| 520 | _ | _ | |a Proton magnetic resonance imaging (MRI) can be combined with signals from non-proton nuclei (X-nuclei) to provide metabolic information. Double-resonant coils are often used for X-nuclei MR studies where the proton element is employed for scout imaging and B 0 shimming. This work describes the development of a new double-resonant coil capable of operating at both proton and X-nuclei frequencies.The proposed design extends the wheel-and-spoke coil, which allows for quadrature drive, by adding an extra ring outside the coil to achieve double-resonance. Furthermore, in order to maximise SNR by increasing the filling factor, the shape of the coil has been modified to a helmet style making it suitable for brain applications.The performance of the double-resonant helmet coil was evaluated by simulation and MR measurements. The helmet coil was successfully tuned to the 1H/31P resonance frequencies of a 3T MR scanner, with high isolation between the two quadrature ports. MR measurements of a phantom were carried out, and the averaged sensitivity of the double-resonant helmet coil over the whole phantom was found to be higher than that of the conventional double-tuned birdcage coil at both frequencies. |
