Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus capable of enhancing the symmetricalness of the magnetic characteristics when a gradient magnetic field is applied even if a magnetic circuit of a static magnetic field generating device is spatially asymmetrical.  <P>SOLUTION: A high magnetic permeability member 37 whose magnetic permeability is higher than the material constituting a pole plate 31 and a permanent magnet 38 are disposed between the pole plate 31 and a gradient magnetic field generating part 34. As the permanent magnet 38, such a permanent magnet as magnetized in the direction parallel to the static magnetic field of an imaging region 30 can be used. Accordingly, as the static field and the magnetic field generated by the permanent magnet 38 are superimposed on the whole high magnetic permeability member 37, the influence of the asymmetricalness of the static magnetic field can be reduced. Further, as the direction of magnetization of the permanent magnet 38 is parallel to that of the static magnetic field, the magnetization of the high magnetic permeability member can be turned toward the static magnetic field. As a result of these effects, the symmetricalness of the magnetic characteristics of the high magnetic permeability member can be enhanced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
