MAGNETIC RESONANCE IMAGING DEVICE AND MAGNETIC RESONANCE IMAGING METHOD

摘要

According to one embodiment, an MRI apparatus (20) includes a first acquisition unit, a second acquisition unit and a correction unit (100). The first and second acquisition units produce a plurality of echo signals by performing echo signal acquisition sequence of EPI including application of a gradient magnetic field in a phase encoding direction, and acquire the plurality of echo signals as first and second template data, respectively. The second acquisition unit acquires the second template data under a sequence in which start timing of application of a gradient magnetic field in a readout direction is shifted from the case where acquisition of the first template data is performed. The correction unit (100) corrects phase error included in the echo signals by using the first and second template data.
