Abstract: An encapsulated stator assembly for use in stator-driven devices is disclosed. The encapsulated stator assembly includes a stator and a covering portion that envelops the stator. The purpose of the covering portion is multi-fold: first, the covering portion serves as a means for mounting and securing the stator, such as within the outer housing of an x ray tube. Second, the covering portion is thermally conductive to enable heat produced by the stator during operation to be dissipated to the outer housing of the x-ray tube thereof. Additionally, the covering portion can include an x-ray absorbent material to reduce x-ray emission from the x-ray tube. Though x-ray tubes represent one advantageous application, the encapsulated stator assembly of the present invention can be used in a variety of motor and stator-driven devices. The encapsulated stator assembly is especially well suited for use in dirty or dusty environments.

Abstract: An integral cathode (200) for use with x-ray devices (102). The integral cathode (200) includes an emitter (202) made of a refractory metal such as tungsten, preferably doped with rhenium to afford malleability during constructions and assembly. The integral ctahode (200) also includes a support cartridge (204), preferably composed of an electrically non-conductive material such as ceramic, in which the emitter (202) is received. The support cartridge (204) electrically isolates the cathode (200) from the other components and structures of the x-ray device (102). Additionally, the support cartridge (204) serves to impose, and maintain, a parbolic curve in the emitter (202). The parabolic form of the emitter (202) naturally shapes an electron beam by causing electrons discharged from the emitter to converge at a focal spot (106). In this way, both the emission and focusing functions of the cathode (200) are integrated and performed by a single part.

Abstract: An X-ray tube is described having a filament for generating electrons (5), a cathode, and an anode (8) which comprises an elongate member (17) having a fixed point relative to the sealed housing of the tube and an end that is moveable relative to the sealed housing. The longitudinal axis of the elongate member in a rest position is laterally displaced relative to the path of the accelerating electrons, whereby a spherical target surface on the moveable end of the member may be moved relative to the impinging electrons such that the spatial location of X-ray generation in the tube is invariant relative to the sealed housing, thereby spreading localised heating caused by the X-ray generation over a greater portion of the target surface. The member is typically driven such that the anode precesses about the X-ray beam.

Abstract: It is described an X-ray tube (205), in particular for use in computed tomography, comprising an electron source (250), for generating an electron beam (255), an electron deflection device (256) for deflecting the generated electron beam (255), a control unit (257) being coupled to the electron deflection device (256) for spatially controlling the deflection, and an anode (206), which is arranged such that the electron beam (255) impinges onto a focal spot of a surface of the anode (206). Thereby the anode (206) is movable along a z-axis in an oscillating manner, the surface of the anode (206) is oriented oblique with respect to the z-axis, and the control unit (257) is adapted to spatially control the focal spot (255 a) in such a manner that the focal spot moves essentially in a discrete manner between a first focal spot position (106a, 406a) having a first z-coordinate and a second focal spot position (106b, 406b) having a second z-coordinate being different from the first z-coordinate.

Abstract: A bearing assembly (400) for a rotating anode (206) x-ray device. The bearing assembly (400) includes a shaft (402) having a flange (402B) at one end for attachment of the anode (206) thereto. The shaft (402) defines front and rear inner races (402D, 402E) and includes a plurality of extended surfaces (414, 416). Front and rear outer race elements (404, 406) define front and rear outer races (404B, 406A), respectively, corresponding to the front and rear inner races (402D, 402E), respectively, defined by the shaft (402). The front and rear outer race elements (404, 406) cooperate with the shaft (402) to confine front and rear ball sets (410, 412) which facilitate rotary motion of the shaft (402). A spacer (408) including extended surfaces (414, 416) assists in the positioning of the front and rear outer race elements (404, 406) in a bearing housing (500). The extended surfaces (414, 416) of the shaft (402) and spacer (408), in conjunction with emissive coatings provided on various portions of selected components of the bearing assembly (500), facilitate a relative improvement in heat transfer out of the bearing assembly (500).
