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 or mapping-menu on the touch screen.
The system provides 7 levels of iClear adjustment: off represents no iClear effect, and
the bigger the value, the stronger the effect.
Impacts
It may cause increased noise.
iClear
+
Description iClear
+
is the advanced version of iClear. It can better enhance image quality, reject
noise, provide better contrast resolution, and identify positive lesion.
Operations The operation is the same as that of the iClear item. After configuring the iClear
+
and
iClear
+
Dongle options, the original iClear item becomes iClear
+
in the touch screen.
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 or the mapping-menu item on the touch
screen to adjust the value.
The system provides 0-7 levels of frame average adjustment: the bigger the value the
stronger the effect.
Effects Persistence can remove image noise to make details clearer.

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 or the mapping-menu item on the touch
