In 1999 SEIFERT and Fraunhofer Gesellschaft started to cooperate in the field of three-dimensional computed tomograhy (3D CT).

As an integral NDT method it is particularly suited to detect, characterise and measure voluminous defects in materials and components.

During a 3D CT measurement routine, an object is being rotated in the X-ray cone beam through 360° whereby a flat panel detector takes an X-ray exposure at each angle position of the test object. By using a mathematical reconstruction algorithm, a 3D distribution of the X-ray attenuation coefficient is reconstructed in the object volume. The 3D visualisation of the test volume is intended to show details and materials of interest before it is displayed on the PC screen via videos that are MPEG and AVI compatible.
