A Magnetic Resonance Imaging Surface Coil Transceiver Employing a Metasurface for 1.5T Applications

A capacitive impedance metasurface combined with a transceiver coil to improve the radio frequency magnetic field for 1.5T magnetic resonance imaging applications is presented. The novel transceiver provides localized enhancement in magnetic flux density when compared to a transceiver coil alone by...
