8-4 Measurement
8.3 Application Measurements
The application includes the following items:

Abdomen measurements: used for measurements of abdominal organs (liver, gall bladder, pancreas
and kidney, etc.) and large abdominal vessels.

OB measurements: used for measurements of GA and EDD, to calculate the growth indices,
including the EFW. The growth estimation is determined by growth curve and fetal biophysical
profile.

Cardiac measurements: used for cardiac measurements and measurements of other parameters,
etc.

Gynecology measurements: used for the uterus, ovary and follicles, etc.

Small Part measurements: used for small parts such as thyroid.

Urology measurements: used for prostate, seminal vesicle, renal, adrenal, micturated and testicle
volume.

Orthopedics measurements: used for hip joint measurement.

Peripheral vessel measurements: used for carotid, cerebral, upper and lower extremities vessels,
etc.

EM measurements - used for EM-related full functional measurements.
