ABSTRACT:
A magnetic resonance imaging system is provided in which the two contradictory requirements, i.e., enhancing the feeling of being not confined by enlarging the subject-insertion space and decreasing magnetomotive force of the superconductive coils by bringing the superconductive coils as close as possible to a subject, can be met in a good balance.In a magnetic resonance imaging system that includes a superconductive electromagnetic device for generating a static magnetic field to be applied to a subject, a gradient-magnetic-field coil for forming a gradient magnetic field by tilting the magnetic-field strength of the static magnetic field, and a radio-frequency coil for transmitting a radio-frequency magnetic field to the subject and then receiving nuclear magnetic-resonance signals from the subject, a vacuum container for the superconductive electromagnetic device thereof has a recess; the gradient-magnetic-field coil and the radio-frequency coil thereof are accommodated in the recess; and a cosmetic cover that is fit into the recess and is supported by the wall surfaces of the recess is included therein.
