1. Press the Sofmenu button [1] Distance to select Doppler Velocity (A/B). “Doppler Velocity (A/B)” is dis-

played on the left side of the screen.

2. Specify two points to measure velocity for.

▶

Place the cursor at a desired position with the trackball, and press the Set button.

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

▶

V_A: Velocity at Point A

▶

V_B: Velocity at Point B

▶

RI: Resistivity Index

▶

A/B: The Ratio of Velocity

Doppler 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 aver-

age velocity of blood ow.

1. Press the Sofmenu button [1] Distance to select Doppler Trace. “Doppler Trace” is displayed on the

left side of the screen.

2. Trace a curve. The method for measuring a curve is the same as in “2D Distance (Trace).”

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

▶

dT: Change in Time

▶

VTI: Velocity Time Integral

▶

Mean V: Mean Velocity

▶

Peak V: Peak Velocity

▶

Mean G: Mean Gradient

The equations used for D Trace measurement are as follows:

1 2 ... 133 134 135 136 137 138 139 140 141 142 143 ... 441 442
