Monte Carlo simulation of laser light scattering in mammalian organs

On the basis of experimentally measured backscattering surface profiles of heart, lungs, liver, kidney and spleen, the absorption and isotropic scattering coefficients, by Monte Carlo simulation, are determined and are used for optical characterization of these organs. The photon backscattering and the distribution within the organ vary depending on these coefficients. There is a significant organ to organ variation of reflectance, transmittance and absorbance with the increase of organ thickness. The pattern of variation of these parameters for spleen is significantly different from that of other organs.
