Abstract

The embodiment of the invention provides a distributed multi-focus pulse X-ray light tube and CT equipment. The X-ray light tube comprises an anode, a plurality of cathodes and focusing electrodes which correspond to the cathodes and are distributed in a convergent state, the focusing electrodes distributed in the convergent state can enable electron beams emitted by the cathodes to converge towards the center of the anode target. In the embodiment of the invention, due to the focusing electrode in the convergent state, electron beams emitted by the plurality of cathodes can converge to the center of the anode target; therefore, after the electron beams emitted by the plurality of cathodes are focused by the respective corresponding focusing electrodes and then enter the anode, a pluralityof relatively dense focuses can be generated on the anode target, so that the imaging quality of X-rays is improved, and different imaging application occasions are met.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a distributed multi-focus pulsed X-ray light tube and CT equipment. 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) equipment, which can obtain high-definition three-dimensional graphics or Slicing images is an advanced high-end application. [0003] Since the CT equipment is equipped with a DC working X-ray light tube, detector, cooling system, etc., the X-ray tube a...
