In a method to create dual energy x-ray image data of a predetermined volume segment of an examination subject with an x-ray system, a low-energy x-ray image data of the volume segment is created, a high-energy x-ray image data of the volume segment is created, the low-energy x-ray image data is subtracted from the high-energy x-ray image data to create the dual energy x-ray image data. An x-ray filter that consists essentially of titanium is used in the creation of the dual energy x-ray image data.

Method and x-ray system to create a dual energy x-ray image

In an x-ray diagnostic apparatus for tomosynthesis or laminographic imaging using a patient positioning table, an x-ray source which emits an x-ray beam on one side of the patient positioning table, an x-ray detector arranged on the other side of the patient positioning table for the capture of the x-ray beam and for producing digital images, a device for movement of the x-ray source, a device for shifting of the x-ray detector and a device for superimposing the digital images so that only the details lying in a specific longitudinal slice for an examination subject are sharply imaged, the x-ray detector is rotated relative to the movement direction at an angle.
