A High-Performance Conformal Metamaterial for 1.5 T Wrist Magnetic Resonance Imaging.

Improving the signal-to-noise ratio (SNR) is crucial for enhancing image quality and diagnostic reliability in magnetic resonance imaging (MRI). However, traditional methods that rely on increasing the number of coil channels are approaching their physical and engineering optimization limits. In recent years, wireless,...
