    Abstract: A method to show a predetermined volume segment of an examination subject by means of a tomosynthesis apparatus, and a correspondingly designed tomosynthesis apparatus, operate as follows. A radioscopy test is implemented in which x-rays with a defined radiation dose are generated by an x-ray source, the x-rays traversing the predetermined volume segment and strike a detector, and an intensity of the x-rays striking the detector is determined. A first radiation dose of x-rays is calculated to create a two-dimensional exposure depending on the determined radiation dose and the intensity. A second radiation doses of x-rays is calculated to implement a tomosynthesis depending on the determined radiation dose and the intensity. A tomosynthesis of the predetermined volume segment is implemented with x-rays that traverse the predetermined volume segment and strike the detector, the x-rays being generated by an x-ray source with the second radiation doses.

    Abstract: In a method and system for monitoring the power state of an x-ray emitter and/or an x-ray detector, the x-ray emitter is operated according to a set of test parameters, so as to emit x-rays that strike at least a portion of the detector region of the x-ray detector. At least one value characterizing the operation of the x-ray emitter and/or the x-ray detector is determined, and this detected parameter is compared with a comparable reference parameter value. The power state of the x-ray emitter and/or the x-ray detector is determined based on deviation of the detected parameter from the reference parameter.

    Abstract: A mammography system has an x-ray source, a detector and a compression plate arranged in the beam path between the source and the detector. The x-ray source, the detector and the compression plate are mounted on a vertical column such that they respectively pivot around separate pivot axes. The three pivot axes are spaced apart from one another and oriented substantially parallel to one another and substantially perpendicular to a surface normal of the detector. The x-ray source and the compression plate are held on the vertical column such that they can be displaced in a plane oriented approximately vertical to their pivot axes. The mammography system is operable to obtain two sets of tomosynthesis data respectively with different tube-to-detector distances.

    Abstract: An x-ray source has multiple electron sources spaced apart from each other along a longitudinal direction that is defined as being parallel to the rotation axis of a rotating anode which is common to all of the electron sources. Each electron source emits electrons that strike the anode at respective strike points that are spatially separated from each other along the longitudinal direction, to produce respective emission centers, from which x-rays are emitted, each emission center being associated with respective ones of the x-ray sources.

    Abstract: A tomosynthesis apparatus has an x-ray source that generates an x-ray beam emanating from a focus, which is received by a flat panel detector. To set a tomosynthesis angle, the position of the central axis of the x-ray beam of the x-ray source is variable. A collimator diaphragm has a diaphragm aperture that limits the expansion of the x-ray beam at the location of the flat panel detector. The collimator diaphragm is arranged in the beam path between the focus and the flat panel detector. The shape and size of the diaphragm aperture are dynamically varied (adjusted) dependent on the changing tomosynthesis angle, such that the expansion of the x-ray beam at the location of the flat panel detector always essentially corresponds to the detector dimensions.

    Abstract: In a method and device for generating a tomosynthetic 3D x-ray image, a number of digital x-ray images of an examination subject are acquired at respectively different projection angles, within a limited angle range, using an x-ray source and a digital x-ray detector. At an initial position for a selected projection angle, a spatially-fixed reference point is projected onto a partial region of the acquisition surface of the x-ray detector. For each further projection angle, a corresponding partial region on the acquisition surface is automatically determined. The tomosynthetic 3D image is reconstruction exclusively using image data from the respective partial regions.
