5-6 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 in the menu;
The system provides 8 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.
Rotation/ 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] in the menu to invert the image.
Rotation Rotate the image through the [Rotation] item in the menu.
Image can be rotated by the manners in angle of 0°, 90°, 180°, 270°.
When the image is rotated in the angle of 90° or 270°, the depth scale is
displayed on the upper part of the screen.
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 in 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 available only for linear probes, and it is not available 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, rotation 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 in 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.
