摘要
采用杂合算法,讨论了折射率对不同吸收系数的生物组织漫反射光分布的影响。计算结果表明,在近源处生物组织的折射率越小,漫反射光模拟计算的相对误差越小;而在远离源处,其相对误差随折射率的增大而减小。同时也说明杂合模型不太适合模拟强吸收生物组织的漫反射光分布。
In this paper,the effect of refractive index on distribution of the diffuse reflectance in biological tissue was investigated.The results indicate that the relative error decreases with the refractive index decreasing near the point source,whereas it decreases with the refractive index increasing far from the point source.At the same time,the results also demonstrate that the hybrid model is not suitable for simulating diffuse reflectance in biological tissue with strong absorption.
