Abstract

Background: Auditing the treatment planning system (TPS) software for a radiotherapy unit is of paramount importance in any radiation therapy department. A Plexiglas phantom was proposed to measure the ionization of ⁶⁰Co high dose rate (HDR) source and compare dose points in the planning system for auditing and verifying TPS.

Methods: Auditing was performed using a Plexiglas phantom in an end-to-end test, and relative dose points were detected by a farmer-type ionization chamber and compared with the relative dose of similar points in TPS. The audit results were determined as pass optimal level (<3.3%), pass action level (between 3.3% and 5%), and out of tolerance (>5%).

Results: The comparison of the collected data revealed that 80% of the measured values were ≤5% in the pass level, and 20% of the points were out of tolerance (between 5% and 6.99%).

Conclusion: This study documented the appropriateness of the dosimetry audit test and this phantom design for the HDR brachytherapy TPS.

60Co近距离放射治疗计划系统审计测试的设计。

背景:对放射治疗单位的治疗计划系统(TPS)软件进行审核是任何放射治疗部门至关重要的工作。提出了一种有机玻璃模体，用于测量60Co高剂量率(HDR)源的电离度，并比较计划系统中的剂量点，用于审计和验证TPS。方法:端到端实验采用有机玻璃模体进行听析，农民式电离室检测相对剂量点，并与TPS中相似点的相对剂量进行比较。审核结果确定为通过最优水平(5%)。结果:对采集到的数据进行比较，80%的测量值在合格水平≤5%，20%的点超出公差范围(在5% ~ 6.99%之间)。结论:本研究证明了HDR近距离放疗TPS的剂量学审计试验和模体设计的适用性。
