球水模体中辐射剂量密度分布的模拟研究

Simulation of the distribution of radiation dosage density in water ball

利用欧洲粒子物理实验室开发的一个包容大量探测器描述和模拟工具的软件系统(GEANT3)模拟计算、分析球状水模体模型中γ射线的辐射剂量密度分布与病灶大小及放射源特性的关系。

This article analyzed the distribution of radiation dosage density in water ball, the size of malignent region and the character isties of radiation source were concerned as main factors. All works were based on the numeric simulation by GEANT3 system.
