PW, CW (Cardiac exam only) Toggle
between PW Doppler and CW
Doppler.
The current selection appears in the
upper left-hand screen.
Angle
Correction
Corrects the angle to 0°, +60°, or
-60°.
Gate Size Settings depend on transducer and
exam type.
In TCD or Orb exams, use the
touchpad to specify the Doppler
gate depth (the depth of the center
of the gate in the Doppler image).
The Doppler gate depth indicator is
on the lower right-hand screen.
TDI On,
TDI Off
Select TDI On to turn on tissue
Doppler imaging. When on, TDI
appears in the upper left-hand
screen. The default is TDI off.
Available only in cardiac exams.
Steering Select the desired steering angle
setting. The PW Doppler angle
correction automatically changes
to the optimum setting.
• -15 has an angle correction of
-60°.
• 0 has an angle correction of 0°.
• +15 has an angle correction of
+60°.
You can manually correct the angle
after selecting a steering angle
setting. (See “To display the D-line”
on page 28.)
Available on select transducers.
Page x/x Indicates which page of options is
displayed. Select to display the next
page.
Scale Select the desired scale (pulse
repetition frequency [PRF]) setting.
(To change the Doppler scale to
cm/s or kHz, see “Presets setup” on
page 22.)
Line Sets the baseline position.
(On a frozen trace, the baseline can
be adjusted if Live Trace is off.)
Invert Vertically flips the spectral trace.
(On a frozen trace, Invert is
available if Live Trace is off.)
Volume Increases or decreases Doppler
speaker volume (0-10).
Wall Filter Settings include Low, Med, High.
Sweep Speed Settings include Slow, Med, Fast.
