Medical imaging uses various technologies to visualize the inside of the body without surgery. X-rays are a common form of medical imaging that uses ionizing radiation. X-rays are generated when high-speed electrons collide with a metal target in an x-ray tube. They can pass through tissues and be captured on the other side to form an image. While x-rays are low cost and can identify bones, they provide poor soft tissue contrast and carry radiation risks if overused. Protective equipment aims to minimize radiation exposure for patients and staff during x-ray exams.
