by calculating 3 sets of distance data, L, W, and H. Measure the three
pieces of data in the method of B mode generic distance measurement,
and then 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 length and the width.
3. Unfreeze the system to acquire a new image (vertical-section image),
and then freeze it.
4. Measure the height. You can measure a maximum of one group of data.
The outcome will be displayed in the measurement result window.
In the 2B mode or 4B mode
1. Obtain the cross-section image and the vertical-section image.
2. Measure the length and the width.
3. Roll the trackball to the next image, vertical section image, measure the
height. The outcome will be displayed in the measurement result window,
as shown below.
4. Press Measure to finish and exit.

Ratio To determine the ratio, take two measurements: A and B. The system
calculates the ratio: A/B or B/A.
To measure ratio:
1. Press Measure to activate measurement function.
2. Roll the trackball to highlight Ratio, press Set to activate a
measurement cursor on the screen.

4. Measure the second distance B, move the cursor and press Set to
anchor the start point, and the mark "+" appears. Move the cursor
with trackball, Measurement Results displays the real time
measurement value and calculation result.
5. During measurement, you can press Change once to change the
settled point and the active point; if you press Change a second time,
the system interchanges the numerator and denominator.
6. Roll the trackball and press Set to complete the measurement, and the
calculation result will be displayed in the measurement result window.
7. Roll the trackball and press Set to begin a new ratio measurement.
You can measure a maximum of four groups of data. The outcome
will be displayed in the measurement result window.
8. Press Measure to finish and exit.

% Stenosis Distance stenosis
To determine the distance stenosis, take two distance measurements: A
and B. The system calculates the stenosis:
To measure distance stenosis:
1. Press Measure to activate measurement function.
2. Roll the trackball to highlight % Stenosis, and select Distance, and
then press Set to activate a measurement cursor on the screen.
3. Measure the first distance with the distance measurement method.
4. Measure the second distance, move the cursor and press Set to anchor
the start point, and the mark "+" appears. Move the cursor with
trackball, Measurement Results displays the real time measurement
