[en] In 1999 the International Atomic Energy Agency initiated a coordinated research program (CRP) with the aim to define a methodology for the implementation of the European QA/QC protocol for mammography in the Eastern European countries. In Hungary three mammography centers with dedicated mammography devices and film-screen systems have been selected for participation in the program. The outcome of mammography can be predicted by image quality evaluation on clinical and test phantom images and the patient doses. The improvement of these performance indicators after QA/QC program implementation should be an outcome of the project. The authors summarize the program of work, the activities and their preliminary results. (author)
