This study presents a novel receive radiofrequency coil that enhances the signal-to-noise-ratio (SNR) and field-of-view (FOV) in magnetic resonance images. The fabricated coil is loaded by a mixture of dielectric material (TiO2) and an elastomer offering stretchability and flexibility. The functionality of the coil compared to a typical surface coil was assessed using phantom imaging at 7T. The SNR (in dB), signal intensity, and uniformity are improved by 14.75%, 25%, and 87.76% by using a TiO2-loaded coil, respectively. This design method will be invaluable for uneven sample shapes and a very close place to a subject.
