D Trace
This is a basic measurement that is available in Spectral Doppler Mode only. You can specify a point in
a Spectral Doppler image and trace a curve from that point to calculate the velocity, integral value and
average velocity of blood ow.
1. Select the Soft Menu dial-button [1] D Trace. “D Trace is displayed in the user information area.
2. Trace a curve. The method for measuring a curve is the same as in “2D Line Trace.
3. When the measurement is nished, its result is shown on the screen.
PSV: Peak Systolic Velocity
EDV: End Diastolic Velocity
PI: Pulsatility Index
RI: Resistivity Index
S/D: Ratio of PSV to EDV
Vmax: Max Velocity
Vmean: Mean Velocity
PGmax: Max Pressure Gradient
PGmean: Mean Pressure Gradient
VTI: Velocity Time Integral
PHT: Pressure Half Time
Acc: Acceleration
AccT: Acceleration Time
Dec: Deceleration
DecT: Deceleration Time
The equations used for D Trace measurement are as follows:
NOTE:
If Application is set to Cardiac at Utility > Measure Setup > General > Caliper, the results
including Vmax, PGmax, PGmean, VTI, PHT, Acc, AccT, Dec and DecT will be shown on the screen.

I want to learn how to do angle correction on PW Doppler on my machine.

Prof Akhigbe 24 Apr 2024 | 14:30:30

How do I assess PW angle cursor?
