基于纳米粘土的放射性荧光凝胶(NC-RFG)用于验证高剂量率(HDR)近距离放射治疗中的源位置和剂量分布。剂量反应证实线性度高达 60 Gy。源位置检测精度≤0.3 mm,Ir-192源附近的剂量分布与蒙特卡罗模拟吻合良好。 NC-RFG 有望成为适合评估 HDR 近距离放射治疗剂量分布的质量保证工具。
A nanoclay-based radio-fluorogenic gel (NC-RFG) was used to verify the source position and dose distribution in high-dose-rate (HDR) brachytherapy. The dose response confirmed linearity up to 60 Gy. The source position could be detected with an accuracy of≤ 0.3 mm, and the dose distribution near the Ir-192 source showed good agreement with the Monte Carlo simulation. NC-RFG can be expected to be a quality assurance tool suitable for the evaluating the dose distribution in HDR brachytherapy.
