Abstract: The invention relates to an X-ray examination apparatus in which the X-ray detector 1 and the X-ray source 2 are subject to keeping the temperature constant and to cooling by way of a common cooling circuit. To this end, a cooling medium of constant temperature is applied to the X-ray detector 1 in order to make the X-ray detector 1 operate at uniform ambient temperatures. The temperature of the cooling medium, thus increased a first time, still suffices to perform cooling of the X-ray source 2. Consequently, the heated cooling medium, after application to the X-ray detector 1, is applied to the X-ray source 2 where a second exchange of heat takes place, so that at the same time the X-ray source 2 is cooled without utilizing an additional cooling circuit. This offers the advantage that relevant X-ray examination apparatus may have a simple construction, that the electronic components used in the construction have a correspondingly prolonged service life due to the constant low temperature, and that the apparatus can operate with a higher mean power as a result of the cooling.

Abstract: A method and device for cooling and electrically-insulating a high-voltage, heat-generating component, for example, an x-ray tube (1105) for analyzing fluids by means of x-ray fluorescence. The device includes an x-ray source (1100) including an x-ray tube (1105) having improved heat-dissipating properties due to the thermal coupling of the x-ray tube with a thermally-conductive, dielectric material (1150). The device may include a base assembly (1135) mounted to the component for conducting heat away from the component while electrically isolating the component. In one aspect of the invention, the base assembly includes two copper plates (1140, 1145) separated by a dielectric plate (1150). The dielectric plate minimizes or prevents the leakage of current through the base assembly (1135). One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.

Abstract: A system and method for improving cooling of a heat-generating component in a closed-loop cooling system is shown. The system comprises a venturi having a throat which is coupled to an expansion tank that is exposed to atmospheric pressure in the embodiment being described. The venturi, when used with a pressure switch, can operate to determine a flow rate which can be used to generate a signal which in turn is used to activate or deactivate one or more of the components, such as the heat-generating component, in the system. Advantageously, the design of the embodiment described has a convenient system which utilizes a pressure switch, thereby eliminating the need for a differential pressure switch of the type used in the past.

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.
