the lung consolidation and pleural effusion occur at the same time, it is marked as C/P in
the brackets and the score is 3.
–Dist n (B Line distance): indicates the distance between the 2 neighboring lines and is
measured in the pleura line area, among which, n corresponds to the number between the
2 B lines.
– Avg Dist (B Line average distance): indicates the average distance of all B lines.
According to the quantitative index calculated by the system, you can add image and diagnosis
information by clicking the check box beside the items.
6. Tap [Save image] button to save the single-frame image and B line calculation results.
If necessary, tap [Freeze] button again to unfreeze the image. Repeat steps 4-6 to finish
calculating other points.
6.10.2 Overview
After capturing images, tap [Overview] to display the color map of the lung and ultrasound image
of a zone. The color map uses different colors to mark the ultrasound image analysis result of every
lung zone. This analysis result is calculated from the ultrasound image with the highest percent of B
line area.
6.11 Smart VTI
Smart VTI (Velocity-Time Integral) is used to calculate the CO (cardiac output) of the LVOT (left
ventricular output tract), so as to quickly evaluate the cardiac function.
TIP:
Smart VTI supports calculation in real time.
Perform the following procedure:
1. Select a phased probe and Adult Cardiac exam mode.
2. Move the probe to capture an appropriate image of the long axis view of the left ventricular
near the sternum.
3. Tap [Measure] to enter the application measurement. Select the “LVOT Diam” item and the
measurement cursor is displayed.
a. Tap and hold the cursor to move it to the desired position.
b. Tap the cursor to fix the start point.
4. Tap [Freeze] button to unfreeze the image. Move the probe to capture an appropriate image of
the apical five chamber view.
5. Tap [Smart] > [Smart VTI] to enter the Smart VTI mode.
The system will:
– Automatically trace the 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 PW sampling line and sampling volume:
Adjust the PW sampling line position and the PW sampling volume.
