Abstract
Systems, methods and apparatus are provided through which a partially elongated field-of-view in a magnetic resonance imaging system is generated either by an asymmetric primary coil or a conventional symmetrical primary coil with a supplementary high odd-order shim 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.
