1. A magnetic resonance imaging method, comprising: randomly undersampling a first portion of a k-space plane; computing, for each randomly undersampled point in the first portion of the k-space plane, a second point at a corresponding complex conjugate location in a second portion of a k-space sampling pattern corresponding to a second portion of the k-space plane; sampling additional points in either the first portion or the second portion of the k-space plane that have not been sampled or computed; and computing, for each additional sampled point, a corresponding point at a corresponding complex conjugate location.
