abstract = {A double-tuned 1H/19F coil using PIN-diode switches was
developed and its performance evaluated. The is a key
difference from the previous developments being that this
design used a PIN-diode switch in series with an
additionally inserted inductor in parallel to one of the
capacitors on the loop. The probe was adjusted to 19F when
the reverse bias voltage was applied (PIN-diode OFF), whilst
it was switched to 1H when forward current was flowing
(PIN-diode ON).S-parameters and Q-factors of single- and
double-tuned coils were examined and compared with/without a
phantom on the bench. Imaging experiments were carried out
on a 9.4 T preclinical scanner. All coils were tuned at
resonance frequencies and matched well. It is shown that the
Q-ratio and SNR of double-tuned coil at 19F frequency are
nearly as good as those of a single-tuned coil. Since the
operating frequency was tuned to 19F when the PIN-diodes
were turned off, losses due to PIN-diodes were substantially
lower resulting in the provision of excellent image quality
of X-nuclei.},
