Abstract

The invention relates to a coil configuration for Nuclear Magnetic Resonance (NMR) imaging, comprising a pair of coils (10B, 11B) driven by currents of opposite direction and a further coil (12B) lying in a plane of essentially zero magnetic flux. In a particular embodiment, the pair of coils has a crossed ellips geometry. The use of multiple coils can increase the signal to noise ratio compared to a larger coil that has the same field of view.
