Abstract
In this study, through the analysis of the composition of domestic large radioactive medical equipment PET/CT and the characteristics of each subsystem, combing the vulnerable spots, according to the standard requirements of PET/CT for 10 years in its service life, we research the PET/CT service life's effectiveness. Firstly, this study introduces the concept of service life, the relationship between service life and risk analysis, the pivotal system composition of PET/CT, the importance of reliability of each component, the traditional test method to verify its reliability is researched. This study suggests a test procedure and method to prove the reliability of various components of PET/CT equipment during the service life. This method is described in detail, and the specific test process in practical engineering application is discussed, which proves that it is beneficial to ensure the effectiveness of PET/CT during the service life.
