Direkte Röntgenvergrößerung und normale Aufnahme.* Vergleichende Untersuchungen zur klinischen Abgrenzung (1. Teil)

Summary The outlining of fine details is examined in both non-screen films with direct Roentgen magnification and normal films. On the basis of theoretical and practical experiments it was found that the normal non-magnified Roentgen film is superior in so far as the fine structure is concerned in comparison with the direct Roentgen magnification. A direct magnification of non-screen films is not advisable.
