A method for controlling an FFS X-ray system comprises: simulating a beam geometry of the X-ray beam at a specified FFS deflection onto the detector during recording of a projection image; determining whether cross-radiation is present in a region around the detector by the simulated beam geometry of the X-ray beam; generating FFS control data for the recording of the projection image, wherein the FFS control data either (i) causes FFS deflection that is reduced relative to the specified FFS deflection for the recording of the projection image in the event of the cross-radiation being present for the recording of the projection image or (ii) causes the specified FFS deflection otherwise; repeating the simulating, the determining and the generating FFS control data for at least one further recording of a projection image; and generating a control data set including the FFS control data, for controlling an FFS X-ray system.

A method for positioning a body region of a patient for a radiography acquisition by a radiography system includes providing an examination requirement for the body region, pre-positioning the body region in the radiography system for the radiography acquisition, pre-positioning an acquisition unit of the radiography system for the radiography acquisition, producing a three-dimensional positioning acquisition of the body region using a 3D camera system, and producing a preview image from the three-dimensional positioning acquisition. A patient model is generated from the three-dimensional positioning acquisition and the preview image is produced from the patient model, and the preview image depicts a representation as if made using the acquisition unit of the radiography system. The method further includes outputting at least one of the preview image and positioning information based on the preview image. Another embodiment may use an apparatus and computer readable medium to execute the method above.

A first x-ray image is acquired at a predetermined position of a focal point and with a first orientation of an x-ray tube of an x-ray device. Subsequently, the x-ray tube is adjusted by rotating about a predetermined angle and by positioning, wherein the focal point is situated in the predetermined position prior to the adjustment and after the adjustment. After the adjustment, the x-ray tube is situated in a second orientation. Subsequently, a second x-ray image is acquired at the predetermined position and with the second orientation.
