Figure Lengend Snippet: (A) The prototypes of the 31P/1H double tuned and doubled matched (DODO) coil, control single frequency 31H and 31P coils, and the imaging setup. (B) The 31P/1H DODO S-parameter measurement (left panel) demonstrates excellent tuning and matching for both 1H and 31P frequencies; and the coil circuit diagram (right panel).

Article Snippet: The 8-ch 31 P/ 1 H DODO coil and the TEM volume coil were loaded with a head-shaped inorganic phosphate (Pi) phantom for acquiring proton density image and 31 P chemical shift imaging (CSI) on a Siemens MAGNETOM 7T scanner.

Techniques: Control, Imaging

Figure Lengend Snippet: (A) The top to bottom rows display the results of measurements based on the single-frequency control 1H or 31P coil (see Fig. 1A), illustrating RF transmit fields (B1+) for H and 31P, as well as signal-to-noise ratio (SNR) for 31P and the corresponding 31P CSI acquired at nominal 90-degree pulse flip angle. Noticeably, the 31P MRSI noise level for both DODO and control coils are similar. (B) Results of measurements obtained using the 1H/31P DODO coil.
