Abstract

The standard test object used to assess the imaging performance of digital mammography systems in Europe is the CDMAM model 3.4. The recently released CDMAM model 4.0 differs from the model 3.4 in the layout, number and range of thicknesses of gold contrast details used to assess threshold contrast detail detection. In order to evaluate CDMAM 4.0 we compared its performance with that of the CDMAM 3.4 using several digital mammography systems at various dose levels. We also assessed the reproducibility of the results compared to that of the previous model. CDMAM 4.0 results were comparable to results for CDMAM 3.4 for detail diameters in the range 0.1 to 0.5mm and for the larger detail diameters there were increased differences as would be expected due to the design differences of the CDMAM 4.0. The reproducibility of CDMAM 4.0 results was found to be better than that of CDMAM 3.4 results.
