D A/B

This is a basic measurement that is only available in Spectral Doppler Mode. 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. Press Caliper and select D A/B under soft menu [1]. ‘D A/B’ is displayed 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. When the measurement is nished, its result is shown on the screen.

X

V1: Velocity at point 1

X

V2: Velocity at point 2

X

PGmax: Max Pressure Gradient

X

V1/V2: Velocity ratio

NOTE: If Application under Utility > Measure Setup > General > Caliper is set to Cardiac, results

for Vmax, PGmax, V2-V1, etc. are shown on the screen.

D Trace

This is a basic measurement that is only available in Spectral Doppler Mode. 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. Press Caliper and select D Trace under soft menu [1]. ‘D Trace’ is shown in the user information area.

2. Trace a curve. The tracing method is identical to ‘Line Trace’.

3. When the measurement is nished, its result is shown on the screen.

X

PSV: Peak Systolic Velocity

X

EDV: End Diastolic Velocity

X

RI: Resistivity Index

X

PI: Pulsatility Index

X

S/D: Ratio of PSV to EDV

X

Vmean: Average velocity.
