Imaging method enables 3X better spatial resolution, 7X reduction in amount of noise; reduced exposure to radiation from medical X-ray

"measures individual photons on a time-resolved and spatially-resolved basis. This makes it possible to separate signal photons from noise photons... detects each individual photon emitted from each neutron... enables real-time image reconstruction... takes us away from the traditional model of exposure time and we measure only those events which have occurred... ghost images also eliminated"

"compensates for the drift and deformation... achieved a resolution below 10 nanometers... upgraded facility will generate high-energy X-ray beams that are up to 500 times brighter than those currently possible, and further advances in X-ray optics will enable even narrower beams with higher resolution"

World record broken for thinnest X-ray detector ever created
"SnS nanosheets possess high photon absorption coefficients, allowing them to be used in making ultrathin soft X-ray detectors with high sensitivity and a rapid response time... less than 10 nanometres thick... scan something and get an image almost instantaneously.... see cells as they interact. You’re not just producing a static image, you could see proteins and cells evolving and moving using X-rays"
