| 摘要 |
<p>The present invention provides a cylindrical superconducting magnet system for use in magnetic resonance imaging. Axially aligned primary superconducting coils (30), are positioned within an outer vacuum chamber (OVC) (14). A thermal radiation shield (16) surrounds the primary superconducting coils, within the OVC. A primary gradient coil assembly is axially aligned with the primary superconducting coils and is located radially within the primary superconducting coils. The cylindrical superconducting magnet system also includes a secondary gradient coil assembly, radially positioned outside of the primary superconducting coils and mechanically attached to the primary gradient coil assembly.</p> |
