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 with correcting and applying plural gradient magnetic fields for phase encode and with continuously inverting a gradient magnetic field for readout after one nuclear magnetic excitation. Each of the plural gradient magnetic fields for phase encode has an intensity set so as to compensate an influence of an eddy current distributing spatially adaptively to each of imaging positions. The image generating unit generates image data based on the echo signals.
