5-96 Image Optimization
Operation Rotate the knob under the [Fixed ROI] item on the touch screen to adjust the fixed
size of the ROI, or press the <Set> key and roll the trackball to adjust the ROI position
and scale. The ROI includes lesions and surrounding normal tissues.
The “+” sign indicates the ROI center, and the Depth value of the ROI center is
displayed at the bottom right corner of the screen.
Display Format
Description
Used to adjust the display format of ultrasound image and the Elasto image, and
return to the previous state.
Operation
Tap each soft key on the touch screen to complete the adjustment.
The system provides 3 types of display format:
H 1:1; V 1:1; Full.
Impacts More accurate result is obtained based on the actual situation.
HQElasto
Description
Turn on high-quality scanning mode to optimize penetration.
Operation Tap [HQElasto] to enable the function and the button will be highlighted.
Impacts
When the feature is activated, the system turns into single-frame scanning mode.
Pressing <Update> acquires one frame image of B and Elasto.
RLB Map
Description
Used to help the user judge the region where it is suitable for elasto measurements
based on the distinctive colors in elasto image in quality map.
The RLB Index shows the signal reliability of the STE inside the ROI, and it helps the
user judge the effectiveness of the current elasto measurement.
Operation Tap [RLB Map] to select the display mode of the RLB map, B-mode image and elasto
image.
The higher the RLB Index is, the more reliability the signal becomes; vice versa.
There are three colors showing the RLB Index: Red (low reliability), Yellow (medium
reliability) and White (high reliability).
Impacts
The color in High area is suitable for the imaging of shear wave elastography.
The color in Low area is not suitable for the imaging of shear wave elastography (liquid,
gas, bone, etc). It can be used as a tool to detect the tissue or the lesion.
RLB View
Description
This feature supports the less qualified region or the region that fails to receive shear
waves of the gas or liquid to be displayed in hollow.
Operation
Tap [RLB View] on the touch screen to enable the function and the button will be
highlighted.
After the RLB View function is enabled, the less qualified region is displayed in
hollow. The hollow region can be seen in B images. The hollow region corresponds
to the purple region in the reliability image.
