SYSTEM AND APPARATUS FOR COMPENSATING FOR MAGNETIC FIELD DISTORTION CAUSED BY MECHANICAL VIBRATIONS IN AN MRI SYSTEM |
摘要 |
<p>A magnet apparatus for a magnetic resonance imaging system, the magnet apparatus includes a vacuum vessel, a helium vessel disposed within the vacuum vessel and a thermal shield disposed between the vacuum vessel and the helium vessel. A set of passive compensation coils are disposed within the vacuum vessel or the helium vessel and used to compensate for magnetic field distortion caused by mechanical vibrations within the magnet apparatus.</p> |
