Principles of CT scan

Principle

X-ray computed tomography consists of using X-rays that are converted to a digital signal by a detector and computational algorithms to calculate virtual sections through an object without the need to physically cut them. With this data it is possible to generate 3D representations of the sample under investigation. Both from the external as from the interior of the sample.
