The 4D Auto AVQ (4D Automated Aortic Valve Quantification)
tool allows the user to perform computer assisted alignment of
4D TEE images of the Left Ventricular Outflow Tract (LVOT) as
well as segmentation of the LVOT and aortic root. Upon
completion of the segmentation the tool will provide metrics for
the aortic annulus diameter and area.
The 4D Auto AVQ tool is only available on Vivid S70.
The 4D Auto AVQ tool is available on 4D trans-esophageal
echocardiographic (TEE) tissue data sets in replay mode only.
The tool cannot be used on acquisitions with volume rate lower
than 12 vps.
Do not use the 4D Auto AVQ tool if:
• The image quality is poor.
• The acquisition has stitching artifacts (see page 6-8 on
how to avoid stitching artifacts).
• The acquisition has significant reverberation artifacts.
The tool must not be used on other structures than the aortic
valve.
