Paper Abstract

A tomographical imaging system capable of reproducing electron density distributions of an irradiated object plane via measurement of the Compton scattered radiation is presented as a potential contender for portal imaging. The method which imposes minimal constraints on the measurement apparatus unlike most scanning methods is capable of density reconstruction with limited projections of scattered photon energy spectra acquired under conditions of wide angle source and detector collimation. As such, density reconstruction becomes a nonlinear inverse problem. This problem is presented along with a discussion on potential solution strategies to confine the impact of solution instability.
