Image Optimization 5-23
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.
When you adjust the depth of the B 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 parameters of the
both are combined together to be introduced here.
NOTE: The P4-2NE, P7-3E, P10-4E, SP5-1E, P7-3TE CW5s and CW2s probes support CW mode.

Gain
This function is intended to adjust the gain of spectrum map. The real-time gain
value is displayed in the image parameter area in the upper right corner of the
screen.
Rotate the [PW] knob clockwise to increase the gain, and anticlockwise to
decrease.
The adjusting range is 0-100.
Increasing the gain will brighten the image and you can see more received
signals. However, noise may also be increased.
SV
To adjust the SV position and size of sampling in PW mode, the real-time value of
SV and SVD are displayed in the image parameter area in the upper right corner
of the screen.
Rotate the knob under [SV] on the touch screen to adjust the SV size.
Value: 0.5-20mm.
Roll the trackball to select the SV depth.
The smaller the SV size, the more accurate the result; and more details are
obtained when selecting large SV size.
CW Focus Position
To adjust the CW mode SVD. The real-time focus position value is displayed on
the image parameter area in the upper right corner of the screen.
Roll the trackball to select the focus depth.
Image Quality
Refers to the operating frequency in PW mode of the probe, the real-time value of
