摘要： In a method for estimating the remaining life span of an X-ray radiator that has been installed in an X-ray apparatus and is operational, under specified test conditions and at time intervals, a measurement value that is indicative for the remaining life span of the X-ray radiator is determined and stored in a memory. A forecasted progression of future measurement values is then forecasted from the instantaneous measurement value and previous measurement values that were determined under identical test conditions, which also are stored in the memory. The forecasted remaining life span of the X-ray radiator is then determined based on the forecasted progression and a limit value that is associated with the individual X-ray radiator, which is stored in the memory.

摘要： A thermionic flat electron emitter has an emitter arrangement with an emitter plate having slits therein that produce serpentine current paths. The emitter arrangement has a structure that, in operation, causes the electron density of the emitted electrons to be lower in the central region of the emitter plate than in a region adjoining the central region.

摘要： A high-performance anode plate for a directly cooled rotary piston x-ray tube is formed of a high-temperature-resistant material such as tungsten, molybdenum or a combination of both materials. In the region of the focal spot path, the underside of the anode plate is shaped, and/or in this region a different highly heat-conductive material is inserted or applied, such that an improved heat dissipation and thus a lower temperature gradient results.

摘要： A monochromator to be used in an X-ray device having an X-ray source is formed by a crystal for spectral restriction of X-rays produced by the X-ray source. The monochromator includes a positioning device that can move the crystal so that it changes the spectral composition of the X-radiation. The crystal can be moved so that it changes the angle between an X-ray path and the crystal, or so that the crystal is removed out of X-ray path or returned into it.

摘要： In an x-ray computed tomography apparatus the source of X-rays and the detector are able to scan a volume of the examination subject in a short time. The X-ray source contains an anode that is elongated in the z-direction, on which the focus travels by a controlled deflection of an electron beam. A primary beam diaphragm is displaced synchronously with the focus movement along the anode. The diaphragm forms a pyramid-shaped X-ray beam which always fully strikes the detector but does not overshot the detector. The detector is formed by a matrix of detector elements.
