Abstract：In recent years, Silicon Photomultiplier (SiPM) technology has been greatly developed. Due to its good magnetic resistance characteristic and low breakdown voltage, SiPM is gradually replacing Photodiodes and photomultiplier tube in many applications. Time-of-flight Positron Emission Tomography (TOF-PET) is a nuclear medicine imaging system that often uses SiPM as a detector. The readout technology of the system is mainly divided into pre-amplification technology and time amplitude detection technology. This paper introduces several typical pre-amplification circuits, including voltage amplification, transimpedance amplification and chargesensitive amplification. For time information detection, this paper introduces two common timing interpolation methods. In the energy information measurement, the time-over-threshold approach in this application is introduced.
