Doppler Mode Measurements
Four basic measurements can be made in Doppler Mode.
• Velocity
•  TAMAX, TAMIN, and TAMEAN (Manual or Auto Trace)
•  Two Velocities with the Slope and Time Interval between 
them
• Time Interval
NOTE:  The following instructions assume that you do the following:
1.  In the B-Mode part of the display, scan the anatomy you 
want to measure.
2.  Go to the Doppler Mode part of the...
