IT (Intracranial Translucency)
SonoIT (Sonography based Intracranial Translucency) is a system supported
measurement for Intracranial Translucency. Starting from the routinely used
midsagittal view of the fetal face, obtained for assessment of the Nuchal
Translucency and nasal bone, the ultrasound system uses a semi-automated
mode to measure the anterior-posterior diameter of the fourth ventricle
recognizable as intracranial translucency.
The workflow is identical with SonoNT.
10.3.1.3 SonoBiometry
Sono
Biometry is an alternative to the common fetal biometry measurements. It provides
system suggested measurements for BPD, HC, AC, FL,HL, Cerebellum, CM or VP which need
to be confirmed by the user or can be changed manually.
To use :
1. Press Calc on the user interface.
2. Select the measurement package OB .
3. Select the desired measurement item ( BPD , HC , AC , FL , HL , Cerebellum , CM , or VP ).
4. The calculation process starts. The result is displayed on the monitor screen. If the result
is not correct, proceed with manual correction by pressing Change or moving the
trackball cursor.
5. Press Set to accept the result and to finish the measurement.
10.3.1.4 Facial Angle Measurement
Two facial angle measurements are available:
•
FMF Angle (Frontomaxillary Facial Angle): The FMF angle is measured between a line
along the upper surface of the palate and the upper corner of the anterior aspect of the
maxilla, extending to the external surface of the forehead, represented by the frontal
bones or an echogenic line under the skin below the metopic suture that remains open.
•
MMF Angle (Mandibulomaxillary Facial Angle): The MMF angle is generated by using
the same first part and the same apex as for the FMF angle. The second part, however,
is drawn downwards and positioned so that the inner aspect of the line flushes with the
upper anterior corner of the mandible.
Note
The Facial Angle measurements are not included in the presets but need to be added
manually to a measurement group.
