EXPERINENTAL STUDIES ON INFLUENCE WHICH X-RAY TUBE VOLTAGE EXERT UPON THE APPEARANCE OF THE SHADOW OF PHTHISIS CAVITY

Abstract

We changed the voltage of X-ray tube according to conditions of potients. Especially, we made experiments to show up shadows of cavities. We obtained satisfactory results. Therefore it reports the practical facts and comparison between the conditions of shadows of cavities obtained by the radiographing and the clinical conditions.
