| 摘要 |
A magnetic field generating system suitable for use in a magnetic resonance apparatus has mirror-symmetrical assemblies disposed at opposite faces of a supporting structure, each assembly having a pole plate located between a pulsed magnetic field excitation coil and a static magnetic field generating source. Each pole plate is formed by a number of pole plate segments that either electrically insulated from each other, or conduct between adjacent segments only at single points, without forming a conductive loop. Eddy current propagation is thereby suppressed.
