Photograph showing an early method for testing x-rays, Europe
An early method of testing the output of X-rays using a fluoroscope is shown in this photograph. The body could be viewed through a fluoroscope without taking or developing time-consuming X-ray photographs. The X-rays instead fell on a screen which fluoresced immediately. This let the physician see the same thing as an X-ray photograph, or in this case use the fluoroscope to test the X-ray output. X-rays were discovered in 1895 by German physicist Wilhelm Röntgen (1845-1923). Battlefield surgeons and medics quickly took them up. However, X-ray departments were rare in hospitals in the UK until the 1930s. This was because of the costs and the need for trained personnel. Early X-rays also took time to develop. The images were sometimes poor quality.
