放射性粒子植入术的布源方式及放射剂量学研究进展

Research advances in spatial distribution of seeds and radiation dosimetry of radioactive seed implantation

放射性粒子植入技术的核心是精准性,包括粒子布源精准性和放射剂量学精准性两方面。目前临床应用的主要布源方式为个体化3D打印模板布源及扇形布源,在放射剂量学控制方面主要是通过蒙特卡洛算法及持续低剂量照射BED公式。本文对上述内容进行综述,为进一步提高放射性粒子植入术的规范化治疗提供参考。

Accuracy is the primary concern of radioactive seed implantation.Currently,radioactive seed has been implanted using individualized 3D printing template or fan-shaped distribution technique,and dose distribution is calculated by Monte Carlo algorithm or continuous low dose BED formula.This paper summarizes related aspects mentioned above in order to improve the quality of brachytherapy treatments.
