D A/B
This is a basic measurement that is available in Spectral Doppler Mode only. You can specify two points
in a Spectral Doppler image and measure the velocity at each point to calculate the ratio of the velocity
between them.
1.
Sele
ct D A/B in
the
Soft Menu
[1]
.
D A/B will appear
in the user information area.
2.
Specify two points for which to measure velocity.
X Use the
Trackball
to place the cursor at the desired position and press the
Set
button.
3.
Once measurement is done, the result is displayed on the screen.
X V1 : Velocity at Point 1
X V2 : Velocity at Point 2
X PGmax : Max Pressure Gradient
X V1/V2 : The Ratio of Velocity
NOTE: If Application is set to Cardiac at Utility > Measure Setup > General > Caliper, the results
including Vmax, PGmax, V2-V1 will be shown on the screen.
