1. A system for performing parallel image reconstruction of undersampled image data in k-space, the system comprising:

  • an imaging apparatus configured to generate first imaging data of an image area and to generate second imaging data of the image area;

    a computer-readable medium having computer-readable instructions therein, the instructions comprisingreceiving a defined partitioning of a k-space region into a plurality of segments;

    identifying a segment of the plurality of segments wherein data is sampled at less than a Nyquist rate;

    sampling the generated first imaging data at the Nyquist rate;

    calculating a reconstruction coefficient for at least a portion of the identified segment using the sampled first imaging data;

    sampling the identified segment of the generated second imaging data at less than the Nyquist rate;

    predicting a value for a missing k-space sample in the identified segment using the calculated reconstruction coefficient and the sampled second imaging data; and

    defining an image of the image area using the predicted value and the sampled second imaging data; and

    a processor operably coupled to the computer-readable medium and configured to execute the instructions.
