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.
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.

Eddy Clifford Jerman (November 21, 1865 – September 13, 1936) was an American inventor and an early expert in the techniques of medical radiography.In the years that followed the discovery of X-rays, Jerman was one of the first people to focus on the details that created quality X-ray images, such as exposure and positioning.
The Radio Corporation of America (RCA) leads the music format with 45 RPM records, later to conquer the market for cheap players. The first publication in Germany in this format appears 1953rd; The British physicist Dennis Gabor (1900–1979) invents holography. This method of recording and reproducing image with coherent light allows three ...
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.
1896 Wilhelm Conrad Röntgen discovers the X-rays while studying electrons in plasma; scattering X-rays—that were considered as 'waves' of high-energy electromagnetic radiation—Arthur Compton will be able to demonstrate in 1922 the 'particle' aspect of electromagnetic radiation.
