1. A magnetic resonance (MRI) apparatus comprising: an MRI system having a plurality of gradient coils positioned about a bore of a magnet, and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images; and a computer programmed to: acquire a plurality of three-dimensional (3D) MR data sets, each 3D MR data set acquired using a central transmit frequency and a central receive frequency set to an offset frequency value that is distinct for each 3D MR data set; reconstruct a subimage for each of the plurality of 3D data sets; apply a de-blurring correction to each of the subimages; and generate a composite image based on the subimages corrected for de-blurring.
