Abdominal imaging at 7 T is challenging due to reduced RF penetration at 298 MHz. Conventional high-field surface coil arrays with stripline elements deposit high SAR levels and suffer from inhomogeneous B1-field distribution. We present results of a prototype coil array consisting of so-called radiative antennas. These elements emit power to the region of interest more efficiently. Simulations and volunteer measurements show reduced SAR levels and increased image homogeneity.
