    Abstract: A method implemented using at least one processor includes receiving time-varying image dataset generated by a medical imaging modality. The image dataset corresponds to a bed position and is affected by quasi-periodic motion data. The method also includes applying a signal decomposition technique to the time-varying image dataset to generate a plurality of dataset components and a plurality of motion signals. The method also includes determining reference data based on the time-varying image dataset, wherein the reference data is representative of a direction of the quasi-periodic motion. The method further includes deriving polarity of each of the plurality of motion signals based on the reference data to generate a plurality of sign corrected motion signals. The method also includes determining a gating signal corresponding to the bed position based on at least one of the plurality of sign corrected motion signals.

    Abstract: A method includes receiving Emission Tomography (ET) data of a subject from an ET/Computed Tomography (CT) scanner. The method further includes generating a first motion signal corresponding to a first bed position of the ET/CT scanner from the received ET data and determining whether the first motion signal indicates a periodic motion. The method also includes calculating a first time period from the first motion signal in response to determining that the first motion signal indicates the periodic motion and sending a first acquire notification to the ET/CT scanner to acquire Cinematographic (CINE) Computed Tomography (CT) data from the first bed position based on the first time period.
