Patent ID: 8483457

Claim:
A magnetic resonance imaging (MRI) apparatus comprising: an MRI system having a plurality of gradient coils positioned about a bore of a magnet, and a radio-frequency (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: implement a scan sequence configured to elicit scan data, wherein the scan sequence comprises an echo planar imaging (EPI) sequence configured to elicit the image data; acquire the scan data; manipulate the scan data to determine a first plurality of phase errors in the image data responsible for a Nyquist ghost, wherein the manipulated scan data is free of navigator echo data; remove the first plurality of phase errors from the image data; and reconstruct an image based on the image data having the first plurality of phase errors removed therefrom.
