ABSTRACT:
A magnetic resonance imaging apparatus includes a data acquisition unit and an image generating unit. The data acquisition unit acquires echo signals by echo planar imaging which generates the echo signals by applying plural phase-encoding gradient magnetic field pulses and by repeatedly inverting a readout gradient magnetic field after one nuclear magnetic resonance (NMR) excitation. Each of the plural phase-encoding gradient magnetic field pulses has an intensity set so as to compensate an influence of spatially distributed eddy currents to each of the spatial imaging positions. The image generating unit generates MRI data and an image based on the acquired echo signals.
