Synopsis

We present the first continuous 30-channel loop receive coil array combined with the 10-channel dipole parallel-transmit array for 7 Tesla body imaging. Array comprises a flexible anterior part with 6 dipoles and 18 loops, with 35cm longitudinal coverage along with a hard plastic posterior part containing 4 dipoles and 12 loops. Special features were added to help patient comfort and overcome cabling limitations. Simulations with computational human model show adequate B₁⁺ coverage in areas of interest such as the prostate. Phantom images were taken showing promising results. Further development will follow, and human imaging is planned in the near future.
