[Automatic dose-rate control during linear tomography (author's transl)].
Investigations on test grids, phantom-kidneys filled with contrast medium and a phantom skull in the case of linear tomography with various angles and constant, triangular or V shaped dose-rate function during tomograms showed that constant exposure over a certain angle of cut leads to minimum thickness. The V shaped distribution remains unregarded since it produces doublepictures. Radiographs exposed mainly in the middle projection give less contrast than those with constant dose rate and smaller planigraphic angles. Concentrating exposure on outer components leads to double pictures.
