Varian 2300C 直线加速器6 MV X线的蒙特卡罗模拟

Simulating Varian 2300C 6 MV X Beam by Monte Carlo Code

摘要: 摘要: 利用先进的蒙特卡罗治疗头模拟程序BEAMnrc，依据商家提供的详细设计资料，集成多项优化模拟参数，对医用直线加速器射线束传输部分进行了模拟，获得与测量数据一致的模拟结果。对复杂多叶光栏模型进行了建模，模拟了非规则野的剂量分布，以用于后续研究工作。 Based on the detail head structure designing provided by the manufacture, the ray transmission of VARIAN Clinic 2300C 6 MVX beam was simulated by Monte Carlo code, BEAMnrc. To accelerate the simulation efficiency, multiple optimized parameters were optimized. The simulated and the measured data were well coincident. The dose distribution of a complicated irregular field formed by MLC (MultiLeaf Collimators) was simulated, which are the base for further research work.
