A magnetic resonance imaging apparatus includes a first data acquisition
unit, a second data acquisition unit and an image data generating unit.
The first data acquisition unit acquires first data from a slice to be a
target after a first delay time from a reference of a first heart rate in
synchronized with an electrocardiogram. The second data acquisition unit
acquires second data from the slice after a second delay time from a
reference of a second heart rate which is different from the first heart
rate. The image data generating unit generates image data with image
reconstruction processing using the first data and the second data.
