Jul 19, 2024 · The discovery of X-rays – a form of invisible radiation that can pass through objects, including human tissue – revolutionised science and medicine in the late 19th century. Wilhelm Conrad Röntgen (1845-1923), a German scientist, discovered X-rays or Röntgen rays in November 1895.

Oct 24, 2024 · X-rays were discovered in 1895 by German physicist Wilhelm Konrad Röntgen while investigating the effects of electron beams (then called cathode rays) in electrical discharges through low-pressure gases.
X-rays were originally noticed in science as a type of unidentified radiation emanating from discharge tubes by experimenters investigating cathode rays produced by such tubes, which are energetic electron beams that were first observed in 1869.

X-rays are capable of penetrating some thickness of matter. Medical x-rays are produced by letting a stream of fast electronscome to a sudden stop at a metal plate; it is believed that x-rays emitted by the Sun or stars also come from fast electrons. The images produced by x-rays are due to the different absorption rates of different tissues. Calci...
On 8 Nov 1895, Wilhelm Conrad Röntgen (accidentally) discovered an image cast from his cathode ray generator, projected far beyond the possible range of the cathode rays(now known as an electron beam). Further investigation showed that the rays were generated at the point of contact of the cathode ray beam on the interior of the vacuum tube, that t...
William Coolidge invented the X-ray tube popularly called the Coolidge tube. His invention revolutionized the generation of X-rays and is the model upon which all X-ray tubes for medical applications are based.
A breakthrough in tungsten applications was made by W. D. Coolidge in 1903. Coolidge succeeded in preparing a ductile tungsten wire by doping tungsten oxide before reduction. The resulting metal powder was pressed, sintered and forged to thin rods. A Very thin wire was then drawn from these rods. This was the beginning of tungsten powder metallurgy...
A computed tomography scan or CAT-scan uses x-rays to create images of the body. However, a radiograph (x-ray) and a CAT-scan show different types of information. An x-ray is a two-dimensional picture and a CAT-scan is three-dimensional. By imaging and looking at several three-dimensional slices of a body (like slices of bread) a doctor could not o...

Feb 18, 2020 · Today we call his invention the fluoroscope. In 1913, William Coolidge invented the Coolidge vacuum tube. These tubes create continuous X-ray emissions, are more stable than the cathode ray tubes, and allow the intensity and energy of the rays to be controlled separately.
Sep 17, 2015 · Wilhelm Roentgen, Professor of Physics in Wurzburg, Bavaria, discovered X-rays in 1895—accidentally—while testing whether cathode rays could pass through glass. His cathode tube was covered in heavy black paper, so he was surprised when an incandescent green light nevertheless escaped and projected onto a nearby fluorescent screen.
Sep 21, 2023 · The scientific and medical communities will forever be indebted to an accidental discovery made by German physicist Wilhelm Conrad Röntgen in 1895. Röntgen originally set out to research the electrical charges or cathode rays created in vacuum tubes known as Crookes tubes.
