  • Superconducting magnet coil support structure
    Patent number: 7013553
    Abstract: A superconducting magnet coil support structure (20) includes a solid body (21) having an exterior side (24), an interior portion (26), and an interior side (28). The interior portion has a base (36) that is formed of a first resin material. The exterior side (24) has multiple spacers (32) and multiple pockets (34) with dimensions that correspond to dimensions of a superconducting magnet (14). The spacers (32) are coupled to the base (36) and are formed of a second resin material. The exterior side (24), the interior portion (26), and the interior side (28) include varying width material.

  • Method for winding an embedded b-zero coil
    Patent number: 6892440
    Abstract: A method for winding on embedded b-zero coil maintains the integrity of superconducting main coil and the b-zero wire during coil winding and during normal operation of a superconducting MRI magnet. The b-zero coil is co-wound with an aluminum overwrap while the aluminum overwrap is being wound onto the superconducting MRI coil. The two-wire geometries are selected such that the height or thickness of the aluminum overwrap is greater than or equal to the height or thickness of the b-zero coil wire. The b-zero coil wire sits in a cavity that is created by adjacent turns.

  • Superconducting magnetic resonance imaging magnet assembly and method with reverse wire channel orientation
    Patent number: 6633215
    Abstract: A superconducting magnetic resonance imaging magnet assembly is provided. The assembly includes an axial imaging bore to receive patients and a coil housing surrounding the axial bore. A main magnet coil assembly is disposed within the housing. The main magnet coil assembly includes a plurality of main magnet coils to produce a magnetic field. At least three pairs of superconductive coils are provided. In one aspect, each of the coils in at least one of the pairs comprises a superconductor wire carrying an electric current in a direction opposite to the direction of current carried by the coils of another of the superconductive pairs. The superconductor wire comprises a superconductor core and a stabilizer having a channel. The wire is wound so that the channel has a radially outward facing opening.
