General
CT stands for computer tomography and uses X-rays, just like conventional X-ray technology. The CT scan is an examination in which the inside of the human body is imaged in 3D.
The X-ray beam passes through the human body in a thin axial slice, and this is repeated in various directions (fig. 12).
