Claim One:
1. A method for correcting phase errors in multiple shot magnetic resonance imaging (MRI) data acquisition, the method comprising: acquiring diffusion-weighted MRI data using a plurality of shots, each shot acquiring uncorrected k-space data comprising an autocalibration region and at least one undersampled outer region; generating motion-corrected k-space data corresponding to the autocalibration region of each shot; generating a motion-corrected reference autocalibration region using at least a portion of the motion-corrected k-space data; calculating at least one set of coefficients based on a plurality of data points from the uncorrected k-space data and at least one data point from the motion-corrected reference autocalibration region; and synthesizing motion-corrected k-space data using the at least one set of coefficients.
