5-102 Image Optimization
E Avg
Description
Used to optimize the measurement result via equalizing the elasto metric of the current
frames and the previous frames.
Operation
Rotate [E Avg] knob to adjust the value.
The adjusting range is: 1-7 in increment of 1.
Off represents the E Avg is disabled. The larger the scale is, the more the frames of the
elasto metric are equalized.
Impacts
Decrease the image noise.
E bar
Description
This feature supports the elasto curve to be displayed based on different statistical
amounts.
Operations
Tap [E bar] on the touch screen to adjust the parameter.
M-STB Index/Sensibility
Description
The STE imaging can easily be affected by respiration, pulse of the main artery, or
transducer movement, which may cause uncertainty and unreliability. The M-STB Index
helps users judge whether the current elasto image is captured in stable state. Based
on the judgment, capturing method, capturing part, and patient cooperation can be
adjusted accordingly.
Operation
Tap [M-STB Index] on the touch screen to enable the function and the button will be
highlighted. Then the M-STB Index is displayed at the upper side of the image.
Grading definition of the M-STB Index: 1 star indicates that the motion interference is
extremely strong, and it is not recommended to use the elasto image; 2 stars indicates
that the motion interference is relatively strong, and it is not recommended to use the
elasto image; 3 stars indicates that the motion interference is general, and it is not
recommended to use the elasto image; 4 stars indicates that the motion interference is
not strong, and the image can be used; 5 stars indicates that the motion interference is
few or slight, and it is recommended to use the elasto image.
Tap [M-STB Sensi.] on the touch screen to set the grading threshold of the M-STB
Index.
The stronger the sensibility of the motion stability is, the higher the judgment accuracy
of the motion interference becomes.
Effects
Users can determine the interference degree of the currently-captured elasto image
according to the M-STB Index.
Scale
Description
Used to optimize the display effect of the elasto average metric inside ROI via changing
the Y-axis size.
Operation
Rotate [Scale] knob to adjust the value.
The adjusting range is: 0-9 in increment of 1.
Impacts
If elasto metric average value inside ROI of a certain frame image exceeds the
maximum scale on the elasto curve, elasto metric will display in the maximum scale
value.
