    摘要: A magnet, such as a closed, superconductive, magnetic-resonance-imaging (MRI) magnet includes a main coil, a magnetizable article, and a shielding coil positioned radially outward from the main coil and magnetizable article. Two magnetizable members are positioned radially outward from the main coil and magnetizable article and radially inward from the shielding coil to supplement the strength, and increase the homogeneity of, the magnetic field created, at least in part, by the main coil and magnetizable article and to supplement the shielding provided, at least in part, by the shielding coil.

    摘要: A magnetic resonance imaging (MRI) magnet includes different-diameter, longitudinally-proximate, first and second coil form segments. First and second superconductive coils are wound, respectively, around the first and second coil form segments. A first spacer ring is attached to the first coil form segment and longitudinally abuts a lateral side of the first superconductive coil, and a second spacer ring circumferentially surrounds and is attached to the second coil form segment and longitudinally abuts a lateral side of the second superconductive coil. Two or more circumferentially-spaced-apart plate members are attached to, and extend radially outward from, the first and second spacer rings.

    摘要: A superconducting device, such as a superconducting rotor for a generator or motor. A vacuum enclosure has an interior wall surrounding a cavity containing a vacuum. A superconductive coil is placed in the cavity. A generally-annularly-arranged, thermally-conductive sheet has an inward-facing surface contacting generally the entire outward-facing surface of the superconductive coil. A generally-annularly-arranged coolant tube contains a cryogenic fluid and contacts a generally-circumferential portion of the outward-facing surface of the sheet. A generally-annularly-arranged, thermally-insulative coil overwrap generally circumferentially surrounds the sheet. The coolant tube and the inward-facing surface of the coil overwrap together contact generally the entire outward-facing surface of the sheet.

    摘要: A planar magnetic resonance imaging (MRI) magnet having a superconductive coil assembly including a toroidal-shaped coil housing which surrounds a bore, has a longitudinal axis, and contains at least three concentric, annular-shaped superconductive coils coaxially aligned with the axis. The coils produce a magnetic resonance imaging volume having a center located outside the bore. Preferably, the bore is generally completely filled with magnetic material, and the magnetic resonance imaging volume is located completely outside the bore which provides for improved patient and physician access during MRI-guided biopsy as well as during MRI imaging.
