本文探讨了Octavius 4D系统用于容积旋转调强放射治疗（VMAT）三维剂量验证的稳定性。比较分析了semiflex电离室和Octavius 729探测器阵列在6 MV、10 MV射束下对射野大小、剂量线性、剂量率线性和射野输出因子的响应。测量观察Octavius 4D系统旋转过程中角度仪示值与机架角的...
This paper investigates the stability of the Octavius 4D system for three-dimensional (3D) dose verification in volumetric modulated arc therapy (VMAT). A comparative analysis was conducted on the responses of the semiflex ionization chamber and Octavius 729 detector array to field size, dose linearity, dose rate linearity, and output factor under 6 MV and 10 MV radiation beams. Measurements were performed to observe the readings of the goniometer and the gantry angle during the rotation of the Octavius 4D system
