System and method for parallel magnetic resonance imaging

Abstract

A method for reconstructing a full k-space dataset using parallel magnetic resonance (MR) imaging technique is provided. The method includes acquiring, by a plurality of receiver coils, a set of first under-sampled k-space data, receiving a set of second partial or fully-sampled k-space data, respectively performing k-space interpolation of the set of the first under-sampled k-space data respectively acquired by each of the plurality of receiver coils, recovering respectively missing k-space lines of each of the set of first under-sampled k-space data using corresponding second partial or fully-sampled k-space data and corresponding first under-sampled k-space data, forming a plurality of full k-space datasets by respectively combining each of the set of first under-sampled k-space data and corresponding recovered missing k-space lines for each of the plurality of receiver coils, obtaining a plurality of fully-sampled images from the plurality of full k-space datasets, and combining images into a final image.
