Using the penetration ability of X-rays, hard foreign bodies such as bones, plastics and various metal foreign bodies can be detected more sensitively and stably, helping you to improve the quality of finished products more effectively. Not only can foreign matters in foods (such as various meat products, aquatic products, fruits and vegetables, additives, milk powder, chocolate, etc.) be detected, including metals, glass, ceramics, stones, bones, plastics, etc.; Can also identify product defects, such as packaging cracks, bubbles, content defects, etc.; Complete finished product inspection is realized. Widely used in food industry, medicine industry, textile industry, integrated circuit board and other industries. Quality control in the food industry meets HACCP and IFS certification requirements to identify product defects, such as product breakage, product deformation or product missing, and eliminate potential product quality hazards. With the development of food X-ray machines and the continuous improvement of living standards, the quality and safety of people’s food and daily industrial products have higher requirements. The state has also formulated strict safety inspection regulations and laws accordingly. In order to better meet the relevant requirements and improve the detection level, the food X-ray machine has also developed from the original single-view detection technology to the new multi-view detection technology, so as to provide more choices for customers with different needs.
(1) x-ray diagnosis
The application of X-ray in medical diagnosis is mainly based on X-ray penetration, differential absorption, photosensitization and fluorescence. As X-rays pass through the human body, they are absorbed to different degrees. For example, the amount of X-rays absorbed by bones is more than that absorbed by muscles, so the amount of X-rays passing through the human body is different. This carries information on the density distribution of various parts of the human body, and the intensity of fluorescence or photosensitivity caused on the fluorescent screen or photographic film is quite different. Therefore, shadows of different densities will be displayed on the fluorescent screen or photographic film (after development and fixation). According to the contrast of shade, combined with clinical manifestations, laboratory results and pathological diagnosis, it can be judged whether a certain part of the human body is normal. Therefore, X-ray diagnosis technology has become the earliest non-invasive visceral examination technology in the world.
(2) X-ray therapy
The application of X-ray in treatment mainly depends on its biological effect. When X-ray with different energies is applied to irradiate the cell tissue of the focus part of human body, the irradiated cell tissue can be destroyed or inhibited, thus achieving the purpose of treating certain diseases, especially tumors.
(3) X-ray protection
At the same time of using X-rays, people have discovered the problems that lead to radiation injuries such as alopecia of patients, skin burns, visual impairment of staff, leukemia, etc. In order to prevent the injury of X-rays to human body, corresponding protective measures must be taken. These constitute the three major links of X-ray application in medicine-diagnosis, treatment and protection.
Security check application
X-ray machines are widely used in safety inspection of railway stations and airports.
The X-ray safety inspection equipment is completed by feeding the checked luggage into the track-type passage by means of a conveyor belt. After luggage enters the channel, it will block the light barrier signal, and the detection signal will be sent to the control unit, triggering the radiation source to emit X-ray beam. A very narrow fan-shaped X-ray beam passing through the collimator penetrates the luggage on the conveyor belt and falls onto the dual-energy detector. The high-efficiency semiconductor detector converts the received X-rays into electrical signals. These very weak current signals are directly quantized and transmitted to the industrial control computer through the universal serial bus for further processing. After complicated operation and imaging processing, high-quality images are obtained.
