Open MRI magnet having a support structure

摘要

An open magnetic resonance imaging (MRI) magnet having first and second spaced-apart superconductive coil assemblies connected by spaced-apart structural posts each having a first end portion attached to the coil form of the first coil assembly and a second end portion attached to the coil form of the second coil assembly. Each toroidal shaped coil form has radially spaced-apart inner and outer generally cylindrical shells and has longitudinally spaced-apart inner and outer annular plates each attached to the inner and outer cylindrical shells. A superconductive coil surrounds, and is attached to, the outer surface of the outer cylindrical shell.
