This Collection invites original research articles on phase contrast imaging, looking at the latest technological developments and the use of this technique in original applications. Phase contrast ...

X-ray phase contrast imaging harnesses the phase shift that X-rays undergo when traversing a specimen, offering contrast mechanisms beyond simple absorption. By detecting refraction and ...

Researchers report a nonvolatile phase-programmable spintronic terahertz emitter that uses femtosecond laser pulses to switch THz phase states and magnetic fields to reset them. The device enables ...

An imaging process that today is used mainly in research labs could potentially detect early-stage lung disease if developed for use in hospitals and clinics, a new research study shows. Researchers ...
