提供了一种用于设计医用电子直线加速器(linac) X射线均整过滤器的方法,并将其用于电子束辐射系统的优化过程之中。采用Monte Carlo模拟计算方法,提供了2个真实的国产医用电子直线加速器的辐射研究成果:BJ-20加速器的15 MV X射线辐射系统和BJ-14加速器的12 MeV电子束辐射系统。使用传统方法对上述成果进行了验证。
A method for designing a linac X-ray homogenizer filter is provided and used in the optimization of electron beam radiation systems. Monte Carlo simulation method is used to provide the radiation results of two real domestic medical electron linear accelerators: 15 MV X-ray radiation system of BJ-20 accelerator and 12 MeV electron beam radiation system of BJ-14 accelerator. The above results have been validated using traditional methods.
