Measurements and calculations
5-17
a
Select the calculation list that contains the measurement name.
b
Drag the caliper to the peak systolic waveform, and tap
Next
.
A second caliper appears.
c
Drag the caliper to the end diastole point on the waveform.
d
Tap
under the measurement name.
To calculate volume flow
1
On a frozen 2D or Doppler trace, tap
Calcs
.
If this control is hidden, tapping
More Controls
displays it.
2
On the calculation list, tap
Volume Flow
.
3
Calculate Volume Flow 1.
a
Measure the blood vessel diameter:
i On a frozen 2D image, on the
Volume Flow
menu, tap
Diam
.
ii Position the calipers by dragging.
iii Tap
to save the measurement.
b
Calculate the blood velocity:
i On a frozen Doppler trace, on the
Volume Flow 1
menu, tap
TAP
(peak). To use a different velocity
measurement, tap
and then choose either
Mean
or
Manual
.
ii For
Manual
, trace the waveform by dragging the calipers.
To make a correction, trace backward on the dotted line.
iii For
Peak
or
Mean
, position the vertical calipers by dragging.
iv Tap
to save the measurement.
4
Calculate Volume Flow 2.
a
Measure blood vessel diameter
i On a frozen 2D image, on the
Volume Flow 2
menu, tap
Diam
.
ii Position the calipers by dragging.
iii Tap
to save the measurement.
b
Calculate the blood velocity.
Note
Using the
Mean
option will not provide a VTI measurement.
