Abstract: In a method and apparatus for generation of a digital x-ray image of an examination subject with an x-ray tube and a digital x-ray detector, a preliminary total dose required for correct exposure is determined using prior knowledge and a complete pre-image of the examination subject is acquired with a partial dose that is smaller than the preliminary total dose. A remaining dose is determined from the pre-image by image evaluation. A complete following image is acquired with this remaining dose, and the final x-ray image is assembled from the pre-image and the following image.

Abstract: In a tomographical image reconstruction method and apparatus to generate an image of an examination subject from a number of digital projection data acquired at different projection angles, a first analytical filter kernel (formed by a first analytical function) is determined for a filtered back projection in the spatial frequency range, this first analytical filter kernel approximating, at least in a range of the spatial frequency, a discrete filter kernel iteratively determined for a model. Back projection is implemented with a second analytical filter kernel calculated from the analytical filter kernel and formed by a second analytical function.

Abstract: In a continuous mammography procedure, the breast of a subject is fixed in place in a retention device, and a first x-ray image is generated by irradiating the breast in the retention device. While the breast is still held in the retention device, the first x-ray image is evaluated to define a condition for generating a second x-ray image. The second x-ray image is then generated according to the defined condition, with the breast still in the same position in the retention device.

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.
