2. Specify two points and measure the straight distance between them. The method for

measuring a line is the same as in “2D Distance.”

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

- Vel. 1: Velocity at Point 1

- Vel. 2: Velocity at Point 2

- PGmax

- V2-V1: Velocity Change

- Time: Time Change

- Acc : Acceleration

- RI: Resistivity Index

- S/D: Systolic to Diastolic Ratio

4. A new measurement cursor appears. When more than 2 measurements are taken,

measurements are deleted in the order in which they have been taken.

The equations used for D Velocity measurement are as follows:

▐ Doppler Velocity (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.

You can calculate up to 4 sets of velocity ratios. The points representing each set are

differentiated into Point A and B.

1. Select the Flexible Soft button [1] D A/B. “D A/B” is displayed in the user

information area.

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 finished, its result is shown on the screen.

- Vel. A: Velocity at Point A

- Vel. B: Velocity at Point B

- PGmax

- A/B: Velocity Ratio

4. A new measurement cursor appears. When more than 4 sets are measured,

measurements are deleted in the order in which they have been taken.

▐ Doppler Trace

This is a basic measurement that is available in Spectral Doppler Mode only. You can
