| 目的 验证3个蒙特卡罗程序MCNP、EGSnrc、DPM计算结果的一致性问题。 方法 基于简单均匀及非均匀模型和复杂临床头部实例模型,对3个蒙特卡罗程序MCNP、EGSnrc、DPM的模型建模、计算结果、计算时间进行了比较研究。结果 尽管3个程序在粒子输运原理、模拟参数设置、几何描述模型以及材料截面数据等方面存在不同,但是计算结果仍符合很好。结论 3个蒙特卡罗程序计算复杂模型具有相当的可靠性;简单快速蒙特卡罗程序DPM具有明显的优势。 |

| Objective To validate the calculated result consistency of three Monte Carlo codes MCNP,EGSnrc and DPM. Methods A homogeneous model, an inhomogeneous model and a clinic head case were simulated using Monte Carlo codes MCNP,EGSnrc,DPM to study and compare their model modeling, calculation result and calculation time. Results It is shown that, despite there are differences in particle transport principle, modeling parameter setting, geometry description and material cross data between them, their results still accord with each other very well. Conclusions These three Monte Carlo codes are very consistent in calculating complex 3-D clinic head case, and DPM shows much more distinct superiority than others. |
