Volume Method
X
3 Distance: The volume value is calculated using three diameters in the longitudinal and
transverse planes. (4 / 3 x 3.14 x A x B x C / 8)
X
3 Distance x Factor: The volume value is calculated using three diameters from the longitudinal
plane and transversal plane and a factor (F) value entered by a user. ( A x B x C x F)
X
Ellipsoid: The volume value is calculated using the lengths of the Main axis and the beside axis.
(4 / 3 x 3.14 x Main / 2 x (Beside / 2)
Λ
2)
X
Sum of 20 Disks: The volume value is calculated by summing the areas in the 20-parallel planes.
(d / 20 x (A1 + A2 + ... A20), d : the sum of distances between disks)
NOTE: 3 Distances: A = 1

The default factor value (F) is ‘0.5’. If it is changed, a value between 0 and 100 (0 < factor <= 100) is
recommended.
