利用蒙特卡罗方法对光在人和动物肝组织中的传播进行了蒙特卡罗模拟。在模拟过程中，我们记录了人、兔和大鼠肝组织的光子反射率、透射率和吸收率。然后对他们进行了比较研究。通过对这些组织在633 nm处100,000个光子的10次模拟，计算出总漫反射比、透射率和吸收率的平均值。我们发现，漫反射系数随Mu(S)增大或g减小而增大，漫反射系数随Mu(A)或Mu(S)减小而增大，或随g增大而增大。研究还得出结论：组织的径向分辨漫反射系数呈二阶指数衰减。(C)2010年爱思唯尔股份有限公司。版权所有。
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 mu(s) increases or g decreases and diffuse transmittance increases as mu(a) or mu(s) decreases, or as g increases. It is also concluded that the radially resolved diffuse reflectance of the tissues decays exponentially of second order. (C) 2010 Elsevier GmbH. All rights reserved.
