A wireless resonator layer for high-resolution TMJ MRI at 1.5 T

Motivation: Most imaging facilities lack specialized coils, resulting in suboptimal TMJ MRI scans using head receive array. Goal(s): Developing flexible, cost-effective and efficient accessories to enhance TMJ MRI image using existing facilities. Approach: Improve TMJ MRI scans by incorporating an inductive wireless resonator insert into a head array. evaluating its performance against the head array alone using phantom and in vivo imaging. Results: The SNR increases by 5.3-fold times at the TMJ's articular fossa area and remains 2.4-fold at a 4cm depth, using a wireless resonator insert and head array combination, compared to a phased array. Impact: Combining wireless RF resonators and phased arrays transformed MRI coils technology. It enhancing SNR in specific regions like the thyroid and carotid artery, allowing parallel imaging . This advancement ensures affordability, well-workflow, and the adaptability to various magnetic field strengths.
