5-14 Image Optimization 
Operation  Adjust through the [Edge Enhance] item in the soft menu or menu. 
The system provides 4 levels of edge enhance effects, off represents no 
edge enhance is turned on, and the bigger the value the stronger the 
effect. 
Impacts  Larger edge enhance may lead to noise increasing. 
Dynamic Range 
Description
This function is used to adjust the B image resolution to compress or 
expand the gray display range. The real-time dynamic range value will be 
displayed in the image parameter area in the upper left corner of the 
screen. 
Operation  Adjust through the [Dyn Ra.] item in the soft menu or menu. 
Or adjust it in the image parameter area. 
The adjusting range is 30-160dB in increments of 5. 
Effects  The more the dynamic range, the more specific the information, and the 
lower the contrast with more noise. 
M Soften 
Description
This feature is used to process the scan lines of M images to reject noise, 
making the image details to be clearer. 
Operation  Adjust through the [M Soften] item in the soft menu or menu. 
The system provides 5 levels of M Soften adjustment, the bigger the value 
the stronger the effect. 
5.5  Color Mode Image Optimization 
The Color mode is used to detect color flow information, and the color is designed to judge 
the direction and speed of blood flow. 
Generally, the color above the color bar indicates the flow towards the probe, while the 
color below the color bar indicates the flow away from the probe; the brighter the color, the 
faster the flow speed; while the darker the color, the slower the flow speed. 
5.5.1  Color Mode Exam Protocol 
1.  Select a high-quality image during B mode scanning, and adjust to place the area of 
interest in the center of the image. 
2.  Press <Color> to enter B+Color mode. Use the trackball and <Set> to change 
position and size of the Region of Interest (ROI). 
3.  Adjust the image parameters during scanning to obtain optimized images. 
4.  Perform other operations (e.g. measurement and calculation) if necessary.
