| Zusammenfassung: | Systems, methods and apparatus are provided through which a partially elongated field-of-view 302 in a magnetic resonance imaging system is generated either by an asymmetric primary coil 104 or a conventional symmetrical primary coil with a supplementary high odd-order shim 500 and 600 that elongates the field-of-view towards one end of the bore. For significantly increased efficiency, the high odd-order shim can evoke specific parts of the primary coil by injecting additional current and/or subtracting current from specific turns, as required. |
