Claim Text:
1. A method comprising: acquiring, with a detector comprising a plurality of rings defining corresponding slices, emission event data of an object of interest; determining an axial segment size for a plurality of segments to be independently analyzed for motion independent of each other; determining, with one or more processing units, using the emission event data, an amount of motion for each of the plurality of segments independently of each other, wherein each segment comprises at least one of the slices and corresponds to less than an axial field of view (AFOV) of the detector; performing, with the one or more processing units, motion mitigation for segments for which the amount of motion satisfies a threshold to provide motion mitigated data, and not performing motion mitigation for segments for which the amount of motion does not satisfy the threshold to provide non-mitigated data; reconstructing, with the one or more processing units, an image using the motion mitigated data and the non-mitigated data; and displaying the image on a display.
