4D Auto MVQ
Vivid S70 / S60 – User Manual 8-67
BC092760-1EN 01
4D Auto MVQ
The 4D Auto MVQ (Automated Mitral Valve Quantification) tool
allows the user to perform computer assisted identification and
segmentation of 4D TEE images of the Mitral Valve (MV). Upon
completion of the segmentation the tool will provide metrics for
the MV annulus and leaflet during systole.
The 4D Auto MVQ tool is only on the Vivid S70 with 4D option
available when 4D is enabled.
Requirements
4D Auto MVQ is available on 4D trans-esophageal
echocardiographic (TEE) tissue data sets in replay mode only.
The results may be inaccurate when the tool is used on loops
with volume rate lower than 12 vps.
Do not use the 4D Auto MVQ 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.
• Any part of the valve or annulus is outside the ultrasound
sector.
The tool must not be used on other structures than the mitral
valve.
