Image Optimization 5-25
Display Format
Description To set the display format of PW mode images with B mode images.
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°.
