Patent ID: 7723987

Claim:
A magnetic resonance imaging system comprising: an RF pulse application section which applies a high-frequency electromagnetic field (RF) pulse to a measuring object; a signal detection section which measures a magnetic resonance signal from the measuring object caused by the RF pulse; a gradient magnetic field application section which applies a gradient magnetic field for adding spatial modulation to the magnetic resonance signal; a calculation section which reconstructs an image from the magnetic resonance signal measured by the signal detection section; and a control section which controls operations of the RF pulse application section, the signal detection section, the gradient magnetic field application section and the calculation section, wherein the control section performs control so as to apply a first RF pulse having a plurality of substantially parallel excitation planes together with a first gradient magnetic field, apply a second RF pulse together with a second gradient magnetic field in a direction different from the direction in which the first gradient magnetic field is applied and controls the RF pulse application section and the gradient magnetic field application section so as to apply a third gradient magnetic field in a direction perpendicular to both the first gradient magnetic field and the second gradient magnetic field for a period during which the signal detection section measures the magnetic resonance signal.
