abstract = "We present our work toward implementing all-digital signal processing for Positron Emission Tomography (PET) event detection. In the conventional PET system, proper calibration and extending event processing axe challenging tasks due to the huge number of channels and multiplexing of input signals in the mixed-signal front-end. To alleviate such limitations, we have proposed a simple all-digital PET system utilizing digital signal processing (DSP) technologies for analyzing event pulses generated in PET. In this work, we implement a Gaussian shaper circuit for scintillation pulses, which followed by a moderate sampling rate Analog-to-Digital Converter (ADC). We also evaluate two DSP algorithms for extracting time information from the digitized pulse samples, and the two algorithms examined could generate a coincidence timing resolution of ∼2.4ns FWHM, by using a 125MSps sampling rate ADC.",
