Image Optimization 5-27
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 and Dual B imaging modes.
It supports single-frame and multi-frame image file detection in B mode.
Smart B-line is an option.
5.7.1 Basic Procedures for Smart B-line
Perform the following procedure:
1. Select a proper 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 “5.1.2 Image Adjustment”.
3. Tap [Smart B-line] on the right side of the operating panel to enter Smart B-line mode.
Tap to select different zone combinations for examination.
4. Select a desired zone, and tap [AutoCalc].
The system automatically starts tracing the B line sampling area, and automatically recognizes
and traces the B line in frame.
If necessary, you can adjust the B line sampling area: Tap the dotted circle and drag the
sampling line to change the position.
5. Tap [Freeze] to freeze the image.
The system automatically calculates the quantitative index, and the calculation results are
displayed on the screen.
B Lines: indicates the number of B lines of the current frame. The number can be 1, 2, 3,
4, or ≥5. When the number is equal to or greater than 5, the system does not display a
specific number.
Percent: indicates the percent of the B lines area against the total sampling area.
