本文基于蒙特卡罗方法，模拟了不同源和探测器分离距离下光子在人脑组织和皮肤组织中的传播过程。我们实验中使用的人脑模型和皮肤模型分别有活层和七层。通过标记每个光子能到达的最深处，得到人体组织模型各层的后向散射强度。脑模型的仿真结果表明，在研究脑神经细胞的活动时，源-检测器的分离距离应选择在3厘米；为了对皮肤毛细血管的体积变化更敏感，源与检测器的分离距离应在8毫米左右。最后对今后的工作进行了展望。
In this paper, the photon propagation process in human brain tissue and skin tissue with various source and detector separation distances were simulated based on the Monte Carlo method. The human brain model and the skin model that were used in our experiments have live layers and seven layers, respectively. The backscattered intensity from every layer of the human tissue model was obtained by marking the deepest layer that every photon can reach. The simulation results of brain model indicated that the source-detector separation distance should be selected at three centimeters for studies on the actions of the brain nerve cells; in order to be more sensitive to the volumetric changes of capillaries in the skin, the separation distance of source and detector should be approximately eight millimeters. Future work was discussed at the end of the paper.
