Abstract

The Monte Carlo method with three input parameters, photon energy, scatter material, and material thickness, is used to calculate the scatter fraction and the point spread function of the scatter (PSF). Four scatter materials, C, Ca, H2O, and Al are tested using 50, 70, 90, and 110 keV monoenergetic sources. From this simulation, two conclusions can be made: (1) the PSF of scatter can be approximated as an exponential function, and (2) the scatter fraction shows energy dependence when expressed as a function of the product of linear attenuation coefficient and material thickness.
