Ellingson, W A; Vannier, M W

This report characterizes the current status of x-ray computed tomography (CT) as applied to the nondestructive evaluation of ceramic materials. The principal advantages of x-ray CT scanning are two. The first is the capability to produce high-contrast, geometrically accurate digital pictures (images) of slices through an object with a reasonably high spatial resolution. The second is that these slice images are not influenced to any significant degree by overlap or by structures outside of the plane of section (the tomographically imaged plane). Conventional radiography offers neither of these advantages. 34 refs., 42 figs., 4 tabs.
