The present invention relates to a Compton imaging apparatus and a single photon emission and positron emission tomography system comprising the Compton imaging apparatus and, more specifically, to a Compton imaging apparatus based on a single scintillator and a single photon emission and positron emission tomography system including the Compton imaging apparatus. The Compton imaging apparatus according to the present invention may reconstruct a Compton image based on the single scintillator composed of a plurality of scintillation cells. Thus, the Compton imaging apparatus of the present invention is cheaper than any other Compton imaging apparatuses and has an excellent time resolution such that the Compton imaging apparatus can be used even in a high-radiation area. Also, the single photon emission and positron emission tomography system using the Compton imaging apparatus can improve radiation detection efficiency and an image resolution, to thereby improve image quality.
