    Abstract: In a method and examination apparatus for generating three-dimensional, multiply resolved volume images of an examination subject on the basis of two-dimensional projection images that can be registered with the apparatus, as radiation images obtained with a radiation source and a radiation receiver in an exposure procedure of the examination subject, a set of two-dimensional projection images is registered, one part of the set being registered with low resolution and one part of the set being registered with high resolution, transforming the high-resolution projection images are transformed so as to have the same scale, the same sampling rate and the same resolution as the low-resolution projection images (downscaling), and a three-dimensional volume image with low resolution is generated on the basis of the low-resolution projection images as well as the transformed projection images and a high-resolution volume image is generated on the basis of the high-resolution projection images.

    Abstract: A mammography apparatus has at least one x-ray source to emit x-ray radiation and an x-ray detector with a number of pixels. The mammography apparatus is designed so that the x-ray radiation is emitted into the breast tissue of a patient at a number of positions, and the x-ray radiation is detected by the x-ray detector after it has passed through the breast tissue. The positions have different distances from the shoulder-to-shoulder axis of the patient.

    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 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.
