Abstract
- International audience; We propose the dual-tuned volume coil for magnetic resonance imaging at two nuclei. This coil is based on the combination of two independent metasurfaces that can be used simultaneously for fluorine and hydrogen 19 F / 1 H imaging at 7 Tesla for small animals. Each metasurface is made of non-magnetic metallic rods and structural capacities of etched metal strips. The geometry is chosen so that two modes supported by the two metasurfaces resonate at the required frequencies 282.6/300.1 MHz. The two metasurfaces can be tuned independently by mechanically adjusting the length of the two sets of wires. We have numerically studied the concept of the proposed dual-tuned coil.
