Color Flow Mode (CFM) Controls (cont’d)
Acoustic output affects the transmit power for both B-Mode and CFM signals.
TGC and B/M Gain function only on the B-Mode image displayed.
The Dual Format keys work the same as in dual B-Mode, but both B-Mode and CFM are displayed on the left and right
sides of the screen.
The keyboard controls that effect CFM are as follows:
1.
Color Doppler Gain—Adjusted overall
received echo gain for CFM. To
increase/decrease, turn the control
clockwise/counterclockwise.
2.
CFM/Spectrum Invert—Inverts Color
Flow Map assignments.
3.
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.
4.
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.
5.
Color Flow Window Size (Scan Area)—Used to assign trackball control to adjust size/position of the CFM window.
