Summary:The invention provides a scattering single-photon event processing method and system and a PET system. The scattering single-photon event processing method comprises the steps that a single-photon event output by a photon counting detector is acquired; and inputting the single-photon event into a pre-trained scattering single-photon event processing model to identify whether the single-photon event is a scattering single-photon event. According to the method, scattering identification of the single-photon event is directly carried out, identification of the scattering photons is carried out to the detector end in advance, compared with existing coincidence event scattering identification, the single-photon event data of the detector end is more accurate, data processing is carried out more essentially, accurate, comprehensive and automatic identification of the scattering single-photon event is achieved, and the detection efficiency is improved. And a foundation is laid for subsequent scattering correction an
