Trace Method
To measure Circumference / Area:
1. Press Measure to activate measurement function.
2. Roll the trackball to highlight Cir/Area. Then select Trace, and
press Set to activate a measurement cursor on the screen.
3. Roll the trackball and press Set to anchor the start point.
4. Roll the trackball to outline the region of interest. As you move the
trackball, the system displays dots to outline the structure. To correct
an error in the trace, press Back to move in reverse along the traced
outline. Roll the trackball to move forward again. The system
automatically closes the loop when the last measurement marker is
moved very near to the start point. Or press Set to close the loop. The
system draws a line from the position of the active measurement
marker to the beginning of the loop.
5. Roll the trackball and press Set to begin a new circumference/area
measurement. You can measure a maximum of four groups of data.
The outcome will be displayed in the measurement result window, as
shown below.
6. Press Measure to finish and exit.
2-Axis volume method
V= (π/6) × A × B
2
, (A: the length of major axis. B: the length of minor
axis)
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 four groups
of data.
3-Axis method
V= (π/6) × A × B × M,
