Abstract
A method for MRI inter-scan motion correction includes performing (i) an anatomical localizer scan of a region of interest (ROI) to identify anatomical landmarks defining orientation of a surrounding field-of-view (FOV); (ii) an inter-scan motion reference scan of the ROI to acquire a reference inter-scan dataset indicating a reference navigator location in the ROI; and (iii) scans of the ROI to acquire k-space data. Prior to one or more of the scans, a motion correction process is performed that includes (a) performing an inter-scan motion tracking scan to acquire a tracking inter-scan dataset indicating an updated reference navigator location; (b) determining an estimation of inter-scan patient motion based on a comparison between the reference inter-scan and tracking inter-scan datasets; and (c) updating the FOV relative to the landmarks based on that estimation. Images of the ROI may be generated using the k-space data acquired with each of the scans.
