Synopsis

Keywords: High-Field MRI, High-Field MRI, RF arrays, transcieve coils, SCC coilThe recently proposed shielded-coaxial-cable (SCC) coils are intrinsically highly decoupled elements. Their suitability in multichannel transceiver arrays at ultra-high field was successfully demonstrated in 7T arrays. In this work, we investigated the single element and array properties of SCC coils at 9.4T. We simulated the SCC element and compared its properties (B1+, SAR) with those of a conventional loop coil. Subsequently, we fabricated eight SCC coils and investigated their coupling properties when placed in various configurations. SCCs at 400MHz provided similar B1+ and SAR efficiency, but generated ~25% less SAR10g,max . SCC performed well in different array configurations.
