Image Optimization  5-151 
2.  Adjust the image parameters to obtain optimized images. 
For details about image parameter adjustment, see “5.2.3 B Mode Image Optimization”. 
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. 
–   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. 
–   Score: the score is among 0 to 3. 
Normal: when there are a lung sliding sign and A line, or isolated B lines (<3), it is marked as N 
in the brackets and the score is 0. 
Moderate: when there are multiple clearly-distributed B lines, it is marked as B1 in the 
brackets and the score is 1. 
Severe: when there are intensively fused B lines, it is marked as B2 in the brackets and the 
score is 2. 
Lung consolidation: when the lung has a symptom that is similar to the liver lesion structure 
and air bronchogram, it is marked as C in the brackets and the score is 3. When 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. Tap the check box under the [Image] or [Diagnosis] tab to select items: 
6.  Press the <Save> key to save the single-frame image and B line calculation results. 
If necessary, press the <Freeze> key again to unfreeze the image. Repeat steps 4-6 to finish 
calculating other points. 
7.  Tap [Report], and select “Fluid Management” from the drop list box of [Report Type] to check 
report. 
For details about report operation, refer to Advanced Volume. 
5.24.2  Overview 
After capturing images, tap [Overview] to enter the Overview screen. The Smart B-line supports 
displaying two types of lung overviews in the main screen. You can switch the two lung overviews using 
the corresponding buttons on the touch screen. 
  Image Map: Displays the ultrasound images of all zones, so as to check the overall lung condition. 
Ever lung zone displays the ultrasound image with the highest percent of the B line area by default. 
If a zone saves multiple ultrasound images, tap the point corresponds to this zone, and tap [Pre 
Item] and [Next Item] to switch the image.
