SYSTEM FOR MAGNETIC FIELD DISTORTION COMPENSATION AND METHOD OF MAKING SAME |
| 摘要 |
A system and method for magnetic field distortion compensation includes a cryostat for a magnetic resonance imaging (MRI) system. The cryostat includes a vacuum casing having a vacuum therein. A cryogen vessel is disposed within the casing, the vessel having a coolant therein. A thermal shield is disposed between the vacuum casing and the cryogen vessel. An eddy current compensation assembly is disposed within the casing. The eddy current compensation assembly includes a plurality of electrically conductive loops formed on one of the vacuum casing, the cryogen vessel, and the thermal shield and constructed to mitigate vibration-induced eddy currents in the MRI system. |

1. A cryostat for a magnetic resonance imaging (MM) system, the cryostat comprising:
a vacuum casing having a vacuum therein; a cryogen vessel disposed within the casing, the cryogen vessel having a coolant therein; a thermal shield disposed between the vacuum casing and the cryogen vessel; and an eddy current compensation assembly disposed within the vacuum casing, the eddy current compensation assembly comprising a plurality of symmetrical compensation coils formed on one of the vacuum casing, the cryogen vessel, and the thermal shield. |
