A vertical B.sub.0 temporally constant magnetic field is defined between a pair of pole faces (12, 14) that are interconnected by a C-shaped ferrous magnetic flux path (16). A quadrature radio frequency coil array (50) is disposed in a plane orthogonal to the B.sub.0 field. The coil array includes a...http://www.google.com/patents/US5578925?utm_source=gb-gplus-sharePatent US5578925 - Vertical field quadrature phased array coil system
