Motivation: Low-field MRI has garnered significant attention in recent years due to its unique advantages in safety, cost-effectiveness and accessibility. However, lower field strength comes with an inherently lower SNR as its primary limitation.

Goals: In this work, we introduce a novel volume RF coil design using coupled stack-up resonators to mitigate this challenge.

Approach: To demonstrate the proposed design, we take 0.5T as an example field strength and designed a prototype coupled stack-up volume coil operating in the 20MHz range.

Results: Compared to the birdcage coil, the proposed design significantly improves RF field efficiency and homogeneity, ultimately enhancing the performance of low-field MRI.

Impact: The proposed stack-up volume coil outperforms the standard birdcage coil in B1 efficiency and field homogeneity at low fields, ultimately improving the performance of low-field MRI and advancing its applications.

动机：近年来，低场磁共振成像因其在安全性、成本效益和可及性方面的独特优势而备受关注。然而，低场强的主要局限是信噪比较低：在这项工作中，我们介绍了一种使用耦合叠加谐振器的新型体积射频线圈设计，以缓解这一挑战：为了演示所提出的设计，我们以 0.5T 为例，设计了一个耦合叠加体积线圈原型，工作频率为 20MHz：结果：与鸟笼线圈相比，拟议的设计显著提高了射频场效率和均匀性，最终提升了低场磁共振成像的性能：建议的叠加式体积线圈在低场的 B1 效率和场均匀性方面优于标准鸟笼线圈，最终提高了低场磁共振成像的性能，并推动了其应用。
