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.
Some 2 dozen known X-ray sources were monitored—some for more than 100 days—and a number of new X-ray transients were discovered. The Diffuse X-ray Spectrometer (DXS) STS-54 package was flown as an attached payload in January, 1993 to obtain spectra of the diffuse soft X-ray background. DXS obtained the first-ever high resolution spectra of ...
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.

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.

Rollins suggested in 1901 that anyone working with X-rays should wear leaded glasses, enclose the X-ray tube in a leaded box and to cover all areas of the body not being radiographed with a radiopaque shield. He published a series of over 200 articles warning of the possible dangers of the X-ray beam. For many years his suggestions were ignored ...
The history of X-ray microscopy can be traced back to the early 20th century. After the German physicist Röntgen discovered X-rays in 1895, scientists soon illuminated an object using an X-ray point source and captured the shadow images of the object with a resolution of several micrometers. [2]
He opened the first x-ray laboratory in the United States in Chicago, and had completed over 1400 x-ray examinations by 1896. His work was critical to the history of radiation protection. [citation needed] He was the father of Arthur Wolfram Fuchs (1895 - 1962), the inventor of the fixed kilovoltage technique of radiography.
