The development of ultra-high-field (UHF) magnetic resonance imaging (MRI) and spectroscopy imaging (MRSI) technologies improves sensitivity and spatial resolution for biomedical and clinical applications. However, the limited inherent signal-to-noise ratio (SNR) is still challenging, especially for pushing spatiotemporal resolution even at UHF. Previous studies have shown that high dielectric constant (HDC) materials could provide a new RF engineering solution for the challenge. In this study, we introduce a novel microstrip transmission line (MTL) transceiver array that uses HDC material as substrate, and significantly improves the RF transmission (B1+) and reception (B1-) fields and SNR for 1H imaging application at 7T.
