Elekta AB (publ) said the U.S. Food and Drug Administration approved the use of Elekta Unity in diffusion-weighted imaging.

The FDA clearance allows diffusion-weighted images derived using Elekta Unity to be interpreted by trained physicians.

Diffusion-weighted imaging is a technique that uses the motion of water molecules to create contrast in magnetic resonance images.

The Stockholm-based company's Elekta Unity technology allows doctors to better target cancers and allows for personalized radiation therapy regimens.
