We propose a method to remotely acquire MR images at 7 T with a preclinical imager using a bio-inspired surface coil, a parallel-plate waveguide and a non-selective metamaterial. Phantom images were acquired with and without a flexible metasurface inserted in cylindrical phantom filled with saline solution and a birdcage coil. Uniformity profiles were computed for all cases showing that the birdcage coil and metasurface profiles have a very good correspondance. An improvement was observed for the images obtained with the metasurface. This approach offers a convenient alternative to obtained high quality images.
