Motivation: In 3T MRI, achieving optimal B1 field efficiency and reducing specific absorption rate (SAR) are essential for enhancing image quality and patient safety.
Goal(s): To develop a multimodal concentric surface coil that improves B1 field efficiency and reduces SAR compared to conventional surface coils.
Approach: The novel coil design incorporates five electromagnetically coupled concentric resonators to form a multimodal resonator. Performance was evaluated through simulations and bench tests.
Results: Both simulations and bench tests demonstrate that the concentric coil achieves superior B1 efficiency and lower SAR, underscoring its potential to improve image quality and safety in in vivo MRI applications.
Impact: The proposed multimodal concentric coil demonstrates superior B1 field efficiency and reduced SAR compared to conventional surface coils. These improvements can significantly enhance image quality and patient safety in 3T MRI, paving the way for better clinical outcomes.
