SYSTEM AND APPARATUS FOR COMPENSATING FOR MAGNETIC FIELD DISTORTION IN AN MRI SYSTEM |
| 摘要 |
A magnet apparatus for a magnetic resonance imaging system, the magnet apparatus includes a cylindrical vacuum vessel, a closed loop cooling system disposed within the vacuum vessel and a cylindrical thermal shield disposed between the vacuum vessel and the closed loop cooling system. A set of passive compensation coils are disposed within the vacuum vessel and used to compensate for magnetic field distortion caused by mechanical vibrations within the magnet apparatus. |
