摘要： In a method and x-ray device to determine a three-dimensional target image data set showing at least one partial region of interest of an acquisition region, wherein the image data of the three-dimensional target image data set are reconstructed from two-dimensional projection images acquired from various projection directions, first projection images are acquired without a collimation of the radiation source from first projection directions and a three-dimensional overview image data set of the acquisition region is reconstructed from the first projection images. The partial region of interest is selected in the overview image data set. Second projection images are acquired, with collimation at the partial region, from second projection directions, the second projection directions differing from the first projection directions. The target image data set showing the acquisition region and the partial region of interest is reconstructed from all first and second projection images.

摘要： A mammography apparatus has a bed unit on which, during a screening, the patient lies ventrally on a recumbent surface of the bed unit. The recumbent surface has a configuration allowing variable individual parts of the bed unit to be positioned so that the bed position of the patient is optimized and the components of the x-ray unit that are arranged below the bed unit can be positioned and aligned relative to one another such that the base of the breast to be x-rayed is also imaged.

摘要： In a control method and a control unit to control a high-energy, tomosynthesis scan in a contrast agent-assisted dual-energy tomosynthesis, image data of a first tomosynthesis scan are evaluated in order to determine the respective greyscale values for all volume segments. A tube current-time product value for every greyscale value is stored in a memory. For every projection angle, a calculation unit can thereupon calculate a tube current-time product value and acquisition parameters and result with which the second high-energy tomosynthesis scan is controlled.

摘要： In a mammography system with a radiation protection wall, a production method for a radiation protection wall, and a method to operate a mammography system, the radiation protection wall has a further function in addition to the radiation protection. The radiation protection wall additionally serves to present a user interface of a control program to control the mammography apparatus, and can still display the images acquired by the mammography apparatus. The display region of the radiation protection wall is provided in the upper region of said radiation protection wall and can be fashioned as a touchscreen in order to control the mammography apparatus with the detected touch signals.

摘要： In a method to create dual energy x-ray image data of a predetermined volume segment of an examination subject with an x-ray system, a low-energy x-ray image data of the volume segment is created, a high-energy x-ray image data of the volume segment is created, the low-energy x-ray image data is subtracted from the high-energy x-ray image data to create the dual energy x-ray image data. An x-ray filter that consists essentially of titanium is used in the creation of the dual energy x-ray image data.

摘要： A compression device has a compression plate that applies a pressure to a subject on a support plate. The compression plate has a number of elastically-deformable compression plate elements that are substantially transparent for an examination field used with the compression device. In a method for compressing a subject, at least one pressure sensor measures the pressure applied by a compression device to a subject, and wirelessly supplies a signal representing the detected pressure to a control unit, wherein the detected pressure is compared to a stored compression pressure value. The control device adjusts the pressure applied to the subject by the compression device so that the pressure detected by the sensor is equal to the stored compression pressure value.
