Image Optimization 5-25
Operations
Tap the different display format ratio buttons on the touch screen to adjust.
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.
Operations
Tap [Duplex]/[Triplex] on the touch screen to turn the synchronization on or
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.
Operations
Turn the function on or off using the [HPRF] item on the touch screen.
Effects
HPRF enhances the range for detecting high-velocity flow.
Baseline
Description
Refers to the area where the velocity is zero in the spectrum.
Operations
Rotate the knob under [Baseline] to adjust.
Effects
Changes the flow-velocity range to optimize the image.
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.
Operations
Use the <Angle/Steer> key on the control panel to adjust it.
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.
Operations
Adjust using the [Quick Angle] item on the touch screen.
There are 3 angles for quick adjustment: -60°, 0° and 60°.
