GE Healthcare Vivid E9 with XDclear - Manual (Page 5)

Automated Function Imaging (AFI)
This software tool assesses and
quantifies left ventricular wall motion
at rest. It calculates a large set of
parameters to describe the function
of the left ventricular walls. AFI
specifically calculates peak systolic
longitudinal strain (both segmental
and global) and presents the results
as parametric images.
As part of its healthymagination
validation, a study has shown that
AFI offers potential in predicting
mortality in patients with suspected
LV impairment compared to Ejection
Fraction and Wall Motion.

Based on extensive feedback from clinicians just like you,
TTE and TEE on the Vivid E9 are all about making imaging
simple, intuitive, and quantifiable to help make your work
easy and efficient.
4D Strain
As an extension to the 4D LV Mass tool, both global
and regional strain values are calculated based upon
a spatial speckle-tracking algorithm. The end result is
presented in a Strain Bull’s-eye plot accompanied by
time-strain curves and cut planes for enhanced visual
tracking assessment.
AFI
Bull’s-eye as well as segmental traces showing
reduced longitudinal strain, likely due to right coronary
flow obstruction.
4D Auto LVQ
A mesh-based surface-tracking model, the 4D Auto
LVQ quantification tool provides you with a graphical
output of pure 4D volume data. Utilizing temporal data,
it delivers reproducible results for automatic volumes
and ejection fractions.
4D LV Mass
Using the above-mentioned mesh-based surface-tracking
model, by adding the epicardial border, an LV Mass and
an LV Mass Index is derived from the same data set.

MV Assessment
The semi-automated MV Assessment tool, now also
available on Vivid E9 for TEE and TTE, provides the
ability to include quantitative results for the mitral valve
apparatus, into the patient exam.
