46 Measurements
3 Press the SELECT key.
A second caliper appears.
4 Using the touchpad, position the second caliper
at the end diastole on the waveform.
See “To save a measurement to a calculation
and patient report” on page 43.
To measure time duration (Doppler)
1 On a Doppler spectral trace, press the CALIPER
key.
2 Press Time on-screen.
A vertical caliper appears.
3 Using the touchpad, position the caliper where
desired, and press the
SELECT key.
A second caliper appears.
4 Using the touchpad, position the second caliper
where desired, and press the
SELECT key.
To trace manually (Doppler)
1 On a frozen Doppler spectral trace, press the
CALIPER key.
2 Select Manual on-screen.
A single caliper appears.
3 Using the touchpad, position the caliper at the
beginning of the desired waveform, and press
the
SELECT key.
If calipers are not positioned correctly, the result
is inaccurate.
4 Using the touchpad, trace the waveform.
To make a correction, select Undo on-screen,
backtrack with the touchpad, or press the
BACKSPACE key.
5 Press the
SET key.
The measurement results appear.
See “To save a measurement to a calculation
and patient report” on page 43.
To trace automatically (Doppler)
After tracing automatically, confirm that the
system-generated boundary is correct. If you are
not satisfied with the trace, obtain a high-quality
Doppler spectral trace image, or trace manually.
(See “To trace manually (Doppler)” on
page 46.)
1 On a frozen Doppler spectral trace, press the
CALIPER key.
2 Select Auto on-screen.
A vertical caliper appears.
3 Using the touchpad, position the caliper at the
beginning of the waveform.
If calipers are not positioned correctly, the
calculation result is inaccurate.
4 Press the
SELECT key.
A second vertical caliper appears.
5 Using the touchpad, position the second caliper
at the end of the waveform.
6 Press the
SET key.
The measurement results appear.
See “To save a measurement to a calculation
and patient report” on page 43.
Automatic trace results
Depending on the exam type, the results from
automatic tracing include the following:
• Velocity Time Integral (VTI)
• Peak Velocity (Vmax)
• Mean Pressure Gradient (PGmean)
• Mean Velocity on Peak Trace (Vmean)
• Pressure Gradient (PGmax)
• Cardiac Output (CO)
• Peak Systolic Velocity (PSV)
• Time Average Mean (TAM)*
• +/× or Systolic/Diastolic (S/D)
