5.1 Functional description
Similar to computer tomography or magnetic res-
onance tomography, sectional images can be
generated with CBCT. With CBCT, an X-ray tube
and an imaging sensor opposite it rotate around
a seated or standing patient. The X-ray tube
rotates through 180°-540° and emits a conical X-
ray beam. The X-rays pass through the region
under investigation and are measured for image
generation by a detector as an attenuated grey
scale X-ray image. Here, a large series of two-
dimensional individual images is acquired during
the revolution of the X-ray tube. Using a mathe-
matical calculation on the rotating image series
via a reconstruction computer, a grey value coor-
dinate image is generated in the three spatial
dimensions. This three-dimensional coordinate
model corresponds to a volume graphic that is
made up of individual voxels. This volume can be
used to generate sectional images (tomograms)
in all spatial dimensions as well as 3D views.
