Abstract: Methods and an x-ray system for dynamically regulating x-ray dose. An x-ray beam is generated and collimated at a source collimator and detected after the x-ray beam traverses an inspected object. A filter may be dynamically interposed by translation of the filter between a focal spot of the source and the source collimator in such a manner as to maintain the portion of the x-ray beam that traverses the inspected object below a specified limit. Alternatively, an aperture of the source collimator may be varied in size or position relative to the focal spot.

Abstract: Disclosed herein are methods of sorting coal into multiple fractions based upon x-ray absorption and size characteristics in order to remove rocks and other contaminants of various sizes from coal. The use of such dry processing of coal is desirable as it reduces pollution and transportation costs. The multi-fractional sorting of coal is a more efficient manner for identifying and removing rock and contaminants from coal.

Abstract: An x-ray tube (16) suitable for use in a computed tomography (CT) scanner (10) includes an envelope (42) which defines an evacuated chamber. An anode (40) and a cathode assembly (70) are disposed within the chamber. The anode defines a target area (56) which is struck by electrons (52) emitted by a filament (54) of the cathode assembly and emits x-rays (46). The target area lies partially on a first annular portion (80) which is disposed at first angle (a) relative to a plane perpendicular to an axis of rotation (R) of the anode, and partially on a second portion (82,120) which is radially spaced from the first portion and disposed at a second angle (B), relative to the plane. The second angle is greater than the first angle. The portions of different slope allow the x-ray tube to take advantage of a shallow angle, while minimizing the heel effect.

Abstract: The invention relates to an X-ray tube which includes a device for at least substantially protecting an object to be examined against the incidence of undesirable X-rays (E) which can be produced notably by the decay of a residual or surplus charge present in a high-voltage circuit after an X-ray exposure. To this end there is provided at least one device (341, 342) for deflecting and/or defocusing the electron beam (E) produced by the residual and/or surplus charge in such a manner that at least it is not incident to a significant extent on a region (22) of an anode (2) wherefrom X-rays excited thereby are directed towards an object to be examined.

Abstract: An x-ray emitting window is formed at a front end face, and a taper surface tilted with respect to the x-ray emitting direction is formed near the emitting window, whereby an object to be inspected can be prevented from abutting against the front end face even if the object is pivoted about an axis intersecting the emitting direction while the object is disposed closer to the x-ray emitting window. As a consequence, while the object is disposed closer to the x-ray emitting position, the orientation of the object can be changed. Therefore, when inspecting the internal structure of the object and the like by irradiating the object with x-rays and detecting the x-rays transmitted through the object, not only a magnified penetration image of the object with a high magnification rate is obtained, but also the internal structure of the object and the like can be verified in detail by changing the orientation of the object.

Abstract: An apparatus and method for reducing the incidence of electric field stress on portions of insulating structures within high voltage devices is disclosed. Each of the embodiments disclosed herein modifies the conductive properties of the insulating structure surface in a non-uniform manner such that the distribution of voltage potential along the surface thereof is more fully equalized during operation of the high voltage device. This, in turn, reduces the per unit stress on the insulating structure caused by the electric field of the high voltage device. Though embodiments of the present invention are preferably directed to utilization in x-ray tube devices, a variety of high voltage devices may benefit from application of the disclosed matter.
