A novel two-dimensional (2D) coil-signature-based phase cycled correction method has been developed for Nyquist artifact removal in echo planar imaging (EPI). Our method uses already available coil sensitivity information, without requiring extra reference scans, to correct 2D phase errors and can be applied equally well to single-shot and multi-shot EPI. Our results show that the developed method can effectively reduce Nyquist artifacts in EPI data acquired using a variety of acceleration schemes, such as through-plane Multi-band Imaging (MB) and in-plane parallel SENSitivity Encoding Imaging (SENSE).
