Follicles can be added/removed using trackball or on screen tap gesture.
SonoCNS is an option.
SonoCNS is available for 3D pre, 3D or 4D write or with a reload of a 3D/4D dataset.
Switching to another tool or visualization type deletes all SonoCNS alignments and
measurements.
SonoCNS is a method to examine the fetal Central Nervous System (CNS) based on acquired
3D/4D ultrasound volumes. The tool provides the user with a view of the TV (Transventricular),
TC (Transcerebellar), TT (Transthalamic) and MS (Mid-sagittal) plane. The required volume
can be newly acquired, re-loaded from the archive, or extracted from a 4D cine.
If no MSP or TTP is found by the SonoCNS algorythm, Expanded to accept a TTP and TVP
plane.
All controls are the same as in 3D/4D mode. Therefore only the SonoCNS relevant controls
are described here:
Start Alignment to start the SonoCNS alignment. While SonoCNS is

Before SonoCNS is used, a volume dataset of the fetal head near the TT or TV plane has to
be prepared.
1. Select SonoCNS either in 3Dpre, 3D or 4D write mode and press
tool automatically extracts and displays 4 planes (TTP, TCP, TVP, MSP).
2. Press Start Measurements to start the measurement process.
3. Decide whether to accept the displayed alignment and to transfer it to the worksheet by
