A Dual-Tuned Half Volume Coil for 13C(1H) MRS: Two Open Coils in One

In 13C(1H) studies a coil system that resonates at both the frequencies of 13C and 1H is required. We present here a single-unit, dual-tuned, half-volume coil that is based upon the open coil design (half birdcage). To make it dual-tuned, each alternate leg was tuned to one of the two frequencies alternately and a trap circuit was placed in each leg to block current at the unwanted frequency. The efficacy of the coil was verified on the human calf at 3 T.
