Luggage safety inspection device and inspection method thereof

Abstract

The invention discloses a baggage safety inspection device and an inspection method thereof, comprising a conveyor belt, a DR ray generator, a DR detector, a CT ray generator, a CT detector, a computer, and an object to be measured; the object to be measured is placed at the end of the conveyor belt The side of the conveyor belt near the end of the object to be measured is fixed with a DR ray generator and DR detector; the side of the conveyor belt far away from the end of the object to be measured is symmetrically installed with a CT ray generator and a CT detector, and the computer is connected to the DR detector respectively. Connected with the CT detector, it is used to process and reconstruct the signal fed back by the DR detector and the CT detector, and to control the working status of the conveyor belt, the DR ray generator, the DR detector, the CT ray generator and the CT detector. The invention uses the imaging results of the front-end DR system to determine the imaging strategy of the CT imaging system, realizes the intelligent optimization of the CT image quality, and at the same time speeds up the security inspection, making up for the defects of the traditional security inspection equipment and its detection method.

Description

technical field [0001] The invention relates to a device for safety inspection of baggage items, which belongs to the technical field of radiation detection. Background technique [0002] With the increasingly severe international security situation, airports and stations are paying more and more attention to security inspection work, which also puts forward higher requirements for related security inspection equipment. [0003] X-ray projection imaging technology is widely used due to its advantages of being able to quickly detect passenger luggage without opening the box. At present, the equipment using this technology can be roughly divided into two categories: DR and CT. [0004] DR adopts the traditional static scanning technology, which can display the two-dimensional plane image of the inspected object, and has the advantages of fast speed, low cost and simple structure. In recent years, the development of dual-view DR and dual-energy DR technology has greatly strengt...

Problems solved by technology

But relatively, it also has problems such as slow speed, high cost, and low resolution.

[0006] However, in the actual security inspection, CT equipment generally has an independent DR imaging system, so it can perform CT and DR imaging inspections on luggage items at the same time, but the connection between the CT imaging system and the DR imaging system is only able to display the images of the two. The relative positional relationship of , does not involve the intelligent selection of scanning strategy and scanning parameters
