Adapted from Reference [28]. Technique for finding the lateral border line of fatty breasts. a, b With the probe pressed, the lateral border line is obscured because the dorsal fat and breast fat look similar in shape. c, d When the inner pressure of the probe is released, the adipose layer of the retro-mammary space, LAFS (dotted arrow), slides, and only the fat in the breast (arrow) is displaced outward. Then, a curve (yellow line) from the outer boundary of LAFS (asterisk) appears. Repeat (b) and (d) several times
