Study of light propagation in human, rabbit and rat liver tissue by Monte Carlo simulation

Monte Carlo Simulation for light propagation in liver tissues of human and animal was done using Monte Carlo simulation. During the simulation we recorded the photon reflectance, transmittance and absorption of human, rabbit and rat liver tissues. Then their comparative studies were done. Average values of total diffuse reflectance, transmittance and absorption were calculated by the 10 simulations of 100,000 photons for these tissues at 633 nm. We found that diffuse reflectance increases as μ_s increases or g decreases and diffuse transmittance increases as μ_a or μ_s decreases, or as g increases. It is also concluded that the radially resolved diffuse reflectance of the tissues decays exponentially of second order.
