This study aims to report the relevant issues concerning small fields in the commissioning of a TrueBeam STx for photon energies of 6MV, 10MV, 6FFF, and 10FFF. Percent depth doses, profiles, and field output factors were measured according to the beam model configuration of the treatment planning system. Multiple detectors were used based on the IAEA TRS-483 protocol as well as EBT3 radiochromic film. Analytical Anisotropic and Acuros XB algorithms, were configured and validated through basic dosimetry comparisons and end-to-end clinical tests.
本研究旨在报告 TrueBeam STx 在 6MV、10MV、6FFF 和 10FFF 光子能量调试中与小射野相关的问题。根据治疗计划系统的束流模型配置，测量了百分深度剂量、射野轮廓和射野输出因子。根据国际原子能机构 TRS-483 协议以及 EBT3 光致变色胶片，使用了多个探测器。通过基本剂量学比较和端到端临床测试对解析各向异性和 Acuros XB 算法进行了配置和验证。
