Abstract
The present application relates to a magnetic resonance imaging system comprising: a magnetic resonance imaging device comprising a cylindrical gradient coil apparatus, a radio frequency coil apparatus configured to transmit radio frequency signals at a first frequency, and a first shielding apparatus comprising a first shielding layer arranged radially between the gradient coil apparatus and the radio frequency coil apparatus; and a patient table device comprising a table portion configured for a patient to lie on it, and a second shielding apparatus arranged around at least a portion of the table portion, wherein when the magnetic resonance imaging device is engaged with the patient table device, the first shielding apparatus is in electrical contact with the second shielding apparatus to form a cutoff waveguide which is capable of cutting off radio frequency signals at frequencies below a second frequency, the second frequency being greater than the first frequency.
