Abstract
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; and magnetic field homogeneity adjusting apparatusesandfor providing homogeneity adjustment of the magnetic field formed in the magnetic field space. The magnetic field homogeneity adjusting apparatusesandcontain a plurality of tapped holesfor installing a magnetic field homogeneity adjusting memberof smaller volume in a plate-formed tray made of a non-magnetic substance; and a plurality of mountsfor installing the magnetic field homogeneity adjusting memberof greater volume, these mounts being formed over the area containing a plurality of through-holes for permitting installation of a magnetic field homogeneity adjusting memberof smaller volume, whereby major magnetic field adjusting work can be performed independently of minor magnetic field adjusting work.
