摘要
A PET apparatus includes a detector array including individual detectors which receive radiation events from an imaging region. A movement controller controls at least one of relative longitudinal movement between a subject support and the detector array and circumferential movement between the detector array and the subject. A time stamp processor assigns a time stamp to each received radiation event. A list mode event storage buffer stores time stamped events. An event verification processor screens for coincidentally received radiation events locations at which each pair of corresponding coincidentally received events defining a line of response. A reconstruction processor reconstructs valid events into an image representation of the imaging region.
