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 comprising receiving 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.
