ABSTRACT:
In the MRI apparatus of the present invention, a reinforcing member is firmly provided so as to enhance the rigidity strength of two connecting tubes connecting upper and lower cryostats, thereby suppression of vibration caused by a gradient magnetic field coil and suppression of variation of static magnetic field can be realized. Further, in the MRI apparatus of the present invention, the reinforcing member is provided in upper and lower portions of the connecting tubes of the vacuum vessels, thereby suppression of vibration caused by the gradient magnetic field coil and suppression of variation of static magnetic field can be realized. Further, in the MRI apparatus of the present invention, the reinforcing member is provided in upper and lower parts of the vacuum vessels, thereby suppression of vibration caused by the gradient magnetic field coil and suppression of variation of static magnetic field can be realized.
