calculated Cram{\'e}r-Rao bound is quantitatively validated by estimating the variance of the maximum likelihood estimator.",
