    Abstract: 本发明描述一种用于生成X-射线辐射的装置,其包括形成为球形的一部分的阳极(9)。所述装置还包括至少一个虚焦点元件(4),适于发射所生成的光子以产生有用光束场。与先前公知的用于生成-X-射线的具有倾斜阳极表面的X-射线管和装置相比,根据本发明的装置具有更大的实焦点。因此,在假设两种装置的加速电压和每一个阳极表面单位的电子密度相等的情况下,与先前公知的X-射线管相比,根据本发明的装置能够实现每单位时间增加的辐射量。虚焦点元件(4)能够适于具体的应用领域。由于高的光子密度以及可以适于需要的焦点,可以避免时间和几何相关的成像误差。在利用根据本发明的装置生成有用辐射时,在光束场中,光子在质量和能量方面可以均匀分配,这使得在整个有用光束场中实现相等的成像条件成为可能。

    Abstract: The disclosed subject matter includes devices and methods relating to anode assemblies and/or X-ray assemblies. In some aspects, a method of forming an X-ray assembly may include providing an anode base 74 formed of a first material and including a first end. The method may include depositing a second material different from the first material over a first surface of the anode base to form a coated portion 180 of the anode base. The coated portion may be configured such that some backscattered electrons do not travel beyond the coated portion.

    Abstract: A distance (L1) from an X-ray tube central axis (0) to an outer side surface of a cathode electron gun (16) in a direction perpendicular to the longitudinal direction of a filament coil (15) is made less than a distance (P1) from the X-ray tube central axis (O) to an outer side surface of the cathode electron gun (16) in the longitudinal direction of the filament coil (15), and a distance (L2) from the X-ray tube central axis (0) to an X-ray radiation window (20a) in the direction perpendicular to the longitudinal direction of the filament coil (15) is made less than a distance (P2) from the X-ray tube central axis (O) to an X-ray radiation window (20b) in the longitudinal direction of the filament coil (15).
    This configuration makes it possible to position an optical element for collecting X-rays near the focal point of an X-ray tube when using X-rays on a line-focus side, thereby increasing the X-ray collection efficiency.

    Abstract: An electron beam emitting a cathode module of an X-ray tube based on carbon nanotube is provided to focus both electrodes by an electron beam focusing lens and to easily manufacture a module having a cathode of three pole structures and a grid electrode. In an electron beam emitting a cathode module of an X-ray tube based on carbon nanotube, a cathode(5) is based on a carbon nanotube as an electron emission source. A gate unit induces an emission of electrons from the cathode(5). An anode accelerates the electrons emitted from the cathode and generates an X-ray by collision of the electrons. The carbon nanotube is deposited on a substrate(6). A substrate supporting table(7) supports the substrate(6). A grid electrode unit(3) is made of a metal material capable of applying a high voltage. A second insulating layer(10) encompasses a side surface of the grid electrode unit(3) and a bottom portion of the substrate supporting table(7) in a cylindrical shape. A third insulating layer is installed in a shape of a doughnut. An electron beam collecting unit(1) encompassed by the second insulating layer(10) and the third insulating layer in a cylindrical shape is constructed by being modulized as one body.
