[Evaluating computerized tomography and other procedures]

In computed tomography (CT) an object is scanned with X-rays from different angles. The digitally recorded data of the absorption values or profiles are used in a mathematical algorithm to reconstruct an image, which is then converted into an gray-scale image for reproduction. CT imaging replaces various modalities that give less sufficient information. It is safe, without risk, painless, faster and more cost efficient. CT reduces costs by 30 to 50%; the amount of cost reduction can be verified.
