説明

We examined in the simultaneous photography of mamma with low voltage magnification and contact. The minute focus X-ray tube for low valtage, the photographying bed and the film slide were made for this purpose. The sensitizing paper which only has the back was used for the magnifying photograpey and nonscreen for the contact photography. The magnifying power of three to four times is actually useful and greater power than this can never find any minute substanes. The magnifying photography showed the excellent results that the scattered rays decreased due to the Groedol efficiency, and minute lime precipitated images and fibrous index images were found which cannot be recognized by the contact photography.
