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
One of the most important characteristics of any imaging system is spatial resolution. This report describes a custom linear array Xenon ionization chamber detector developed by GE for sub-millimeter spatial resolution applications. The suitability of such a detector for high resolution digital imaging of turbine blades in both Digital Fluoroscopy and Computed Tomography modes is demonstrated.
