Multiplexed Eighty Channel PMT List-Mode Data Acquisition System for 27–511 keV Gamma Ray Imaging

摘要

We have developed an 80-channel readout system for gamma cameras which acquires PMT signals and stores them in list-mode format on a computer. The system combines low noise and a large signal range to handle PMT signals from a wide range of SPECT and PET tracers simultaneously (27 to 511 keV).
