AutoEF measurements
Automated Ejection Fraction (AutoEF) is a semi-automatic
measurement tool used for measurement of the global EF
(Ejection fraction). The AutoEF tool is used as an optional
decision support tool.
The AutoEF tool is derived from a 2D speckle tracking algorithm,
which tracks and calculates the myocardial tissue deformation
based on feature tracking on 2D grey scale loops.
AutoEF is performed on either one or both apical 4-chamber or
2-chamber views, in any order.
The result is presented as Ejection Fraction value, calculated by
Simpson MOD for each view and MOD Bi-plane Ejection
Fraction for the whole LV. All values are stored to the worksheet
when approved.
Acquisition
1. Create an exam, connect the ECG device and make sure to
obtain a stable ECG trace.
