Abstract

A backscattered human body inspection method and system are disclosed. The method includes the steps of: acquiring a backscatter scan image of a human body to be inspected; distinguishing a human body image and a background image in the backscatter scan image; calculating characteristic parameters of the background image to determine whether the inspected human body carries radioactive substances . Using the solutions of the above embodiments, it is possible to determine whether the inspected human body carries radioactive substances while performing the backscatter safety inspection on the inspected human body. In other embodiments, the approximate location of the carried radioactive material in the human body can also be determined, which improves the efficiency of security inspection.

Description

technical field [0001] The embodiments of the present invention relate to the field of nuclear technology detection, in particular to a human body backscatter inspection method and system applied to human body security inspection and radioactive substance detection. Background technique [0002] X-ray backscatter imaging technology is one of the main technologies in the field of human security inspection. The human body is scanned by X-rays, and a large-area detector is used to receive the backscattered signal. After data and image processing, the scanned image of the scattered object can be obtained. [0003] In addition to guns, knives, explosives, drugs and other prohibited goods, radioactive sources and radioactive substances are also one of the dangerous goods that the human body may carry, and special radioactive substance detection equipment is usually required to detect them. [0004] At present, X-ray backscatter imaging equipment at home and abroad has been widely...
