The advancement of irradiation technology has increased the demand for quality control of radiation therapy equipment. Consequently, the number of quality control items and required personnel have also increased. However, differences in the proportion of qualified personnel to irradiation techniques have caused bias in quality control systems among institutions. To standardize the quality across institutions, researchers should conduct mutual quality control by analyzing the quality control data of one institution at another institution and comparing the results with those of their own institutions. This study uses failure mode and effects analysis (FMEA) to identify potential risks in 12 radiation therapy institutions, compares the results before and after implementation of mutual quality control, and examines the utility of mutual quality control in risk reduction. Furthermore, a cost-effectiveness factor is introduced into FMEA to evaluate the utility of mutual quality control.
辐射技术的进步增加了对放射治疗设备质量控制的需求。因此，质量控制项目的数量和所需人员也有所增加。然而，合格人员比例与辐射技术的差异导致各机构质量控制系统存在偏差。为了使各机构的质量标准化，研究人员应通过分析另一个机构的一个机构的质量控制数据并将结果与其自身机构的结果进行比较来进行相互质量控制。本研究使用失效模式和效应分析（FMEA）来识别12个放射治疗机构中的潜在风险，比较相互质量控制实施前后的结果，并检验相互质量控制在降低风险方面的效用。此外，将成本效益因素引入FMEA以评估相互质量控制的效用。
