8-4 Measurement
îš„ Abdomen measurements - Used for measurements of abdominal organs (liver, gall
bladder, pancreas and kidney, etc.) and large abdominal vessels.
îš„ OB measurements - Used for measurements of fetal growth indexes (including EFW) as
well as GA and EDD calculations. The fetus can be evaluated through growth graph
analysis and fetal biophysical profile.
 Cardiac measurements – Used for left ventricle function measurements and
measurements of main artery and vein parameters, etc.
îš„ Gynecology measurements - Used for the uterus, ovary and follicles, etc.
 Small Part measurements – Used for small parts such as thyroid.
îš„ Urology measurements - Used for prostate, seminal vesicle, renal, adrenal, micturated
and testicle volume.
 Orthopedics measurements – Used for hip joint measurement.
 Vascular measurements – Used for carotid, cerebral, upper and lower extremities vessels,
etc.
 EM measurements – Used for EM related full functional measurement.
