Image Optimization 5-7
iClear
Description
The function is used to enhance the image profile so as to distinguish the
image boundary for optimization.
Operations
Adjust using the [iClear] item on the touch screen.
The system provides 1-4 levels of iClear adjustment: off represents no
iClear effect, and the bigger the value the stronger the effect.
Impacts
It may cause increased noise.
Persistence
Description
This function is used to superimpose and average adjacent B images, so
as to optimize the image and remove noise.
Operations
Rotate the knob under the [Persistence] item on the touch screen to adjust
the value.
The system provides 7 levels of frame average adjustment: the bigger the
value the stronger the effect.
Effects
Persistence can remove image noise to make details clearer.
Impacts
Increasing Persistence may lead to missing signals.
Rotation/Invert (U/D Flip and L/R Flip)
Description
The function provides better observation for image display.
Rotation
Rotate the image using the [Rotation] item on the touch screen.
Images can be rotated by 0°, 90°, 180° and 270°.
When the image is rotated by 90° or 270°, the depth scale is displayed in
the top part of the screen.
Invert (U/D
Flip and
L/R Flip)
To invert the image horizontally or vertically.
Tap [U/D Flip] or [L/R Flip] on the touch screen to invert the image
Effects
You can identify the image orientation using the “M” mark on the screen.
By default, the M mark is located in the top-left corner of the imaging area.
iBeam (Spatial Compound Imaging)
Description
This function is used to superimpose and average images of different
steer angles to achieve image optimization.
Operations
Adjust using the [iBeam] item on the touch screen.
The system provides difefnt levels of iBeam adjustment in single B mode.
Off represents no iBeam.
Effects
Images can be optimized with less spot noise and higher resolution, so
that more details for the structure are revealed.
Impacts
iBeam is valid for linear and convex probes, and it is not available when
the ExFOV function is turned on.
