The working principle of X-ray security inspection equipment

        With the rapid development of social economy and science and technology, the application of X-ray has been extended to many industries from the initial medical application to the current security application. So, do you really understand the working principle of X-ray security inspection equipment? Where is the X-ray security inspection equipment used. The next article will briefly help you answer the above questions.

The working principle of X-ray security inspection equipment

        The security inspection machine is completed by using the conveyor belt to send the checked luggage and items into the crawler channel. After the item enters the security inspection machine channel, the detection device sends relevant information to the control unit, and the control unit triggers the X-ray source to emit X-rays. After passing through the collimator, the X-rays form a very narrow fan-shaped beam, which passes through the luggage items on the conveyor belt and falls onto the detector. The detector converts the received X-rays into electrical signals. These very weak current signals are amplified and quantified and sent to the industrial control computer for further processing through the universal serial bus., and obtain high-quality images after complex calculation and imaging processing.

        All items are presented by X-ray machine with images, which can display images of different colors on the screen according to the degree of absorption of X-rays by the objects. In simple terms, orange represents organic substances, such as food, plastic, etc.; books, ceramics, etc. are displayed in green; inorganic substances or some metals are displayed in blue, and impenetrable substances are displayed in black. At this time, the security inspector quickly looked at the X-ray scanned fluoroscopic image, and can judge whether there is contraband by virtue of rich experience.

X-ray application

Medical treatment

        Medical diagnostic X-ray machine is one of the commonly used auxiliary examinations in medicine. X-ray examination methods commonly used in clinic include photography and so on. Photographs can make part of the structure of the subject clearly displayed on X-ray film, and can be printed as objective records for long-term preservation. Special X-ray examinations, such as tomography, waveform recording and angiography, can also be performed if necessary. But X-ray screening is only one of the methods of clinical auxiliary diagnosis.

Industry

        In industry, X-ray screening is mainly used for X-ray detection of solid materials and products in film industry, also known as industrial radiography or radio graphic inspection (RT), which is a very effective method to find underground defects. X-ray detection can detect hidden holes and defects in various solid materials, including metals, plastics, composites, silicone resins and rubber. X-ray screening can be done by computer or digital radiography, and the inspector can adjust the contrast and expand more areas of interest. The generated digital image can be saved on CD-ROM, sent to customers by e-mail, and can be easily archived.

Safety inspection

        X-ray screening is also widely used in safety inspection. Safety inspectors, metal detectors and other equipment are developed on the basis of X-ray for safety inspection.

Conclusion

The above are two simple introductions to the use of X-ray security inspection machine, I hope to help you understand our products better.
