(1) The measured area is A
(2) The distance between the two ventral part electrodes is 10 cm.
(3) Assuming abdomen is circle, the radius is W/2π. Therefore A is calculated as A=10*(W/π).
(4) We calculated B (visceral fat area ratio in A from CT). We compensated for the approximate value of visceral fat area in the measured area by multiplying. This can be expressed as:
V/A =V/(B*10*WC/3.14), where π is 3.14.
