Abstract: Emission event data of an object of interest is acquired with a detector comprising a plurality of rings defining corresponding slices. Also, an amount of motion for each of a plurality of segments is determined with one or more processing units, wherein each segment corresponds to less than an axial field of view (AFOV) of the detector. Further, motion mitigation is performed for segments for which the amount of motion satisfies a threshold to provide motion mitigated data, and not performed for segments for which the amount of motion does not satisfy the threshold to provide non-mitigated data. An image is reconstructed using the motion mitigated data and the non-mitigated data, and the image is displayed on a display.

Abstract: Methods and systems are provided for analyzing a respiratory motion waveform acquired during acquiring imaging data with a molecular imaging device. In one embodiment, a method comprises acquiring imaging data with a molecular imaging apparatus, analyzing a respiratory motion waveform acquired during the acquiring imaging data, and applying gating to the acquired imaging data based on the analyzed respiratory motion waveform. In this way, gating may be applied to the acquired imaging data in order to generate an image for medical diagnosis with increased image quality and accuracy.

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.
