Abstract
This paper discusses how to estimate scatter when performing motion correction of PET data. It concentrates on head movement, but some results are valid for non-rigid motion as well. We show that rigid motion affects scattered events differently then unscattered events. This has consequences for the scatter estimation procedure. We show with simulations, phantom measurements and patient data that our proposed method obtains fully quantitative motion-corrected PET images.
