Volume Method
▶
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)
▶
3 Distance x Factor: The volume value is calculated using three diameters from the longitudinal
plane and transversal pla
ne and a factor (F) value entered by a user. ( A x B x C x F)
▶
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)
▶
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)
