摘要： In three-dimensional computed tomography or three-dimensional rotational X-ray imaging, the acquisition of different spectral measurement data requires subsequent acquisition runs. According to an exemplary embodiment of the present invention, an examination apparatus is provided in which different spectral measurement data are acquired immediately one after another during the same acquisition run by performing a focal spot switching during data acquisition. This may reduce motion artefacts.

摘要： An X-ray source apparatus (100) comprises a cathode (101), comprises an electron beam deflection means including one or more electron beam deflection elements (103) and comprises an anode (102). The cathode (101) is adapted to emit an electron beam (104) towards the electron beam deflection means. The electron beam deflection means is adapted to deflect an electron beam (104) coming from the cathode (101) to a selectable part (110) of the anode (102), wherein the selectable part (110) of the anode (102) is selectable to by activating a single one of the one or more electron beam deflection elements (103), with the single activated electron beam deflection element (103) being arranged at a variable position along a propagation path of the electron beam (104) coming from the cathode, (101) such that the electron beam (104) is deflected to the selectable part (110) of the anode (102). The anode (102) is adapted to generate an X-ray beam (104) when being irradiated by an electron beam (104) deflected by the electron beam deflection means.

摘要： A computed tomography imaging system includes an x ray tube (12, 212) that injects an x ray conebeam into an examination region (14). The x ray tube (12, 212) includes a rotating cylindrical anode (30, 230, 330, 430) having a target outer surface region. The cylindrical anode (30, 230, 330, 430) rotates about a longitudinally aligned cylinder axis (32). Electrons are accelerated toward a selected spot on the target outer surface region of the cylindrical anode (30, 230, 330, 430). Electrostatic or electromagnetic deflectors (64, 68) sweep the selected spot back and forth across the target outer surface region of the cylindrical anode (30, 330, 430). The imaging system further includes a rotating gantry (22) that revolves the x ray tube (12, 212) about the examination region (14) around a rotation axis that is parallel to the cylindrical axis, and an x-ray detector (16) arranged to detect x rays after said x rays pass through the examination region (14).

摘要： An X-ray generator (1) comprises an evacuated and sealed X-ray tube (2), containing an electron gun (3) and an X-ray target (4). An electron beam is produced by the electron gun (3) in which the cathode is at negative high voltage, the electron gun (3) consisting of a filament just inside the aperture (11) of a Wehnelt grid which is biased negatively with respect to the filament. Two sets of beam deflection coils (14), are employed in two planes, mounted between the anode of the electron gun (3) and the focussing lens (15) to centre the beam. Between the focussing lens (15) and the target (4) is an air-cored quadrupole magnet which acts as a stigmator (16) in that it turns the circular cross-section of the beam into an elongated one. This quadrupole (16) can be rotated about the tube axis so as to adjust the orientation of the line focus. The beam can be moved about on the target surface (4) by controlling the currents in the four coils of the quadrupole (16).

摘要： The x-ray source of the present invention comprises a charged particle beam generator (112) and a vacuum enclosure assembly (176). The charges particle beam generator includes only a single electrical connection (803) for providing high voltage to the electron gun. The generated charged particle beam is controlled through a series of dynamic and static focus coils (187, 185) and moved across the inner face of the target (50) by a stepping coil assembly comprising X and Y deflection coils (190) as well as an X step and preferably Y step coils (188). Further, to minimize power usage a control grid pinches off the charged particle beam during the steppimg of the beam.

摘要： X-ray tube (20) includes a rotatable envelope (11) in which is mounted an electron gun (74) at one end and a target anode (36) at the other end. A fixed means (120) for deflecting the electron beam from the electron gun is provided to deflect the electron beam on a fixed path as the envelope (11) of the x-ray tube rotates about an axis. The electron beam being confined to a fixed path (124) results in the electron beam striking various positions of the target anode to provide for improved heat dissipation. The electron beam is deflected along the fixed path using magnetic deflection means including magnetic deflection coils (120) positioned external of the envelope to provide a deflection field transverse to the electron beam. The target anode (36) is cooled by directing a cooling fluid (44,46) on an external side of the target anode.
