Abstract: An x-ray source has multiple electron sources spaced apart from each other along a longitudinal direction that is defined as being parallel to the rotation axis of a rotating anode which is common to all of the electron sources. Each electron source emits electrons that strike the anode at respective strike points that are spatially separated from each other along the longitudinal direction, to produce respective emission centers, from which x-rays are emitted, each emission center being associated with respective ones of the x-ray sources.

Abstract: A compact apparatus can form multi X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

Abstract: A cathode shield can comprise a shield body, a pair of tabs for defining a focal spot length, and a lip for concentrically aligning the cathode shield relative to a mounting element and/or an electron source of a cathode assembly. The tabs may be integral with the shield body and spaced a distance apart from each other. The distance may at least partially define the focal spot length of the electron source associated with the cathode assembly. The lip may also be integral with the shield body and extend from the shield body around at least a portion of a perimeter of the shield body so as to define a recess that is configured to receive the mounting element of the cathode assembly.

Abstract: A multi-beam x-ray device has a multi-beam x-ray tube in the form of a polygon, wherein the focal spots of the x-ray radiation are arranged along the polygon sides. An x-ray tube control unit controls the x-ray radiation emission such that an x-ray beam is alternately emitted from each polygon side in a specified sequence. Multiple first diaphragms with at least one respective first diaphragm aperture are arranged such that they can move into the beam path of the x-ray tube. A first diaphragm, whose first diaphragm aperture limits the cross section of the x-ray beam emitted from the x-ray tube, is associated with every polygon side. A number of slice images can be generated from different directions without a movement of the x-ray tube.
