Synopsis

Keywords: Non-Array RF Coils, Antennas & Waveguides, Non-Array RF Coils, Antennas & Waveguides, Superconducting material, DecouplingA promising strategy to tackle the issue of decoupling High-Temperature Superconducting (HTS) surface coils during emission is to exploit nonlinearities of the HTS coil electromagnetic response. In this work, we present the first Magnetic Resonance Images acquired with a decoupled HTS surface coil and the required coil’s features to obtain these images. The change of the HTS coil Q-factor values leads to different decoupling levels (DL) of the HTS coil and the presence or absence of B1 artifacts on the images.
