| 摘 要： | 应用一种新的随动坐标系转换方法,给出用于转换生物组织中光子空间传输坐标的矩阵方程。该方程具有递推的形式且只涉及乘法运算,避免了传统算法中的计算溢出。将其用于光在生物组织中传播的蒙特卡罗模拟,表明可以有效节约机时,提高模拟效率,得到与传统坐标系相一致的结果。

| Abstract: | A new transformation method for follow-up coordinate system is used and a matrix equation for transforming spatial transporting coordinate of scattering photons is given. The equation has recursion form and only relates to multiplication and will not lead to overflow in calculation. The equation is applied to Monte Carlo simulation in the light propagation in bio-tissues. The results show it can effectively save CPU time and improve simulation efficiency. The results are also in good agreement with the results from the traditional method. |
