Abstract

The improvement of time resolution in time-of-flight positron emission tomography (TOF-PET) relies on the development of scintillation materials and photodetectors. With the introduction of Cherenkov TOF-PET, higher requirements have been placed on the intrinsic timing performance of photodetectors. Our team has proposed a Cherenkov Radiator Window Photomultiplier tube (CRW-FPMT) that uses the Cherenkov radiator directly as the light window, which eliminates the boundary between the scintillator and the photodetector for fast time resolution. This paper mainly discusses the factors influencing its time resolution and optimizes it to achieve a single photon time resolution of 27.2 ps.

提高切伦科夫辐射窗光电倍增管的时间分辨率

飞行时间正电子发射断层扫描（TOF-PET）时间分辨率的提高有赖于闪烁材料和光电探测器的发展。随着切伦科夫 TOF-PET 的引入，对光电探测器的内在时间性能提出了更高的要求。我们的团队提出了一种直接使用切伦科夫辐射器作为光窗的切伦科夫辐射器窗口光电倍增管（CRW-FPMT），它消除了闪烁器和光电探测器之间的边界，从而实现了快速时间分辨率。本文主要讨论了影响其时间分辨率的因素，并对其进行了优化，以实现 27.2 ps 的单光子时间分辨率。
