[A method of digital processing of bronchograms]

Digital bronchogram processing is described as a new method in roentgenology. The aim of this method is to improve the visibility of the single morphological detail inside the bronchi lumens and to make the image of the contrast bronchi more easily and clearly seen. It will ease the procedure of measuring the diameters of the respiratory ways and will help to get more accurate datum of bronchi lumens in cases with chronic bronchitis. Digitization results in improving visibility of the single morphological changes in the bronchi lumens and makes the controls of the contrast bronchi more clear and distinct, in this way it helps greatly in measuring diameters of bronchi. Ordinary bronchograms, bronchosonograms, bronchotomograms, and coherent-optical bronchograms were taken as comparison reference information. According to the investigated parameters, digital processing outdoes the above mentioned x-ray methods of investigation.
