Abstract
A radio frequency coil includes a non-cylindrical conformal surface () that substantially conforms with a magnetic resonance subject. A plurality of conductor loops () are disposed in or on the non-cylindrical conformal surface. The plurality of conductor loops are configured to produce a substantially uniform Bi field in the magnetic resonance subject responsive to energizing at a Bi frequency. Optionally, a plurality of load-compensating conductor loops () are disposed in or on a compensatory non-cylindrical conformal surface () that substantially conforms with a magnetic resonance subject. The plurality of load-compensating conductor loops are configured to produce a non-uniform Bi field that compensates for a loading Bi non-uniformity caused by the magnetic resonance subject. Moreover, the coil may comprise switching means for switching the coil between a first mode of operation (e.g. a volume transmit mode) and a second mode of operation (e.g. a phased array reception mode).
