Abstract: An x-ray tube has a vacuum housing containing an electron-emitting cathode and an anode on which the electron beam, accelerated with an electrical field, is incident. The x-ray tube contains a magnet system which generates a main magnetic field with spring focus for deflecting and focusing the electron beam such that the focal spot on the incident surface of the anode can be azimuthally varied. A coil is located spatially separate from the main magnetic field and the alignment of the focal spot relative to the incident surface can be influenced therewith. The coil is fashioned and arranged such that a non-uniform magnetic field that effects a parallel alignment of the focal spot in the spring function is generated therewith.

Abstract: A fluid-cooled x-ray tube has a closed coolant circuit in which coolant circulates for the elimination of the generated heat. In order to improve the cooling capacity, micro-capsules are added to the coolant that contain a phase-change material (PCM). The micro-capsules have a size of approximately 5 nullm through 20 nullm in diameter.

Abstract: The invention relates to an X-ray source that is provided with a liquid metal target and an electron source (3) for the emission of an electron beam (4) through a window (23) of a duct section (51) wherethrough the liquid metal target flows in the operating condition. The X-ray source is notably characterized in that the duct section (51) is formed by a first duct segment (10, 20) that includes the window (23) and wherethrough the liquid metal target flows, and by a second duct segment (30, 40) wherethrough a cooling medium flows and which is connected to the first duct segment in such a manner that the area in which the electron beam acts on the first duct segment is cooled.

Abstract: Geometry of a tomosynthesis system including a detector and an x-ray source is determined using fiducial markers with non-determined positions. The geometry is determined by arbitrarily identifying at least two markers within an imaged volume, at different relative distances between the detector and the x-ray source, without having projections located on a straight line for all different source positions, and locating the projections of the markers within at least two images acquired of the imaged volume. The at least two images correspond to different positions of a focal spot of the x-ray source.

Abstract: 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.

Abstract: A rotating anode is mounted on a shaft of an X-ray tube by means of a ring. The ring allows expansion and reduces the hyperstatic state of the assembly. The ring has the shape of a diabolo, preferably that of a hyperboloid structure generated by revolution. The ring dampens vibration phenomena in a shaft bearing the rotating anode and reduces noise-creating phenomena.
