Applying statistical process control (SPC) to intensity‐modulated radiotherapy (IMRT)/volumetric modulated arc therapy (VMAT) patient‐specific quality assurance (PSQA) program was recommended by the American Association of Physics in Medicine Task Group 218 report, but a comprehensive analysis of PSQA processes with non‐normal distributions is lacking. This study investigates SPC and process capability analysis (PCA) methods for non‐normal IMRT/VMAT PSQA processes.

非常规的容积调制电弧疗法针对患者的质量保证过程的统计过程控制和过程能力分析。

美国医学物理学会任务组218报告建议将统计过程控制（SPC）应用于强度调制放疗（IMRT）/体积调制弧光治疗（VMAT）患者特定的质量保证（PSQA）程序，但缺乏对具有非正态分布的PSQA流程的分析。这项研究调查了非常规IMRT / VMAT PSQA流程的SPC和流程能力分析（PCA）方法。
