Acquisition
1. Create an exam, connect the ECG device and make sure
to obtain a stable ECG trace.
2. Acquire 2D grey scale cineloops of an Apical long axis
(APLAX) view, an Apical 4 chamber view and an Apical 2
chamber view.
3. Store the loop (must store).
Note: It is recommended to acquire all three apical views
sequentially in order to get similar heart rate in all views.
• The frame rate should be between 37 and 80 frames per
second. A high frame rate is recommended for high heart
rate.
• The scanner should be configured to store at least 100 ms
before and after each heart cycle,
- or -
• The scanner should be configured to store 3 loops or more.
• If the stored loop contains more than one heart cycle, the
analysis will be done on the second last heart cycle.
• The entire myocardium should be visible.
• A depth range that includes the entire left ventricle should
be used.
Starting AFI
