“…Current techniques to determine volumes locally are water displacement, girth, and caliper measurements, MRI imaging, X-ray tomography, ultrasound, and three dimensional imaging. 21,[31][32][33][34] The distance between girth measurements on a limb determines the length of the segment that is used in the calculation of geometric volume. This segment length has not been standardized, 18 and varies from 1 cm, 6 3 cm, 27,35-37 4 cm, 6,20,25,28,[38][39][40][41][42][43] 5 cm 44 to 10 cm and more and in between.…”
