Abstract:
A magnetic resonance imaging apparatus includes an input unit, a data acquisition unit and an image generating unit. The input unit inputs information indicating a matter of which resonance frequency is a center frequency of an excitation pulse. The data acquisition unit acquires magnetic resonance data with obtaining a steady state free precession. Each of the plural excitation pulses has a transmission phase varying by a variation amount determined based on a difference between a resonance frequency and the center frequency. The image generating unit generates an image of the desired matter based on the magnetic resonance data.
