A dual-coil assembly for imaging two and more nuclei is tested with
phantoms containing a mixture of different nuclei, including 1H, 31P, 23Na and
13C. 1H and 23Na images and 23Na, 31P and 13C spectra are acquired. The coil
design shows promising results for multiheteronuclear imaging.
A –
1H image of a 3-section phantom filled uniformly with aqueous NaH2PO4
solution, B – 23Na image of a 3-section phantom. Section 1, “M” contains
aqueous NaH2PO4. Section 2, “R”, contains a solution of
NaCl and MnCl2. Section 3, “I”, is filled with the MnCl2 solution.
A –
1H butterfly-type coil model with tuning/matching capacitors. B – X-nuclei tuneable coil model. Feeding of the X-nuclei coil is
provided via inductive coupling to a small loop coil.
