Imagine looking at the inner structure of pretty much anything – and getting ultrahigh-quality, high-resolution images that show it changing over time. Researchers at the University of Nottingham in the UK are doing just that with a three-dimensional x-ray micro-CT system. Sacha Mooney from the university’s division of agricultural and environmental sciences previously had to borrow time on hospital scanners to look at soil structure. By taking an interdisciplinary approach and pooling resources, the university was able to purchase a Nanotom from phoenix x-ray, based in Germany, a division...Read full article

    image quality
    A measure of the closeness with which an optical image is capable of resembling the original object. The factors that affect image quality are lens aberrations, diffraction, dirt and stray light within the system, and atmospheric turbulence and haze outside it. If the image is recorded photographically, it can become further degraded by image motion during exposure and by light diffusion in the emulsion. At one time image quality was expressed by its resolving power, but today a more meaningful...
