[Methodology of digital processing of bronchograms].
A new roentgenologic method for the digital processing of bronchograms and bronchozonograms is described. It has several advantages compared with methods from coherent optics. It provides improved sharpness and contour visibility of the contrasted bronchi and their details by shading correction and alternative positive or negative display mode and therefore improved image quality compared with conventional bronchograms and bronchozonograms. The accuracy of measurements of bronchial lumina and the evaluation of bronchial patency is significantly improved.
