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
ABSTRACT In the development of new designs for systems or improvement of existing ones, the search for effective methods of reliability allocation is fundamental to achieve the minimum requirements. T
In many reliability applications, degradation of products has to be measured destructively, and destructive degradation tests are a useful tool to evaluate product reliability. Previous studies common
The dataset file contains data of different reliability demonstration tests (RDTs). For this dataset, an RDT is a failure-based test for a product with Weibull distributed failure times (due to a sing
