5-18 Image Optimization
HR Flow (High Resolution Flow)
Description This function enhances the micro vessel imaging effect, and can be used to analyze
the tissue blood supply condition.
Operations
Touch [HR Flow] or the mapping-menu item on the touch screen to turn on HR Flow
status (the [HR Flow] button is highlighted in green when the status is turned on.)
The parameters in HR Flow mode are independent from those in Color mode.
Only the L12-3E/SC6-1E/SC5-1NE/L20-5E/L14-5WE/L9-3E/SD8-1E/V11-3HE/DE11-
3E probes support HR Flow.
B Display
Description To turn on or off the B image display as Color imaging remains active.
Operation Turn on or off the function through the [B Display] item in the menu in the upper left
corner of the screen.
Impacts The function is available in real-time imaging, freeze or cine review status.
5.5 Power Mode Image Optimization
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.
5.5.1 Basic Procedures for Power Mode Imaging
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. Press <Power> to enter B + Power mode. Roll the trackball to change the position of the Region of
Interest (ROI) and press the <Set> key to set. Roll the trackball to change the size and position of
the ROI.
3. Adjust the image parameters during B + Power mode scanning to obtain optimized images.
4. Perform other operations (e.g., measurement and calculation) if necessary.
5.5.2 Power Mode Image Parameters

In Power mode scanning, the image parameter area in the top-right corner of the screen displays
the real-time parameter values as follows:
Parameter F G PRF WF
Meaning Frequency Power Gain
Pulse Repetition
Frequency (PRF)
