Metamaterials boost sensitivity of MRI machines

A group of researchers from Russia, Australia and the Netherlands has developed a technology that can reduce magnetic resonance imaging (MRI) scanning times by more than 50 percent, allowing hospitals to drastically increase the number of scans without changing equipment. This extraordinary leap in efficiency is achieved by placing a layer of metamaterials on the bed of the scanner, which improves the signal-to-noise ratio. The details of this experimental research are available in the current i
