6 Image Acquisition
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.
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.
HR Flow
Enhance tiny vessel display to analyze the blood supply of the vessel in pathological organ.
ART Flow
Enhance the blood sensitivity and penetrability in time period.
ART Flow Duration appears at the right bottom of the screen after the function is enabled. The
penetrability of color image is enhanced during this time period.
After ART Flow Duration is finished, the ART Flow interval appears at the right bottom of the
screen. The ART Flow is enabled again until the interval is finished.
Glazing Flow
This function applies glazing effect to the vessel flow, so as to make it more stereoscopic.
The color codes of the vessel velocity and power will change after the Glazing Flow function is
enabled. During diagnosis, users should exam the ROI without using the Glazing Flow function.
Otherwise, misdiagnosis may occur.
UMA (Ultra-Micro Angiography)
This function filters out low-velocity tissue signals so as to optimize the display of blood flow of
low velocity in capillary vessels.
After entering UMA, select the sub-mode:
•
cUMA (Color UMA): it is the velocity sub-mode of Color mode, used to observe color flow
and provide flow direction and velocity information.
