Doppler Controls (cont’d)

Several controls affect the B-Mode portion of the display and not the echoes in the Doppler spectrum.  These are TGC,
Depth, B/M Gain, Scan Area and Reverse keys.  See 

Quick Start 12 for comments on these controls.

The keyboard controls that affect Doppler are as follows:

1.

M/D Cursor—Assigns trackball control to the Doppler cursor.

2.

Audio Volume—Used to adjust Doppler audio volume output.  To
increase/decrease, turn the control clockwise/counterclockwise.

3.

Doppler Spectral Gain—Adjusts overall received echo gain for
Doppler.  To increase/decrease, turn the control clockwise/
counterclockwise.

4.

Theta Angle Correction—Adjusts angle correction for flow velocity
calculation.  To adjust the angle clockwise/counterclockwise relative
to the probe face, turn the control clockwise/counterclockwise.

5.

CFM/Spectrum Invert—Inverts Doppler spectrum assignments.

6.

Velocity Scale—Adjusts velocity scale to accommodate faster/slower blood flow velocities.  To increase/decrease,
press the top/bottom of the Velocity Scale rocker switch.

7.

Baseline Shift—Minimize aliasing by assigning more of the overall displayed velocity scale to forward or reverse flow.
To shift the baseline up/down, press the top/bottom of the Baseline Shift rocker switch.

8.

B Pause—Freezes the B-Mode image while keeping the Doppler spectrum display active.  Press to view CW Doppler.
