Purpose:
Experimental investigations of a new digital mammography system.
Materials And 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.
