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 patient support system is provided. The patient support system includes a support table including a first end and a second end. The patient support system also includes a patient support coupled to the support table and configured to support a subject during an imaging procedure, wherein a top surface of the patient support is angled relative to a bottom surface of the patient support to position a portion of the subject to be imaged to be orthogonal to an imaging scan plane while the patient support is extended from the second end.
