Common Measurement Methods
This section provides information on the common measurement methods used for applications.
Measurements in Spectral Doppler mode
In general, if you trace a Doppler Spectrum, you obtain results for various measurement items
automatically. There are 3 ways to trace a Doppler Spectrum.
Also, HS50/HS60 can select a specic item under the measurement menu and take measurements
individually without tracing a Doppler Spectrum.
Auto Trace
Spectrum is traced automatically. This can be enabled in the measurement menu in Spectral
Doppler mode.
1. Press Auto Trace in the measurement menu.
2. The system traces the spectrum automatically.
3. When the Trace is complete, the measurement results are displayed on the screen.
Limited Trace
Specify a measurement range, and a spectrum will be traced automatically. This can be enabled
in the measurement menu in Spectral Doppler mode.
1. Select Limited Trace in the measurement menu. A bar will appear, with which you can
specify range.
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 the Trace is complete, the measurement results are displayed on the screen.
