11. Press the Set button to fix the PSV velocity caliper and activate the MDV

velocity caliper.

NOTE: If the absolute value of the MDV velocity result is greater than the current

PSV result, the MDV and PSV result displays are swapped and the caliper

becomes a PSV caliper. The converse is also true, when the absolute value of the

PSV velocity result is less than the current MDV result.

NOTE: Pressing the Set button again toggles the active caliper selection between

the first and second velocity calipers, allowing positional corrections to be made to

both caliper instances within the strip image.

12. Use the Trackball to position the caliper to the desired location within the PW

Doppler strip display.

13. Press the Measure button to remove the PI tools and exit Measure mode.

Acceleration Acceleration (Accel) is defined as DV/DT, where DV is the velocity difference and

DT is the time interval between two points as delineated by two concurrent PW

Velocity calipers positioned within the same PW Doppler strip.

• Only a single instance of this tool can exist at any one time.

•The DDB displays both the Delta Velocity and Delta Time Results and their

associated Accel calculation result, and continuously updates them when the

user positions either caliper within the PW Doppler strip image.

 To Measure Acceleration (Accel)

1. Freeze the display with a PW Doppler strip image.

2. Press the Measure button.

3. Highlight and select Accel.

4. The first velocity caliper will be displayed.

5. Use the Trackball to position the caliper to the desired location within the PW

Doppler strip display. At this time, the DDB only displays the velocity result.

6. Press the Set button to fix the first velocity caliper and activate the second

velocity caliper.

NOTE: The delta velocity, delta time, and acceleration results are calculated and

displayed once both velocity calipers have been activated.

7. Use the Trackball to position the caliper to the desired location within the PW

Doppler strip display. The DDB continuously updates the Time, Velocity, and

Accel results as the user positions the caliper within the strip image.
