Maccia, X. Nadeau, R. Renaud, S. Castellano, P. Schaffer, R. Wahl, P. Haehnel, G. Dale, B. Gairard] This paper describes the methodology followed for the implementation of a Quality Control (QC) programme for 53 mammography installations used within the context of the breast cancer screening campaign in the Bas-Rhin region of eastern France. In order to demonstrate the efficacy of such a programme, the most relevant results of QC tests and procedures related to each element of the imaging radiological chain are presented and compared for five control visits carried out at six months' interval over a period of two and a half years. A reduction of about 50% (from 15.2 mGy to 8.5 mGy) of breast entrance doses (normalised to a breast thickness of 4.5 cm) and a significant improvement of spatial resolution at high contrast are reported.
