Metasurface-Based Technology Enables Safe MRIs for People with Implants

An international research team has developed a device capable of improving the performance of magnetic resonance imaging (MRI) units. The technology is based on local redistribution of a magnetic field with the help of a metasurface made of metal resonators. It was proven experimentally that the metasurface is capable of reducing the power required to produce high-quality images using an MRI unit. The use of MRI units of lower intensity makes it possible to make MRI diagnostics safe for people with medical implants. The results of this research were published in the Journal of Magnetic Resonance. 1
