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
Many applications of ultrasonic testing (UT) are made difficult by the complex geometrical shape of the part to be inspected. A simple ray-trace analysis of the geometry may suffice to determine transducer positions and beam angles to provide adequate coverage of the region to be interrogated. In addition, however, the analyst must have estimates of backscattered amplitudes to determine if flaw signals are measurable. Thus, a combination of complex-geometry ray tracing with calculations of flaw-scattering amplitudes is required for the design and optimization of UT procedures.
