Distributed X-ray source and control method thereof

Abstract

The invention provides a distributed X-ray source and a control force method thereof. Distributed X-ray sources include distributed X-ray tubes and cathode controllers. A distributed X-ray tube includes a housing; A cathode group comprising a plurality of cathodes; An anode comprising a plurality of targets aligned one by one with a plurality of cathodes such that the plurality of targets receiveelectron beams from the plurality of cathodes to generate a plurality of X-rays; And a cathode lead terminal assembly including a plurality of cathode lead terminal assemblies, each cathode lead terminal assembly including a plurality of terminals electrically connected to the cathode, respectively. The cathode controller is electrically connected to a cathode lead terminal assembly through the cathode cable and configured to apply an operating voltage to the cathode through the cathode cable, respectively, to generate the electron beam. The cathode controller is electrically connected to thecathode lead terminal assembly through the cathode cable and configured to apply an operating voltage to the cathode through the cathode cable, respectively, to generate the electron beam.

Description

technical field [0001] The present invention relates to an X-ray source, more particularly to a distributed X-ray source and a control method thereof. Background technique [0002] X-rays are widely used in industrial non-destructive testing, safety inspection, medical diagnosis and treatment and other fields. The device that generates X-rays is called the X-ray source, and usually consists of X-ray tubes, power supply and control systems, auxiliary devices such as cooling and shielding, etc. The X-ray tube consists of three main parts, the cathode, the anode and the casing. The cathode generates an electron beam, which is accelerated by the high-voltage electric field between the cathode and the anode, and hits the target on the anode, thereby generating X-rays. [0003] A multi-target X-ray source (or called a distributed X-ray source) in the prior art is an X-ray source that has multiple cathodes, multiple targets, and can generate X-rays from multiple different positio...

Problems solved by technology

If you want to adjust the working sequence, you need complex logic design or hardware settings for the cathode controller

In the multi-point X-ray source realized by scanning the electron beam current generated by a single cathode, each X-ray target point can only generate X-rays sequentially, and it is difficult to realize that a multi-point X-ray source with multiple cathodes can control the X-rays of each target point. The working mode of flexible adjustment of the ray emission sequence
