• Press Left-Right Flip.
• Verify the view by annotating it as A4CH again
NOTE: You may alternatively exit AutoEF, invert the image and start
AutoEF again.
2. An automatic endocardial ROI was generated when
entering the Define ROI stage. The ROI may be edited by
clicking and dragging on the endocardial and epicardial
contours. See section ‘ROI adjustment’ on page 8-25.
3. When satisfied with the ROI, either stop moving the cursor
and wait for automatic processing or click on the Process
button. Now the system tracks the ROI with time. On
completion, it proceeds to show the results in the EF result
screen. The tracking must be visually controlled and
validated as described below.
EF results
The Results stage opens with a multi frame EF result layout.
• The running loop is shown on the left. A green dotted line
marks the inner border of the chamber. In case of poor
tracking, the system automatically displays parts of the
border in red.
• The frames with the maximal volume (ED) and minimal
volume (ES) are displayed on the right side.
NOTE: Press EF Dual to only display the ED and ES frames.
• The End Diastolic volume (EDV), the End Systolic Volume
(ESV) and the resulting Ejection Fraction (EF) are
displayed. Results for each view are summarized in a table
on the right side.
Tracking Validation
• Inspect the ROI traces for the end systole and end diastole.
• If the tracking results are visually correct, you may press
Approve and Exit to exit the tool and store the values to the
worksheet, so they can be used in a report.
