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
To obtain the high performances requested by the safety authorities for ultrasonic inspections, in term of sizing, characterization and on-line monitoring, it is needed to vary the refracted angles, focusing depths and the size of the ultrasonic beams rapidly and over a wide range. This is not possible with conventional techniques which allow only fixed focusing. The F.A.U.S.T. (Focusing Adaptive UltraSonic Tomography) system, which is described in this paper, is an open and powerful tool designed to overcome the difficult problems in flaw assessment and monitoring.
