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.
III
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.

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".
Supported application measurement categories:
z Abdomen z Obstetric z Cardiology z Gynecology z Vascular z Urology z Small Parts z Orthopedics (ORTH) z Emergency (EM) z Nerve

1.3 Measurement, Calculation and Study
There are three kinds of measurement items.
Measurement
Results of measurements are directly obtained via the measurement tools, which are indicated by “ ”.E.g. "Distance" in the 2D general measurement, or "HC" in the OB measurement.
Calculation
Results of calculations are automatically derived by the system, using other measured or calculated values as parameters, they are indicated by “ ”. E.g. EFW (Estimated Fetal Weight) in the OB measurement.
If all measurement tools related to a calculation tool are completed, the system will automatically complete the calculation result. If some measurement tools are performed again, the system will automatically update the calculation result using the latest measurement results.
Overview 1-4
Study
A group of measurements and / or calculations for a specific clinical application. E.g. AFI in the OB measurement.
Fold/ unfold the study to hide/show the measurement or calculation items included.
1.4 Measure 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 in green, and a fixed caliper appears in white.
Symbols of the 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 indentify different measurements.
NOTE: You can preset the cursor type in [System Preset] -> [Application], see "2.2 Measurement
Parameters" for more information.
1.5 Result Window
Two types of result windows are used to display results numerically or graphically.
1.5.1 Result Display
Set [Result] to "ON" and the latest results display in the result window.
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 display in the result window, and a maximum of 2 graphical result windows can appear in the screen.
To indentify 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
To move the result window,
1-5 Overview
1. Place the cursor to the result window title and press <Set>.
2. Rotate the trackball to place the result window in a desired position.
3. Press the <Set> key to fix the result window.

A general measurement result can be assigned to an application measurement item in the result window.
System-defined Application Item Assignment
The procedures are as follows:
1. Move the cursor to a general measurement result in the result window, press <Set> when the item highlighted in green, the matching list pops up as shown below.
Matching application items that meet the following requirements are displayed:
a) Preset in current application package.
b) Use the same general measurement tool with the result.
Application items in the Abdomen 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 an application measure menu (e.g. Abdomen), when a general measurement
(e.g. "Distance") is completed.
2. Click the desired application item in the menu. The selected application item also has to meet the matching rules in step 1.
3. If the application item(s) is/are preset 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.
Overview 1-6
a) Type in the new name.
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
Press <Esc> in the keyboard, or select [Cancel] in the matching list to exit.

2.3.1 Obstetric Formulae
The obstetric formulae are used in GA, EFW calculations and Fetal Growth Curve.
GA and FG Formulae
GA will be automatically calculated after the corresponding measurements are completed. The system will recalculate the GA after new measurements are completed.
Tips: 1. For preset of the default formula, See "2.3.2 Obstetric Preset Operations".
2. For more information about GA and Fetal Growth Curve, see "5 Obstetrics".
GA and FG formulae are shown in table below:

Fetal Weight Formula
EFW is a calculation item. If all tools required for EFW formula have been performed, EFW will be obtained automatically. The system will recalculate the EFW after new measurements are completed.
2-5 Preset
Tips: Formulae of EFW and EAF2 of GA/ FG are different from those in the [Fetal Weight]
page.
EFW formulae of GA/ FG are used to perform the GA calculation or the Fetal Growth
Curve based on EFW.
EFW formulae in the [Fetal Growth] page are used in EFW calculation based on
some OB measure results (e.g. AC).
The Fetal Weight formulae are shown in the following table:

Weight Percentile for Age
The Clinical Percentile (CP) and Ultrasound Percentile (UP) will be calculated and displayed in the report in the following format according to the formula selected for EFW calculation.
z CP(Calc Method)(Formula) ××%: Where Calc Method may be LMP, PRV, IVF, BBT, and
EDD;
z UP(Calc Method)(Formula) ××%: Where Calc Method may be AUA, CUA.
Wherein the Formula can be preset in [Setup]-> [System Preset]-> [OB]-> [Fetal Weight]-> [EFW-GP].
E.g. CP (LMP)(Hadlock) 73.4%.
Preset 2-6
Clinical Percentile (CP)
Find the average value and the threshold in the formula (to calculate EFW) in the FG table according to the clinical GA (obtained in patient information such as LMP, IVF).
If the actual EFW value is in the following range, keep calculating; otherwise, the CP will not be displayed.
Average EFW x1.25 > EFW > Average EFW x0.75
E.g. EFW-GP(LMP) is EFW Clinical Percentile calculated from the LMP obtained from the patient information.
Ultrasound Percentile (UP)
It has the same calculation method with CP except to use the ultrasound GA instead of clinical GA.
Eg. EFW-GP(AUA) and EFW-GP(CUA) is EFW Clinical Percentile calculated from the AUA and CUA respectively.
