[Experimental investigations at the new digital mammographic system].
OBJECTIVE
Experimental investigations of a new digital mammography system.


METHODS
The digital mammography system SenoScan (Fischer Imaging) is based on 4 charged coupled devices (CCD) (slot detector). The pixel size is 50 micro m, field of view 21 x 29 cm (2), effective quantum efficiency (DQE) (0) 50 %, spatial resolution 10 lp/mm, and memory depth 12 bit. The object of investigation was the Wisconsin Mammographic Random Phantom, Model 152 A (Radiation Measurements Inc., Wisconsin). The radiograms were acquired using the digital mammography system.


RESULTS
The digital mammography detected 225 of 225 possible details. The surface dose was 6.95 mGy.


CONCLUSIONS
These experimental results support the use of the digital mammography in practice. This has to be confirmed in further clinical trials.
