  • the invention relates to a method and a device for examining objects by means of radiation.
  • X-ray examinations have traditionally been their main application in the field of medical technology. Recent developments aim to use more and more X-ray technology for the examination of workpieces and components. The improvements in X-ray technology allow an ever more efficient workflow in component testing. A shortening of the time intervals for the examination of individual components or workpieces requires appropriate adjustments of the overall process.
  • the examination result is not necessarily examined on the spot by monitoring personnel and, if necessary, inspected more closely.
  • the result of the examination may be at a different stage in the process. For example, such a constellation is given when performing a series of examinations that the workpiece has to pass in total to be suitable for use.
  • the readout of a component would make sense only after all investigations have been carried out. That is to say, in particular, that at this time the test results for a possible assessment must be available at a location remote from the examination site in order to be used there for a decision.
