Abstract

The invention provides an X-ray tube comprising a first inner cylinder with both ends sealed. The inner portion of the first inner cylinder is set to be of a vacuum structure; a first sealing end of the first inner cylinder is provided with a high pressure receiver, a cable input of which is arranged outside the first sealing end; and an outer wall of an anode tube coaxially disposed inside the first inner cylinder is provided with a plurality of through holes disposed along the radial direction. The X-ray tube also comprises a cathode assembly comprising a cathode holder and a filament. Both ends of the cathode holder are respectively connected with the high pressure receiver and the anode tube; the filament electrically connected with the cathode holder axially extends along the anode tube a free end of which is provided with an electrical protective cover bonded with the anode tube and the filament. When the high pressure receiver receives energy, electricity is transmitted to the filament to generate electrons. The inner wall of the anode tube is bombarded during the injection of the electrons, and generated X-ray injects out of the anode tube. The surface of the anode tube transmits and reflects X-ray energy so that X-ray radiation energy and radiation efficiency are improved.

Description

Technical field [0001] The invention relates to the technical field of radiation generating devices, and more specifically, to an X-ray tube. Background technique [0002] With the traditional X-ray generating device, when the device is energized, the cathode generates electrons, and the electrons bombard the transmission type target, thereby generating X-rays in the opposite direction of the transmission type target. [0003] The energy and efficiency of X-rays generated by this kind of device are low, and in practical applications, it affects the efficiency and energy requirements of its use. [0004] Therefore, how to improve the efficiency and energy of X-ray emission is an urgent problem to be solved by those skilled in the art. Summary of the invention [0005] In view of this, the present invention provides an X-ray tube to improve the efficiency and energy of X-ray emission. [0006] In order to achieve the above objective, the present invention provides the following technica...
