I studied a direct magnified roentogenograph and its clinical application since 1954. Conclusions are as follows : 1) I make a new modeled tube (reconstructed Toshiba made 6kw tube) with bias phenomen Cput a certain resistance between the filament line and the line of the metal surrounding of the filament) for magnified roentogenograph. 2) The greatness of the focus is 0.24mm by 0.24mm. 3) Sharpness of the magnified roentogenograph is much better than that of taken by routine one. 4) I take a magnified tomogram of a fantom, and a. quality of a picture is excellent. 5) The focus of this tube often shows a roughness, so it has to use with care. 6) The magnified roentogenograph is well demonstrated pulmonary markings in the peripheral segment of the lung. 7) The magnified roentogenograph shows fine structures in an exsudative consolidation of the lung. 8) The magnified roentogenograph demonstrates much more various findings in a productive consolidation of the lung than that of routine picture. 9) The magnified roentogenograph shows perfectly a character of the wall, content and a draining bronchus of the pulmonal cavity. 10) The magnified roentogenograph reveals minute calcified foci in the pulmonal field. 11) The magnified roentogenogram of the chest of children gives nice contrast of pulmonal markings and the hilar density, it is useful to differentiate pathologic changes from normal anomalies in the lung field. 12) Bronchiogram is taken by magnifying method demonstrates finer view of the bronchial cast than that of routine bronchiogram. 13) The magnified tomogram is able to demonstrates a cavity of the lung than that of of general one.
