Tomography: an overview of the AECL program
Abstract
Tomography represents a nonintrusive nondestructive testing technique which makes it possible to generate quantitative cross-sectional density maps of objects. A series of such tomographs provides a basis for constructing a three-dimensional (3-D) image of the object, be it solid or liquid. The principles of the involved operations have already been discussed by Randon (1917). However, the availability of low cost computing power has now made a widespread use of tomography practical. The present paper provides a review of a program which has the objective to develop tomography as an industrial tool for the benefit of Canadian industry including the nuclear industry. At present, particular attention is given to photon transmission tomography. Test facilities and design tools are considered along with the potential and limitation of industrial tomography.
