    Abstract: A dental x-ray tube head having a housing with an x-ray tube mounted in it, with improved shielding for preventing stray radiation from emanating outside of the path of the primary x-ray beam. The shielding includes an inner hollow element encasing the x-ray tube and having an aperture through which the primary beam projects, with an open end for connecting wires to the x-ray tube. The shielding further includes an outer hollow element which fits over the inner element in such a way as to cover the open end, with clearance for the wires connected to the tube. Both the inner element and the outer element are comprised of a mixture of polypropylene and barium sulfate. The combination of the inner element and the outer element completely surrounds the x-ray tube with the barium sulfate impregnated material, eliminating the use of lead within the tube head, and thereby providing excellent electrical insulation characteristics besides the x-ray attenuation.

    Abstract: A thermal energy storage and transfer assembly is disclosed for use in electron beam generating devices that generate residual energy. The residual energy comprises radiant thermal energy and kinetic energy of back scattered electrons. The thermal energy storage and transfer assembly absorbs and stores an amount of the residual energy to reduce the heat load on other components in the electron beam generating device. The thermal energy storage and transfer device comprises a body portion of a sufficient thermal capacity to permit the rate of transfer of the amount of the residual energy absorbed into the assembly to substantially exceed the rate of transfer of the amount of the residual energy out of the assembly. The assembly also comprises a heat exchange chamber filled with a circulating fluid that transfers the thermal energy out of the assembly. Additionally, in an x-ray generating device, an x-ray transmissive filter suitable for absorbing residual energy is positioned between the anode and an x-ray transmissive window. The filter reduces the exposure of the window to the residual energy. The filter may additionally comprise a coating layer that further reduces the exposure of the window to the residual energy.

    Abstract: The present invention is directed to a radiographic apparatus, and its method of manufacture, that utilizes a single integral housing for providing an evacuated envelope for an anode and cathode assembly. The integral housing is preferably formed from a substrate material, such as Kovar, that has a radiation shielding layer, which is comprised of a powder metal that is deposited with a plasma spray process. The powder metal includes, for example, tungsten and iron, so that the radiation shield layer provides sufficient radiation blocking and heat transfer characteristics such that an additional external housing is not required. In an alternative embodiment, the integral housing is composed of a solidified integrated mixture of metallic powders that function together as both the integral housing wall and the radiation shielding. The integral housing is air cooled, and thus does not utilize any liquid coolant. In addition, the assembly utilizes a dielectric gel polymer material to electrically insulate electrical connections on the housing.
