Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, Non-Array RF Coils, Antennas & Waveguides, Flexible RF CoilsForm-fitting coil designs demand highly flexible coils such as twisted pair or coaxial transmission line resonators. Both of these designs and respective interfacing circuits were investigated as receive-only coils at 7 T. Similar signal-to-noise ratio and active detuning performance compared to a standard copper wire coil were demonstrated in bench and MRI experiments.
