摘要: Ultrafast X-ray computed tomography (CT) is an imaging technique with high potential for the investigation of hydrodynamics in multiphase flows. For correct determination phase distribution such flows, a accuracy reconstructed image data essential. In CT, radiation scatter may cause disturbing artefacts. As scattering not considered standard reconstruction algorithms, additional methods are necessary to detector readings or prevent detection scattered photons. this paper, we present analysis background ultrafast CT system ROFEX at Helmholtz-Zentrum Dresden-Rossendorf and propose correction based on collimation deterministic simulation first-order scattering.
