摘要
该研究结合上海市第六人民医院在用MR的临床使用工况,将MR部件分为扫描Ⅰ型和扫描Ⅱ型。同时,结合MR部件的主失效应力,将MR的分为动力学部件和电热学部件。该研究给出了系统可靠性指标确定、系统可靠性分配、部件可靠性指标实现、系统可靠性预计和系统可靠性验证一整套的磁共振(以下简称"MR")系统可靠性指标与实现方法。同时,该研究也给出了可靠性预计和可靠性验证的方法,并给出了基于临床使用数据统计的MR系统MTBF计算方法。
Combined with the clinical use condition of MR in use in Shanghai Sixth People’s Hospital, MR components are divided into scanning type Ⅰ and scanning type Ⅱ. At the same time, combined with the main loss force of MR components, the research divides MR components into dynamic components and electric thermal components. In this study, a complete set of MR system reliability indexes and implementation methods are given, including system reliability index determination, system reliability allocation, component reliability index realization, system reliability prediction and system reliability verification. At the same time, this study also gives the methods of reliability prediction and reliability verification, and gives the MTBF calculation method of MR system based on clinical use data statistics.
