Enhancement of Magnetic Resonance Imaging with Metasurfaces

Adv Mater. 2016 Mar 2;28(9):1832-8. doi: 10.1002/adma.201504270. Epub 2016 Jan 11.


It is revealed that the unique properties of ultrathin metasurface resonators can improve magnetic resonance imaging dramatically. A metasurface formed when an array of metallic wires is placed inside a scanner under the studied object and a substantial enhancement of the radio-frequency magnetic field is achieved by means of subwavelength manipulation with the metasurface, also allowing improved image resolution.

Keywords: magnetic resonance imaging; metamaterials; metasurfaces; near-fields; resonators.
