1. A method for correcting distortion in magnetic resonance imaging, comprising the steps of: acquiring k-space data in a plurality of data readout directions, and converting the k-space data into a plurality of images, each comprised of pixels, with each pixel having a pixel value, and at least some of said images exhibiting geometric distortion; creating a pixel shift map for each of said images; correcting the geometric distortion in respective images in said plurality of images that exhibit geometric distortion, according to the respective phase shift map created for each respective image exhibiting geometric distortion, thereby obtaining geometric distortion-corrected images; and combining all of said geometric distortion-corrected images.
