A tight fitting and wearable 15-Channel Head Cap Array using Twisted-Pair Elements was designed and characterized for potential use in a multimodal imaging system. The RF Array was characterized in terms of safety and SNR. The elements in the array (Twisted-Pair coil) show >40dB isolation for active detuning with no significant component heating under harsh RF conditions (ΔT<4°C). SNR evaluations revealed a 3x increase in peripheral SNR and retainment of SNR under parallel imaging conditions when compared to a commercial head array. An array of this caliber can be used for fMRI sleep studies and simultaneous TMS/EEG/fMRI.
