ABSTRACT:
During tomosynthesis a plurality of x-ray images is acquired. The angular position of the x-ray tube is changed from x-ray image to x-ray image. Absorption in the imaged object (patient) and also in the patient table changes as a function of the angle. To compensate for this, backlight is applied while the x-ray images are being acquired. The intensity of the back light is selected as a function of the angle of the x-ray tube to the normal of the flat x-ray detector. Backlight can also be directed during reading, with only the areas already read in each instance being irradiated.
