Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

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 backscatter tomography (XBT), based on the detection of Compton scattering, has been applied to a variety of NDE problems with varying success. Its strength is its applicability with access to only one side of an object. The method is limited, however, to the detection of features near the surface of relatively light materials. When used to inspect structured or dense materials, XBT is plagued by superposition artifacts and limited by attenuation and noise. We often investigate the feasibility of using XBT for particular applications by trial and error, acquiring data from material specimens using varying inspection parameters.
