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
While tomographic methods of reconstructing three~dimensional x-ray images are becoming more common in the medical field, their application to industrial problems has only started. Some of the features that differentiate industrial tomography from medical tomography are
- x-ray energies may vary from< 10 keV to> 22 MeV
- radiation dose to the object is not a constraint
- inspection times (within economic constraints) are not as important
- the anomalies to be detected offer sharp, high contrast boundaries to the inspection system
- high spatial resolution rather than high contrast sensitivity is the primary design goal, and
- the number of views may be limited by other (mechanical) constraints.
This paper will describe the effort the Los Alamos Scientific Laboratory (LASL) is making to define the design parameters that affect the constraints listed above. A tomographic test bed in which various design features may be evaluated will be described. The computational facilities at LASL, which include a versatile modeling code that can simulate tomographic systems with various types of radiation, geometries, and detector types, will also be discussed.
