5-24 Image Optimization
CW module is optional.
5.7.1 PW/CW Mode Exam Operation
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 left of the screen, see the figure below:
PW Sampling Line Adjustment SV SV Size
Angle Angle
SVD SV depth
CW Sampling Line Adjustment Angle Angle
SVD Focus depth
4. Adjust the image parameters during PW/CW mode scan to obtain optimized images.
5. Perform other operations (e.g. measurement and calculation) if necessary.
Tips: the M-mark line is displayed for one procedure operation. Press <PW>/<CW> to enter M mode.
For details, please refer to Chapter 5.1.3 Quickly Saving Image Settings.
5.7.2 PW/CW Mode Image Parameters
In PW/ CW mode scan, the image parameter area on the left side of the screen shows the real-time
parameter values as follows:
Items F G WF PRF SVD SV Angle
Meaning Frequency
PW/CW

WF (Wall

Pulse Repetition

SV
depth

Angle
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.
Most of the parameters are the same for the PW Mode and CW Mode, so the both are combined
together to be introduced here.
