During the use of PET systems、 the system performance may change due to factors such as component performance、 and even affect normal use. Therefore、 it is necessary to promptly understand the performance changes of the system and make adjustments in a timely manner. The performance detection of PET system time-of-flight technology in existing technologies mainly relies on image reconstruction of collected data、 that is、 using the system to collect data and reconstruct images of the tested body or active model with known activity distribution、 and judging the time-of-flight performance from the reconstructed image quality (such as image uniformity). The implementation process of this method is complex and often requires attenuation and scattering correction of corresponding CT images (PET-CT equipment)、 which is not conducive to implementation due to high time and economic costs Therefore、 it is necessary to propose a new method and device for detecting the time-of-flight performance of positron emission tomography systems、 which can conveniently and efficiently detect the system's time-of-flight performance
