Tap the different display format ratio buttons on the touch screen to adjust.
Operations
There are 5 formats for displaying the images: H2:3, V2:3, V3:2, V3:1,
Full.
Duplex/Triplex
Description This function is used to set whether a B image (B + Color image) and PW
image are displayed synchronously.
Tap [Duplex]/[Triplex] on the touch screen to turn the synchronization on or
Operations
off.
HPRF
Description HPRF mode is used when detected velocities exceed the processing
capabilities of the currently selected PW Doppler scale, or when the
selected anatomical site is too deep for the selected PW Doppler scale.
Turn the function on or off using the [HPRF] item on the touch screen.
Operations
HPRF enhances the range for detecting high-velocity flow.
Effects
Baseline
Description Refers to the area where the velocity is zero in the spectrum.
Rotate the knob under [Baseline] to adjust.
Operations
Changes the flow-velocity range to optimize the image.
Effects
Angle
Description This function is used to adjust the angle between Doppler vector and flow
to make the velocity more accurate.
The real-time adjusting angle value is displayed on the right part of the
spectrum map.
Use the <Angle/Steer> key on the control panel to adjust it.
Operations
The adjustable angle range is -89~89°, in increments of 1°.
Quick Angle
Description To adjust the angle faster, in increments of 60°. The real-time value is
displayed on the right part of the spectrum map.
Adjust using the [Quick Angle] item on the touch screen.
Operations
There are 3 angles for quick adjustment: -60°, 0° and 60°.
