    Abstract: A method is provided that includes acquiring, with a detector comprising a plurality of rings defining corresponding slices, emission event data of an object of interest. The method also includes determining, with one or more processing units, an amount of motion for each of a plurality of segments, wherein each segment corresponds to less than an axial field of view (AFOV) of the detector. Further, the method includes 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. Also, the method includes reconstructing an image using the motion mitigated data and the non-mitigated data. The method also includes displaying the image on a display.

    Abstract: A method is provided that includes acquiring, with a detector defining a field of view (FOV), emission imaging data of an object over the FOV. The method also includes determining, with one or more processing units, a volume of interest (VOI) of the emission imaging data, wherein the VOI defines a volume smaller than an imaged volume of the object. Further, the method includes performing, with the one or more processing units, a multivariate data analysis on the VOI to generate a waveform for the VOI. Also, the method includes determining, with the one or more processing units, an amount of motion for at least the VOI based on the waveform. The method further includes displaying, on a display unit, at least one of the amount of motion or an image reconstructed based on the emission imaging data.

    Abstract: A method for selecting data to reconstruct a three-dimensional (3D) image of a subject of interest includes acquiring a 3D emission dataset of the subject of interest, acquiring a respiratory signal of the subject of interest, the respiratory signal including a plurality of respiratory cycles, and calculating a respiratory profile using the respiratory signal. The method further includes, for each respiratory cycle, generating a gating window, calculating a minimum total squared difference (TSD) between a plurality of phases in the respiratory profile and the same plurality of phases in the respiratory cycle, and positioning the gating window based on the TSD values calculated, and reconstructing a 3D image using only the emission data within the plurality of gated windows. A system and non-transitory computer readable medium are also described herein.

    Abstract: A method is provided that includes acquiring, with a non-emission imaging acquisition unit, non-emission modality imaging information of an object. The method also includes acquiring, with an emission imaging acquisition unit, emission modality imaging information of the object. Also, the method includes selecting at least one portion of the emission modality imaging information for motion assessment and/or correction based on the non-emission modality imaging information and a clinical task. Further, the method includes performing motion correction on the emission modality imaging information based on the selected at least one portion of the data to provide motion-aware emission modality imaging information, and reconstructing an image using the motion-aware emission modality imaging information.
