Title:
【発明の名称】磁気共鳴イメージング装置の静磁場均一度安定化方法
Document Type and Number:
Japanese Patent JP2860682
Kind Code:
B2
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.
