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.
In 1999, Time placed Shoe-Store X Rays on a list of the 100 worst ideas of the 20th century. [29] [30] A shoe-fitting fluoroscope appeared on a 2011 episode of the History series American Restoration. [31] Its radionuclide source was found to be so dangerous that it was removed and replaced with a static X-ray. [32]
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
From initial therapeutic experiments, a new field of x-ray therapy was born, referred to as röntgenotherapy after Wilhelm Röntgen, the discoverer of x-rays. It was still unclear how the x-rays acted on the skin; however, it was generally agreed upon that the area affected was killed and either discharged or absorbed. [17]
The radioactive gamma rays are emitted through the body as the natural decaying process of these isotopes takes place. The emissions of the gamma rays are captured by detectors that surround the body. This essentially means that the human is now the source of the radioactivity, rather than the medical imaging devices such as X-ray or CT.

Kassabian invented a positioning device for chest X-rays that displayed the roundness of the ribs; previously, X-ray images had rendered them as flat. [12] In 1907, he reported his attempts to take X-rays of infants' hearts. The heart could not be seen on X-rays at that time, so Kassabian injected patients with a contrast agent, bismuth ...
