Register: neutral / scientific
Definition
A form of electromagnetic radiation used to see inside the body or inside objects, especially in medical and security settings.
Extended Meaning
“X-ray” refers to both the radiation itself and the image produced by it.
It is used to examine bones, teeth, lungs, luggage at airports, and internal structures in science and engineering.
As a verb, “to X-ray” means to take an X-ray image of something or someone.
Detailed Explanation
X-rays pass through soft tissues but are absorbed by denser materials like bones or metal. This creates contrast in images, allowing doctors and technicians to diagnose fractures, infections, dental problems, and other health issues.
Outside medicine, X-rays help inspect machines, detect cracks in metal, review luggage security, and study the internal structure of materials.
The image produced by an X-ray is often called an “X-ray scan” or “X-ray image.”
Semantic Field
X-ray vs. scan — a scan may be MRI or CT; an X-ray uses radiation.
X-ray vs. ultrasound — ultrasound uses sound waves.
X-ray vs. CT — CT uses multiple X-rays to create 3D images.
X-ray vs. photograph — a photograph shows surfaces; an X-ray shows interiors.
X-ray vs. radiation — X-ray is a type of radiation.
