Abstract: Systems and methods to partially-gate PET data include acquisition of first data describing a plurality of coincidences detected during a scan of an object, each of the plurality of coincidences associated with a coincidence time and a line of response, acquisition of a motion signal associated with motion of the object during the scan, determination of lines of response which are associated with a region of the object, determination of time periods of region motion based on the motion signal, modification of the first data to remove coincidences which are associated with the determined lines of response and which are associated with a coincidence time during a time period of region motion, reconstruction of an image of the object based on the modified first data, and display of the image.

Abstract: Systems and methods to partially-gate PET data include acquisition of first data describing a plurality of coincidences detected during a scan of an object, each of the plurality of coincidences associated with a coincidence time and a line of response, determination of lines of response which pass through a region of the object, determination of time periods of motion of the region, modification of the first data to remove coincidences which are associated with the determined lines of response and which are associated with coincidence time during the determined time periods of motion of the region, reconstruction of an image of the object based on the modified first data, and display of the image.
