Operation Manual
■
Limited Trace
If you specify a measurement range, a spectrum is traced automatically. It is enabled in the menu in
Spectral Doppler Mode.
1.
Press Limited Trace in the Measurement menu. A bar appears allowing you to specify a measurement
area.
2. Specify the measurement range.
▶
Place the bar at a desired position with the Trackball, and press the Set button.
3. The system traces spectrums within the specied range automatically.
4. When Trace is complete, the measurement results are displayed on the screen.
■
Manual Trace
A spectrum is traced manually. It is enabled in the menu in Spectral Doppler Mode.
1. Press Manual Trace in the Measurement menu. A measurement cursor appears over a spectrum.
2. Trace the spectrum. The measuring method is the same as in “D Trace.”
3. When Trace is complete, the measurement results are displayed on the screen.

Itemized Measurement
In the Measurement menu, select an individual item and take a measurement.
1. Press the Calculator button on the control panel after obtaining a desired image.
2. Select a desired item in the Measurement menu. The “+” cursor appears over a spectral waveform.
3. Position the “+” cursor and press the Set button.
4. The measurement results for the selected item are displayed on the screen.
Measurement items for Doppler Spectrum are as follows:
Item Type Unit Equation
PSV (Peak Systolic Velocity) Velocity cm/s or m/s
EDV (End Diastolic Velocity) Velocity cm/s or m/s
TAMV (Time Average Mean Velocity) Velocity cm/s or m/s
TAPV (Time Average Peak Velocity) Velocity cm/s or m/s
PGmean (Mean Pressure Gradient) Calculation mmHg
PGmax (Max Pressure Gradient) Calculation mmHg 4 × PSV
