PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device capable of suppressing deterioration of uniformity of a magnetic field.SOLUTION: The magnetic resonance imaging device includes a substantially circular cylinder shaped coil mechanism having a static magnetic field magnet 101 generating a static magnetic field in a space inside the circular cylinder, and an inclined magnetic field coil 103 which is arranged inside the circular cylinder of the static magnetic field magnet and generates an inclined magnetic field. In the coil mechanism, a magnetic body is supported independently from the inclined magnetic field coil, and arranged near the center of the coil mechanism in the longitudinal direction along a circumferential direction of the substantially circular cylinder shape.COPYRIGHT: (C)2015,JPO&INPIT【課題】磁場の均一性の劣化を抑制することができる磁気共鳴イメージング装置を提供する。【解決手段】磁気共鳴イメージング装置は、円筒内側の空間に静磁場を発生する静磁場磁石101と、前記静磁場磁石の円筒内側に配置され、傾斜磁場を発生する傾斜磁場コイル103とを含む略円筒形状のコイル機構を備える。また、前記コイル機構のうち、前記傾斜磁場コイルとは独立に支持され、前記コイル機構の長軸方向の中央付近に、略円筒形状の周方向に沿うように、磁性体が配置される。【選択図】図5
