X-ray computer tomography system for imaging flat multilayer circuit board, has rotational axis laid parallel to main ray axis of electron rays of transmission target-x-ray tube, where electron rays produce x-rays

摘要

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. An independent claim is also included for an X-ray computer tomography method for imaging of a flat object.
