摘要： Precise alignment of the focal spot position on an x-ray CT system is achieved using a deflection coil that produces a magnetic field which acts on the electron beam path in the x-ray tube. A variable current power supply drives the deflection coil and is controlled by input signals to align the focal spot at a static reference position, to correct for focal spot drift between scans, and to wobble the focal spot position during a scan or between scans.

摘要： An apparatus for determining the quality of X-ray tubes by analyzing filmed images of the focal spots produced by the tubes. In an exemplary embodiment of the apparatus, a slide scanner receives a filmed focal spot from an X-ray tube and scans it to produce a digital version of the focal spot. The digital focal spot is then analyzed by a personal computer to determine parameters relating to the focal spot such as its background and peak optical density, line spread function, modulation transfer function, skew, and loading. These parameters are then compared to parameter standards to determine whether the X-ray tube should be accepted or rejected under current quality standards.

摘要： An X-ray tube comprises an anode assembly having an associated anode and a cathode assembly for providing a focused electron beam directed to the anode. An anode target, associated with the anode assembly, accelerates the electron beam and produces X-rays upon electron impact with the anode target. Off-focal radiation tends to be most intensely emitted by the top surface of the target. In conventional X-ray tubes, the off-focal radiation as seen by the detector encompasses almost the entire top surface of the target assembly. In accordance with the present invention, the anode target comprises a cut-out top surface for reducing off-focal radiation, by blocking the off-focal radiation from the top surface from reaching the detector. Blocking the radiation produced at the top surface becomes more important as the ratio of the track area visible at the detector decreases with respect to the top surface area.
摘要翻译： X射线管包括具有相关阳极和阴极组件的阳极组件，用于提供指向阳极的聚焦电子束。与阳极组件相关联的阳极靶加速电子束并在与阳极靶电子碰撞时产生X射线。局部放射线趋于由靶的顶面最强烈地发射。在常规的X射线管中，由检测器所看到的非焦距辐射几乎涵盖了目标组件的整个顶表面。根据本发明，阳极靶包括用于通过阻挡来自顶表面的偏焦辐射到达检测器来减少焦点外辐射的切除顶表面。阻挡在顶表面处产生的辐射变得更加重要，因为检测器处可见的轨道区域的比率相对于顶表面积降低。

摘要： X-ray tube electron beam focusing utilizing a cathode having a large cavity therein in which an electron cloud is generated and which is shielded from the primary electric field between the cathode and the anode. The electron cloud flows from the cavity through a small narrow passage and into the primary electric field. An opposed spaced apart pair of electrical grids each comprising an array of individual electrode segments have selected opposed segments electronegatively biased to change the cross-section of the passing electron stream therebetween. The altered cross-section of the electron stream determines the size of the focal spot of the electron beam impacting the target anode.
