Summary: Exo has introduced FDA-cleared AI apps on its Exo Iris handheld ultrasound, enabling swift heart and lung diagnosis at the point of care.

Key Takeways

  1. Exo’s handheld ultrasound, Exo Iris, with FDA-cleared AI apps, streamlines heart failure diagnosis, especially in underserved areas, expediting care pathways.
  2. Exo’s AI provides real-time diagnostic answers for heart and lung conditions, aiding in swift and accurate treatment decisions.
  3. Exo Iris now offers pulsed-wave Doppler capabilities, broadening diagnostic opportunities in cardiac, abdominal, and vascular applications.


Medical imaging software company Exo announces the availability of its U.S. FDA-cleared cardiac and lung AI applications on Exo Iris, its handheld ultrasound device. This AI-powered medical imaging tool in a pocket-sized device enables caregivers to swiftly obtain diagnostic answers, expediting diagnosis and opening new care pathways for heart failure patients at the point of care.

Diagnosing Heart Failure at the Point of Care

The number of Americans with heart failure today is over 6.7 million and growing, posing both population health and financial challenges. Echocardiography, the primary method for heart failure diagnosis, is costly and requires highly trained sonographers. This leads to limited access to medical imaging when and where it’s needed most.

AI-powered handheld ultrasound devices make medical imaging more accessible, offering simplified diagnostics. These technologies aid health systems and caregivers, especially those in rural or under-resourced areas, in obtaining and interpreting heart and lung images, speeding up diagnosis and treatment processes.

Sandeep Akkaraju, co-founder and CEO of Exo, states, “It’s time for a reimagined approach to addressing heart failure at scale. That’s why Exo is putting AI-empowered medical imaging in the hands of every caregiver, no matter their specialty. Exo’s AI is simple to use, reproducible, and objective, contributing to more accessible and reliable healthcare for all.”

Real-Time Diagnostic Solutions

Exo trains its AI applications on over 100,000 images from point-of-care ultrasound exams conducted in real-world settings. Rigorous validation across various patient populations, health conditions, and diagnostic scan types ensures reliability, even on less-than-perfect scans.

Exo’s AI provides real-time data, enabling quick answers to diagnostic questions like, “Is my patient’s shortness of breath related to a heart condition or a lung condition?” Exo’s lung AI identifies B-lines, indicating pulmonary edema, while the cardiac AI measures left ventricle ejection fraction and stroke volume, aiding in timely patient care.

Ted Koutouzis, clinical instructor in emergency medicine at Northwestern Medicine, comments, “Exo’s cardiac and lung AI applications are a game-changer. Now I have a fast and reliable clinical tool to help easily distinguish between COPD and CHF patients for precise and timely care. These applications also open ultrasound technology to a whole new set of POCUS users, especially those with limited experience.”

In addition to cardiac and lung AI, Exo Iris now features pulsed-wave Doppler capabilities, expanding diagnostic opportunities in cardiac, abdominal, and vascular applications.
