1. A computer-implemented method for compensating for motion of a subject during a magnetic resonance imaging (MRI) scan of the subject, the method comprising:

  • configuring one or more processors to perform an operation comprising;

    receiving k-space data from the MRI scan of the subject, wherein the k-space data comprises frequency domain data for generating a graphical image of the subject, and wherein the frequency domain data includes a plurality of rows including a first row of data acquired at a first point in time during the MRI scan and a second row of data acquired at a second point in time during the MRI scan;

    receiving motion information captured for the subject by a capturing technique during the MRI scan;

    determining a translational motion of the subject between the first point in time and the second point in time based on the received motion information; and

    reducing a search space for motion correction using the determined translational motion, wherein the search space includes a set of potentially occurring motions of the subject between the first point in time and the second point in time.
