F4
✖
Remark:
• The spectral Doppler gain value is shown at the Spectral Doppler
Image Info area (the
GN
).
10.2.6 Steer Angle
STEER ANGLE
Use this function to adjust the spectral Doppler cursor for linear array probes
1
.
• Select
STEER ANGLE from the context menu.
• Use the
MENU
knob to change the angle of the spectral Doppler cursor.
10.2.7 Flow Invert
In PW or CW mode, press the
Finv
key to invert the spectral display in relation to the flow
direction. The displayed spectrum is inverted around the baseline.
When Flow Invert is turned on,
Invert
indicator appears on top right of the spectral display.
10.2.8 Spectral Doppler Frequency
FREQUENCY
The spectral Doppler frequency controls the transmit frequency.
• press
to select FREQUENCY .
• turn the function knob to change the frequency value.
✖
Remark:
• The spectral Doppler frequency value is displayed on the screen at
the Spectral Doppler Image Info area (
FRQ
).
10.2.9 Sweep Speed
SWEEP SPEED
Similar to the sweep speed in the M mode, this speed determines how fast the spectral
Doppler display is updating.
• Press
to select SWEEP SPEED .
• Turn the function knob to change the sweep speed.
10.2.10 Baseline
BASELINE
Moving the baseline increases the velocity range in one direction. The vertical axis repre-
sents the scale for flow velocity (in cm/s).
• Select
BASELINE from the context menu.
• Turn the
MENU
knob to adjust the amount of the baseline move.
