Synopsis

Keywords: RF Arrays & Systems, Parallel Imaging

Motivation: Dual-tuned cable traps, instead of two separate single-tuned ones in series, are preferred in multi-nuclear MRI and MRS.

Goal(s): We introduce a frequency-independent dual-tuned cable trap. For proton nuclear, standard solenoid cable trap was employed. For X-nuclear, an additional solenoid resonator was employed to block the common-mode signal.

Approach: The dual-tuned cable trap was analyzed in electromagnetic simulation, fabricated and its performance is evaluated by bench test.

Results: The dual-tuned trap exhibits exceptional common-mode current suppression abilities at both frequencies. And two frequencies of dual-tuned trap can be adjusted independently without mutual interference.

Impact: This novel dual-tuned cable trap fills an important gap in dual-tuned MRI hardware for multi-nuclear magnetic resonance studies, potentially enable next-generation dual-tuned coils.
