Image Optimization 5-33
Operation
Turn the knob under [Gray Map] on the touch screen to complete the adjustment.
There are 10 different gray maps available.
Display Format
Description
To set the display proportion of PW mode image and B mode image.
Operation
Touch the different display format ratio buttons on the touch screen to adjust.
There are 5 formats to display the images: H2:3, V2:3, V3:2, V3:1, Full.
Duplex/Triplex
Description
This function is used to set if B image or B+Color image (Power) is scanned
synchronously.
Operation
Tap [Duplex/Triplex] on the touch screen.
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 selective PW Doppler scale.
Operation
Tap [HPRF] on the touch screen.
Gray Map
HPRF enhances the range of detecting high-velocity flow.
Baseline
Description
Refers to the area where the velocity in zero in the spectrum. The map changes after
being edited.
Operation
Toggle <Baseline> to complete the adjustment.
Gray Map
To optimize the image, adjust baseline according to the actual situation to change the
range of flow velocity.
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.
Operation
Rotate the <Angle> knob on the control panel to adjust.
The adjustable angle range is -80~89° in increments of 1°.
Quick Angle
Description
To adjust the angle faster in increments of 60°, and the real-time value of which is
displayed on the right part of the spectrum map.
Operation
Tap [Quick Angle] on the touch screen adjust the parameters.
There are 3 angles for quick adjustment: -60°
，
0°
