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
Ultrasonic (UT) inspection can be used to detect a wide variety of subsurface discontinuities, such as inclusions, cracks and voids, as well as associated reactive or diffusion zones. In comparison with Eddy-Current inspection, much less work has been done on the determination of the Probability of Detection POD of UT inspections. This is because, unlike Eddy-Current inspection, it is very difficult to produce synthetic sub-surface flaws that adequately represent the acoustic properties of the naturally-occurring flaws (see Burkel et al., 1996). Here traditional methods for POD determination are difficult to apply.
