X-ray tube

An X-ray tube is a device that produces X-rays used in medical imaging. It works by rapidly heating a cathode (filament) to emit electrons, then accelerating these electrons toward a metal anode using a high voltage. When the electrons hit the anode, their energy produces X-rays, which pass through the body to create images of bones and tissues. The amount and focus of X-ray production are controlled to ensure clear images while minimizing exposure. Overall, the X-ray tube is a vital component that safely generates the radiation needed for diagnostic imaging.
