摘要：
A method for estimating the start time of an electronic pulse generated in responseto a detected event, for example the start time for pulses received in responseto photon detection in positron emission tomography, includes providing a detectorthat detects an external event and generates an electronic analog pulse signal.A parameterized ideal curve shape is selected to represent analog pulse signalsgenerated by the detector. Upon receiving an analog pulse signal, it may be filtered,and then digitized, and normalized based on the area of the digital signal. Usingat least one point of the normalized digital pulse signal, a curve from the parameterizedideal curve shape is selected, that best represents the received analog pulsesignal, and the selected curve is used to estimate the pulse start time.
