Dual-Energy Computed Tomography

ByBernhard Schmidt, Cynthia McCollough

In 1895, Wilhelm Conrad Röntgen discovered X-rays when

performing measurements with a cathode ray tube.

Accidentally, he noticed that these rays – till then unknown –

were able to pass though matter. Immediately, the benefit

for medical care was clear – the ability to look into the

human body without a dangerous surgery.
