摘要
An imaging system (36) includes a Positron Emission Tomography (PET) scanner (38) and one or more processors (52). The Positron Emission Tomography (PET) scanner (38) which generates event data including true coincident events and scatter events, the event data includes each end point of a line of response (LOR) and an energy of each end point. The one or more processors (52) are programmed to generate (72) a plurality of activity map and attenuation map pairs based on the true coincident events, and select (76) an activity map and an attenuation map from the plurality of activity and attenuation map pairs based on the scattered events.
