Non-destructive investigations of high-speed processes that cannot optically be observed demand other imaging techniques than high-speed video or photography. One approach would be imaging methods based on X-radiation. To avoid motion blur flash X-ray technology is well known in this context. Furthermore high frame rates that allow following the velocities of these processes are desired. For this a system of sources and detectors has been developed at the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, and referred to as X-ray Cinematography. It is about a novel radiological time resolving imaging system using high-speed photography equipment. Information on the dynamics of high-speed processes is obtained without influencing the process itself. The spatial resolution of the system is 1280 × 1024 pixels with a signal dynamic range better than X-ray film at best. Up to eight pictures at a maximum frame rate of 100,000 fps are possible. Possible applications lie in the field of automotive crash, safety devices and material failure behaviour.
