Fetal Weight Formulae
EFW is a calculation item. If all tools required for the EFW formula have been performed, EFW will be obtained automatically. The system will recalculate the EFW after new measurements are completed.
Tip: Formulae of EFW and EFW2 of GA/FG are different from those on the [Fetal Calc] page ([Setup]->[System Preset]->[OB] page).
EFW formulae of GA/FG are used to perform the GA calculation or the Fetal Growth
Curve based on EFW.
EFW formulae on the [Fetal Growth] page are used in the EFW calculation based on certain OB measurement results (e.g., AC).
The Fetal Weight formulae are shown in the following table:

DOC and EDD.
UP (Calc Method) (Formula) ××.××%: Where Calc Method may be AUA, CUA.
Clinical Percentile (CP)
Find the average value and calculate the threshold range 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. If not, the CP will not be displayed. average EFW x1.25 > EFW > average EFW x0.75
E.g. EFW-GP(LMP) is the EFW Clinical Percentile calculated from the LMP obtained from the patient information.
Ultrasound Percentile (UP)
This has the same calculation method as CP except for using the ultrasound GA instead of clinical GA.
E.g. EFW-GP(AUA) and EFW-GP(CUA) is the EFW Clinical Percentile calculated from the
AUA and CUA respectively.

5.3 GA
5.3.1 Clinical GA
The GA (Gestational Age) and EDD (Estimated Delivery Date) are calculated according to clinical parameters.
1. Click [Info] on the touch screen and register the patient information in the [Patient Info]
→
[OB] dialog box.
The system automatically calculates the GA and EDD after entering the relative information.
The calculation methods are listed as follows:
LMP: enter the LMP, the system will calculate the GA and EDD.
DOC: enter the DOC, the system will calculate the GA and EDD.
IVF: after you enter IVF, the system will calculate the GA and EDD.
PRV: enter the date and GA of the last exam, the system will calculate a new GA and
EDD.
BBT: after you enter BBT, the system will calculate the GA and EDD.
EDD: enter the EDD, the system will calculate the GA and LMP.
2. The clinical GA is shown at the top of the obstetric report.
Tip: The latest EDD and GA calculation is considered as the final value if more than one
EDD and GA calculations are valid.
5.3.2 Ultrasound GA
The ultrasound GA and ultrasound EDD are calculated according to the parameters obtained in the measurements.
GA in OB Items
AUA (Average Ultrasound Age)
CUA (Composite Ultrasound Age)
GA in OB Items
The GA in the OB items is calculated from the related GA tables/formulae. It is independent from the clinical GA.
1. You can preset the GA formulae and whether to display the EDD or not in [System Preset]
→
[OB]. See “2.3 Obstetric Preset” for details.
2. The GA and other measurement values display in the results window after a measurement.
If the Diagnostic GA exceeds the threshold, an OOR (out of range) displays in the results window and this result is not recorded in the report.
3. The GA of an OB item displays to the right of the item measurements.
5-2 Obstetrics
4. For result values used to calculate GA (Gestational Age) and EDD (Estimated Date of
Delivery), the formula used in this calculation can be selected from [Formula].
AUA
AUA is the average of the valid GAs that are calculated according to the biparietal diameter (BPD), head circumference (HC), abdomen circumference (AC), femur length (FL), Gestational Sac (GS), crown rump length (CRL), etc.
1. All valid values of all the above items will be included in the AUA calculation in the system default method.
2. Click the checkboxes to the right of the related items to select whether to include the item in the AUA calculation or not. The AUA value varies according to the selection.
CUA
The CUA is calculated according to formulae based on certain measurement items (the items involved include the biparietal diameter (BPD), head circumference (HC), abdomen circumference
(AC) and femur length (FL)). To calculate the CUA, all the GA formulae of the parameters involved must be Hadlock, the unit of the parameters is cm and unit of CUA is week. The formulae are listed as follows:
1. CUA(BPD) = 9.54+1.482*BPD+0.1676*BPD 2
2. CUA(HC) = 8.96+0.540*HC+0.0003*HC 3
3. CUA(AC) = 8.14+0.753*AC+0.0036*AC 2
4. CUA(FL) = 10.35+2.460*FL+0.170*FL 2
5. CUA(BPD, HC) = 10.32+0.009*HC 2 +1.3200*BPD+0.00012*HC 3
6. CUA(BPD, AC) = 9.57+0.524*AC+0.1220*BPD 2
7. CUA(BPD, FL) = 10.50+0.197*BPD*FL+0.9500*FL+0.7300*BPD
8. CUA(HC, AC) = 10.31+0.012*HC 2 +0.3850*AC
9. CUA(HC, FL) = 11.19+0.070*HC*FL+0.2630*HC
10. CUA(AC, FL) =10.47+0.442*AC+0.3140*FL 2 - 0.0121*FL 3
11. CUA(BPD, HC, AC) = 10.58+0.005*HC2 +0.3635*AC+ 0.02864*BPD*AC
12. CUA(BPD, HC, FL) = 11.38+0.070*HC*FL+0.9800*BPD
13. CUA(BPD, AC, FL) = 10.61+0.175*BPD*FL+0.2970*AC+0.7100*FL
14. CUA(HC, AC, FL) = 10.33+0.031*HC*FL+0.3610*HC+0.0298*AC*FL
15. CUA(BPD, HC, AC, FL)=10.85+0.060*HC*FL+0.6700*BPD+0.1680*AC
The default method of calculating the CUA is to use the formula that involves more measurement items. You can also select the parameters by clicking the checkboxes to the right of the related items.
OB Growth Percentile
The obstetric growth percentile is used to estimate the fetal growth. It calculates the difference between the ultrasound measurement results and the measurement results corresponding to the clinical GA in the FG table. The percentile will not be calculated when there is no clinical GA, or no
FG table, or the SD Type of the FG table is set to “None.”
The premise is: data in the FG table are (approximately) normally distributed and support “lowerlimit < average value < upper-limit.”
Obstetrics 5-3
The system does not calculate the OB growth percentile if:
An FG table is not normally distributed.
There is no upper/lower deviation set in the FG table.
The FG table has the upper/lower deviation set, but certain clinical GA values have no upper/lower deviation or the deviation value is not plus. The fetal growth curve is not affected.
E.g. Jeanty FG table of RAD.
The OB growth percentile is displayed in the results window, the measurement report, the exported
PDF report and the OB structured report, and it supports print viewing and printing.
5-4 Obstetrics
5.4 Obstetric Measurement Tools
The system supports the following 2D/M/Doppler obstetric measurements.
NOTE: 1. The measurement tools mentioned below are configured in the system. The application measurement packages provided in this system are generally different combinations of measurement tools. For more information about package preset,
see “2.4.2.2 Application Measurement Preset.”
2. The Smart NT must be used with convex-wide probe and good image quality. If an evident inaccurate recognition exists, confirm the target profile manually and adjust the result.
3. If the results of the calculation items of CI, FL/BPD, FL/AC, HC/AC and FL/HC exceed the clinical range, the result value displays as “value*.”

1. Enter the patient's basic information and obstetric information in the [Patient Info]
→
[OB] dialog box.
2. Perform one or more GA related parameter tools.
3. Under report status, touch [Compare Bar] on the touch screen to bring up the following figure.
Obstetrics 5-17
Select the [Print] checkbox to determine whether to include the bar in the printed report or not.
5.7.3 Z-Score
As the FL, BPD and GA are most relevant to the fetus cardiac structure and the Z-Score regression equation is related to the natural logarithm value of the FL, BPD and GA variables, the
Z-Score of cardiac structures can be obtained by looking at the Z-Score table, which is important in fetus cardiac growth evaluation and intrauterine interventional therapy.
In (predicted cardiac dimension) = m*In(FL, GA or BPD)+c
Z-Score = (In(actual)-In(predicted cardiac dimension))/root MSE
Where the unit of FL and BPD is cm, GA is week, m is multiplier, c is intercept and root MSE is root-mean-square error, which can be obtained from the table.
1. Enter the patient's basic information and obstetric information in the [Patient Info]
→
[OB] dialog box.
2. Measure the BPD and FL.
3. Select Z-Score parameters (with Z-Score tag in the name) from the measurement menu.
4. Open the report to check the Z-Score result.
Tip: the Z-Score study is effective for fetuses aged 15~40 weeks.
5.7.4 Fetal Growth Curve
The fetus growth curve compares the measured data of the fetus with the normal growth curve to judge whether the fetus is in normal growth state. The growth curve data is sourced from the Fetal
Growth Table.
1. Enter patient information and obstetric information in [Patient Info]
→
[OB] dialog box.
2. Perform one or more fetal growth parameter tools.
3. Touch [Trend] on the report touch screen to display the Obstetric Growth Curve dialog box.
The dialog box displays the growth curve and the position of the measurement value.
5-18 Obstetrics
Two drop-down lists above the curve display the measurement item/tool and the formula of the curve, which can be changed.
Different symbols are used on the growth curves to identify measurement data of different fetuses.
Current and historic data of a fetus are displayed in the same symbols, with the historic data appearing in smaller symbols.
Click the [Print] checkbox to determine whether to include the growth curve in the printed report or not.
The green dotted line indicates the clinical GA on the X-axis.
Select the number and layout of the curves from [Display Layout].
1*1: one curve displays in the screen.
2*1: two curves (up/down) display in the screen.
2*2: four curves display in the screen.
Click [Previous]/[Next] to turn the growth curve pages.
4. Click [Save] to confirm the setting and exit the page.
Tip: If the patient ID is blank, the clinical GA is not calculated or the measurement value is not valid, the measurement values will not be displayed on the curve.

6.1 Cardiac Exam Preparations
Make the following preparations before measuring:
1. Confirm that the current probe is appropriate.
2. Check that the current system date is correct.
3. Click [Info] on the touch screen and enter the patient information on the [Patient Info]
→
[CARD] page.
For more details, see “Exam Preparation
→
Patient Information” in the Operator's Manual
[Basic Volume].
4. Switch to the correct exam mode.
6.2 Basic Cardiac Measurement Procedures
1. Click [Info] on the touch screen and enter the patient information on the [Patient Info]
→
[CARD] page.
2. Press <Measure> to enter the Application Measurement.
3. Select the measurement tool from the menu or the touch screen to start the measurement.

6.3 Cardiac Measurement Tools
The system supports the following cardiac measurements:
NOTE: 1. The measurement tools mentioned below are configured in the system. The application measurement packages provided in this system are generally different combinations of measurement tools. For more information about
package preset, see “2.4.2.2 Application Measurement Preset.”
2. The heartbeat of the traced spectrum in VTI measurement should be equal to
that preset, otherwise the obtained HR (Heart Rate) will be incorrect. See “2.2
Measurement Parameters Preset” for the relevant preset.

6.4.3.13 Z Score
Z Score indicates the standard deviation of the individually measured value against the mean value. Referenced pediatric cardiac value is corrected by the height, weight, and body surface. Z
Scores that is standardly transformed is used to evaluate the cardiac measurement values, to define the distribution of the measurement result of an individual pediatric among those of the healthy pediatrics.
The Z-Score study is effective for pediatrics aged under 18 years old.
Formula:
Z-Score = (measured actual value - population mean value)/population standard deviation
Operating procedures:
1. Input the DOB (age), weight, and height in the <Patient> [CARD];
2. Select Z-Score related items in the measurement menu for performing measurement.
3. Check the Z-Score result in the <Report> page.

7.4 Vascular Measurement Operations
Tip: 1.
See the table in “7.3 Vascular Measurement Tools” above for measurement tools
and methods.
2.
For the definitions of measurement, calculation and study, see “1.3 Measurement,
Calculation and Study.”
3.
The order of the measurement items can be preset. See “2.4.2 Application
Measurement Preset” for details.
4. A measurement tool can be activated by clicking the item in the measurement menu or on the touch screen. It is described as “Select/Click ... in the measurement menu” in the following procedures.
5. The measurements of some tools described in this chapter are to be performed in several imaging modes. Select the appropriate imaging mode during measurement.
7.4.1 Measurement Tool Operations
1. Select the item/tool in the measurement menu.
2. Perform the measurement referring to the methods in the table above.
7.4.2 Calculation Tool Operations
Stenosis D
Function: measures the Normal Diam. and Resid. Diam., calculates the Stenosis D.
1. Select [Stenosis D] in the measurement menu or the touch screen.
2. Use the Distance measurement method in 2D General Measurements to measure the
Normal(D) and Resid(D).
Vascular 7-21
The Stenosis D is calculated automatically.
Stenosis A
Function: measures the Normal Area and Resid. Area, calculates the Stenosis A.
1. Select [Stenosis A] in the measurement menu or the touch screen.
2. Use the Area measurement method in 2D General Measurements to measure the Normal(A) and Resid(A).
The Stenosis A is calculated automatically.
ICA/CCA (PS)
Function: measures the flow velocity ratio between ICA and CCA to calculate the stenosis.
1. Select [ICA/CCA (PS)] in the measurement menu or the touch screen.
2. Measure the PS value of the ICA and CCA using the 2 PT method in D trace, and the system calculates the stenosis. Where, the ICA value adopts the maximum PS value of proximal, middle and distal and the CCA adopts the latest measured value after changing the
Prox./Mid./Dist. attribute (the default CCA adopts the distal PS value).
7.4.3 Study Tool Operations
IMT
NOTE: 1. The IMT function is unavailable on the product not configured with IMT.
2. The IMT measurement is available on frozen (or history) linear array images only.
Function: IMT (Intima-Media Thickness) measures the distance between LI (Lumen-Intima) and
MA (Media-Adventia).
The IMT values at 4 positions: CCA (Common Carotid Artery), ICA (Internal Carotid Artery), ECA
(External Carotid Artery) and Bulb (Bulbillate) need to be measured here.
1. Enter the IMT exam mode, scan and freeze the image (or review a historic image).
2. Select [IMT] in the measurement menu and enter the IMT measurement.
3. Select the side (Left/Right), angle and vessel wall (Near/Far).
4. Select an item such as [ICC, IMT], and the ROI box displays on the screen.
It appears as when Near is selected
Tip
It appears as when Far is selected
Make sure that you select the correct vessel wall (Near/Far) before the IMT measurement. Otherwise the intima may be recognized incorrectly due to different algorithms that are applied in near/far wall recognition.
5. Move the ROI box to the desired position, then press <Set>. Two auto trace lines appear in the box.
While the ROI box is green, you can:
Adjust the size of the ROI box.
Trace manually a) Move the cursor to a trace line. The trace line turns yellow. Press <Set>. b) Move the cursor along the interface of the vessel. Press <Set> to confirm the trace after re-adjusting.
Erase the trace lines inside the box by pressing <Clear>. (Long press <Clear> to clear all measurement calipers on the screen.)
7-22 Vascular
6. Press <Set> outside the box to confirm the adjustment result after the manual trace is complete. The results are recorded in the IMT report.
The system calculates:
IMT Max.
IMT Min.
IMT Mean
IMT SD
IMT ROI Length
IMT Measure Length
IMT Quality Index
The Quality Index indicates the reliability of one measurement. Manual trace or re-scan of an image with clear endocardium edges is recommended if the Quality Index value is small.
Tip: To achieve a good trace result, try to place the ROI box parallel with the vessel and adjust the box size to reduce unwanted interference.
For multiple measurements on the same side, vessel and angle, the system calculates the following parameters in the report:
Average Mean IMT
Average Max. IMT
Standard deviation
It also provides the Composite Mean IMT, which is an overall mean value of all IMT mean values derived from the measured items.
ABI
Function: calculates the Ankle Brachial Index (ABI) by measuring the Ankle Systolic Pressure
(ASP) and the Brachial Systolic Pressure (BSP) on a Doppler image.
ABI = ASP/BSP
NOTE: needs to be measured on the left and right sides respectively.
Select [ABI] in the measurement menu.
1. Click [ASP] from the [ABI] menu and enter the value.
2. Click [BSP] from the [ABI] menu and enter the value.
The ABI is calculated by the system automatically.

HIP
The HIP calculation assists in assessing the development of the infant hip. In this calculation, three straight lines are superimposed on the image and aligned with the anatomical features. The two angles are calculated and displayed.
The three lines are:
Pediatrics 11-1
The baseline (BL), connecting the osseous acetabular convexity to the point where the joint capsule and the perichondrium unite with the ilium.
The roof line (RL), connecting the lower edge of the ilium to the osseous acetabular convexity.
The inclination line (IL), connecting the osseous acetabular convexity to the acetabular labrum.
The angles are:
α: the angle between BL and RL.
β: the angle between BL and IL
