measurement. You can measure a maximum of eight groups of data.
The outcome will be displayed in the measurement result window, as
shown below.

Two-axis volume method can be used to perform volume measurement by
calculating only one set of measured data.
Operating Method:
The two-axis volume method is similar to the generic B mode Cir/Area
measurement ellipse method. You can measure a maximum of eight
groups of data.
3-Axis method
V= (π/6) × A × B × M,
(A: the length of major axis. B: the length of minor axis. M: the length of
the third axis.)
Three-axis method can be used to perform volume measurement by
calculating two sets of measured data, EA and the length of the third axis.
To complete volume measurement, first measure EA by ellipse method,
and then measure the length of the third axis with the distance
measurement method, and the value of volume will be displayed
automatically.
To measure volume:
In the B mode
1. Obtain a cross-section image and freeze the system.
2. Measure the lengths of the major axis and the minor axis of the cross
section with the ellipse method.
3. Unfreeze the system to acquire a new image (vertical-section image),
