Claim One:
1. A method for using navigators for inter-scan motion correction during imaging of a subject with a magnetic resonance imaging device, the method comprising: performing an anatomical localizer scan of a region of interest within the subject to identify one or more anatomical landmarks defining orientation of a surrounding field-of-view in the region of interest; performing an inter-scan motion reference scan of the region of interest to acquire a reference inter-scan dataset indicating a location of a reference navigator in the region of interest; performing a plurality of scans of the region of interest within the subject to acquire k-space data, wherein, prior to one or more of the plurality of scans, a motion correction process is performed comprising: performing an inter-scan motion tracking scan to acquire a tracking inter-scan dataset indicating an updated location of the reference navigator in the region of interest, determining an estimation of inter-scan patient motion based on a comparison between the reference inter-scan dataset and the tracking inter-scan dataset, and updating the field-of-view relative to the one or more anatomical landmarks in the region of interest based on the estimation of inter-scan patient motion; and generating one or more images of the region of interest using the k-space data acquired with each of the plurality of scans.
