Abstract
A half-open seven-element volume quadrature TEM coil has been developed by utilizing two orthogonal resonant modes made degenerate in frequency and operated 90 degrees out of phase. The coil combines the features of a volume and surface devices, providing large B1 homogeneous region as well as improved efficiency, patient comfort and accessibility. Additionally, it self-compensates the RF penetration artifact, which is generally observed for linear coils at high frequencies. The design details as well as the results of the phantom and volunteer studies are provided.
