Linear-distance measurements.

<p>XZ plane and YZ plane intersected the body surface at each landmarks of body surface to form the red lines. The landmark points for measuring were identified by the intersections of red lines. The horizontal red lines indicate the level of the sternal notch, the upper margin of nipple base, the nipple, the lower margin of nipple base and the inframammary fold. The vertical lines indicate the anterior midline and the middle line of the nipple. Point A = SN (sternal notch), A’ = the superior margin of the nipple base, AA’ = SN-N, B’ = the medial margin of the nipple base, BB’ = N-MD (midline), C’ = the inferior margin of the nipple base, C = the lowest point of the inframammary fold, CC’ = N-IMF (inframammary fold), D = the intersection of the midline and the level of the inframammary fold, AD = SN-LIMF (level of inframammary fold).
