A Three-Element H-1-P-31 Dual-Tuned Array For Magnetic Resonance Spectroscopy At 4.7 T

This work describes the construction and testing of a three-element, double-tuned receive array and transmit coils for P-31-H-1 spectroscopy and imaging. The receive coils were geometrically-decoupled, single-loop surface coils and the transmit coils were concentric saddle coils. The coils were used to examine a physiologically-modeled CNC-milled phantom. The receive coil array was able to improve SNR while also providing gross localization of the H-1 and P-31 signals.
