Ultra high speed electron beam tomography for flow measurement and small animal imaging

We introduce ultra high speed electron beam tomography as a new imaging tool for multiphase flow measurement and small animal imaging. The technique is based on imaging with X-rays produced by a rapidly scanned electron beam instead of a mechanically rotating source-detector compound. The scanner device ROFEX was developed manufactured and commissioned recently at FZD and allows scanning of objects with up to 7.000 frames per second speed and 1 mm spatial resolution. Application examples from multiphase flow measurement and small animal imaging are presented. Multiphase flow imaging mainly benefits from fast scanning which is impossible with any other imaging technology at this temporal and spatial resolution. Small animal imaging with ultra fast electron beam CT, however, is still in its beginning. Here higher spatial resolution and 3D imaging is needed.
