Figure 3. The breast projection and volumetric measurement.

Figure 3

This figure shows the horizontal section of the breast in the top view. The gray part is the virtual chest wall simulated by computer to stand for the chest wall. Point N = the medial base of the nipple, N’ = the lateral base of the nipple, NP = the vertical distance from point N to the virtual chest wall and N’P’ = the vertical distance from point N’ to the chest wall. The mean value of NP and N’P’ was calculated as the projection of the breast. The space between the skin surface and the virtual chest wall was measured as the absolute volume of breast.
