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： In a method for operating an x-ray device, an x-ray beam is generated at a focal spot of a rotary anode that is rotatable around a rotation axis, and the x-ray beam is gated with a slit-shaped diaphragm to produce a fan-shaped x-ray beam, that is moved through an examination region in the manner of a scan. To improve the image resolution, the fan-shaped x-ray beam can be moved over the examination region essentially in the direction of the rotational axis of the rotary anode by tilting the x-ray tube on the focal spot, with the x-ray tube being tilted on the focal spot so that the fan-shaped x-ray beam is always gated from the region of the overall emitted x-ray beam having the highest image resolution or the highest image definition in the movement through the examination region.

摘要： To reduce the rotational power, an apparatus with a rotational body that is rotationally driven in a fluid-filled housing a rotational directing body is provided between the rotational body and the housing, which is rotatably supported coaxially with respect to the rotational body. The rotational directing body is configured such that in operation it rotates at an intermediate rotational frequency in comparison to the housing and the rotational body. The apparatus is particularly an X-ray radiator having a cathode and anode that are mounted in a vacuum tube in a spatially fixed manner in relation to the tube, the vacuum tube being rotationally driven as a rotational body in a coolant housing.

摘要： A rotating envelope radiator has a radiator housing surrounded by an external housing to form an intervening space in which a coolant flows. To prevent the formation, at high rotational frequencies, of reverse flows of the coolant in the intervening space, a flow conductor structure is provided in the intervening space that counteracts the formation of tangential flow components in the coolant.

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.
