The purpose of this study was to determine if medical linear accelerators (linac) produced by the same manufacturer exhibit operational consistency within their subsystems and components. Two linacs that were commissioned together and installed at the same facility were monitored. Each machine delivered a daily robust quality assurance (QA) irradiation. Linacs and their components operate consistently, but have different operational parameter levels even when produced by the same manufacturer and commissioned in series. These findings have implications on the feasibility of true clinical beam matching.
本研究的目的是确定同一制造商生产的医用直线加速器（直线加速器）在其子系统和组件内是否表现出操作一致性。对两台一起调试并安装在同一设施中的直线加速器进行了监测。每台机器每天都进行一次严格的质量保证（QA）照射。直线加速器及其组件运行一致，但即使由同一制造商生产并串联调试，其操作参数水平也不同。这些发现对真正的临床射束匹配的可行性具有影响。
