Industrial X-Ray Tomograph / Computertomograph, 420 kV

At the Institute for Multiphase Processes of the Leibniz University of Hannover X-ray tomograph (computer tomograph, CT) is used as a non-intrusive measuring system for complex multiphase flows. Since January 2003 the institute has been operated its own industrial X-ray tomograph. Identical x-ray tomographs are used in industry for example for non-destructive testing of materials and components as well as for measuring geometries for reverse engineering. Such equipment is used amongst others in the automotive and aircraft industries.
