摘要： A miniature x-ray tube is cooled using a catheter preferably having multiple small lumens for inflow and outflow of coolant. Inflow may be through an outer lumen(s) in a concentric-extrusion catheter, the liquid turning back at the distal end of the catheter to a proximal flow over the anode end of the x-ray tube and through an inner lumen within which the x-ray tube is positioned. A coolant distribution head may engage with the anode end of the x-ray tube, with small orifices so as to distribute coolant essentially evenly over the anode surface. Temperature and flow rate of the inflowing coolant liquid are balanced so as to optimize heat transfer while efficiently carrying coolant through small lumens without the need for high pressures. Some embodiments use the inflation liquid in an applicator balloon as the coolant, with the liquid actively flowing or, in a simplified system, with the liquid static.

摘要： A cooled radiation emission device has an enclosure in which X-rays are produced. In the enclosure, there is a cathode, an anode situated facing the cathode and rotating on a shaft, and a fixed anode shaft support. The support includes a holding chamber, the shaft of the anode being held in the chamber. The cooling of the tube uses a gallium-indium-tin liquid alloy flow through the anode shaft. This alloy is a conductor of heat and electricity. At the same time as the lubrication of the bearings and the electrical powering of the anode, it provides for cooling of the anode.

摘要： The invention relates to a method of determining a corresponding image of a moving object for a reference image from an image sequence which represents the motion as a sequence of states of motion. To this end, two motion signals, representing the development of the relevant motions, are examined for similarities. Using the similarity function thus obtained, that image in the image sequence can be determined which represents at least approximately the state of motion of the object which is represented in the reference image. Furthermore, the invention relates to a system which is suitable for carrying out the method as well as to a computer program and a computer program product enabling a data processing unit to carry out the method.

摘要： The present invention provides an x-ray source including an electron-generation chamber with an electron beam source that emits electrons and a target chamber with a support structure and a target positioned within the support structure. The emitted electrons travel in a direction substantially parallel to a longitudinal axis extending between the electron-generation chamber and the target chamber towards the target and bombard the target to generate x-rays. The target is movable, while being bombarded with electrons, with respect to the support structure in at least one direction perpendicular to a longitudinal axis.

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： An X-ray tube having a rotary anode which is accommodated in a vacuum-tight housing so as to be rotatable by means of at least one spirally grooved bearing. The mutually cooperating surfaces of the bearing consist essentially of Mo or of an alloy of Mo and W and are effectively wetted by a Ga-alloy serving as a bearing lubricant. In order to extend the life of the X-ray tube, 1 to 4% by weight of Ag and/or Cu are added to the Ga-alloy, as a result of which the formation of crystalline compounds is inhibited.
