An X-ray is a type of high-energy radiation that can pass through the human body. It is used to create images of the inside of the body, and can be used to diagnose and treat medical conditions.
X-rays are made up of electromagnetic waves, which are a type of energy that travels through the air at the speed of light. When these waves strike an object, they cause it to emit X-rays. These X-rays then travel through the body and are absorbed by different tissues in different amounts. The amount of absorption depends on the density of the tissue; denser tissues absorb more X-rays than less dense tissues.
Once the X-rays have passed through the body, they are detected by an X-ray machine. This machine converts the X-rays into electrical signals, which are then converted into images by a computer. The resulting images show the structure and function of different parts of the body.
X-rays are a valuable tool for diagnosing and treating medical conditions. They can be used to examine bones for fractures or other abnormalities, to look for foreign objects in soft tissues, or to assess organs for signs of disease. Additionally, X-rays can be used to guide procedures such as biopsies or surgeries.
