Paper Abstract

In this paper, we provide a mathematical approach to reconstruct the Compton scatter and photo-electronic coefficients using the dual-energy CT system. The proposed imaging method is based on the mean value theorem to handle the non-linear integration coming from the polychromatic energy based CT scan system. We show a numerical simulation result for the validation of the proposed algorithm
