Experimental investigations of image quality in X-ray mammography with a conventional screen film system (SFS) and a new full-field digital mammography unit (DR) with a-Se-detector.
OBJECTIVE
Determination of image quality of a new digital mammography system with an a-Se-detector.


METHODS
Radiograms of the Wisconsin Mammographic Random Phantom, Modell 152 A (Radiation Measurements Inc., Wisconsin) were acquired using a conventional film screen and a digital system.


RESULTS
With the conventional film screen system there were detected 191/a 38.2 and with the digital mammography 219/a 43.8 of 225 possible details.


CONCLUSIONS
Based on these results there is the possibility to replace the conventional film screen system by the digital mammography with a-Se-detector--this has to be confirmed in further clinical trials.
