Abstract

Monte Carlo Simulation for light propagation in different types of human and animal tissues has been performed using programming methods. During the simulation we have recorded the photon reflectance, transmittance and absorption in lung and dermis tissues of human, pig and rabbit and compared. Average values of total diffuse reflectance, transmittance and absorption have been calculated by the 10 simulations of 100,000 photons for these tissues at 633 nm. We have found that transmittance, reflectance and absorption are strongly dependent on tissue type and diffuse reflectance increases as the scattering coefficient (μ s ), increases or anisotropy (g), decreases, while diffuse transmittance increases as absorption coefficient (μ a ) or (μ s ) decreases, or as (g) increases.
