Abstract:
1. A magnetic resonance imaging apparatus comprising: an exciting and acquisition device configured to excite spins within a subject; a plurality of parallel receiver systems configured to acquire, by applying a reduced field-of-view, imaging echoes generated by the excited spins along with navigator echoes; a first correcting device configured to conduct phase correction on said imaging echoes based on at least one of said navigator echoes; a first image producing device configured to produce an intermediate image based on said phase-corrected imaging echoes from said plurality of parallel receiver systems; a separate generating device configured to generate a sensitivity matrix corresponding to and from said plurality of parallel receiver systems; a second correcting device configured to phase-correct matrix data in said sensitivity matrix; and a second image producing device configured to produce an output image with a full field-of-view based on said intermediate image and said phase corrected sensitivity matrix.
