A new generation of sharp-eyed mechanical inspectors can spot microscopic cracks that are just one-fiftieth the diameter of a hair. These high-resolution industrial scanners, called micro CTs, may deliver life-saving early warnings, finding flaws in turbine blades before they are mounted on jets, or in helmets or pieces of body armor before they are worn by soldiers.

Micro CTs, like the more familiar CAT and CT machines used in health care, take X-rays from many angles that are then combined by computer to create detailed, three-dimensional images.
