Image Optimization 5-21
5.6.2
V Flow Mode Image Parameter
The parameters on B mode and Color mode are same with these on V Flow mode during V Flow
scan.
During V Flow scan, menus of image optimizing for B mode, Color mode and V Flow are displayed
on the touch screen at the same time. You can switch among them by tapping the mode tabs.
In Color Mode, acoustic power is synchronous with that of B Mode. Adjustment of the depth to the B
mode image will lead to corresponding changes in V Flow mode image.

V Flow Mode Image Optimization
Quality
Description
To adjust the image quality
Operation
Tap [Quality] to adjust the parameter.
There are seven values of the spectrum.
Impacts
The filling, smoothness and the image effect have slight change after completing the v
flow adjustment.
V Flow Map
Description
This function is a combination of several image parameters, which indicates the display
effect of color image. The blood flow information is displayed via switching among the
different spectrums.
Operation
Tap [V Flow Map] to adjust the parameter.
There are four values of the spectrum.
Impacts
The color of the arrow changes after completing the adjustment.
V Flow Gain
Description
Used for adjusting the sensitivity of the blood flow signal.
Operation
Tap [V Flow Gain] to adjust the parameter.
The adjusting range is: 0-8 in increment of 1.
Impacts
The filling of the blood becomes more with the value becoming larger, and the arrows
becoming more.
The filling of the blood becomes less with the value becoming smaller and the arrows
becoming less.
Arrow Density
Description
Used for adjusting the arrows’ number in the unit area.
Operation
Rotate the knob under [Arrow Density] item on the touch screen.
The adjusting range is: 1%-10% in increment of 1%.
Impacts
The arrow becomes more with the density becoming more compacted.
The arrow becomes less with the density becoming fewer.
