摘要 依据美国医用物理学家协会(AAPM)在TG-43U1推荐的剂量学参数计算方法,针对671l型(3M)125I短程治疗源,用蒙特卡罗方法计算剂量率常数,并与相关数据进行了比较。在此基础上,计算研制的新型125I-103Pd混合源的剂量学参数,如剂量率常数、径向剂量函数和各向异性函数,计算结果对混合源的实验研究和应用具有一定指导意义。 According to dose calculation formula recommended by AAPM TG-43U1, dose rate constant of Model 6711 125I brachytherapy source was calculated by Monte Carlo meth- od. The calculation results were in good agreement with TG-43U1. Then, dose rate con- stant,radial dose function and anisotropy function of new hybrid PdI source were calculated by Monte Carlo method. Empiric equations were obtained for radial dose function.
