Keywords: New Devices, RF Arrays & Systems, Invisible Dielectric pad, Silicon Carbide, SNR enhancementWe propose a stretchable, flexible, and MRI invisible dielectric pad to enhance the quality of acquired MR images. A silicon-based elastomer is mixed with Silicon Carbide (SiC) to develop this proposed dielectric pad. Preclinical in-vivo imaging of a mouse head was conducted at 9.4T to validate the performance of the dielectric pad. 2.54% (in dB) increase in the central SNR of the brain was observed after using the dielectric pad and peripheral brain locations have shown improved contrast. The flexible and stretchable dielectric pad could be used as a substitute for conventional dielectric pads, especially in irregular sample shapes.
