DEVICE AND METHOD FOR AUTOMATIC X-RAY EXAMINATION OF A MOVING TEST OBJECT

摘要

A device (100) for automatic x-ray examination of a moving test object (120) comprising an x-ray arrangement (105) having an x-ray source (110) and an area detector (130), comprises a manipulation device (150) for moving the test object (120) relative to the x-ray arrangement (105) to a test position Y_P between the x-ray source (110) and the x-ray detector (130), wherein the test object (120) has a relative velocity v_B to the x-ray arrangement (105) when moving through the test position Y_P, wherein the following correlation is satisfied in respect of the relative velocity v_B: (formula 1) or if the spatial resolution required for the application is lower than the effective pixel size: (formula 2) comprising an image acquisition duration_tint, a relative velocity v_B and an effective pixel size or a target spatial resolution, which is based on the relationship between the source-detector distance of the x-ray source to the area detector and the source-test object distance from the x-ray source to the test object, a processing device (160) for capturing an x-ray image of the test object (120) moving at the relative velocity v_B at the test position (Y2) by means of the area detector (130) and an evaluation device (170) for automatic evaluation of the x-ray image of said test object (120) in respect of a material or quality feature by means of an image processing device.
