Superconducting magnetic resonance imaging magnet assembly and method with reverse wire channel orientation |
摘要 |
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. In another embodiment, low-aspect-ratio coils are used for at least one of the pairs of superconductive coils with the outer diameter coil portion comprising a superconductor core and a stabilizer channel having a radially outward facing opening.</PTEXT>
