【摘要】 利用蒙特卡罗方法对同一组光学参数分别模拟了半无限大平面、单层柱状和双层柱状生物组织中的吸收光子数密度,结果显示不同边界情况下光在生物组织中的传输有明显的差别。讨论了边界对生物组织中光传播的影响,模拟了柱状生物组织中的能流率随空间坐标的变化,并与实验结果进行了比较,验证了模拟计算的正确性。更多还原

【Abstract】 The number density of photons absorbed in semi-infinite plane,simple columnar and double columnar biological tissues is numerically studied with Monte-Carlo method,respectively.The same optical parameters are used in the simulation for the three situations.The results show that the boundary employed in the simulation has important effect on the light propagation in tissue.The effect of boundary on light propagation in tissue is investigated.Energy flow rate in biological tissue as a function of radial distance is simulated and the results agree well with experimental results.更多还原
