title: [Characteristics of manifestations of border effect in electroroentgenobronchography].
abstract: Specificity of the image reflecting the outlines of the bronchial lumena on the electroroentgenograms is explained by the manifestation of the border effect. The latter is caused by the non-uniformity of the electric field over the surface of the selenium layer with a regular distribution of charges. With electroroentgenography of sharply contrasted objects in a little contrast medium the potential relief has highly pronounced differences, this leading to distorsion of the dimensions and the shape of the objects under examination. When interpreting electroroentgenograms these specific features should be taken into consideration. In constructing improved medical radiographic equipment it will be advisable to envisage the possibility of controlling the said effect.
