To create a new ROI trace
The system automatically displays a frame where the
endocardial border is usually clearly visible. To use another
frame, while in Define ROI stage, pause the playback by
pressing Stop. Then, use the Frame slider to select a different
frame for ROI definition.
To create a new automatic ROI, click the Reset stage symbol
. This relaunches the automatic segmentation.
Sometimes the automatic ROI may fail to capture the correct
ROI. In this case, a 3-Point ROI alternative is provided.
To generate a ROI by this method, when in
Define ROI
stage,
click on the button 3-Click . The AutoEF tool will now prompt to
click 3 landmarks. Follow the indications displayed on the
screen when placing the three points.
When the third landmark is selected, a ROI is generated and
can optionally be edited as for the automatic ROI.
NOTE: If the ROI needs to be adjusted make sure to make the changes
immediately after the ROI is displayed, before the auto
processing of the ROI begins.
NOTE: The timing when auto processing of the ROI will start is
configurable (from Config).
NOTE: The Yo-yo function is turned on to help find correct location for
the points.
