3 Using the touchpad, position the caliper at the beginning of the desired waveform, and press the SELECT
key.
Note
4 Using the touchpad, trace the waveform.
a To make a correction, select Undo on-screen, backtrack with the touchpad, or press the backspace key.
b Press the SET key. The measurement results appear. Refer to
patient report" on page 67.
To trace automatically (Doppler)
After tracing automatically, confirm that the system-generated boundary is correct. If you are not satisfied
with the trace, obtain a high-quality Doppler spectral trace image, or trace manually. See
(Doppler)" on page 71.
1 On a frozen Doppler spectral trace, press the CALIPER key.
2 Select Auto on-screen. A vertical caliper appears.
3 Using the touchpad, position the caliper at the beginning of the waveform.
a If calipers are not positioned correctly, the calculation result is inaccurate.
b Press the SELECT key. A second vertical caliper appears.
4 Using the touchpad, position the second caliper at the end of the waveform.
5 Press the SET key. The measurement results appear. Refer to
patient report" on page 67.
Automatic trace results
Depending on the exam type, the results from automatic tracing include the following:
Velocity Time Integral (VTI)
Peak Velocity (Vmax)
Mean Pressure Gradient (PGmean)
Mean Velocity on Peak Trace (Vmean)
Pressure Gradient (PGmax)
End Diastolic Velocity (EDV)
72
If calipers are not positioned correctly, the result is inaccurate.
Cardiac Output (CO)
Peak Systolic Velocity (PSV)
Time Average Mean (TAM)
+/× or Systolic/Diastolic (S/D)
Pulsatility Index (PI)
Resistive Index (RI)
