Abstract
An RF coil assembly for an MRI system includes a resonator formed by a cylindrical shield and pairs of opposing conductive legs disposed symmetrically around a central axis and extending the axial length of the shield. One set of conductive leg pairs is tuned to operate at the Larmor frequency ofC and another set is tuned to operate at the Larmor frequency ofH. Drive circuitry operates the RF coil assembly to produceH spin magnetization which is transferred toC magnetization by the nuclear overhauser effect and to acquire MR data from theC spins. Multinuclear measurements can be made simultaneously at different Larmor frequencies.
