Paper Abstract
We have previously developed a breast boundary detection method by using a gradient-based method to search for
the breast boundary (GBB). In this study, we developed a new dynamic multiple thresholding based breast boundary
detection system (MTBB). The initial breast boundary (MTBB-Initial) is obtained based on the analysis of multiple
thresholds on the image. The final breast boundary (MTBB-Final) is obtained based on the initial breast boundary and
the gradient information from horizontal and the vertical Sobel filtering. In this way, it is possible to accurately segment
the breast area from the background region. The accuracy of the breast boundary detection algorithm was evaluated by
comparison with an experienced radiologist's manual segmentation using three performance metrics: the Hausdorff
distance (HDist), the average minimum Euclidean distance (AMinDist), and the area overlap (AOM). It was found
that 68%, 85%, and 90% of images have HDist errors less than 6 mm for GBB, MTBB-Initial, and MTBB-Final,
respectively. Ninety-five percent, 96%, and 97% of the images have AMinDist errors less than 1.5 mm for GBB,
MTBB-Initial, and MTBB-Final, respectively. Ninety-six percent, 97%, and 99% of the images have AOM values
larger than 0.9 for GBB, MTBB-Initial, and MTBB-Final, respectively. It was found that the performance of the
proposed method was improved in comparison to our previous method.
