Abstract:
1. A method for generating a magnetic resonance (MR) image, the method comprising: acquiring a first k-space data set from each of a plurality of RF coils, the first k-space data set including calibration data in a center region of k-space and randomly undersampled data in an outer region of k-space; generating a fully randomly sampled k-space data set for each RF coil by removing a portion of the calibration data from the k-space data set; applying a compressed sensing reconstruction technique to the fully randomly sampled k-space data set of each RF coil to generate an aliased image for each RF coil; applying a Fourier transform to the aliased image of each RF coil to generate a uniformly undersampled k-space data set for each RF coil; generating a second k-space data set for each RF coil by inserting the portion of the calibration data; applying a parallel imaging reconstruction technique to the second k-space data set of each RF coil to synthesize unacquired data for each RF coil; combining the second k-space data set and the synthesized data for each RF coil to generate a complete k-space data set for each RF coil; and generating an image based on the complete k-space data sets.
