Physicists from Russia and the Netherlands say about the successful test on volunteers a new type of MRI scanner, which uses a special metamaterial on the basis of copper, making the image clearer, according to a paper published in the journal Scientific Reports.

«In order to distinguish a useful signal against the background of random noise, doctors repeat the scan many times. But netpowersoft this is not necessary. If now examined, conventionally, takes twenty minutes in the future doctors will be enough for ten. If today, the clinic serves ten patients a day, with this development will take twenty», — says Alexey Slobozhanyuk, a physicist from University ITMO in Saint-Petersburg.

As the scientists explain, magnetic resonance imaging is based on the effect of the so-called nuclear magnetic resonance. During a session of imaging the brain or other human organs are exposed to the radio waves in the presence of a powerful permanent magnet, causing the nuclei of hydrogen and other atoms in the body tissues start vibrating, radiating or absorbing waves at a certain frequency.

Watching these waves, scientists can calculate the position of that atom in tissue temperature or other properties of the organ under investigation, including how microwave radiation affects cells. To work MRI uses powerful magnets on the basis of superconductors, which limits their use and makes their operation quite expensive.

A year ago, Slobozhanyuk and his colleagues from ITMO and the University of Leiden (Netherlands) was able to expedite the work of the MRI scanner, providing a metamaterial from pieces of copper, which makes the resulting image more contrast. This allows physicians to obtain a sharp image in less number of scans to increase the resolution and get them for much less time.

Flexible plates made of this material, as they say scientists need to be placed next to the superconducting magnets of MRI scanners at the point where the body of the patient during the examination. This will reduce the noise and reduce the size of individual three-dimensional «pixels» on the image that gets scanner.

The work of these metamaterials and scanners, the researchers tested the volunteer who agreed to undergo several treatments of brain scan with and without the use of the material. These experiments ended successfully – scientists were able to obtain clear pictures of the brain of the participant experiences three-dimensional image of his face using the scanner.

Russian and foreign physicists are going to continue studies in Leiden and St. Petersburg. They hope to turn the applied physics laboratory at ITMO University in the center for advanced development in this area, to buy modern equipment and to attract young professionals to create prototypes and implement them into clinical practice. To do this, the staff of the laboratory of applied physics, Andrew Webb sent an application for the grant of the RSF.
