Analysis of High-Speed CT Scanners for Non-Medical Applications

There are non-medical applications for CT (computerized tomographic) scanner technology which are feasible and potentially important. We have identified several applications related to the general problem of measuring cross-sectional density distributions in two-phase flowing mixtures and have analyzed a general class of CT scanner designs which suit these applications. Specifically, this paper reports the results of an analysis of CT scanners which (1) are appropriate for two-phase fluid density measurements, (2) are based upon stationary detector array scanner designs, (3) incorporate a rotating isotopic fan-beam source, (4) permit continuous scanning of the object, and (5) can achieve 10 millisecond scan times.
