Scattering Specific Characteristics of Continuous Medium for Monte Carlo Simulations of Light Transport in Turbid Biological Tissues

摘要

Using examples of 1D and 2D pure scattering problems and a single-scattering approximation, the paper considers the derivation of expressions for the scattering coefficient and the phase scattering function for a continuous medium as the limiting case of scattering on a group of discrete scatterers. It is shown that the use of this approach to construct the cumulative distribution function (CDF), which serves to simulate the scattering angle at numerical Monte Carlo simulations, leads to the dependence of CDF only on the normalized scattering phase function of a single scatterer.
