Magnetic resonance apparatus comprising a superconducting shielding magnet. |
摘要 |
<p>In a magnetic resonance apparatus comprising a superconducting magnet system (1) for generating a steady magnetic field there is also included a superconducting shielding coil system (22) in order to compensate for magnetic field variations induced in the magnet by external magnetic flux variations. The shielding coil system (22) comprises coil sections (24) of different diameter. <IMAGE></p> |
