摘要： 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.

摘要： 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.

摘要： In a method for producing a stereotactic image of a patient fixed in a mammography device for a biopsy, a computerized control and evaluation unit waits for a start signal to be given by an operator, and after receipt of the start signal, automatically implements the following steps. An x-ray apparatus of the mammography device is positioned in a first predetermined imaging position, and a first image of the patient is acquired with the x-ray apparatus in this position. The x-ray apparatus is then pivoted into a second imaging position, different from the first, and a second image of the patient is acquired at the second position. The first and second images are acquired to form a stereotactic image of the patient.

摘要： In a method and an associated device for generation of digital x-ray image exposures of an examination subject with an x-ray source and a digital x-ray detector for a stereotactic biopsy, wherein, for one or more x-ray image acquisitions of the examination subject with a biopsy device, acquisition and image processing parameters are used that have been determined from an x-ray image exposure of the examination subject without the biopsy device (7). The influences that are disruptive for an optimal x-ray image, for example of metallic biopsy devices, can thereby be avoided.
