The quantification of mammographic density using Fuzzy C-means (FCM) segmentation method. a Original MLO mammogram. b Four FCM-clusters indicated by different colors. The cluster #1 is air and defines the anterior breast boundary. c A dividing point P on the breast-chest wall boundary is marked by the operator. d The breast-chest wall boundary is found after gradient tracing and b-spline curve fitting. e Three FCM-clusters are classified within the breast. The cluster #1 (red color) is fat, and cluster #2 and #3 represent dense tissues. f The breast area and dense tissue area is measured to calculate the percent density
