5-8 Image Optimization
Persistence
Description
Used to superimpose and average adjacent B images, so as to optimize the image
and remove noises.
Operation Rotate the knob under the [Persistence] item on the touch screen to adjust the value.
The bigger the value is the stronger the effect becomes.
Impacts Persistence can remove image noise to make image clearer.
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.
Tap [U/D] or [L/R] on the touch screen to adjust the parameters, and identify the
image orientation through the "M" mark on the screen.
Tap [Rotation] on the touch screen to adjust the parameters.
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.
The “M” mark indicates the orientation of the image; the M mark is located on the top of the imaging
area by default.
iBeam
This function is used to superimpose and average images of different steer angles to
obtain image optimization.
Operation Rotate the knob under [iBeam] to adjust the parameters.
The system provides various iBeam in B mode. iBeam is disabled when it is off.
Images after iBeam processing can be optimized with less spot noise and higher
resolution, so that more details for the structure are revealed.
Impacts The phased probe does not support iBeam.
Image Merge
Description
In the Dual-split mode, when the images of the two windows have 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 Tap [Auto Merge]] on the touch screen to enable/disable the function.
Impacts Only for linear probes.
Gray map
Description Adjusting grayscale contrast to optimize the image.
Operation Tap [Gray Map] on the touch screen to complete the adjustment.
