6 Image Acquisition
Two pages of adjustable parameters are displayed on the touch screen as well; where, shared
parameters and left window parameters are displayed in the B (L) page, while right window
parameters are displayed in the B(R) page.
In the image parameter area, parameters of the both windows are displayed.
It supports the magnification of the image.
LGC
Adjust the gain along the scan line to improve the lateral resolution of the image.
TIP:
The system provides several preset parameters for imaging.
Echo Boost
The contrast is increased and the noise is decreased with the clear boundary after generating the
function.
TIP:
Use phased probe to activate the function in cardiac mode.
6.2 Color Mode
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.
TIP:
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.
6.2.1 Color Mode Image Scanning
Perform the following procedure:
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.
3. Use the trackball/trackpad and <Set> to change position and size of the Region of Interest
(ROI).
4. Adjust the image parameters during scan to obtain optimized images.
6.2.2 Color Mode Image Parameters
Color Gain
Refers to the overall sensitivity to flow signals. The real-time gain value is displayed in the image
parameter area.
Increasing the gain will increase the flow signal presented as well as noise, while the signals may be
missing when the gain is adjusted too low.
