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 accommodate 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 Tap [Speed] on the touch screen to adjust the parameters.
The smaller the value is, the slower the speed becomes.
Effects
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 Rotate the knob under [T/F Res] on the touch screen to adjust the parameters.
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

displayed in the image parameter area in the left corner of the screen.
Operation
Rotate the knob under [WF] on the touch screen to adjust the parameters.
Adjust the parameter according to the actual situation and the transducer.
Impacts
Flow signals may be missing.
