    Abstract: The present invention relates to X-ray generating technology in general, in particular, it relates to an anode disk element (1) for an X-ray generating device (21). The generation of electromagnetic radiation may be considered to be quite inefficient, since a substantial part of energy applied to a focal track is converted to heat rather than X-radiation. Thus, a limiting factor in the operation of X-ray tubes is the cooling of the anode element and more specifically the focal track. In the present invention, an anode disk element is provided, with an improved dissipation of heat from the focal track. Thus, the anode disk element may sustain increased heat while maintaining structural integrity. The anode disk element (1) comprises at least a first surface (2) and a second surface (3), with the first surface (2) comprising a focal track (4) and the second surface (3) comprising a conductive coating (5). The anode disk element (1) is rotatable about a rotational axis (6) with the focal track (4) being rotationally symmetrical to the rotational axis (6). The first surface (2) comprising the focal track (4) and the second surface (3) comprising the conductive coating (5) are adjacently arranged.

    Abstract: An X-ray module includes a housing in which an opening portion is formed; an electron gun that emits an electron beam; a target that transmits an X-ray generated when the electron beam is incident on the target and emits the X-ray from an X-ray-emitting surface; an X-ray-emitting window that seals the opening portion, and that transmits the X-ray and emits the X-ray to a first side in an axial direction; and a heat radiating unit disposed outside the housing. The housing includes a surface on which a protrusion protruding to the first side is formed, the opening portion is formed in the protrusion, and the target is disposed in the opening portion. The heat radiating unit includes a first portion extending along the surface and thermally connected to the surface, and a second portion extending from the first portion to a second side opposite the first side.

    Abstract: An X-ray generation apparatus has a housing comprising an evacuated envelope with a rotatable anode target surrounded by an all metal grounded exterior structure and a cooling system. The cooling system comprises a coolant circulating system with heat exchanger and means for circulating a fluid coolant through an interior of the X-ray generating apparatus; a hollow shield structure with center aperture for passing and electron beam; and a cooling block which is disposed proximate to the rotatable anode target and comprises a disk with a plurality of concentric annular channels formed by concentric annular partitions. The shield structure and the disk of the cooling block are made of thermally conductive material. An interior of the shield structure is filled with structures such as pins, fins or pack bed which are made of thermally conductive materials. The fluid coolant is circulated through the shield structure, then into the plurality of channels of the cooling block and via an interior of the housing to the heat exchanger for efficient cooling of the X-ray generating apparatus.

The cathode assembly may be placed within the vacuum enclosure through an opening in the top wall thereof, and comprises a disk which completely covers this opening. The unitary vacuum enclosure and the disk form a radiation shield. A plurality of fins are disposed on the exterior side wall of the vacuum enclosure, and a shroud is attached to the fins to provide additional protection of ambient against radiation. The cathode assembly may be placed through a side wall of the vacuum enclosure. The additional protection against excessive radiation in this design is provided by a shielding member placed in proximity to the anode target. The shielding member extends from the side wall of the enclosure and is substantially parallel to the top wall.
