    Abstract: An anticathode is repeatedly moved along a rotating axis of the anticathode while the anticathode is rotated around the rotating axis. Then, energy beams are irradiated onto a surface portion of the anticathode which is located against a centrifugal force generated from the rotation of the anticathode to partially melt the surface portion through the heating said surface portion near the melting point of the anticathode or over the melting point of the anticathode, thereby generating an X-ray from the rotating anticathode.

    Abstract: An x-ray generating device includes a field emission cathode formed at least partially from a nanostructure-containing material having an emitted electron current density of at least 4 A/cm2. High energy conversion efficiency and compact design are achieved due to easy focusing of cold cathode emitted electrons and dramatic reduction of heating at the anode. In addition, by pulsing the field between the cathode and the gate or anode and focusing the electron beams at different anode materials, pulsed x-ray radiation with varying energy can be generated from a single device. Methods and apparatus for independent control of electron emission current and x-ray energy in x-ray tubes are also provided. The independent control can be accomplished by adjusting the distance between the cathode and anode. The independent control can also be accomplished by adjusting the temperature of the cathode. The independent control can also be accomplished by optical excitation of the cathode. The cathode can include field emissive materials such as carbon nanotubes.

    Abstract translation: X射线产生装置包括至少部分地由具有至少4A / cm 2的发射电子电流密度的含纳米结构的材料形成的场致发射阴极。 由于容易聚焦冷阴极发射电子并显着降低阳极的加热，因此实现了高能量转换效率和紧凑设计。 此外，通过在阴极和栅极或阳极之间脉冲电场并将电子束聚焦在不同的阳极材料处，可以从单个器件产生具有变化能量的脉冲X射线辐射。 还提供了用于独立控制X射线管中的电子发射电流和X射线能量的方法和装置。 独立控制可以通过调节阴极和阳极之间的距离来实现。 独立控制也可以通过调节阴极的温度来实现。 独立控制也可以通过阴极的光学激发来实现。 阴极可以包括诸如碳纳米管的场发射材料。

    Abstract: An X-ray tube anode target assembly having a support shaft connected to a pivot assembly and a movable anode target surface disposed at one end of the support shaft. A first drive assembly is operably arranged with respect to the support shaft to provide oscillatory motion to the anode target about a first axis substantially parallel to the support shaft and drive cylinder operably arranged with respect to the contact element to provide a pivoting motion to the support shaft. A second drive assembly is operably arranged with respect to the drive cylinder to provide an oscillatory motion to the drive cylinder, the second drive cylinder having a cam portion to provide linear motion to the support shaft parallel to the first axis. The target surface is maintained at a substantially constant angle of impingement and maintains a substantially fixed distance from a cathode during target motion.
