Principle

The CT principle is demonstrated with the aid of simple objects. In the case of very simple targets, only a few images need to be taken in order to achieve a good result. The more complicated the objects are, the more images are necessary in order to show all the details. In addition, special samples are used to demonstrate how artefacts are generated and what causes beam hardening.

Benefits


Very fast, direct image capture

Easy to understand linear procedure does not require training, instant results

Integrates smoothly with software used in medical diagnostics to use additional CT software features

All objects can be captured since object is inserted gravity-independently


Tasks


Record a CT scan of the simple objects. While doing so, vary the number of steps.

Record a CT scan of the metal samples and analyse the result in view of beam hardening.
