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

Laminography is an imaging method that visualizes a plane of a three-dimensional object using multiple x-ray imaging [1,2]. A laminograph is produced by aligning features in the component radiographs for a particular “plane of focus”and averaging the radiographs to emphasize the features of interest. Due to the averaging process, relative strong features in another plane, while being reduced in intensity, may still be visible after the laminographic process and may cause incorrect human interpretations. A general artifact reduction scheme for laminography is presented in this paper.
