A process for creating a dual-energy X-ray image as well as corresponding X-ray system, computer program and computer-readable media

A process for the preparation of dual-energy X-ray image data of a predetermined volume portion of an inspection object (12) having an X-ray system (30), the method comprising the steps of: Creating low-energy X-ray image data of the bulk portion, Creating high-energy X-ray image data of the bulk portion, Subtract the low energy X-ray image data from the high-energy X-ray image data to create the dual energy X-ray image data characterized, that when creating the dual energy Rontgenbilddaten a Rontgenfilter used is that zumindest 90 Gewichtprozent is made of titanium, that the same X-ray filter is used to create the high-energy X-ray image data and to create the low-energy X-ray image data, and that the X-ray filter having a thickness of 0.5 mm to 1.2 mm,
