Proliferation of high field scanners has made MRS of non-hydrogen elements more appealing. The need for access to deep brain regions justifies development of tools to help better understand the existing dual tune coils and provide guidance for their improvement. In this study, FDTD is used to characterize a dual tuned 31P/1H coil. Improvement in performance of the coil is demonstrated as a result of application of this technique in identification of the pure modes, interaction of the two segments of the coil, and its effect on detection of 31P in deep regions of a phantom.
