Claim One:
1. A magnetic resonance imaging (MRI) method performed by an MRI system having a primary field magnet, a plurality of gradient coils, a radiofrequency (RF) transmit coil, a plurality of RF receiving coils, and control circuitry configured to control the gradient field coils, the RF transmit coil, and the plurality of RF receiving coils, comprising: randomly undersampling points in a first portion of a k-space plane outside of a center of the k-space plane using at least the control circuitry, the primary field magnet, the plurality of gradient coils, and the RF transmit and receiving coils to obtain sampled data points representative of a subject of interest; computing, for each sampled data point in the first portion of the k-space plane, data representative of the subject of interest at a corresponding complex conjugate location in a second portion of the k-space plane using the control circuitry to obtain computed data points representative of the subject of interest; sampling additional points that are symmetric about themselves and in the first portion of the k-space plane when a mathematical origin of the k-space plane used for computation of the data at the complex conjugate locations does not correspond to the center of the k-space plane using at least the control circuitry, the primary field magnet, the plurality of gradient coils, and the RF transmit and receiving coils to obtain additional sampled data points representative of the subject of interest; computing, for each additional sampled data point, data representative of the subject of interest at a corresponding complex conjugate location using the control circuitry to obtain additional computed data points representative of the subject of interest; generating a map corresponding to the k-space plane by compiling the sampled and computed data points using the control circuitry; and storing the map in memory circuitry associated with the control circuitry.
