X-Ray

X-Ray, also known as radiography technology, is a technique that uses high-frequency electromagnetic waves to penetrate materials and visualize their internal structures. It is widely used in medicine, industry, security systems, and scientific research. X-ray radiation was discovered by Wilhelm Conrad Röntgen in 1895 and has since revolutionized numerous fields.

Working Principle

X-ray systems emit high-energy photons that pass through objects. Areas with lower density, such as soft tissues or materials, allow the rays to pass through, while high-density regions absorb them. This creates a contrasted image of the internal structure on a detector or film.

Applications

Medical Applications

• Bone fractures and orthopedic diagnostics
• Dental and jaw radiography
• Lung examinations
• Detection of tumors and internal organ abnormalities

Industrial Applications

• Weld seam inspection (NDT)
• Detection of internal voids in composite materials
• Analysis of cracks and defects within components
• Quality control in aerospace, automotive, and defense manufacturing processes

Security and Defense

• Airport baggage screening systems
• Cargo and vehicle inspection systems
• Detection of contraband and weapons at border checkpoints

Advantages

• Enables non-destructive imaging of internal structures
• Fast and results-oriented
• Applicable to a wide range of materials
• Cost-effective and capable of producing repeatable results

Disadvantages

• Presents health risks due to ionizing radiation
• Requires lead aprons, shielding, and restricted access areas
• Limited penetration through very thick or dense materials
• Low resolution for some soft tissues

X-Ray Technology in Türkiye

In Türkiye, X-ray systems are widely used in the healthcare sector. Domestic solutions for security and defense applications have also been developed by institutions such as HAVELSAN, ASELSAN, TÜBİTAK MAM, and STM. Additionally, locally produced X-ray scanners are employed in customs facilities for civil aviation and border security applications.
