Magnetic resonance imaging apparatus having a pair of a first magnet device
and a second magnet device for generating a magnetostatic field, the pair of magnet
devices being installed opposite each other across an examination space for accommodating
an examinee; a gradient-field generating device; a high-frequency field generating
device; and a yoke for combining the first and second magnetic devices to guide
magnetic fluxes generated by the first and second magnetic devices to thereby form
a closed magnetic circuit, wherein the yoke includes a first plate member fixed
to a first magnet device, a second plate member fixed to a second magnet device
and one or more support-post members interconnecting the first plate member and
the second plate member, each of the first and second plate members and support-post
members includes a plurality of segments formed in a predetermined shape.
