[Computer tomography--present role and future prospects (author's transl)].

Abstract

The actual CT apparatus requirements connot be estimated at present. For cranial CT, one apparatus for every 200,000 inhabitants is considered necessary. For radiotherapy, apparatus with a slow scanning rate will be sufficient. A scanning time below 1 second is required for cardiac investigations. More attention should be paid to the kinetics of organ-specific contrast media, so that better diagnostic information may become possible by effecting the roentgenograms at the most favorable time.
