Zusammenfassung:Embodiments provide a computer-implemented method, system and article of manufacture of deriving a motion signal from imaging data, including: acquiring a time-series of three dimensional image volumes; generating the motion signal based on the time-series of three dimensional image volumes; and obtaining an optimal gate to correct for temporal variations in an amplitude of the motion signal, wherein the optimal gate is the smallest amplitude range covering a pre-determined fraction of acquisition time of the motion signal.
