Ray-utilized human body security checking method and ray-utilized human body security checking system

Abstract

The invention relates to a ray-utilized human body security checking system and a ray-utilized human body security checking method. The ray-utilized human body security checking method comprises the steps of S1, performing personal identity identification on a checked person; S2, retrieving the accumulated ray scanning dose of a checked person according to an identity identification result; S3, acquiring the single-time ray scanning dose of ray-utilized human body security checking equipment, wherein the single-time ray scanning dose is the rated single-time scanning dose of the ray-utilized human body security checking equipment; S4, calculating the accumulated ray scanning dose of the checked person and the accumulated value of the single-time scanning dose of the ray-utilized human body security checking equipment; and S5, determining whether to perform the ray checking on the checked person according to whether the accumulated value exceeds a dose limit. The ray-utilized human body security checking system and the ray-utilized human body security checking method improve safety in performing ray checking on the human body.

Description

technical field [0001] Embodiments of the present invention relate to the field of radiation human security inspection. Background technique [0002] Radiation human body security inspection is widely used in airports, customs, stations and other places. Commonly used radiographic techniques include X-ray fluoroscopic imaging and X-ray backscatter imaging. X-ray transmission imaging technology refers to the use of X-rays to pass through the human body to be inspected, and the computer analyzes and processes the X-ray signals after passing through the human body to form a perspective image of the human body. This is currently the main technical means for inspecting hidden objects in the human body. X-ray backscattering technology uses a trace X-ray source to scan the subject, and obtains the contour image of the human body surface by receiving the ray signal scattered back from the human body surface. This technology can effectively detect dangerous goods carried by the huma...
