Paper Abstract

In our previous studies,"2 we had shown the utility of multivariate momentgenerating functions (MMGF) for analyzing the influence of stochastic amplifying and scattering mechanisms on the transfer of signal and noise through multistage imaging systems. Recently, we extended these studies to include cases in which the amplification or scattering parameters are themselves stochastic variables.3 In this paper we consider a special case in which amplification is followed by scattering such that the same random variable which characterizes the parameters of each amplification process also characterizes the parameters of the subsequent scattering of the amplified output events. In radiographic imaging, this can be used to describe the physics of the depth dependence of emission efficiency and light scatter in x-ray intensifying screens which was originally treated by Lubberts.4 In this work Lubberts' original results are rederived in a more general form.
