Abstract (en)
[origin: WO2014161903A1] 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 YP between the x-ray source (110) and the x-ray detector (130), wherein the test object (120) has a relative velocity vB to the x-ray arrangement (105) when moving through the test position YP, wherein the following correlation is satisfied in respect of the relative velocity vB: (formula 1) or if the spatial resolution required for the application is lower than the effective pixel size: (formula 2) comprising an image acquisition durationtint, a relative velocity vB 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 vB 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.
