Measurement
Tools
Function
HR
N intervals (n ≤ 8) are measured to calculate a PW mode derived HR
value in Beats Per Minute (BPM).
D Velocity
On the Doppler mode image, measure velocity, PG (pressure
gradient) and spectrum correction angle of a point on the Doppler
spectrum waveform and etc.
Acceleration
Measure the velocities of two points and their time interval on the
Doppler image, and calculates the acceleration, pressure gradient,
velocity difference and correction angle.
D Trace
On the PW mode image, one or several Doppler waveforms are
traced to obtain speed and PG, etc.
PS/ED
Measure the Peak Systolic (PS) velocity and End Diastolic (ED)
velocity on the Doppler spectrum, and calculates resistance index
(RI), S/D and correction angle.
Vas Area Measures the area of the vascular section of the blood flow.
9.3 Application Measurement
The system can be configured with the following application measurement packages
corresponding to the application packages (refer to "2.5 System Configuration" for
details):
„ 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 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.
„ 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.
„ Emergency measurements – Used for measurements of emergency applications.
