摘要

为了解决近距离放射治疗中可能出现的粒子源丢失和手术人员的辐射暴露等问题,提出了一种注射针型质子诱导单色x射线源。本文讨论了针周围剂量分布的实验结果与蒙特卡罗数值模拟的比较。给出了不同源设计的仿真结果,作为设计优化的第一步。

Experimental and numerical study of dose distribution around a syringe needle-type proton-induced X-ray source for radiotherapy
A syringe needle-type proton-induced monochromatic X-ray source was proposed to solve the issue that could occur in practical brachytherapy, such as loss of seed sources and radiation exposure to surgical staff. This paper discusses comparison between experimental results and a Monte Carlo numerical simulation of the dose distribution around the needle. Some simulation results for different source designs are presented as a first step of the design optimization.
