Image Optimization 5-17
Color map
Description
This function is a combination of several image parameters, which indicates the
display effect of color image.
Operation Tap the [Color Map] item on the touch screen to select the map.
WF (Wall Filter)
Description
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 in the left corner of the screen.
Operation Rotate the knob under [WF] on the touch screen to adjust the parameters.
Adjust the parameter according to the actual situation and the transducer.
Impacts Flow signals may be missing.
Smart Track
Description 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.
Operation
Tap [Smart Track] on the touch screen under Color/Power mode. The vessels lay in
the middle of the ROI.
Enable the function under B+Color/Power+PW mode. The PW sampling line, SV size
and SV position are adjusted automatically.
Priority
Description
This function is used to set levels of the flow display, to display the grayscale signal or
color signal.
Rotate the knob under [Priority] on the touch screen to complete the adjustment.
The color image is preferred with higher value; while grayscale signals are displayed
with the lower value.
Velocity Tag
Description
This function is used to mark the specified velocity range in flow to check the flow
function or specific flow velocity value.
1. Tap [Velocity tag] on the touch screen to adjust the parameters. The green mark
appears on the color scale.
2. Roll the trackball upwards and downwards to select the marking velocity.
3. Press <Set> to enter the tag range selection status, roll the trackball upwards and
downwards to select the range.
4. Press <Set> to switch between marking position and marking range.
iTouch
Description To optimize image parameters as per the current tissue characteristics for a better image
effect.
