14.5.4.2 GYN Calculations in the Spectral-Doppler Mode
There are three possibilities to measure the left or right Ovarian Artery in Spectral-Doppler mode:
• Auto Trace
(chapter 14.5.4.2.1)
• Manual Trace
(chapter 14.5.4.2.2)
• Measurement of Each Item
(chapter 14.5.4.2.3)
• To measure the Fetal Heart Rate
review: Obstetric Measurements (chapter 14.3.4.4.4)
14.5.4.2.1 Auto Trace
1. After obtaining a feasible Doppler spectrum, press the [Calc] key on the control panel.
The GYN-Doppler Calculations menu appears in the menu area.
2. Select the appropriate “Measure Group” and select [Auto Trace].
The Doppler spectrum is traced automatically and the results are
displayed.
3. Select the sensitivity of the envelope curve
(to eliminate artifacts).
4. Select the Trace Mode channel of the envelope
curve (upper, both or lower).
A green line appears at the left of the spectrum.
Press the upper trackball key [Change] to move the line and readjust the start cycle (the line changes to
yellow).Press the right or left trackball key [Set] to fix the line.
A green line appears at the right of the spectrum. Press the [Change] key again (line changes to
yellow), move the line to readjust the end cycle and fixate it with [Set].
The status area shows the current function of the trackball.
If you press the right or left trackball key [Store] the measurement results are
stored in the GYN-report.

The determination of the envelope curve requires a clear and low-noise recording of the Doppler
spectrum. Otherwise the reliability of the displayed measurement results may not be ensured.
