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
With increased demand for higher resolution ultrasonic evaluation, computer-based systems or workstations now become essential. In this paper a typical high resolution ultrasonic inspection system is presented. HIRUSIS, an mnemonic for HIgh Resolution UltraSonic Inspection System, is developed primarily for the purpose of high performance hidden flaw characterization and feature-based classification. The basic system comprises a PC (Personal Computer), a Pulser/Receiver and a Digital Oscilloscope as shown in Fig. 1. The system is further supported by several customized software packages for remote control of the devices, signal acquisition and presentation, one-dimensional and multi-dimensional signal processing, pattern recognition and B-scan image reconstruction. More image processing softwares will be added in the near future
