6.11 Smart B-line
The lung acoustic impedance difference increases with the increase of lung liquids. The ultrasound
waves produce strong reverberations in the lung at different depth. After multiple reflections, the
comet tail sign is formed, which is perpendicular to the pleura plane. Starting from the pleura line,
the comet tail sign moves along with the lung and extends to the far field. The reverberation line
perpendicular to the pleura plane is called Smart B-line.
Smart B-line is used to detect the B line of the lung in B mode. It supports B-line detecting in both
real-time and freeze modes.
• Smart B-line is only available in Single B imaging mode.
• It supports single-frame and multi-frame image file detection in B mode.
• Smart B-line is an option.
6.11.1 Basic Procedures for Smart B-line
Perform the following procedure:
1. Select an appropriate probe and exam mode. The system enters the B mode by default.
2. Adjust the image parameters to obtain optimized images.
For details about image parameter adjustment, see “6.1 B Mode”.
3. Tap [Smart B-line] on the touch screen or the user-defined key to enter Smart B-line mode.
Tap [Scanning Areas] to select different zone combinations for examination.
4. Select a desired zone, and tap [Auto Calc].
The system automatically starts tracing the B line sampling area, and automatically recognizes
and traces the B line in frame.
If necessary, use the trackball/trackpad and <Set> keys to adjust the B line sampling area.
5. Press the <Freeze> key to freeze the image.
The system automatically calculates the quantitative index, and the calculation results are
displayed on the screen.
