用Monte Carlo方法模拟激光在肿瘤组织内的传播

Monte Carlo Simulation of the Transportation of Lasers in Tumor

本文建立了肺部肿瘤组织的模型，采用蒙特卡络方法来模拟激光在其中的传播，得到了激光在模型中的能量分布，分析了影响激光能量分布和治疗效率的因素，并比较了会聚光束和平行光束在治疗效率上的差异。

We established a layered model of carcinomatous bronchial tissue,and with Monte Carlo method,we simulated the transportation of lasers in it.We obtain the distribution of energy in the model,discussed the factors that may have influence on it,and simulated parallel and converged light to compare their effectiveness in curing tumor.
