Operations
Select using the [WF] item or the mapping-menu item on the touch screen.
There are 8 levels of wall filter function available. Select the value according to the
actual situation.
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 angle and the
position of the ROI are adjusted automatically. The vessels lay in the middle of the ROI.
