Abstract：
Temporomandibular Joint Magnetic Resonance Imaging (TMJ MRI) is crucial for diagnosing temporomandibular disorders (TMDs). This study advances the use of inductively coupled wireless coils to enhance imaging quality in TMJ MRI. After investigating multiple wireless resonator configurations, including a 1-loop design with a loop diameter of 9 cm, a 2-loop design with each loop having a diameter of 7 cm, and a 3-loop design with each loop having a diameter of 5 cm, our findings indicate that the 3-loop configuration achieves the optimal signal-to-noise ratio (SNR), surpassing other wireless arrays. Bilateral deployment of wireless coils further amplifies SNR, enabling superior visualization of TMJ structures, particularly with the 3-loop design. This cost-effective and comfortable solution, featuring a detunable design, eliminates the need for system parameter adjustments. The study indicates broad adaptability across MRI platforms, enhancing TMJ imaging for routine clinical diagnostics of TMDs.
摘要：
颞下颌关节磁共振成像（TMJMRI）对于诊断颞下颌关节紊乱病（TMD）至关重要。这项研究提出了使用感应耦合无线线圈来提高TMJMRI的成像质量。在调查了多个无线谐振器配置后，包括1环设计，环直径为9厘米，2环设计，每个环的直径为7厘米，和3环设计，每个环的直径为5厘米，我们的发现表明，3环路配置达到最佳信噪比(SNR)，超越其他无线阵列。无线线圈的双边部署进一步放大了信噪比，实现TMJ结构的卓越可视化，特别是3回路设计。这种具有成本效益和舒适的解决方案，具有可调谐设计，消除了对系统参数调整的需要。研究表明，MRI平台具有广泛的适应性，增强TMJ成像用于TMD的常规临床诊断。
