ANALYSIS OF THE RESULTS OF A QC PROJECT ON MAMMOGRAPHY IN GREECE

Quality Control (QC) has been carried out on twenty nine mammographic units installed in public hospitals, all over Greece. The QC procedure includes: registration of general information and technical descripti on of the mammographic chain, QC checks concerning environmental condi tions, radiation safety, beam characteristics, accessories and periphe rals performance, as well as image quality and patient dose. The colle cted data are characterised by great non-uniformity and in some cases indicate a poor performance level. Analysis of the results helps to im prove the existing situation with reference to patient dose and image quality.
