Counter Rotating Current (CRC) pairs of loop-gap resonators are combined with planar pairs of loop-gap resonators to form networks of NMR local coils. A first embodiment is a quadrature probe in which a planar pair is sandwiched between the loop-gap resonators of the CRC pair. In a plurality of other...http://www.google.ca/patents/US4721913?utm_source=gb-gplus-sharePatent US4721913 - NMR local coil network
