6 Image Acquisition
Operator’s Manual 6 - 11
Smooth
This feature is used to reject the noise and smooth the image.
The bigger the value is, the higher the smooth becomes.
Scale
This function is used to adjust the speed range of color flow, which is adjusted through PRF in the
system. The real-time PRF value is displayed in the image parameter area.
Aliasing may occur if low velocity scale is used and high velocities are encountered.
Low velocities may not be identified when a high velocity scale is used.
Baseline
Refers to the area where the velocity is zero in the scale. Adjust according to the actual situation so
as to get an optimum flow display.
Positive value means to increase the signals below the baseline, and negative value means to
increase the signals above the baseline.
Invert
To set the display mode of the color flow, the color scale will be inverted when the function is
activated.
It is available only for linear probes.
Color Map
This function is a combination of several image parameters, which indicates the display effect of
color image.
Wall Filter (WF)
It filters out low-velocity signals to provide effective information, and this function is used to adjust
the filtered frequency. The real-time value (WF) is displayed in the image parameter area.
Flow signals may be missing.
Smart Track
To optimize image parameters as per the current tissue characteristics for a better image effect. The
angle and the position of the ROI are adjusted after the function is enabled. The area is tracked
without being affected by the dynamic moves.
Priority
This function is used to set levels of the flow display, to display the grayscale signal or color signal.
The color image is preferred with higher value; while grayscale signals are displayed with the lower
value.
Velocity Tag
This function is used to mark the specified velocity range in flow to check the flow function or
specific flow velocity value.
Enable this function, the green mark appears on the color scale. Use trackball and <Set> to set the
marking range and marking position.
iTouch

To optimize image parameters as per the current tissue characteristics for a better image effect.
