Image Optimization 5-11
5.5.2 PW Mode Image Parameters
In PW mode scanning, the image parameter area in the top-right corner of the screen
displays the real-time parameter values as follows:
◼ During PW mode imaging, the image optimizing menus for B mode and PW mode are
displayed on the touch screen at the same time. You can switch between them by
clicking the mode tabs.
◼ When you adjust the depth of the B mode image, related changes will occur in the PW
mode image as well.
5.5.3 PW Mode Image Optimization
Gain
This function is intended to adjust the gain of the spectrum map. The real-time
gain value is displayed in the image parameter area in the top-right corner of
the screen.
Rotate the <Gain/iTouch> knob clockwise to increase the gain, and counter-
clockwise to decrease it.
The adjusting range is 0-100 in increments of 2.
Increasing the gain will brighten the image and you will see more received
signals. However, noise may also be increased.
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 top-
right corner of the screen.
Click the [SV] on the image menu to adjust the SV size.
Value: 0.5-20 mm.
Roll the trackball to select the SV depth.
The smaller the SV size, the more accurate the result. More details are
obtained when selecting a large SV size.
This function is used to select the operating frequency of the current probe,
the real-time value of which is displayed in the image parameter area in the
upper left corner of the screen, where “F” represents B mode frequency, and
“FH” represents harmonic frequency.
