New metamaterial-enhanced MRI technique tested on humans

Scientists from the Netherlands and Russia have designed and tested a new metasurface-based technology for enhancing the local sensitivity of MRI scanners on humans for the first time. The metasurface consists of thin resonant strips arranged periodically. Placed under a patient's head, it provided much higher signals from the local brain region. The results published in Scientific Reports, show that the use of metasurfaces can potentially reduce image acquisition time, thus improving comfort for patients, or acquire higher resolution images for better disease diagnosis.

X-ray microscope optics resolve 50-nm features while eliminating chromatic aberrations

X-ray microscopes are commonly used in combination with full-field imaging techniques in spectromicroscopy applications, where they allow the chemical structures of materials to be analyzed and visualized simultaneously. However, the performance of these microscopes is often affected by problems with chromatic aberrations— optical effects that limit the resolution or degree of fineness to which images of the material structures can be acquired—and previous solutions to the problem have often proved difficult to manufacture and implement. A collaborative team led by researchers from Osaka University has therefore developed an optical system for use in full-field X-ray microscopes that offers a more practical way to overcome the chromatic aberration problem.
