本研究在联影攻关研制国产新一代全数字PET/CT中，为全数字高分辨 PET 探测器核心部件的自主研发及 PET/CT 系统架构集成提供可靠性设计与失效分析工作。完成了关键部件结构可靠性设计工作，使用FMEA方法分析关键部件的失效模式，计算风险顺序数，对后果严重度大于9或者风险顺序数大于100的故障模式提出改进措施。完成了PET探测器HALT测试、CT探测器仿真测试以及CT探测器模块环境测试等，验证
Determine mean time to failure (MTTF) for the following system components in specific environments of operation: ; and Provide substitute system components
ABSTRACT The geometric process (GP) is a stochastic process that was an extension of the renewal process. It was introduced by Lam (1988) in 1988 with an intention to model the failure process of a re
In nuclear facilities, predictive maintenance is essential to sustain safety, reliability, and availability, particularly for ageing components that are sensitive to downtime. Conventional strategies
