Paper Abstract

In industrial diagnostics, direct imaging of dynamic variables is often as important as frame sequences of configuration and composition static distributions. There have been only a few studies presented on the application of transverse axial tomography techniques to the direct development of dynamic images. In this paper, a new nonintrusive transaxial tomography method for the measurement of three-dimensional fluid velocity profiles is suggested. The technique employs the sensing of the transit time of a physical signature which is carried by the fluid. This signature is detected at locations marginal to the fluid flow region and thus usually is represented by a configuration convolution over a region of the flow. Since time of fluid transit is the variable which is imaged, the technique is labelled Transit Time Transaxial Tomography. To aid in development of the idea of the method, it is progressively detailed for the special case of a radioactive nucleus decay signature and a fluid flow meter concept which could be applied to a nuclear power plant. Generalization of the ideas are then presented in the conclusion of the work.
