Comparison of PMT PET detector and DPC PET detector approach. For PMT PET, incident photons are converted to visible light via interaction with scintillators coupled with multiple PMTs to generate and multiply electronic signals for further Anger-logic positioning decoding which exhibits significant dead time. For DPC PET, 1:1 coupling of scintillator and digital detector directly channels lights from a crystal to its ‘own’ detector with a digital signal output that is virtually dead time free
