Metamaterial head coil for Ultra High Field MRI

The EU-funded M-ONE project aims to demonstrate a breakthrough innovative MRI coil for ultra-high field (UHF) MRI brain imaging at 7 Tesla (7T), resulting in homogeneous images of better quality. UHF allows a better deciphering of brain mechanisms and a better diagnostic of brain diseases. However, some radio frequency field inhomogeneities that appear at 7T result in dark areas on the brain images, making diagnosis in specific brain regions inconclusive or even impossible. A previous project, M-CUBE, established two metamaterial-based technologies to obtain homogeneous brain images. The key objective of the current project is to develop a 7T metamaterial head coil with the best homogeneity and higher signal-to-noise ratio than the standard 7T head coils on the market.
