| 中文摘要: |
| 硼中子俘获治疗（BNCT）利用中子与肿瘤细胞中富集的硼发生特异性俘获反应，可以定向杀死癌细胞。为了验证中子放疗计划的准确性，保障患者的治疗效果，需要在治疗前进行剂量验证，即对比分析实验照射剂量与计划剂量。目前，BNCT剂量测量方法主要包括电离室法、热释光法、活化法等点剂量测量方法，基于胶片的二维剂量测量方法，以及基于凝胶剂量仪的三维剂量测量方法。本文总结了国际上BNCT剂量验证方法的进展，讨论了这些方法的发展前景。 |
| 英文摘要: |
| To summarize the progress in BNCT dose verification method in the world and discusses their development prospects. Boron neutron capture therapy (BNCT) utilizes the specific capture reaction between the neutrons and boron drugs enriched in tumor cells to selectively kill tumor cells. In order to verify the accuracy of the radiotherapy plan and ensure the therapeutic effect on patients, it is necessary to measure the dose before treatment and compare the experimental radiation dose with the planned dose. The current BNCT dose measurement method mainly include point dose measurement method based on ionization chambers, thermoluminescence dosimeters and activation foils, two-dimensional dose measurement method based on films, and three-dimensional dose measurement method based on gel dosimeters. |
