Measurement
Tools
Function
Slope
Measures the distance and time between two points and calculates the
slope.
HR
Measures the time of n (
n≤8) cardiac cycles and calculates the heart rate in
M mode image.
Velocity
Calculates the average velocity by measuring the distance and time
between two points.
7.2.3 Doppler General Measurements
Doppler general measurements refer to general measurements on PW mode images. The
measurements listed below can be performed:
Measurement
Tools
Function
Time The time interval between any two points.
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, velocity and PG (pressure gradient) of a
point on the Doppler spectrum waveform are measured.
Acceleration
Velocity and time interval between two points are measured to calculate
speed difference and acceleration.
D Trace
On the PW mode image, one or several Doppler waveforms are traced
to obtain speed and PG, etc.
PS/ED
Velocity and PG between two peaks on the Doppler spectrum to
calculate RI (resistance index) and PS/ED (peak systolic/end diastolic).
Volume Flow Blood flow through some vascular cross section per unit time.
7.3 Application Measurement
The system support following measurement types:

Abdomen measurements - Used for measurements of abdominal organs (liver, gall
bladder, pancreas and kidney, etc.) and large abdominal vessels.

Reproduction measurements- Used for measurements of animal growth indice.

Cardiac measurements- Used for left ventricle function measurements and
measurements of main artery and vein parameters, etc.

Small Part measurements
– Used for small parts such as thyroid.

Vascular measurements
– Used for vessels measurements.
