Matrix-decoding Nyquist ghosting correction for SMS EPI. (a), (c) Eddy current effects and field inhomogeneities cause echo shift and phase mismatch between odd and even echoes; (b), (d) These effects correspond to linear phase ramps along x. (a), (b) Matrix-decoding correction with arbitrary ky-kz undersampling patterns; (c), (d) with special undersampling patterns where kz is fully sampled.
