ABSTRACT:
For the purpose of enabling parallel imaging even when a navigator echo is used to phase-correct an imaging echo, the present invention involves: exciting spins within a subject to acquire an imaging echo generated by the excited spins along with a navigator echo, with a reduced field-of-view via a plurality of receiver systems; conducting phase correction on the imaging echo based on the navigator echo; producing an intermediate image based on the phase-corrected imaging echo from each of the plurality of receive systems; generating a sensitivity matrix for the plurality of receiver systems; correcting the phase of matrix data in the sensitivity matrix; and producing an image with a full field-of-view based on the intermediate image and the phase-corrected sensitivity matrix.
