MRI system utilizing supplemental static field-shaping coils

A magnetic resonance imaging system ( 10 ) includes a superconducting magnet ( 14 ) that generates a static magnetic field. A gradient coil assembly ( 50 ) with an associated patient bore enclosure ( 18 ) and a gradient coil ( 52 ) that generates a gradient magnetic field in the patient bore ( 18 )....

More Information
Summary:A magnetic resonance imaging system ( 10 ) includes a superconducting magnet ( 14 ) that generates a static magnetic field. A gradient coil assembly ( 50 ) with an associated patient bore enclosure ( 18 ) and a gradient coil ( 52 ) that generates a gradient magnetic field in the patient bore ( 18 ). A static field-shaping coil ( 11 ) resides between the superconducting magnet ( 14 ) and the patient bore ( 18 ) and supplements the static magnetic field.
