Abstract

The invention provides a pencil beam X ray tube and a back scattering detection device. The pencil beam X-ray tube comprises a shell; an anode, wherein at least one end of the cathode is set in the shell, and the end face of the at least one end is not vertical to a length extension direction of the cathode; a target which is set on the end face of the at least one end of the anode; a cathode, wherein the cathode is configured to face the target and can emit electrons to the target; and a pencil beam module which is configured nearby the at least one end of the anode and is used for modulatingX rays generated by the target into pencil X beams, wherein the pencil X beams are emitted from the pencil beam X ray tube.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of radiation generation, in particular to pencil beam X-ray tubes and backscatter detection equipment. Background technique [0002] Backscatter imaging technology has been widely used in the field of safety inspection of human body, goods and vehicles due to its advantages of low radiation dose, good safety and sensitivity to light materials. The backscatter imaging technology uses a pencil beam scanning method, so the fan beam or cone beam generated by a conventional X-ray tube needs to be modulated into a pencil beam. [0003] However, a conventional pencil beam scanning device includes an X-ray tube assembly, a high-voltage power supply, a pencil beam scanning and its driving mechanism, etc., and the components are relatively large and scattered. This limits its application in small or portable products. Contents of the invention [0004] According to an aspect of the present d...
