ABSTRACT:
A MRI apparatus includes a super-conducting magnet including a superconducting coil circuit having a super-conducting coil and a permanent current switch for controlling permanent current flowing through the super-conducting coil; at least one electrical circuit which is electrically connected to at least one electrical element and disposed at the outside of the super-conducting magnet; a gradient magnetic filed generating means; a high frequency magnetic field generating means; and shielded examination room which accommodates the super-conducting magnet. The apparatus further comprises means for interrupting noise current generated based on tomographic image measurement of the subject. Said means is disposed outside the super-conducting magnet and inside the shielded examination room while being inserted between the electrical circuit and the super-conducting magnet.
