Patent ID: 8547101

Claim:
A magnetic resonance imaging device comprising magnetic field generating means for generating a static magnetic field, a radio frequency magnetic field, and a gradient magnetic field, respectively, a detection means for detecting magnetic resonance signals generated from a subject placed in the static magnetic field, a calculation means for creating a magnetic resonance spectrum from the magnetic resonance signals and displaying the spectrum on a display, and a measurement control means for controlling operations of the magnetic field generating means, the detection means, and the calculation means to perform measurement, wherein: the measurement control means comprises: a selective excitation means for localizing and selecting a first region that generates the magnetic resonance signals with the radio frequency magnetic field and the gradient magnetic field, and a steadying means for thermally equilibrating nuclear magnetization in one or more second regions different from the first region with the radio frequency magnetic field and the gradient magnetic field during the localization of the first region by the selective excitation means, the first region and the second regions are each specified with perpendicularly intersecting three slices, one or two slices among the three slices specifying each region are common, and the slices of not common are located completely different position, and the steadying means steadies nuclear magnetization in the second regions by using a radio frequency magnetic field of which phase is different by 180 degrees from that of the radio frequency magnetic field used by the selective excitation means.
