How did doctors look inside the body at the Hospital?
Without lifting a knife, doctors looking at the body today can see the tiniest cracks in bones, tell whether a tumour is malignant or benign, even identify certain chemicals in the brain.
This is all possible with cameras and computer screens. This new perspective on the inside of the body started with the discovery of X-rays.
They were discovered on November 8, 1895, quite by chance, by the German physicist Wilhelm Röntgen. He called them X-rays because he neither knew what they were nor understood their properties. Scientists now know they are electromagnetic waves, like light and radio waves, but with a shorter wavelength. see hospital health
