6 Image Acquisition
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.
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.
iTouch
To optimize image parameters as per the current tissue characteristics for a better image effect.
Smart tracking
To optimize image parameters as per the current tissue characteristics for a better image effect.
When Smart Tracking is turned on, the system optimizes ROI angle and position automatically to
achieve an active tracking by reducing the impact of patient respiratory movement.
6.3 Power Mode
Power mode provides a non-directional display of the blood flow in terms of intensity as opposed to
flow velocity.
DirPower (Directional Power mode) provides additional information of the flow direction toward
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.
6.3.1 Power Mode Image Scanning
Perform the following procedure:
1. Select a high-quality image during B mode or B + Color scanning, and adjust to position the
area of interest in the center of the image.
2. Tap [Power] on the right side of the operating panel to enter Power mode.
3. Change the size and position of the ROI.
– Tap the corner of the ROI and drag to change the size.
– Tap inside the ROI box and drag to change the position.
4. Tap [Image] to open the image menu. Adjust the parameters to optimize the image.
6.3.2 Power Mode Image Parameters
Because both are based on Doppler color imaging, the adjustments of Power mode are same with
these of Color mode’s. Hence, only the adjustments of Power mode are introduced.
Power Gain
Refers to the overall sensitivity to flow signals, and this function is used to adjust the gain in Power
mode. The real-time gain value is displayed in the image parameter area.
