Piecing Coils Together: A Wearable Modular Head Coil Design

Puntos clave

The head coil array provides up to 25% higher sensitivity at the periphery compared to a commercial model.
Results indicate a 30% lower central sensitivity in a head phantom when compared with existing devices.
Constructed using shielded-loop resonators, the design avoids complex geometric decoupling challenges.
This modular approach allows for wearable, flexible configurations without the need for decoupling electronics.

Resumen

Motivation: RF coil arrays with many channels offer higher SNR when arranged closely to the anatomy. Production of high-density RF coil arrays is challenging due to cabling and decoupling problems. Goal(s): To create a modular design for array elements with reduced complexity, and test it in a 64-channel head coil setup. Approach: 64 shielded-loop-resonators (SLRs) were constructed and arranged on elastic head cap without geometric decoupling; bench test and MRI measurements were performed. Results: The head coil array offered up to 25% higher SNR at the periphery compared to commercial 64-channel coil, while up to 30 % lower central SNR in a head phantom. Impact: The concept of a wearable and flexible modular coil arrays is demonstrated, where the elements are positioned together without any geometric adjustment or decoupling electronics. The modular design simplifies coil array construction and offers more flexibility in anatomical coverage.
