The use of additional filtration through 3 mm aluminium enables significant reduction of the radiation dose in xeromammography with the Senographe, compared with conventional xerography, by a factor of 2-3, and, compared with film not requiring an intensifying screen, by a factor of 10-12. The applied tissue doses are between 0.14 and 0.30 rad per exposure. Hence, the radiogenic carcinoma risk, which is still largely hypothetic, is very low as far as this mammographic system is concerned. The high quality of the mammographs guarantees absolute diagnostic safety. |
