Metamaterial MRI Antenna Delivers Sharper Eye and Brain Imaging on Existing Scanners
Researchers at the Max Delbrück Center and Rostock University Medical Center unveiled a metamaterial-based MRI antenna that strengthens signals from deep tissues, enabling higher-resolution images of the eye and occipital brain regions and potentially shorter scan times without new equipment. Tested at 7.0 Tesla on volunteers, the compact antenna can be adapted to different body parts, may help reduce heating near implants, and could enhance MRI-guided therapies; larger clinical studies are planned and the approach targets broader organ imaging in the future.
