X-rays are a form of high-energy electromagnetic radiation that passes through soft tissue while being absorbed by denser material such as bone, making them the basis of medical radiography. They were discovered on 8 November 1895 by the German physicist Wilhelm Conrad Roentgen, who produced the first X-ray medical image, of his wife hand, within weeks of the finding and provisionally named the radiation after the mathematical symbol for an unknown quantity.

Cancer, Conditions

X-ray imaging is foundational to cancer diagnosis and staging, and ionizing radiation itself became a cancer treatment, radiotherapy, within years of Rontgen's 1895 discovery.

Rontgen's 1895 discovery of X-rays rapidly became indispensable to orthopedic diagnosis of fractures and skeletal deformities.

Radiology, Medical Specialties

Radiology began with Wilhelm Conrad Rontgen's 1895 discovery of X-rays.

Tuberculosis, Conditions

Chest radiography became central to tuberculosis diagnosis and to twentieth-century mass screening campaigns.
