Keywords: Non-Array RF Coils, Antennas & Waveguides, Non-Array RF Coils, Antennas & WaveguidesThis abstract proposes a standardized setup and four standardized metrics to increase 7T Tx RF antenna concept comparability and reproducibility, with the goal of a better technology transfer of antenna concepts across the MR community. Eight antenna concepts are evaluated based on power and SAR efficiency as well as mutual coupling and reliance on load changes using a rectangular phantom mimicking the average electromagnetic body properties. Based on the presented results, much information can be collected and deductions about each antenna's preferable ambits drawn. In conclusion, this work initiates a first standardized protocol for analyzing Tx RF antenna concepts.
