A positron emission tomography imaging system includes a detector configured to detect radiation emitted from an object to be examined, a data processing apparatus configured to reconstruct image data for positron emission tomography diagnosis from detection data obtained from the detector, and a user terminal configured to obtain desired information by operating the detector and the data processing apparatus. The detector includes a detection part having a plurality of detection elements configured to detect the radiation emitted from the object to be examined for every designated timing, and an event information file generation part configured to generate an event information file based on the detection data obtained from the detector.
