A magnetic resonance system uses a shielded superconducting magnet to
produce a dsv useful for specialist imaging in an overall short magnet
system at field strengths 1.5 Tesla and above. The magnet includes at
least a first central coil C1, which has a length of at least 25% of the
overall length of the magnet, and is used in concert with a series of
symmetric primary coils, at least one set of which carry current in a
direction opposite to that of the central coil. Force balancing is
advantageously used in the design of the coils. The primary coils are
shielded by at least one shielding coil, which carries current in a
direction opposite to the majority of the primary coils. The magnet
resonance system can be used for orthopedic imaging.
