Ultra-high field strengths of 7 T and above promise a high SNR which is useful especially when trying to image nuclei with only a small incidence such as 19F, but inhomogeneities due to the short wavelength cause severe problems. In this work we present a flexible 8ch Tx/Rx coil for human abdominal imaging of 1H and 19F at 7 Tesla allowing the use of the same B1 shim for 1H and 19F. The array and the 8-ch transmit system were successfully tested ex vivo for both 1H and 19F.
