Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
X-ray computed tomography (CT) uses penetrating radiation measurements from many angles about an object to reconstruct cross sectional images of the object interior [1–2]. The images are two dimensional maps of the X-ray linear attenuation coefficient for small volume elements in the object defined by the effective X-ray beam size. The CT images provide quantitative measures of component feature dimensions and density as related to the linear X-ray attenuation of the material under study.
