Image Optimization
5-15
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.
5.5.2 Color Mode Image Optimization
„ In Color mode scanning, the image parameter area in the upper left corner of the
screen displays the real-time parameter values as follows:
Display F 3.3 G38 IP 1 WF 43 PRF 0.4k
Parameter Frequency Color
Gain
Color
IP Color Wall
Filter Pulse Repetition
Frequency PRF
„
Parameters that can be adjusted to optimize the Color mode image are indicated in
the following.
Adjustment Items
Control Panel Gain, Depth
Menu and Soft
Menu
B/C Wide, Frequency, Priority, Baseline, Packet Size, Dual Live,
Color IP, Map, A. power, Focus Position, Scale, Flow State, WF,
Invert, Line Density, Smooth, Persistence, B Display, Steer
„ In Color mode, acoustic power is synchronous with that of B mode. Adjustment of the
depth or zoom to the B mode image will lead to corresponding changes in Color mode
image.
„ During Color mode imaging, menus for B mode and Color mode are displayed in the
soft menu at the same time; use the left/right keys of directional soft menu controls to
switch the menus of B mode and Color mode.
„ Items that appear in the menu or the soft menus are dependent upon preset, which
can be changed or set through "[Setup] → [Image Preset]"; please refer to "5.13
Image Preset" for details.
5.5.3 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.
