    Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.

    en.wikipedia.org/wiki/History_of_computed_tomography

    The history of X-ray computed tomography (CT) dates back to at least 1917 with the mathematical theory of the Radon transform. [ 1 ] [ 2 ] In the early 1900s an Italian radiologist named Alessandro Vallebona invented tomography (named "stratigrafia") which used radiographic film to see a single slice of the body.

  4. History of radiation therapy - Wikipedia

    X-ray experiments in pulmonary tuberculosis proved useless. Aside from the medical profession losing faith in the ability of x-ray therapy, the public increasingly viewed it as a dangerous type of treatment. This resulted in a period of pessimism about the use of x-rays, which lasted from about 1905 to 1910 or 1912. [21]

    Today, we celebrate the 129th anniversary of the discovery of X-rays. X-rays were first discovered on November 8, 1895. In 1996, Indore became the first city worldwide to celebrate this milestone, by under supervision Dr OP tiwari and Radiology team by Shivakant vajpai, Maan singh choudhary and marking the centenary of this groundbreaking discovery.

    Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.

    Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.
