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
A direct solution of the ultrasonic inverse scattering problem, known by the acronym POFFIS, which stands for Physical Optics Far Field lnverse Scattering, has been developed. This technique has been used to reconstruct the shape and size of both simulated and real void flaws in materials.
