Chapter 39: Analyzing PW Doppler Mode and PW Tissue Doppler Mode images
You can apply these traces in real-time to the data in your cine loop acquisition
buffer or to an acquired cine loop.
f To apply an automatic trace of the frequency waveform:
1. While you view a saved image from the Study Browser or an image that is
acquired but not stored during an image acquisition session, press
Measure
and toggle to view the measurement tools panel.
2. Select the appropriate auto trace option in the Peak or Mean frequency drop-
down boxes as described in the following tables.
3. To adjust the VTI threshold for a trace, press
]
to increase and
[
to
decrease.
Peak
Option Description
none The system does not apply a trace.
+
Applies a blue trace to all positive peak frequency signal traces (flow moving toward the
transducer face) along the entire cine loop.
-
Applies a pink trace to all negative peak frequency signal traces along the entire cine
loop.
+ / - Applies both the positive as well as the negative peak frequency traces.
