5-32 Image Optimization
Invert
Description
This function is used to set the display manner of spectrum.
Operation
Tap [Invert] on the touch screen to complete the adjustment.
Then the color bar can automatically invert when the color flow is steered to a certain
angle to accommodat
e operators’ habit of distinguishing flow direction. Select [Auto
Invert] via [Setup]
[System Preset]
[Image].
It is available only for linear probes.
Speed
Description
This function is used to set the scan speed of PW mode imaging.
Operation
Rotate the knob under [Speed] on the touch screen to adjust the parameters.
There are 6 levels of scan speed available, the smaller the value is, the slower the speed
becomes.
Gray Map
Changing the speed makes it easier to identify the cardiac cycles and to detect more
details.
T/F Res
Description
Adjusts for a balance between time resolution and spatial resolution.
Operation
Tap [T/F Res] on the touch screen to adjust the parameters.
There are 6 levels of T/F Res values available, adjust according to the actual situation
and the transducer.
WF (Wall Filter)
Description
To display the image accurately, it adjusts the cut-off used in the wall filter, and filters out
the flow noise which is produced by vessel wall vibration. The real-time value is
displayed in the image parameter area in the right corner of the screen.
Operation
Tap [WF] on the touch screen to adjust the parameters.
There are 7 levels of wall filter function available, adjust according to the actual situation
and the transducer.
Impacts
Flow signals may be missing.
TInt Map
Description
This function provides an imaging process based on color difference rather than gray
distinction.
Operation
Rotate the knob below [Tint Map] on the touch screen to complete the adjustment.
The system provides 8 tint maps to be selected among.
Gray map
Description
Selects among post processing map curves to optimize grayscale images.
