Security
X-ray detectors play a crucial role in security inspection in multiple aspects:
Baggage Screening at airports and train stations to identify potentially dangerous or prohibited items;
Cargo & Vehicle Inspection to ensure that goods being transported do not contain illegal or hazardous substances;
Customs Inspection to identify undeclared items or items that violate trade regulation.
Baggage Inspection
At airports or railway stations, screeners use an X-ray inspection system to check passengers’ baggage for prohibited goods such as dangerous materials, capable of ensuring transport safety while maintaining high throughput efficiency.
Parcel Inspection
At parcel delivery hubs of logistic centers, millions of parcels are scanned every day through X-ray inspection systems to identify prohibited stuff such as explosives, toxic and corrosive substances.
Cargo & Vehicle Inspection
At ports, airports, a cargo & vehicle inspection system can be used to scan containers, trucks and other types of vehicles to detect contraband and smuggled goods.
Highway Fast Track Inspection
To enforce the policy in favor of delivering fresh produce fast and at little or no cost on the highway, highway authorities uses X-ray inspection system to check cargo vehicles carrying fresh produce at the fast track, capable of identifying the cargo types efficiently.
Security Inspection for Public Event
In the case of major events such as Olympic Games, international submit, X-ray inspection system is essential for safety inspection to keep dangerous goods away from the crowd.
Body Check
An X-ray inspection system can be used to scan persons at customs, borders, prisons and other places for narcotics, explosives, weapons, gems or other prohibited or dangerous goods.
Industrial
X-ray detectors have numerous applications in the industrial sector:
Quality Control and Inspection: X-ray detectors are used to inspect the integrity and quality of products;
Electronic Manufacturing: X-ray detectors are employed to inspect the internal structure of electronic devices such as circuit boards;
Material Analysis: X-ray detectors help determine the composition and microstructure of alloys;
Nondestructive Testing: X-ray detectors can inspect pipelines, turbine blades, and other critical components are inspected for hidden defects without causing damage to the equipment.
Food Inspection
X-ray imaging technology can be used to check a variety of food, such as seafood, vegetables, meet and grain, for foreign objects including glass fragments, stone debris, metal chips and ossified bone, with the advantages of high efficiency and high precision.
Ore Sorting
An ore sorting system utilizes X-ray transmission for ore grading and automatically removes low-grade ores by gas injection technology. It is helpful in extending the lifespan of mining operations and increasing the total value of the deposit, thereby significantly improving energy efficiency and cost-effectiveness. It is mainly applied for tungsten ore, manganese ore, coal, talc, rough diamonds, rare earth elements, iron ore, etc.
Resource Recovery
Compared with conventional recovery method in which it is hard to tell metal debris of similar colors from each other, X-ray imaging technology can identify every fragment, and is widely used in recovery of fragments of magnesium, aluminium, stainless steel and circuit board,as well as furnace slag.
Conveyor Belt Inspection
X-ray imaging can be used in coal mine to inspect a conveyor belt with steel wire rope core in operation. When an abnormality occurs to the steel wire rope, such as broken threads, split or rusted rope, or fall-off of rubber layer or joint twitching, it can be monitored and diagnosed in real time to prevent a catastrophic accident such as broken rope.
Non-destructive Testing
Based on the fact that various materials are different in absorption of X-ray, the difference in absorptive capability results in differentiated images. It can be widely used in detection of foreign objects in tire, drug, timber, shoe and garment as well as in the fields of IC fabrication, electronic fabrication, automobile industry, lithium battery manufacture, etc.
Industrial CT
Industrial CT helps to obtain cross sectional images of an object being scanned and their dimensions are measured accurately. Therefore, internal faults that cannot be spotted from the outside can be identified through the images formed. Also, the density, formation and distribution of the object inspected can be observed clearly.
Medical
X-ray detectors have several important applications in the medical field:
Radiography: X-ray detectors capture the radiation that passes through the body to produce images that help doctors diagnose conditions like fractures, pneumonia, or abnormalities in the lungs and other organs;
Computed Tomography (CT) scan: multiple X-ray detectors rotate around the patient, collect data from different angles and create detailed cross-sectional images of the body;
Dental Imaging: X-ray detectors are used for taking intraoral X-rays to detect cavities, assess the health of the jawbone, and plan dental implants or orthodontic treatments.
Dental Imaging
In dentistry, X-ray detectors are used for taking intraoral X-rays to detect cavities, assess the health of the jawbone, and plan dental implants or orthodontic treatments. It includes panoramic X-ray, Intraoral X-ray, cone beam computed tomography. dental imaging plays a vital role in ensuring effective and personalized dental care, improving treatment outcomes and patient well-being.
Computer Tomography (CT)
A medical imaging technique that provides detailed cross-sectional images of the body works by using a rotating X-ray source and a series of detectors to capture multiple X-ray projections from different angles around the patient. These projections are then processed to reconstruct detailed 2D or 3D images of the internal structures of the body, which can help detect abnormalities, such as identifying tumors, cysts, bleeding, fractures and infections in various organs.
Computed Radiography (CR)
CR is a medical imaging technique. In CR, an imaging plate is exposed to X-rays and captures the latent image. This plate is then processed in a reader device that converts the latent image into a digital signal. Digital images can be easily stored, transmitted, manipulated, and analyzed. This enables better image quality control, easier comparison of images over time for follow-up studies, and the ability to apply various image processing techniques to enhance the visibility of specific details.
Scientific
X-ray detectors have wide-ranging applications in scientific research:
Crystallography: X-ray detectors are crucial in determining the crystal structure of materials by scientists to study the atomic arrangement in substances, which helps understand the properties and behavior of materials;
Materials Science: Researchers use X-ray detectors to analyze the microstructure and phase composition of materials;
Biological Research: X-ray detectors are employed to determine the three-dimensional structure of proteins and other biomolecules. This provides insights into their functions and interactions, aiding in drug design and understanding biological processes.
Astrophysics: X-ray detectors on satellites and telescopes are used to study X-ray emissions from celestial objects such as black holes, neutron stars, and active galactic nuclei.
X-Ray Fluorescence (XRF)
This powerful analytical technique used to determine the elemental composition of a sample works based on the principle that when a sample is exposed to high-energy X-rays, the atoms in the sample are excited and emit characteristic fluorescent X-rays at specific wavelengths. By measuring the intensities and wavelengths of these emitted X-rays, it's possible to identify and quantify the elements present in the sample.
X-Ray Diffraction (XRD)
In XRD capable of studying the crystal structure of materials, when a beam of X-rays interacts with a crystalline material, the X-rays are scattered by the regularly arranged atoms in the crystal lattice. These scattered X-rays interfere with each other, creating a diffraction pattern. The positions, intensities, and shapes of the diffraction peaks in this pattern provide valuable information about the crystal structure.
