New Technology Could Improve MRI Quality

Feb 04, 2016

An international group of researchers has developed a technology that it claims can improve the quality of magnetic resonance images while simultaneously reducing scan times by more than 50%.

According to a study published in the journal Applied Materials, the gains are achieved through the use of metamaterials, a type of engineered surface capable of manipulating electromagnetic waves. The technique works by increasing the signal-to-noise ratio in the scanned area.

“Our metamaterial can be embedded directly into the patient table of any commercially available MRI scanner,” said Alexey Slobozhanyuk, an author of the study, in a news release. “However, in the future we see even more potential in the concept of special smart clothing for MRI scanning.”

By suppressing the electric field, the metamaterial was also shown to eliminate most tissue heating, which can compromise the safety of MRI procedures.
