Image Optimization 5-97
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 [HQElasto] to enable the function (the soft key is highlighted). The quality map
appears on the left side of the image.
With both real-time ultrasound image and elasto image displaying, the real-time
ultrasound image is replaced with the quality image.
With only elasto image displaying, the elasto image is replaced with the quality 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.
