5.1.2 Conventional measure in M mode
M mode measurements are as follows:
Measure item Function
Distance
Measure the distance between any two points on a vertical line at a given
time.
Time Measure the time interval between two points on the M image.
Gradient
The average slope between two points is calculated by measuring the
distance and time of the two points.
Heart rate
On M cardiogram, the interval between two cardiac cycles was measured
and the heart rate was calculated.
5.1.2 Conventional measure in Doppler mode
PW mode measurements are as follows:
Measure item Function
Dspeed
On Doppler images, the velocity and pressure difference at some point in
the Doppler spectrum waveform are measured.
PS/ED
The velocity (PS) of the systolic peak point and the velocity (ED) of the end
diastolic phase were measured on the blood flow waveforms in Doppler
images and their pressure difference and resistance index RI, ratio were
calculated.
D trace
The clinical parameters such as velocity, pressure difference, index and so
on were obtained by depicting the Doppler spectrum waveforms of two
cycles.
