PROBLEM TO BE SOLVED: To provide MRI device comprising a means for obtaining excellent image while improving comfort in subject, in which generation of eddy current magnetic field due to leaked magnetic field and variable magnetic field due to magnetic change are suppressed and broad photographing space is provided in an iron magnetic pole upon generation of inclined magnetic field.SOLUTION: There is provided MRI device comprising a static magnetic field magnet having a magnet as magnetic pole and inclined magnetic field coil. The magnet as magnetic pole opposing to photographing space is constructed with approximately disk shaped iron magnetic pole, approximately ring shaped iron magnetic pole and magnetic pole pieces of tile shaped silicon steel plate. The magnetic pole pieces of tile shaped silicon steel plate is laminated on surface of the disk shaped iron magnetic pole. The disk shaped iron magnetic pole is divided in circumference direction and insulated each other with insulation or gap.SELECTED DRAWING: Figure 1 |
