6 Image Acquisition
• During image acquisition, the user is recommended to stably hold the ultrasound probe to
acquire fetal heart ultrasound video. If the Smart Fetal HR measurement is not satisfactory
(e.g., the heart rate cycles are not marked accurately on the M-mode image), the user can
manually modify the sampling lines of heart rate cycles on the M-mode image or change the
number of heart rate cycles. The fetal heart rate measurement result will be updated
simultaneously.
This feature is to measure the fetal heart rate automatically on M mode.
Perform the following procedure:
1. Perform B-mode scanning under Fetal Echo (High Flow), OB1 Fetal Echo, Fetal Echo (Low
Flow) exam mode.
2. Tap [Smart FHR], and the button is highlighted.
3. Press <M> on the control panel, and the system acquires M-mode image automatically. The M
mode image and the sampling line are displayed on the screen.
If necessary, tap [Smart FHR Cycle] to set the number of heart rate cycle.
4. Press <Freeze> on the control panel. The heart rate cycles are marked on the M-mode image.
And the fetal heart rate measurement result is displayed on the screen.
If necessary, tap [Smart FHR Cycle] to set the number of heart rate cycle, and the measurement
result is updated simultaneously.
