    摘要: An x-ray tube has an anode and an electron emitter from which an electron beam emanates, the electron beam impinging the incident surface of the anode in a focal spot from which a useful x-ray beam emanates. At least in the region of its electron-emitting surface, the electron emitter is formed of an electron-emitting material that has a lower electron affinity than tungsten (a low-temperature emitter). Further, an apertured diaphragm at anode potential is arranged between the electron emitter and the anode and through which the electron beam passes. As electron-emitting material, the electron emitter contains lanthanum hexaboride (LaB.sub.6) or an alloy of the systems iridium/cerium (Ir/Ce) or iridium/lanthanum (Ir/La) systems.

    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 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: 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.

    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 an imaging method and a tomosynthesis apparatus, a two-dimensional low-energy image of the predetermined volume segment is obtained after administration of a contrast agent, followed by a two-dimensional high-energy image and then a high-energy tomosynthesis of the predetermined volume segment is obtained with a high total radiation dose that is significantly higher than the low radiation dose. The two-dimensional low-energy image is subtracted from the two-dimensional high-energy image to generate a result with which the concentration of the contrast agent is visible. Additionally, in a time interval in which an enrichment or a washing-out of the contrast agent occurs within the predetermined volume segment, a tomosynthesis of the predetermined volume segment is automatically implemented to show the concentration of the contrast agent in the predetermined volume segment.
