A method for generating result slice images with at least partially different slice thickness based on a tomosynthesis image data set of a breast includes generating average value slices and maximum value slices (MIP) based on the tomosynthesis image data set, frequency dividing the average value slices into low-pass filtered and high-pass filtered average value slices, high-pass filtering of maximum value slices to form high-pass filtered maximum value slices, mixing high-pass filtered maximum value slices and high-pass filtered average value slices to form mixed high-pass filtered maximum value slices, combining the low-pass filtered average value slices with the mixed high-pass filtered maximum value slices to form the result slice images, and applying a moving maximum value across a selected thickness of maximum value slices or across a selected thickness of mixed high-pass filtered maximum value slices.

A method is for making an X-ray recording of an examination region of an examination object with an X-ray system including an X-ray source arranged on an emitter displacement unit and an X-ray detector including a detection area, arranged on a detector displacement unit. The method includes selecting the examination region and portion-wise recording successive recording portions in relation to the examination region. The portion-wise recording includes moving the X-ray source and the X-ray detector, determining a strip-shaped detection region within the detection area, by expanding an extent of the X-ray recording compared with a further different X-ray recording, and acquiring and recording each respective successive recording portion, of the successive recording portions, using the determined detection region and the X-ray source. Finally, the method includes generating an assembled X-ray recording of the examination region from the successive recording portions recorded.

A method for controlling an X-ray projection imaging device includes applying preferences for a serial radiography image acquisition to the X-ray projection imaging device. The method further includes executing the serial radiography image acquisition with the X-ray projection imaging device; recording data frames at different times during the serial radiography image acquisition; applying a trigger signal to the X-ray projection imaging device during the serial radiography image acquisition; and generating a snapshot image from a subset of the data frames, wherein the subset is chosen from the data frames recorded based on the trigger signal. A related system, a related control unit and a related X-ray projection imaging system are also disclosed.
