Summary

Recent developments in total body computerized tomography result in shortening of the time and amount of radiation, avoiding artefacts caused by patient's movement and exact definition of the slice by topograms. In comparison to conventional X-ray-tomograms there are further informations concerning especially the retromaxillar region and the neck by better differentiation of the density of soft tissue. The possibility of storage and easy reproduction of the tomograms is important for interdisciplinary treatment of neoplasms.
