Roentgencomputertomographiesystem zur Darstellung flaechiger Objekte

DE 102007045797 A1 UPAB: 20090509 NOVELTY - The system has a rotary table (3) arranged in an optical path of a transmission target-x-ray tube (1). The table is provided for holding an object i.e. circuit board, and for rotating the object around a rotational axis (R). A detector (4) and an image reconstruction unit (5) i.e. personal computer, are arranged in the optical path of the tube according to the rotational axis, where the image reconstruction unit is provided downstream to the detector. The rotational axis is laid parallel to a main ray axis (E) of electron rays of the tube, where the electron rays produce x-rays. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an X-ray computer tomography method for imaging of a flat object. USE - X-ray computer tomography system for use in quality assurance or material testing for imaging of a flat object i.e. equipped or non-equipped multilayer circuit board (all claimed), where the circuit board is utilized for highly integrated electronic circuits. ADVANTAGE - The system is designed such that different regions of large flat circuit boards including intrinsic details in all spatial directions are imaged in a simple manner with high resolution and reduced region-of-interest (ROI) artifacts
