摘　　要：基于腕部手厥阴心包经循行区域的解剖结构,建立了腕部手厥阴心包经和旁开非经络线区域组织光传输结构的简化模型,并利用蒙特卡罗模拟的方法分别模拟了光在腕部手厥阴心包经、相邻肌腱以及旁开非经络线上的光传输特性。模拟结果表明,光沿腕部手厥阴心包经呈优势传输,与本实验室之前实验所得的结果相一致。分别计算了三个模型中各层的光通量情况,计算结果表明,腕部心包经循行区域的光传输特性主要受该区域的底层结构和底层组织成分影响,光在底层结构中也是沿腕部心包经呈优势传输的,并且该优势传输的现象与腕部心包经底层的筋膜间隙结构有关。The characteristic of light transportation along the pericardium meridian line and its surrounding areas at the wrist is studied by using Monte Carlo method. Three simplified models for Monte Carlo simulation are built based on the anatomical structure. The light propagation along the pericardium meridian line, the tendon and the non- meridian line nearby are simulated separately. The simulation results show strong accordance with the previous experimental results that the light propagation along the pericardium meridian has an advantage over its surrounding areas at the wrist. Luminous flux in different layers on the three paths are calculated, and the results show that the optical transmission characteristics in this region is mainly affected by its underlying structure and its underlying tissue composition. Besides, light transportation in the underlying tissue of the pericardium meridian line also has an advantage and the advantage transmission significantly correlates with the closed anatomical structure of the underlying tissue.
