摘要： A Magnetic Resonance Imaging (MRI) system is disclosed. The MRI system includes a cryogenic magnet assembly with a cryogenic vessel housing a superconducting magnet. Disposed radially inboard of the cryogenic magnet assembly are a gradient coil module and a plurality of room temperature steel rings proximate to the gradient coil module. A field of view is defined by at least the superconducting magnet, the gradient coil module, and the plurality of room temperature steel rings. In response to the superconducting magnet being energized, the room temperature steel rings create high order harmonics that serve to expand the magnetic field homogeneity FOV, and low order harmonics that tend to degrade the magnetic field homogeneity within the FOV. The low order harmonics are compensated for by the cryogenic magnet assembly.

摘要： A thermal barrier is introduced to a magnetic resonance imaging system between the patient bore and each of the gradient coil assembly and RF body coil assembly to maintain the temperature within the patient bore below a maximum operating temperature. This allows the RF body coils to run cooler and also provides a thermal barrier between the gradient coils and the patient bore. In one preferred embodiment, a hollow conductor structure is introduced to the RF body coils at a position between the gradient coils and the patient bore tube. In another embodiment, the hollow conductor structure replaces the flat copper strip of the prior art and itself functions as the RF body coils.
