When Konrad R¨ontgen discovered the “X-rays” in 1895 in W¨urzburg, Germany,
he opened a window to non-invasive insight into the human body. The attenuation
of X-rays is strongly dependent on the tissue through which they travel,
for example, bone attenuates more than fat. The thus produced shadow images
deliver visual information about the interior of the body. The disadvantage is
that dense tissue like bones masks the tissue along the same path of the Xrays,
whence the application was restricted to those parts of the body with few
bones. Examinations of the brain were, due to the surrounding skull, virtually
impossible without the dangerous addition of contrast agents.
The conceptual and technical breakthrough was achieved in the sixties: Nobel
laureates Allan Cormack and Godfrey Hounsfield suggested an imaging system,
where shadow images of an imaginary cross section through the body and
for many directions are registered simultaneously. Each of these shadow images
contributes only little information. The exploitation of the fact that all of these
images cover the same part of the body allowed for images of the interior of the
body with previously unknown resolution. This was the starting point of a long
success story.

Konrad Rontgen discovered when the "X-rays" in 1895 in Würzburg, Germany,
He opened a non-invasive Insight Into Window to the Human Body. The attenuation
of X-rays is strongly dependent on the tissue Through which they travel,
for example, Bone attenuates more than FAT. Thus the images produced Shadow
Deliver Visual information About the Interior of the Body. The disadvantage is
that dense tissue like Bones masks the tissue along the path of the Same Xrays,
WHENCE the Application was restricted to those with few Parts of the Body
Bones. Examinations were of the Brain, Surrounding Due to the Skull, virtually
Impossible Without the addition of contrast agents Dangerous.
The Technical and conceptual breakthrough was achieved in the sixties: Nobel
Laureates Allan Cormack and Godfrey Hounsfield SUGGESTED an Imaging System,
where images of an imaginary cross section Shadow Through the Body and
Directions for MANY are Registered simultaneously. Each of these images Shadow
contributes Little information only. The Exploitation of the Fact that all of these
images Cover the Same Part of the Body of images allowed for the Interior of the
Body with previously Unknown resolution. This was the Starting Point of a long
Success Story.
