Abstract
A magnetic resonance imaging device includes a control unit configured to set a plurality of frequency bands within a predetermined frequency range. A subject is caused to be irradiated with a high-frequency magnetic field pulse having one of the frequency bands from a transmission unit. A reception unit is caused to receive a nuclear magnetic resonance (NMR) signal generated by the subject. An image generation unit is caused to generate an image from the NMR signal while changing the frequency band. A plurality of images corresponding to the plurality of frequency bands are obtained, and a composite of the plurality of images is obtained. The frequency bands are set so that adjacent frequency bands partially overlap each other. A bandwidth of the frequency bands is narrowest for the frequency band including a specific frequency within the frequency range, and widens in a direction away from the specific frequency.
