Reference-free EPI Nyquist ghost correction using annihilating filter-based low rank hankel matrix for K-space interpolation

Abstract

MR measurements from an EPI sequence produce Nyquist ghost artifacts that originate from inconsistencies between odd and even echoes. By converting the ghost correction problem to an interpolation problem from uniformly down-sampled even and odd phases, here we propose a single pass reference free ghost artifact removal algorithm. Specifically, our… (More)
