摘要：
Purpose: Determination of image quality of a new digital mammography system with an a-Se-detector. Material and Method: 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. Conclusion: 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.
