A History of X-Ray

A Brief History of XRay

Wlhelm Conrad Roentgen received Nobel Prize in 1901

Steps in the Development of XRay

1913 – William David Coolidge invents thermionic emission tube

1937 – First practical rotating anode tubes were manufactured

1971 – Computed Tomography (CT) scanning was introduced into medical practice by Godfrey Hounsfield who developed the technology at EMI central research laboratories.

Pioneers in the Development of XRay

Sir William Morgan (1785) was the first man to produce x-rays.

Michael Faraday (1821) – conducted his first experiments on electrical discharge in a partially evacuated glass vessel.  He discovered that the ‘voltaic arc’ was accompanied by the florescence of gas– he called ‘radiant matter’.

Julius Plucker  (1850) – First to observe Green Glass Flouresence in partially evacuated discharge tubes.

Wilhelm Hittorf (1870) – discovered florescent discharge, he termed ‘cathode rays’.

Henri Becquerell, a French scientist working along the same lines as Roentgen, discovered a natural radiation source in 1896.

Philipp Lenard proposed ‘inverse square law’.

Joseph John Thomson discovered electron – 1896

1906 – Charles Barkla discovered that x-rays could be scattered by gases

 In 1913, William David Coolidge revolutionized the field of radiology by inventing what is now referred to as the Coolidge X-ray tube.
