[Experimental study on image quality when using screens in mammography (author's transl)].
1. Different type of screens and x-ray films have been investigated using a Kodak mamma-phantom I.T.O. 745 and compared with conventional non screen industrial film radiography. 2. Dosisreduction by using screens depends on the used film/screen system. It is possible to reach a relation of 1 : 10. 3. The information depends on type of screen and of type of film. Therefore, it is possible to reach the information of non screen industrial film radiographs. 4. A suitable film/screen system allows without loss of any diagnostic information to replace non screen industrial films needing a high exposure dosis by a film/screen system needing decreases dosis.
