Metamaterial-Enhanced Imaging Technique Could Reduce Acquisition Time

Facebook Twitter LinkedIn Email Comments
ST. PETERSBURG, Russia and LEIDEN, Netherlands, June 20, 2017 — A hybrid metasurface structure, composed of a 2D metamaterial surface and a high permittivity dielectric substrate, has been shown to enhance the performance of an ultra-high field MRI scanner. The ultrathin structure could potentially be used to reduce image acquisition time or, alternatively, to facilitate higher resolution images. Metasurface structure and application.

Use of large metamaterial structures would...Read full article
