An apparatus and method are provided to correct motion artifacts in magnetic resonance imaging (MRI) data by obtaining magnetic resonance imaging (MRI) data, the MRI data including imaging segments and corresponding navigator segments, each imaging segment sampled over a respective regions of two or more regions of a k-space grid, one of the navigator segments being selected as a reference navigator segment； generating, for each imaging segment of the imaging segments, a respective phase map based on the reference navigator segment and a corresponding navigator segment of the each imaging segment； applying the respective phase maps to the corresponding imaging segments to generate corrected imaging segments； averaging the corrected imaging segments in k-space to generate averaged imaging segments； and reconstructing an MRI image based on the averaged imaging segments.
