Abstract
Method and apparatus of stabilizing uniformity of a static magnetic field in a magnetic resonance imaging apparatus, wherein before adjustment of uniformity of the static magnetic field and before each actual imaging operation, pulse-like gradient magnetic fields are applied to a static magnetic field generating magnetic circuit at a maximum output level of power supplies for generation of gradient magnetic fields so as to magnetize the static magnetic field generating magnetic circuit to constant magnetization intensity.
