Figure 3

This figure shows the testing scores, that is, Dice coefficient ranged [0, 100], for four FCN networks during the courses of training. Using the test dataset (N = 58 exams, that is, 116 MLO and CC view mammograms) we tested each network every 100 iterations of training. The plots include the Dice coefficient values for the training dataset (N = 455 exams, that is, 910 MLO and CC view mammograms). FCN networks for breast areas quickly converges to 98–99 after 1000 iterations for both the training and testing datasets. FCNs for dense areas relatively slow to converge compared to FCNs for breast areas, with the maximum Dice score for 94–95 after 4000 or 6000 iterations for both the training and testing datasets. We used the version of FCNs for breast areas at iteration 4000, and the version of FCNs for dense areas at iteration 8000 for this study.
