Detunable Wireless Litzcage Coil for Human Head MRI at 1.5T

Motivation: Detuning wireless volume coils is challenging due to their complex structure, multiple resonant modes and multiple detuning circuits. Goal(s): Developing an efficient method to geometrically decouple from the body coilApproach: Designing an inductive birdcage coil featuring a figure-of-eight conductor pattern within the rungs, conducting volunteer and phantom image for compare its performance with the body coil and a receive array. Results: The wireless Litzcage coil offers ~3.9 times higher SNR than the body coil. A 10% boost in the central area, a 21% reduction at the surface, and similar head image quality compared to a commercial 12-channel Head coil. Impact: Applies to 0.55T, 3.0T, and 7T MRI systems, and expands to extremity, breast and body imaging. Simplifies coil design, improves detuning, and lowers costs. Lightweight and user-friendly, enabling MRI-guided therapy and streamlined clinical processes.
