AI tool, mobile ultrasound aids ejection fraction measurement at point of care

A combination of mobile ultrasound and artificial intelligence provides a mobile solution to assess ejection fraction measurements.

The two companies collaborating on the initiative—DiA Imaging Analysis and GE Healthcare—say they have created an app that’s able to operate in the environments in which the technology is typically used.

Ejection fraction evaluation is an important diagnostic criterion that directs various treatment strategies in point-of-care settings, particularly in emergency medicine, intensive care and anesthesia.

In the collaboration, DiA’s LVivo EF cardiac decision support software is now available with GE’s new Vscan Extend handheld pocket-sized ultrasound. The capability to measure ejection fraction is important in assessing heart function. It measures—as a percentage—how much blood the left ventricle of the heart pumps out with each contraction.



Traditionally, most EF interpretation at the point of care is conducted through visual estimation, with clinician experience levels varying across different settings, so achieving an accurate ejection fraction result can be challenging. LVivo EF addresses this challenge by quickly and efficiently providing clinicians with left ventricle EF scoring and volume measurements via DiA’s proprietary AI technology and advanced pattern recognition algorithms that imitate the way the human eye identifies borders and motion.

The new capability improves accuracy and productivity, says Rob Walton, general manager of GE Healthcare’s primary care ultrasound unit.

LVivo EF is part of the DiA cardiac toolbox. The company offers additional cardiac ultrasound decision-support apps—which, like LVivo EF—are U.S. FDA-cleared and CE Marked in the European Union.
