Operator’s Manual 6 - 25
NOTE:
• During PW/CW mode imaging, menus of image optimizing for B Mode and PW/CW mode are
displayed on the touch screen at the same time; if there is also Color mode (Power mode)
working, menus of certain modes will also be displayed on the touch screen synchronously,
and you can switch by clicking the mode tabs.
• In PW/CW mode, acoustic power of the transducer is synchronous with that of B mode.
• When you adjust the depth or TGC of the PW/CW-Mode image, related changes will occur in
PW/CW mode image as well.
6.9.1 PW/CW Mode Image Scanning
Perform the following procedure:
1.
Select a premium image during B mode or B+ Color (Power) scan, and adjust to place the area
of interest in the center of the image.
2. Press <PW>/<CW> to set the position of the sample line by moving the trackball left and right.
Set the SVD by moving the trackball up and down, and adjust the angle and SV size according
to the actual situation.
3. Press <PW>/<CW> again or <Update> to enter PW/CW Mode and perform the examination.
Observe and calculate the data based on B mode or Color mode image. You can also adjust the
SV size, angle and depth in the real-time scan.
The parameter area appears in the right of the screen, see the figure below:
4. Adjust the image parameters during PW/CW mode scan to obtain optimized images.
TIP:
The sampling line is displayed for one procedure operation. Press <PW>/<CW> to enter M mode.
