Symbol Description
Caution!
3. Safety Precautions
Please observe the following precautions to ensure patient and operator’s safety when using this
system.
CAUTION: 1. Select the proper patient image and measurement tools. Only
the professionals can decide the appropriate measurements
and results.
2. Confine measurement calipers to the actual Region of Interest
(ROI). Measurements that extend beyond the ROI will be
incorrect.
3. Before examining a new patient, it is necessary to press the <
End Exam> key to end the current scan and delete the patient
information and data. Otherwise, new patient data will be
combined with the previous patient.
4. When the system is turned OFF or the < End Exam> key is
pressed, all the data that have not been saved are lost.
5. Changing modes during a measurement will delete the General
Measurement data.
6. Pressing the < Freeze> key to unfreeze the image during a
measurement will clear the General Measurement data.
7. Pressing the < Measure> key during a measurement will clear
the General Measurement data.

IV
8. Pressing the < Clear> key will clear the measurement caliper,
all data in the result window, comments and body mark.
9. In dual-B imaging mode, the measurement results of the
merged image can be inaccurate. Therefore, the results are
provided for reference only, not for confirming a diagnosis.
10. Quality of the extended image constructed in iScape
(panoramic imaging) dependents on the skill of operator. Extra
attention should be paid during the iScape measurement since
the results could be inaccurate.
11. Ensure that measurement data correctly corresponds to the
fetus during the Obstetric Measurement.
12. Fully understand the functionality of this system by referring to
the Operator’s Manual - Basic Volume.
13. When the result of auto trace doesn’t match the image exactly,
please make the measurement manually.

1.2.2 Measurement Tool
There are two kinds of measurement tools.
General tools: Basic measurement tools in General Measurement, such as the "distance" and
"Area".
Application tools: The measurement tools in Application Measurement. These items are
classified and combined in clinical application package such as Abdomen, Obstetric, etc. E.g.
HC (head circumference) in the Obstetric measurement is one of the application tools.
Tips: 1. Actually, most application tools use the general measurement method while
measuring, e.g. an "Area" tool is used when measuring the HC. Only the
application measurement results are recorded in the report.
2. For definition of the measurement, calculation and study, refer to "1.3
Measurement, Calculation and Study".
To Active the Measurement Tool
The procedures are as follows:
1. Select the tool:
zMove the cursor to the item on the menu and press <Set>.
zTouch an item on the touch screen.
2. Perform the measurement according to the actual situation.
3. After finishing the measurement, perform operations if necessary.

measurement.
On the touch screen, measurement tools are displayed using square button as .
Calculation
Results of calculations are automatically derived by the system, using other measured or
calculated values as parameters, they are indicated by “ ” in preset screen. E.g. EFW (Estimated
Fetal Weight) in the OB measurement.
If all measurements related to a calculation tool are completed, the system will automatically
calculate the result. If some measurement tools are performed again, the system will automatically
update the calculation result using the latest measurement results.
On the touch screen, calculation tools are displayed using square button as .
Study

by “ ” in preset screen. E.g. AFI in the OB measurement.
Fold/ unfold the study to hide/show the measurement or calculation items included.
On the touch screen, study items are displayed as , with an arrow indicating the tools to
be selected.

1-6 Overview
1.4 Measurement Caliper
A measurement caliper is a graphics consists of several points and straight line or curve drawn on
the ultrasound image.
Fixed/ Active End
The ends of calipers can be active or fixed. The active end is called a Cursor.
Caliper Color
An active caliper appears green while a fixed one appears white in the system default preset.
Symbols of Caliper Ends
8 symbols are used as the caliper ends circularly, as shown in figure below.
These symbols display in calipers as well as in the result window to identify different
measurements.
NOTE: You can preset the cursor type and color in [System Preset] -> [Application], see "2.2
Measurement Parameters Preset" for more information.
1.5 Result Window
Measurement window displays the conducted measurement’s result and the engaging measurement in
real time.
1.5.1 Result Display
Select [Show Result] on the touch screen and the latest results display in result window in time
sequence.
When viewing the results:
If the result window is full, the oldest value will be replaced according to the "first in, first out"
rule.
A maximum of 8 results can display in result window, and a maximum of 2 graphical result
windows can display in the screen.
To identify the measurement results, symbols or numbers are used in the numerical result
window while "No:1" or "No:2" is used in the graphical result window.
The results can display in the following type:
No result displays when a measurement item/tool is activated but without the start point fixed.
The result displays as numbers when the value obtained is within the clinical range.
The result displays as "?" when it is out of the ultrasonic range.
1.5.2 Moving Result Window

1. Place the cursor on the result window title and press <Set>.
2. Rotate the trackball to place the result window in a desired position.
3. Press <Set> to fix the result window.

Overview 1-7
1.5.3 Result Window Assignment
An application measurement result can be assigned to a general measurement item from the
result window. The application item can be an existing item in system or a new user-defined one.
Assigning an Existing Application Item
The procedures are as follows:
1. Move the cursor to a general measurement value in the result window; press <Set> when the
item is highlighted in green, the matching list pops up as shown below.
Matching application items that meet the following requirements are displayed:
hContained in current application package.
hUse the same general measurement tool with the result.
Application items in the Obstetric measurement that use the "Distance" method are listed
as shown above.
2. Select an application item in the list, press <Set>.
3. The assigned value displays in the result window and is saved in the exam report.
Tips: You can perform an assignment directly to the latest general measurement result by:
1. Enter the application measurement menu (e.g. Obstetric), when a general
measurement (e.g. "Area") is completed.
2. Click the desired application item (e.g. HC) in the menu (or touch screen). The
selected application item also has to meet the matching rules in step 1.
3. If the application item(s) is/are included in the current report, the assignment results
will be saved in the report.
Assigning a New Application Item
When no (desired) item displays in the matching list, you can create a new application item. The
procedures are as follows:
1. Select [new] at the bottom of the matching list.
2. The following dialog box pops up.
a) Type in the new name.

1-8 Overview
b) Select the application region.
3. Click [OK] to assign the general result to the new item.
NOTE: Re-assignment for the assigned general result is not available.
Exiting Result Assignment
