Latest Radiography Stories
It pays to persevere. No one knows this better than Will Zhang. For more than a decade, the astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md., experimented with a new technique for efficiently manufacturing super-thin, low-cost curved telescope mirror segments to collect and focus ever-elusive, high-energy X-ray photons. The fruits of that labor -- a total of 9,000 individual mirror segments -- are now assembled into telescope optics and installed inside NASA's...
Radiation no longer required to detect common congenital birth defect Developmental dislocation (dysplasia) of the hip (DDH) is a common congenital condition in which a child's upper thighbone is dislocated from the hip socket. The condition can be present at birth or develop during a child's first year of life. Plain radiography (X-rays) has long been the gold standard screening modality for this condition in 6-month-old children, despite concerns over exposing very young children to...
