The
first experimental realization of the multi-coil concept allowed improved
shimming of the mouse brain at 9.4 Tesla. The field shapes that can be
generated with a set of circular, electrical coils are shown to be much
better suited to compensate for the multitude of strong, localized and complex
magnetic field distortions apparent in the mouse brain than the conventional,
low order spherical harmonic functions used so far.
