Hairpin Radio Frequency Coil Array with High Inter-channel isolation for 7T Magnetic Resonance Imaging.

The quest for ultimate intrinsic signal-to-noise ratio (uiSNR) and higher spatial resolution at ultra-high field for parallel magnetic resonance imaging is contingent to the integrity of the magnetic flux density map from individual channel. RF coils design using hair-pin matching technique is introduced to provide intrinsic decoupling performance within array of elements. This technique does not require any additional circuit between coil elements or large value of lumped inductance to provide simultaneous decoupling between adjacent and non-adjacent coils. The simulated results including decoupling performance, field distribution, and SNR are provided to validate the feasibility of the proposed design.
