Abstract: An X-ray tube includes an anode that conducts a high voltage that can be greater than 120 kV, and in particular greater than 300 kV, and heats up during operation. The anode is connected in a thermally conductive way to a heat sink, which has a base body composed of a metal with a heat absorbing surface for coupling to the anode as a heat source and a heat dissipating surface that is enlarged by means of heat dissipating elements that are connected to the base body. The heat dissipating elements are composed of an electrically insulating material having a thermal conductivity on the same order of magnitude as that of the metal of the base body, and have a height (H) starting from the base body of the heat sink so that there is a sufficient insulation breakdown resistance relative to the surroundings of the X-ray tube.

Abstract: The present invention relates to an X-ray tube (30) with an anode (36) that conducts a high voltage, preferably greater than 120 kV, particularly preferably greater than 300 kV, and heats up during operation, wherein the anode is connected in a thermally conductive way to a heat sink (4), which has a base body (10.4) composed of a metal with a heat absorbing surface (12.4) for coupling to the anode (36) as a heat source (36) and a heat dissipating surface (14.4) that is enlarged by means of heat dissipating elements (16.4) that are connected to the base body (10.4), wherein the heat dissipating elements (16.4) are composed of an electrically insulating material having a thermal conductivity on the same order of magnitude as that of the metal of the base body (10.4), and wherein the heat dissipating elements (16.4) have a height (H) starting from the base body (10.4) of the heat sink (4) so that taking into account the high voltage and an insulating medium surrounding the heat dissipating elements (16.

Abstract: The present invention provides system, devices, and methods for scanning an object while avoiding radiation exposure. For example, the present invention provides systems comprising a scanning device with input and output openings, and a safety sensor adjacent to the input or output opening that sends a signal that turns off or physically blocks electromagnetic radiation if the presence of an invading element (e.g., human hand) is detected by the safety sensor.

Abstract: A radiation-shielded door is provided, especially for use in an X-ray testing device. Radiation shielded closures in the form of lead curtains are disadvantageous in that they graze the object to be tested, thereby impairing the same and no longer covering the entire opening of the radiation tunnel. These disadvantages are avoided by using a radiation-shielded door which is configured by at least two movably arranged, radiation-absorbing lamellae forming the door, the faces of which are levers interlinked to give a lazy tongs-type mechanism.
