Dosimetry of small fields (SF) is vital for the success of highly conformal techniques. IAEA along with AAPM recently published a code of practice TRS-483 for SF dosimetry. The scope of this paper is to investigate the performance of three different detectors with 10 MV with-flatting-filter (WFF) beam using TRS-483 for SF dosimetry and subsequent commissioning of the Eclipse treatment planning system (TPS version-13.6) for SF data. SF dosimetry data ( beam-quality TPR 20,10 (10) , cross-calibration, beam-profile, and field-output-factor ( F.O.F )) measurements were performed for PTW31006-pinpoint, IBA-CC01 and IBA-EFD-3G diode detectors in nominal field size (F.S) range 0.5 × 0.5cm 2 to 10 × 10 cm 2 with water and solid water medium using Varian Truebeam linac. However, Eclipse-TPS commissioning data was acquired using IBA-EFD-3G diode, and absolute dose calibration was performed with FC-65G detector. The dosimetric performance of t...

使用 IAEA TRS-483 剂量测定协议测量 10 MV 光子束的小场输出因子并在 Eclipse TPS 调试中实施

小场 (SF) 的剂量测定对于高度保形技术的成功至关重要。IAEA 与 AAPM 最近发布了用于 SF 剂量学的 TRS-483 操作守则。本文的范围是研究使用 TRS-483 进行 SF 剂量测定的具有 10 MV 带平坦滤光片 (WFF) 光束的三种不同探测器的性能，以及随后调试用于 SF 的 Eclipse 治疗计划系统（TPS 版本 13.6）数据。对 PTW31006-pinpoint、IBA-CC01 和 IBA-EFD-3G 进行了 SF 剂量学数据（光束质量 TPR 20,10 (10)、交叉校准、光束轮廓和场输出因子 (FOF)）测量标称视场尺寸 (FS) 范围为 0.5 × 0.5cm 2 至 10 × 10 cm 2 的二极管探测器，使用 Varian Truebeam 直线加速器，具有水和固体水介质。但是，Eclipse-TPS 调试数据是使用 IBA-EFD-3G 二极管获取的，使用FC-65G检测器进行绝对剂量校准。t的剂量学性能...
