Abstract:
1. A magnetic resonance imaging apparatus comprising: a gradient magnetic field application unit configured to apply a gradient magnetic field to an object to be examined placed in a static magnetic field; a radio-frequency magnetic field pulse application unit configured to apply a radio-frequency magnetic field pulse that excites magnetization of the object at a predetermined flip angle; a measurement unit configured to measure the magnetic resonance signals produced from the object; a control unit configured to control operation of the gradient magnetic field application unit, radio-frequency magnetic field pulse application unit and measurement unit, wherein the control unit further comprises a quasi-stationary state generation unit configured to control operation of the gradient magnetic field application unit and radio-frequency magnetic field pulse application unit, so as to generate the quasi-stationary state having the magnetic resonance signal which has the value lower than a predetermined threshold value within a predetermined time period after the radio-frequency magnetic field pulse application unit applies the radio-frequency magnetic field pulse.
