Computed tomography 2D




Computed tomography with a fan beam (fan beam tomography). Though this, one-dimensional images (lines) are created on the detector (s. Sinogram) which deliver a two-dimensional data set in the reconstruction.

By recording several tomograms with different heights, a three-dimensional data set can be created from the individual images. This means that, in addition to the rotation around the sample axis, movement in the height of the sample is also possible. This recording process therefore usually takes longer than 3D computer tomography but, at the same time, uses less scattered radiation, leading to a higher quality result.
