Abstract: A method for producing an attenuation-corrected time-gated PET image comprising includes obtaining a baseline MR image and a cine MR image of a structure; registering the baseline MR image to the cine MR image to create an image transform; and generating a corresponding cine ACF matrix using the image transform, and time-correlating the ACF matrix to a time-gated PET data set to produce an attenuation-corrected time-gated PET image.

Abstract: A method for generating a Positron Emission Tomography (PET) image includes defining a scan window having a predetermined length along an examination axis of a PET imaging system, the scan window corresponding to a region of interest to be continuously scanned by the PET imaging system, defining at least two data bins corresponding to two separate scan regions within the scan window, defining a transition region that overlaps a portion of each of the separate scan regions within the scan window, the transition region having a width that is shorter than a length of the scan window, binning emission data acquired within the transition region into the two data bins, binning emission data acquired from outside the transition region into one of the two data bins, and reconstructing an image using the emission data in the two data bins.

Abstract: Exemplary embodiments of the present disclosure are directed to scheduling positron emission tomography (PET) scans for a combined PET-MRI scanner based on an acquisition of MR scout images of a subject. An anatomy and orientation of the subject can be determined based on the MR scout images and the schedule for acquiring PET scans of the subject can be determined from the anatomy of the subject. The schedule generated using exemplary embodiments of the present disclosure can specify a sequence of bed positions, scan durations at each bed position, and whether respiratory gating will be used at one or more of the bed positions.
