5-8 Image Optimization
Persistence
Description
This function is used to superimpose and average adjacent B images, so as to
optimize the image and remove noises.
Operation
Adjust through the [Persistence] item on the menu;
The system provides 7 level of frame average adjustment, the bigger the
value the stronger the effect.
Effects
Persistence can remove image noise to make details to be clearer.
Impacts
Persistence increase may lead to signal missing.
Invert
Description
This function provides a better observation for image display.
Invert
To invert the image horizontally or vertically.
Click [L/R Flip] or [U/D Flip] on the menu to invert the image.
When you flip or rotate an image, the “M” mark will change its position on the screen; the M
mark is located in the upper left corner of the imaging area by default.
Impacts
The function is available in real-time imaging, freeze or cine review status.
iBeam
Description
This function is used to superimpose and average images of different steer
angles to obtain image optimization.
Operation
Adjust through the [iBeam] item on the menu;
Off: no iBeam
On: maximum iBeam optimization
Effects
Images after iBeam processing can be optimized with less spot noise and
higher resolution, so that more details for the structure are revealed.
Impacts
iBeam is not available to phased probe or when trapezoid function is turned on.
Auto Merge
Description
In the Dual-split mode, when the images of the two windows use the same
probe type, depth, invert status and magnification factor, the system will merge
the two images so as to extend the field of vision.
Operation
Turn on/ off the function through the [Auto Merge] item on the menu;
Impacts
Available only for linear probes.
The function is available in real-time imaging, freeze or cine review status.
Gray Map
Description
Adjusting grayscale contras to optimize the image.
Operation
Select among the maps through the [Gray Map] item on the menu. The system
provides 8 gray maps to be selected among.
Impacts
The function is available in real-time imaging, freeze or cine review status.
