near the sternum.
3. Tap [Measure] to enter the application measurement. Select [Advanced] -> [LVOT Diam] item
and the measurement cursor is displayed on the screen.
a. Tap and hold the hand icon to move the green cursor to the desired position.
Tap the arrows around the hand icon to fine-tune the cursor position if needed.
b. Tap the hand icon to fix the start point.
c. Tap and hold the hand icon to move the cursor to the desired position, you can also tap
the arrows around the hand icon to fine-tune the cursor position.

apical five chamber view.
5. Tap [Smart VTI] on the right side of the operating panel to enter the Smart VTI mode.
The system will:
 Automatically trace the color VOI, and PW sampling line and sampling volume.
 Automatically recognize the cardiac cycle: when there are ECG inputs, the ECG signals
are preferred; when there are no ECG signals, the system automatically starts calculation.
 Trace the LVOT spectrum in a cardiac cycle in real time to gain the VTI, HR, and CO
results of the LVOT.
6. If necessary, adjust the color VOI, and PW sampling line and sampling volume.
After adjustment, the LVOT spectrum tracing and calculation results display in real time.
7. Tap [Freeze] to freeze the image, and check the Smart VTI calculation results.
If necessary, you can edit the LOVT spectrum manually:
a. Tap [Edit VTI] on the touch screen.
b. Move the cursor to the spectrum tracing line and tap the hand icon.
c. Tap and hold the hand icon to trace a line.
After tracing, the calculation results display in real time.
8. Tap [Save VTI] to save the Smart VTI calculation results of the current cardiac cycle to the
database.
9. Tap [Graph] to check the quantitative index trend curve.
VTI, SV, and CO have different trend curves and are differentiated by colors.
5.9 Smart IVC
Smart IVC is used to automatically measure the IVC inner diameter and calculate the change rate
in the B mode image. Measure the IVC (Inferior Vena Cava) in real time, and the system
automatically tracks and measures the changes of IVC inner diameter. It can be used to assist in
treatments, such as volume estimation and fluid infusion.
NOTE:
The cardiac package should be configured in advance.
Smart IVC is an option.
