Steps taken to generate a 3-D volume-rendered breast model. 2A, Entire scan field of view consisting of both breasts and torso anatomy; 2B, A coarse segmentation to isolate the breast region of interest; 2C, More precise trimming to remove the chest wall and other non-breast tissue from each individual slice; 2D, Surrounding air image removed from the previous image; 2E, View of the breast slice image after subtracting air image in 2D from image in 2C. A final trimming is performed to complete the breast segmentation from the rest of the patient’s anatomy. 2F, the final 3-D view of the breast model completed for volume measurement analysis.
