    Abstract: PURPOSE: A PET device and a signal process method of the PET device are provided to improve the sensitivity of a PET device by increasing a counting rate. CONSTITUTION: A PET device comprises a pre-amplification unit(220), an ADC(Analog to Digital Converter, 230) and a signal processing unit(240). The pre-amplification unit receives a detected gamma-ray signal and amplifies the rise time of the output waveform under 100ns. The ADC changes the signal, amplified by pre-amplification unit, into digital signal. The signal processing unit receives the digital signal and stores the signal having the energy value, in which the photoelectric effect generates.
