Where are the main applications of x-ray foreign body detectors?
Using the penetrating power of X-rays, from bones, plastics and other hard foreign objects to various metal foreign objects can be detected with higher sensitivity and stability, helping you to more effectively improve the quality of finished products. Not only can detect foreign objects in food (such as various meat products, aquatic products, fruits and vegetables, additives, milk powder, chocolate, etc.), including metals, glass, ceramics, stones, bones, plastics, etc.; it can also identify product defects , Such as packaging cracks, bubbles, content defects, etc.; to achieve complete product inspection. It is widely used in food industry, pharmaceutical industry, textile industry, integrated circuit board and other industries. The quality control of the food industry meets the requirements of HACCP and IFS certification to identify product defects, such as product damage, product deformation or product missing, etc., and eliminate product quality risks. The development of X-ray machine x ray machine for baggage With the continuous improvement of living standards, people have higher requirements on the quality and safety of food and daily industrial products, and the country has accordingly formulated strict safety inspection regulations and regulations. In order to better meet related needs and improve the detection level, food X-ray machines have also developed from the original single-view inspection technology to a new multi-view inspection technology, so as to provide more choices for customers with different needs.
(1) X-ray diagnosis
X-ray security scanners are used in medical diagnosis, mainly based on the penetration, differential absorption, photosensitivity and fluorescence effects of the x-ray security scanner. Since X-rays are absorbed in different degrees when passing through the human body, for example, bones absorb more X-rays than muscles, so the amount of X-rays after passing through the human body is different, so that the density distribution of various parts of the human body is portable Information, the intensity of the fluorescence or sensitization caused on the fluorescent screen or on the photographic film is quite different, so the fluorescent screen or on the photographic film (after developing and fixing) will show shadows of different densities. According to the contrast of shades, combined with clinical manifestations, laboratory results and pathological diagnosis, it can be judged whether a certain part of the human body is normal. Thus, X-ray diagnostic technology has become the world's first non-traumatic visceral inspection technology.
(2) X-ray treatment
X-ray security scanner is used in treatment. It is mainly based on its biological effect. When X-rays of different energies are used to irradiate the cells and tissues of the human lesions, the irradiated cells and tissues can be destroyed or inhibited, thereby To achieve the purpose of treatment of certain diseases, especially tumors.
(3) X-ray protection
While using the x ray security scanner, people have discovered problems that cause hair loss, skin burns, visual impairment of the staff, leukemia and other radiation damage. To prevent the x ray security scanner from harming the human body Injury, corresponding protective measures must be taken. The above constitutes the three major links of X-ray application in medicine-diagnosis, treatment and protection.
Security check application
X-ray machine x ray machine for baggage is widely used in security inspection of railway stations and airports, etc.
The x ray security scanner is accomplished by transporting the checked baggage into the crawler channel by means of a conveyor belt. After baggage enters the aisle, the light barrier signal will be blocked, and the detection signal will be sent to the control unit to trigger the ray source to emit X-ray beams. A very narrow fan-shaped X-ray beam passing through the collimator penetrates the luggage items on the conveyor belt and falls on the dual-energy detector. The high-efficiency semiconductor detector converts the received X-rays into electrical signals. These very weak current signals It is directly quantified and transmitted to the industrial control computer through the universal serial bus for further processing. After complex calculations and imaging processing, high-quality images are obtained.
