Embodiment Construction

[0045] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0046] see Figure 1 to Figure 4 , the embodiment of the present invention discloses a cathode assembly 100, and the cathode assembly 100 is applied to an X-ray light source and a CT device having the light source. The cathode assembly 100 is a hot cathode, which can emit electrons after being energized and heated, and generate X-rays through the generated electrons. The cathode assembly 100 of this embodiment includes a ceram...

Abstract

The invention provides a cathode assembly and an X-ray light source with the same and CT equipment. The cathode assembly comprises a ceramic plug and a ceramic socket, wherein the ceramic plug is provided with oppositely arranged first end and second end, four connection terminals are arranged on the outer end surface of the first end and a convex locating part is arranged on the peripheral surface of the first end; an inner cavity is formed in the ceramic plug, an opening of the inner cavity is located at the second end, a cathode is arranged in the inner cavity and is provided with a filament and the filament is provided with a positive wire and a negative wire; a grid mesh is arranged on the end surface of the second end and is provided with a grid voltage signal line; a cathode surface lead is arranged on the surface of the cathode; the positive wire of the filament, the negative wire of the filament, the grid voltage signal line and the cathode surface lead are electrically connected with one connection terminal separately; the ceramic socket is provided with four connection cylinders; the ceramic socket can be in contact with the first end of the ceramic plug; and the four connection cylinders can be electrically connected with the four connection terminals.

Description

technical field [0001] The invention relates to a cathode assembly, and also relates to an X-ray light source and a CT device with the cathode assembly. Background technique [0002] X-rays are widely used in industrial non-destructive testing, safety inspection, medical diagnosis and treatment and other fields. In particular, X-ray fluoroscopy imaging equipment made by utilizing the high penetrating ability of X-rays plays an important role in every aspect of people's daily life. The early days of this type of equipment were film-type plane perspective imaging equipment. The current advanced technology is digital, multi-view and high-resolution stereoscopic imaging equipment, such as CT (computed tomography), which can obtain high-definition three-dimensional graphics or slices Graphics, are advanced high-end applications. [0003] In the existing CT equipment, the X-ray generating device needs to move on the slip ring. In order to increase the inspection speed, the X-ray...
