The final segmentation result is shown along with a graph
showing the aortic annulus area in relation to the SAX plane
lateral position (distance from aortic valve).
Two layouts are available by use of the Layout button on the
Vivid S70 / S60 control panel and the Layout button in the
user interface on EchoPAC Software Only (see
Figure 8-46).
The user can freeze the loop and navigate the frames. A
green vertical line will appear at the measurement frame
(see Figure 8-46).
The following measurements are available:
• AA diameter: diameter calculated based on the
perimeter of the segmentation in the aortic annulus
plane at mid-systole
• AA max diameter: length of the major semi-axis of an
ellipse fit to the aortic annulus at mid-systole.
• AA min diameter: length of the minor semi-axis of an
ellipse fit to the aortic annulus at mid-systole
• AA area: area of the detected aortic annulus at
mid-systole
