Abstract

One or more example embodiments relates to an extra-focal beam aperture device for an X-ray emitter and to the X-ray emitter. The extra-focal beam aperture device according to one or more example embodiments for an X-ray emitter has a planar beam-shaping element including an X-ray opaque material, the planar beam-shaping element being configured to form a useful X-ray beam and an X-ray measuring beam separate from the useful X-ray beam, from an X-ray beam bundle incident upon the extra-focal beam aperture device, the planar beam-shaping element including two side faces opposite each other, a radial lateral surface between the two side faces, a cross-section through the radial lateral surface having an approximately trapezoid shape, and at least one cut-out for shaping the X-ray measuring beam, the at least one cut-out having a tapering cross-section.
