<p>A magnetic resonance imaging apparatus and the magnet apparatus thereof comprise plural pairs of magnetic field generation sources, arranged face to face with each other, for forming a magnetic field space 3; and magnetic field homogeneity adjusting apparatuses 17 and 18 for providing homogeneity adjustment of the magnetic field formed in the magnetic field space 3. The magnetic field homogeneity adjusting apparatuses 1 7 and 18 contain a plurality of tapped holes 24 for installing a magnetic field homogeneity adjusting member 26 of smaller volume in a plate -formed tray made of a non-magnetic substance; and a plurality of mounts 25 for installing the magnetic field homogeneity adjusting member 27 of greater volume, these mounts being formed over the area containing a plurality of through -holes for permitting installation of a magnetic field homogeneity adjusting member 26 of smaller volume, whereby major magnetic field adjusting work can be performed independently of minor magnetic field adjusting work.</p> |
