Channel X-ray security machine perspective imaging map for the object in the perpendicular to the X-ray plane of the projection, in the security check, there is also a limited spatial resolution, can not distinguish the complex background in the superposition of the material.

X-ray computed tomography (CT) technology is an advanced non-destructive detection and evaluation technology, it is through the target object for multi-angle projection perspective scanning, the use of three-dimensional reconstruction algorithms, able to obtain the size of the inspected object, the shape, material and density information, so in the field of health care, industry and explosives detection and other areas have a wide range of applications. CT scanning will be fixed in the slide ring ray source and detector at both ends of the slip ring, rotating through the slip ring. CT scanning fixes the ray source and detector at the two ends of the slip ring, and realizes the multi-angle scanning of the target object in the center through the rotation of the slip ring. Early CT technology is limited by backward reconstruction algorithms, only in the case of the object to maintain motionless scanning of a tomographic information, greatly lengthening the detection time. However, the late 20th century saw the birth of helical CT scanning technology, which allowed the slip ring to rotate while the object continued to move forward, greatly improving scanning efficiency.

CT technology was first applied to the medical field, the industrial field of CT until the 1970s began to gradually research and application, and security field of CT was born in the 1990s, mainly used for explosives and drug detection. Characteristic information of explosives and drugs is reserved in advance in the database of security check Ctrl, when scanning the items, security check CT will measure the characteristic information of the substance and the database characteristics of the information for comparison, the comparison is successful that is issued by the hazardous materials alarm, to achieve the intelligent analysis of the alarm function.

Compared with medical CT and industrial CT, the main features of security CT are:

1. Complex types of inspected objects, mostly smaller items, using low-energy ray sources;

2. In the structure, the use of the inspected object translation, ray source and detector rotation scanning mode, scanning speed requirements are high

Compared with the traditional X-ray security screening machine, the main features of security CT are:

1. No need to open the box when detecting, realizing the rapid, three-dimensional imaging inspection of baggage;

2. Rich display content, able to determine the thickness of the material, and effectively identify hidden and superimposed objects;

3. Can accurately identify explosives and drugs

After nearly 30 years of development, security CT has been widely used in airports and customs. Due to the wide variety of objects to be inspected, security CT will focus on the quality of the image formed by scanning, density analysis and other ways of identification in the face of the massive number of objects to be inspected. Moreover, security CT rotary scanning, three-dimensional imaging, can effectively distinguish between the density of substances and the effective atomic number, accurate positioning, reduce the rate of misidentification, explosives and drugs detection angle and obvious advantages, can make up for the shortcomings of the existing security screening machine.

Our advanced data analysis technology, sophisticated neural network structure, more than a million samples of image reserves and security equipment combined to form an intelligent upgrade, to further create a "new model of intelligent security", to serve the public, so that the world is safer, so that the life of a healthier.
