The type of radiation used in medical imaging to view the body is typically X-rays. X-rays are a form of ionizing radiation that can penetrate tissues and provide images of internal structures. They are commonly used to diagnose fractures, infections, and other conditions. In addition to X-rays, other imaging techniques like CT scans and MRIs use different forms of radiation, but X-rays remain a foundational tool in medical diagnostics due to their efficiency and effectiveness.
