2 Drag your finger on either the touchpad or the touchscreen to position the caliper to a peak velocity
waveform.
To measure Velocities, Elapsed Time, Ratio, and Resistive Index (RI) or Acceleration
1 On a frozen Doppler spectral trace, tap Calipers .
A single vertical caliper appears.
2 Using the touchpad or the touchscreen, position the caliper to a peak velocity waveform. Tap to set
the position.
A second vertical caliper appears.
3 Drag your finger on either the touchpad or the touchscreen to position the second vertical caliper at the
end diastole on the waveform, and then tap .
To make a correction, tap Delete above the right knob or press the right knob.
Elapsed time between the times indicated by the two calipers is calculated. Measured velocities are given
as results, and a generic ratio between the velocities indicated by the two calipers is calculated.
If the absolute value of the earlier velocity is less than that of the later velocity identified by the calipers,
Acceleration is calculated; otherwise, in non-cardiac exams, RI is calculated.
To measure time duration
1 On a frozen Doppler spectral trace, tap Calipers .
2 Navigate to the second page by tapping the arrow.
3 Select Time .
A vertical caliper appears.
4 Using the touchpad or the touchscreen, position the caliper where desired, and then tap .
A second vertical caliper appears.
5 Using the touchpad or the touchscreen, position the second caliper where desired.
To perform manual trace measurements in Doppler
1 On a frozen Doppler spectral trace, tap Calipers .
2 Navigate to the second page by tapping the arrow.
