5-8 Image Optimization 
Invert(U/D 
Flip  and 
L/R Flip) 
To invert the image horizontally or vertically. 
Click [L/R Flip] or [U/D Flip] in the menu or the soft menu to invert the 
image. 
Rotation  Rotate the image through the [Rotation] item in the menu or the soft menu.
Image can be rotated by the manners in angle of 0°,  90°, 180°, and 270°. 
When the image is rotated at the angle of 90° or 27 0°, the depth scale is 
displayed on the upper part of the screen. 
When you invert or rotate an image, the “M” mark will change its position correspondingly 
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 soft menu or menu. 
The system provides 3 levels of iBeam adjustment, off represents no 
iBeam, and while 2 represents 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  When linear probe is being used, iBeam function is not available when 
trapezoid function is turned on or B steer is adopted. 
Image 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 or off the function through the [Img Merge] item in the soft menu or 
menu. 
Impacts  Image Merge is available only for linear probes. 
The function is available in real-time imaging, freeze or cine review status.
Gray Map 
Description
This function applies the gray correction to obtain the optimum images. 
Operation  Select among the maps through the [Gray Map] item in the soft menu or 
menu. 
You can also adjust through the grayscale bar: move the cursor to the 
grayscale bar and press <Set> on the control panel to adjust. 
The system provides 8 groups of gray map. 
Impacts  The function is available in real-time imaging, freeze or cine review status.
