An intrinsically dual tuned single element antenna
providing a congener resonance behavior is utilized
within a four channel setup for combined 23Na and 1H MRI
at 7T. The antenna is based on the composite
right-/left-handed transmission line technique with
short circuited line terminations. The array shows a
homogeneous B1-field distribution for both resonances
while the specific absorption rate is evenly distributed
along the antennas.
