目的:探讨使用三维蓝水箱(BPH)扫描测量系统完成螺旋断层加速器设备的剂量分布检测.方法:使用BPH和OmniPro-Accept 7.5软件对螺旋断层加速器40.0 cm×1.0 cm、40.0 cm×2.5 cm及40.0 cm×5.0 cm三种射野下的百分深度剂量、射野横向截面和纵向截面射束离轴剂量分布进行数据采集,并将采集数据与厂商所给出的金标准进行比较,并对其两者差异进行分析.结果:不同深度处的百分深度剂量(PDD),无论在建成区域还是在其他深度处BPH测量的数据与金标准数据很好的吻合,差异

Objective: Discuss how to detect dose distribution of helical tomotherapy linear accelerator by using BPH three-dimensional water tank. Methods: Acquired percentage depth dose (PPD), in-plane and cross-plane in 40.0 cm×1.0 cm, 40.0 cm×2.5 cm and 40.0 cm×5.0 cm fields, respectively, of helical tomotherapy accelerator by BPH three-dimensional water tank and OmniPro-Accept 7.5 software. Compared acquired data with gold standard provided by manufacture and analyzed the differences between them. Results: For the PDD of different depth, data colle...
