Abstract:
1. A method of serially transferring annihilation information in a compact positron emission tomography (PET) scanner used to obtain an input function from at least a portion of a human body, comprising the steps of: inputting a first time pulse on a first channel, the first channel being one of a plurality of channels, the first time pulse comprising a position representing a time-of-occurrence of a first annihilation event; generating a first time signal, the first time signal representing a time-of-occurrence of the first time pulse, the first time pulse being asynchronous to a clock signal; generating a first address signal, the first address signal comprising a first address, the first address representing the first channel, the first address signal being synchronous to the clock signal; generating a first channel signal, the first channel signal comprising the first time signal and the first address signal; and outputting the first channel signal serially.
