    摘要: Described herein are methods and systems relating to an x-ray generation system. In some embodiments, the system includes an electron beam acceleration region that generates an electron beam and accelerates electrons in the beam and a radiation generation region that (i) receives the electron beam and (ii) generates an electric field having an energy of greater than about 10E7 V/m without electrical breakdown of vacuum gaps. The electric field is configured to decelerate electrons in the electron beam sufficiently to generate x-ray energy.

    摘要: An electron source is formed on a silicon substrate having opposing first and second surfaces. At least one field emitter is prepared on the second surface of the silicon substrate to enhance the emission of electrons. To prevent oxidation of the silicon, a thin, contiguous boron layer is disposed directly on the output surface of the field emitter using a process that minimizes oxidation and defects. The field emitter can take various shapes such as pyramids and rounded whiskers. One or several optional gate layers may be placed at or slightly lower than the height of the field emitter tip in order to achieve fast and accurate control of the emission current and high emission currents. The field emitter can be p-type doped and configured to operate in a reverse bias mode or the field emitter can be n-type doped.

    摘要: An X-ray tube includes a cathode, an anode, and a deflection device. The cathode and the anode generate an electron beam that is directed toward a target area of the anode to generate X-ray radiation through electrons of the electron beam impinging the target area. The deflection device controls the electron beam such that the electrons hit the anode at different focal spot positions. The deflection device provides gradual deflection for a stepless transition between monoscopic viewing and stereoscopic viewing. For monoscopic viewing, the X-ray radiation is generated from a single focal spot position. For stereoscopic viewing, the X-ray radiation is generated from two focal spot positions spaced apart in a first stereo-direction transverse to a viewing direction. The deflection device provides gradual deflection for a stereo focal spot position in a second stereo-direction, which is transverse to the first stereo-direction and the viewing direction.
