ABSTRACT:
The present invention has been made in order to decrease vibrations of gradient-magnetic-field coils in a magnetic apparatus for a magnetic resonance imaging diagnosis system so as to improve the image quality of magnetic resonance images.The magnetic apparatus includes: a superconductive electromagnet having pairs of superconductive coils for generating a uniform static magnetic field region, a pair of vacuum containers each for housing one of the superconductive coils of each of the pairs thereof, and a vacuum container connecting member for connecting the pair of vacuum containers; and a pair of gradient-magnetic-field coils for generating a gradient magnetic field having a gradient in a uniform static magnetic field region. In the magnetic apparatus, the pair of gradient-magnetic-field coils is connected by gradient-magnetic-field-coil-connecting members, and supporting members, which are connected either to the gradient-magnetic-field-coil-connecting members or to one of the gradient-magnetic-field coils, can be fixed to an installation base for the superconductive electromagnet.
