This annotated pulse illustrates the flexibility of 2 GSPS WFS for TOF PET readout. WFS enables programmable definition of leading-edge timing and of integrated light collected by PMT, from a single data stream. Digital baseline restoration and shape-based pile-up detection help to preserve performance at high count rates. Integration time is programmable and may be adapted as a function of count rate. Waveform processing and system design are described in Section II.
