6 Image Acquisition
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.
WF (Wall Filter)
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.
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.
The linear probes for Upper Ext Artery, Upper Ext Vein, Lower Ext Artery, Lower Ext Vein,
carotid, EM Vascular exam supports the smart track.
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/trackpad 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.
6.3 Power Mode
Power mode provides a non-directionally display of blood flow in the form of intensity as opposed
to flow velocity.
DirPower (Directional Power Mode) provides the additional information of flow direction towards
or away from the probe.
In Power mode, the acoustic power is synchronous with that of B mode. Adjustment of the depth to
the B mode image will lead to corresponding changes in Power mode image.
