Mindray Z60W - Doppler General Measurements

Measurement 8-3
8.2.3 Doppler General Measurements
Doppler general measurements refer to general measurements on PW/CW-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.
