5-10 Image Optimization
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.
The system provides 15 levels of M Soften adjustment, the bigger the
value the stronger the effect.
5.4 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.
5.4.1 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.
5.4.2 Color Mode Image Optimization
îš„ In Color mode scanning, the image parameter area in the upper left corner of the
screen displays the real-time parameter values as follows:
Parameter F G PRF WF
Meaning Frequency Color Gain Pulse Repetition Frequency (PRF) Color Wall Filter
îš„ During Color mode imaging, menus of image optimizing for B mode and M mode are
displayed on the soft menu. You can switch between the 2 modes by clicking the
mode tabs.
îš„ In Color mode, acoustic power is synchronous with that of B mode. Adjustment of the
depth to the B mode image will lead to corresponding changes in Color mode image.
5.4.3 Color Mode Image Optimization
Color Gain
Description Refers to the overall sensitivity to flow signals, and this function is used to
adjust the gain in Color mode. The real-time gain value is displayed in the
image parameter area in the upper left corner of the screen.
