6 Image Acquisition
NOTE:
• During color mode imaging, menus of image optimizing for B-Mode and C-Mode are
displayed on the touch screen at the same time. You can switch between the 2 modes by
clicking the mode tabs.
• 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.
6.3.1 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 and <Set> to change position and size of the Region of Interest (ROI).
4. Adjust the image parameters during scan to obtain optimized images.
6.3.2 Color Mode Image Parameters
In Color mode scan, the image parameter area on the right side of the screen displays the real-time
parameter values as follows:
ROI Adjustment
To adjust the width and position of ROI in Color mode.
•
When the ROI box is solid line, roll the trackball to change its position.
• When the ROI box is dotted line, roll the trackball to change the size.
• Press <Set> to switch between the solid line and the dotted line status.
The larger the ROI box is, the lower the frame rate becomes, and the lower the resolution and color
sensitivity will be.
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.
Image Quality
Refers to the transmitting frequency in Doppler mode of the probe, the real-time value of which is
displayed in the image parameter area.
B/C Align
To set and constrain the maximum width of the B mode image to that of the Color ROI.
