Image Optimization 5-13
Gray map
Description Adjusting grayscale contrast to optimize the image.
Operation Tap [Gray Map] on the touch screen to complete the adjustment.
Edge Enhance
Description
This function is used to increase image profile, so as to distinguish the image
boundary.
Operation Rotate the knob under [Edge Enhance] on the touch screen to adjust the parameters.
0 represents no edge enhance is turned on, and the bigger the value is, the stronger
the effect becomes.
Impacts Larger edge enhance may lead to noise increase.
Dynamic Range
Description
Adjusts contrast resolution of an image, compresses or expands gray display range.
The real-time dynamic range value will be displayed on the image parameter area on
the top of the screen.
Operation Rotate the knob under [Dyn Ra.] on the touch screen to complete the adjustment.
Impacts The more the dynamic range is, the more specified the information appears.
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 Rotate the knob under [M Soften] to adjust the parameters on the touch screen.
0 represents the function is disabled. The bigger the value is, the stronger the effect
becomes.
5.4 Color Mode Image Optimization
The Color mode is used to detect color flow, 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 is, the faster the flow speed
becomes; while the darker the color is, the slower the flow speed becomes.
5.4.1 Color Mode Exam Protocol
1. Select a premium image during B mode scan, and adjust to place the area of interest in the center
of the image.
2. Press <C> 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 scan to obtain optimized images.
4. Perform other operations (e.g. measurement and calculation) if necessary.
